Summary
The absence of legal cause must be examined together with the link between the benefit derived from another's property or labor and the resulting loss.
1.1The Standard by Which the Path Opens
The mere fact that another has obtained something does not by itself create a duty to return it to me. Return targets the performance that can be recovered, while damages target the harm within the scope of liability; therefore, I take the view that the overlapping of the same items is not itself a ground for permitting duplicate recovery. Accepting this conclusion, what remains is whether a claim is accepted merely because the other party obtained a benefit. In this scene, the recipient, B, asserts that he received the performance sent by plaintiff A but learned later that there was no cause for payment. The absence of cause is not established by B's assertion alone, and the question is over what scope and under what requirements one must confirm before this avenue of relief opens.
The provision corresponding to this question is Article 741 of the Civil Act. It provides: "A person who, without any ground in law, has obtained a benefit from the property or labor of another and thereby caused damage to another shall return that benefit." This provision designates the person who obtained the benefit, that is, the recipient, as the person liable to return. That benefit must have been obtained, without any ground in law, from the property or labor of another, and it must have thereby caused damage to another. What the author calls unjust enrichment here is a benefit obtained from the property or labor of another, without any ground in law, and causing damage, and the provision does not address other issues.
The elements required by this provision do not coalesce into one. The fact that the recipient obtained some benefit does not by itself establish a claim; the point that the benefit derived from the property or labor of another without any ground in law, and the connection that damage was thereby caused to another, must be established together. Thus the author's conclusion is that this avenue of relief opens where the connection between a benefit without cause and damage is recognized, no restriction on return applies, and the scope, such as good or bad faith and existing benefit, has been specified. The confirmation of the benefit and the determination of the absence of cause are distinct stages of judgment and must be distinguished.
The strongest of the counterarguments is aimed at the proposition that a formal cause can justify an unjust benefit. It contends that, so long as a nominal contract or a documentary ground remains, the recipient can rely on that form to assert retention, and that unless this is broken, a person who spent another's money escapes return, giving rise to inconvenience and loss. Without erasing the merit of the counterargument, the answer set by the author does not change. The existence of a benefit alone cannot establish the absence of a ground in law. What the formal cause justifies is examined separately, and one first confirms whether the recipient's benefit possesses the absence of a ground in law and the connection with damage.
The facts confirmed in this scene are that recipient B received the performance sent by plaintiff A and asserts that he learned later that there was no cause for payment. These facts correspond to the entries of the records in the unjust enrichment determination. Payment and cause, awareness at the time of payment, attribution of the unlawful cause, existence of the benefit, and later awareness are those entries. B's later awareness is asserted in the present scene, while awareness at the time of payment and the size of the remaining benefit have not been confirmed. Accordingly, whether the connection of the benefit and the restriction on return apply remains undetermined. If it is confirmed that the unlawful cause lies only with the recipient, the exclusion of return merely on the ground of an unlawful payment is corrected.
Accordingly, one does not simply return a benefit that another has obtained; the absence of a ground in law and the connection with damage, together with a specified scope and specification of the claim, must all be confirmed before this avenue of relief opens. That this entrance has opened means that the claim for return crosses the threshold of adjudication; it does not mean that actual payment, delivery, or recovery has already taken place. That unconfirmed items remain leaves matters not in a state of no relief but in a state of being undetermined. Whether the formal cause justifies, and any change of scope according to the recipient's knowledge, are not determined. If there was no debt, is recovery always available?
1.2The Conditions That Block Relief
This assertion alone does not determine whether B came under an obligation to return. For the return stage to open, one must consider together that the benefit and the damage arose from the same performance and that there was no ground in law either. What the preceding stage left behind was that the overlapping of the same items did not mean that duplicate recovery was permitted. There is no need to re-argue that conclusion here. What is asked now is whether one can recover if the other party obtained a benefit, and what the conditions are that bar return.
The relevant provision is what Article 741 of the Civil Act sets out as the content of unjust enrichment. The subject it designates is a person who obtained a benefit from the property or labor of another and caused damage; the act is the return of that benefit; and the condition is that the absence of a ground in law and the connection between benefit and damage are established together. Here, the absence of a ground in law means the absence of a cause for payment, and the connection between benefit and damage means the circumstances by which the same performance disadvantaged one side.
That these conditions are required together is the criterion of judgment at this stage. The mere fact that the benefit B received was large does not establish the absence of a ground in law. If there was a formal cause for payment, what that cause was must first be determined, and the fact that there was none must be confirmed separately. Whether the same performance simultaneously produced A's damage and B's benefit is also examined separately. If there is a benefit but no connection with damage, the matter does not fall within the framework of return prescribed by the provision. If these two stages are mixed, the size of the benefit becomes itself the evidence of the absence of cause. This section does not permit such a determination. This is why the two conditions must be examined separately.
The strongest of the counterarguments starts from the proposition that a formal cause can justify an unjust benefit. Even if B asserts that he learned later that there was no cause for payment, if, at the time of payment, the cause appeared lawful in B's hands, that form may protect A — such is the logic. Added to this is the loss and inconvenience that, if liability is narrowed to existing benefit, a person who spent another's money avoids return. What the formal cause was, and whether that cause supported the actual performance, must be determined first; if return is recognized on the ground of the size of the benefit without that confirmation, one skips over the place of justification pointed out by the counterargument. The protective interest identified by the counterargument remains, but the order of determination does not change.
What can be confirmed in this scene is that B received A's performance and asserts that he learned later that there was no cause for payment. Comparing this fact with the conditions of the provision, among payment and cause, awareness at the time of payment, the existence of the benefit, and later awareness, the payment itself and the assertion of later awareness are disclosed, but the absence of a cause for payment, the connection with damage, and the scope of the remaining benefit are not determined by the scene alone. Whether B discharged the obligation knowing that no debt was owed, and whether the matter falls under the restriction on return for a performance for an unlawful cause, are also not determined in this scene. Accordingly, the scope in which the cause for payment, B's knowledge, or the remaining benefit cannot be confirmed remains undetermined. Undetermined does not mean no relief.
The conclusion this section permits is narrow. Only where the absence of a ground in law and the connection between benefit and damage are recognized together, no restriction on return applies, and the scope is specified, does the stage of return for unjust enrichment open. Conversely, where one discharged the obligation knowing that no debt was owed, or where the matter falls under the restriction on return for a performance for an unlawful cause and no statutory exception applies, the avenue of relief closes if any one of the statutory requirements is not met. One cannot say that the avenue opens merely because a benefit was obtained, nor can one categorically assert that it closes merely because the formal cause has not been confirmed. Unconfirmed items are left unconfirmed, and only judgments conforming to the foregoing conditions are retained.
1.3The Boundary That Remains When There Is No Data
Then, in the question whether recovery is possible when the other party obtained a benefit, what remains is what one has failed to confirm such that judgment must be deferred. From the same standpoint, this question advances beyond the existence of the performance to the dimension of inquiring whether the materials necessary for judgment have been assembled. What remains is how to divide the items that can be determined from those that cannot.
Article 741 of the Civil Act addresses the content of unjust enrichment. The provision provides that a person who, without any ground in law, has obtained a benefit from the property or labor of another and thereby caused damage to another shall return that benefit. This provision takes the subject to be a person who obtained a benefit from the property or labor of another, the act to be the return of that benefit, and the conditions to be the absence of a ground in law and the causing of damage. These three elements are not judged separately but considered together in a single chain. Accordingly, whether the benefit derived from the property or labor of another, and whether that benefit led to that person's damage, must be confirmed together before the requirement of the provision is treated as satisfied.
Because this provision does not take only the presence or absence of a benefit as its standard, the adjudication is divided into two stages. First, the connection between the benefit from the property or labor of another and the damage thereby caused must be confirmed; next, it must be confirmed whether that benefit remained without any ground in law. The reason for examining the connection first is that, without the correspondence of which side gained and which side lost, the very object on which to ask about the presence or absence of a ground in law does not arise. Conversely, if the confirmation of the ground in law does not follow, then even if there is a benefit, the ground for imposing an obligation to return remains unestablished. If one mixes these two stages and determines the absence of cause merely because a benefit is visible, the result is to omit the confirmation of connection and cause required by the provision.
A formal cause can justify an unjust benefit. Where a formal cause was attached to the payment, whether that cause corresponds to a ground in law becomes an issue of the claim for return, and the counterargument is raised that the existence of an apparent cause alone can justify an unjust benefit. The loss targeted by such a counterargument is the disadvantage and inconvenience borne if the recipient, having already spent that benefit, is held liable to return it. The observation that narrowing liability to existing benefit results in a person who spent another's money avoiding return proceeds from the same line. Yet even if a formal cause remains, the existence of a benefit alone cannot establish the absence of a ground in law. Where the substance of the cause is unconfirmed and only the form remains, one can no more categorically assert that the form justifies the unjust benefit.
What is confirmed in this scene is nothing more than B's assertion of later awareness concerning the receipt of the performance and the absence of a cause for payment. From what property or labor the performance derived, whether the benefit that performance left with B still remains, and how that benefit is connected with A's damage, are not determined in the scene. What the cause for payment itself was, and when B came to know that it was absent, are also not particularized. The judgment records retain the entries of payment and cause, awareness at the time of payment, attribution of the unlawful cause, existence of the benefit, and later awareness, but from the scene above alone those entries are not filled. Unconfirmed items do not mean the absence of a benefit, nor do they mean the denial of the liability to return, and thus remain undetermined.
What this section permits is no more than the judgment of distinguishing such matters as undetermined rather than as impossibility of return when the cause for payment, the recipient's knowledge, or the remaining benefit cannot be confirmed, and leaving them so. The recognition or exclusion of the liability to return, and the determination of its scope, are not rushed at this stage, and judgment proceeds as far as the confirmed entries are filled. To categorically assert that the liability did not arise merely because the same items cannot be confirmed is a direction this section does not permit; conversely, filling unconfirmed items with presumptions to fix liability crosses the same limits.
1.4The Records Needed for Determination
The conclusion carried forward from the preceding stage continues in a single sentence: the items targeted by return and damages differ, so the overlapping of the same items does not become a ground for duplicate recovery. Now the question is whether plaintiff A can recover that benefit merely because the other party obtained it, and what records must remain in order to adjudicate that stage.
The provision corresponding to this question is found in Article 741 of the Civil Act. Here, the person liable to return is a person who obtained a benefit from the property or labor of another without any ground in law, and that benefit must be connected with damage caused to another.
That two things are required together in this provision is the criterion at this stage. The mere fact that recipient B obtained a benefit does not establish the obligation to return; it must also be recorded together that the benefit came from a performance treated as causeless and is connected with A's damage. The Records are fixed at five entries: payment and cause, awareness at the time of payment, attribution of the unlawful cause, existence of the benefit, and later awareness.
Against this standard, the counterargument arises that a formal cause can justify an unjust benefit. It is contended that once the benefit alone is specified there is no ground to bar return, and that narrowing liability to existing benefit allows a person who spent another's money to avoid return. Yet the existence of a benefit alone cannot establish the absence of a ground in law, and only where the absence of cause and the connection with damage are recorded together can the stage be passed.
This assertion corresponds to the entries of payment and later awareness, but B's awareness at the time of payment, the attribution of the unlawful cause, and the existence of the remaining benefit are not confirmed in the scene. Accordingly, the stage of return cannot be determined on this scene alone, and unconfirmed items are left undetermined.
What this section permits is adjudicating the stage by the recorded entries; what it does not permit is filling absent records with presumptions.
1.5Circumstances That Change the Decision
As noted above, the view was taken that restitution aims at the performance to be recovered while damages aim at the harm within the scope of liability, so that the mere fact that the same items are computed together does not mean that double recovery is permitted. On that premise, the questions to be addressed this time are whether restitution can be obtained when the other party has gained a benefit, and what change overturns a stage determination already made. The objection that a formal cause can justify the unjust enrichment is directed at this question, but the answer is settled separately while maintaining the foregoing distinction.
The provision that sets out the basic scene in which a claim for restitution arises is Article 741 of the Civil Act. That provision states: "A person who, without legal ground, obtains a benefit from another's property or services and thereby causes damage to that other shall return that benefit." The subject indicated by this wording is a person who has obtained a benefit from another's property or services, and the act is the causing of damage to that other by obtaining that benefit. The conditions under which the obligation to return arises are set, together, as the case in which there is no legal ground while benefit and damage are linked together. This section addresses only this question raised by the wording of that provision.
Connecting that wording with the conclusion of this section makes the criterion for the judgment excluding restitution clear. Unjust enrichment means a benefit obtained without legal ground from another's property or services and causing damage, and here the linkage of benefit and damage is an indispensable step of judgment. Thus one cannot determine, merely by looking at the benefit obtained by one person, that there was no legal ground; one must look together at whether it was obtained from another's property or services and whether damage was linked to it as a result. Moreover, even where restitution has been barred on the ground of an unlawful performance, if it is confirmed that the unlawful cause lies solely with the recipient, the exclusion of restitution maintained on that ground alone is corrected and the stage determination is begun anew. The reason for distinguishing these two judgments—namely, the judgment that looks at the linkage of benefit and damage and the judgment that discards the existing bar—is that the former sets the basic requirements of the claim for restitution while the latter sets the conditions for withdrawing a restriction already imposed.
The objection raised most forcefully in this section is the contention that a formal cause can justify the unjust enrichment. The loss targeted by that contention is the result whereby a person who has already spent another's money escapes restitution liability by invoking a formal cause; the inconvenience lies in having to leave in place a benefit that does not appear justified; and its value rests on the idea that so long as the benefit remains, it should be corrected through restitution. However, the foregoing answer is that the absence of legal ground cannot be confirmed by the mere existence of the benefit, and this does not mean that the contention that a formal cause unconditionally justifies the benefit is correct, but only that the absence of cause cannot be confirmed by the mere fact that a benefit has been observed. Without erasing the circumstance that the benefit remains, the requirements for determining the obligation to return are considered not to be satisfied by the existence of the benefit alone.
The facts in this scene relevant to this question are that the recipient B claims to have received the performance sent by plaintiff A, and to have learned later that there was no ground for that payment. That there was a performance, that a benefit accrued to the recipient, and that there was no ground for payment are items to be confirmed in light of the framework of the absence of legal ground and the benefit from another's property set out in Article 741 of the Civil Act. However, this scene alone does not determine whether damage was linked to another, to whom the unlawful cause is attributable, or how much benefit remains; and if such items cannot be confirmed from the records, they remain undetermined. In particular, in view of the assumption that it has been confirmed that the unlawful cause lies solely with the recipient, the exclusion of restitution on the ground of an unlawful performance is corrected by that confirmation alone and the determination is redone from the stage onward, but without that confirmation no new conclusion can be settled.
The boundary between the conclusions this section permits and those it does not can be summarized as follows. The mere fact that the other party has obtained a benefit does not establish a claim for restitution; the absence of legal ground, the benefit from another's property or services, and the linkage of damage must be confirmed together; and if it is confirmed that the unlawful cause lies solely with the recipient, the exclusion of restitution based solely on an unlawful payment is corrected, the existing bar and effect determinations are discarded, and the determination is redone from the stage onward. By contrast, the conclusion that the absence of legal ground is confirmed by the mere existence of the benefit is not permitted by this section, nor does it hold that relief is immediately impossible merely because items that cannot be confirmed remain.
1.6The Strongest Counterargument and the Answer
Can restitution be obtained if the other party has obtained a benefit? In answering this question, the foregoing analytical step left only this: because restitution and damages aim at different objects, the overlapping of the same items does not itself mean double recovery. Now, in the scene in which the recipient B claims to have received the performance sent by plaintiff A but to have learned later that there was no ground for payment, the objection is raised that a formal cause can justify the unjust enrichment. Does the mere circumstance that the benefit remains also confirm the absence of legal ground?
The material for answering this question is Article 741 of the Civil Act. That provision declares: “A person who, without legal ground, obtains a benefit from another's property or services and thereby causes damage to that other shall return that benefit” (Civil Act, Article 741). The subject set by this wording is a person who has obtained a benefit from another's property or services, and the act is the causing of damage to that other by having obtained the benefit. The conditions required by the provision are the case in which the obtaining of the benefit and the occurrence of damage are established together without legal ground, and, as the wording stands, the object to be recovered is the benefit obtained. Thus far is the exposition of the range of this provision corresponding to this section.
The reason this wording places the two requirements side by side is that the existence of the benefit and the absence of legal ground are different steps of judgment. The fact that the benefit remains specifies the substance of the object of restitution, whereas the absence of legal ground is the requirement that screens whether the obtaining of that benefit is unjustified. Accordingly, the wording's demand that these two elements be looked at together cannot be read to mean that the absence of cause can be drawn in by the confirmation of the benefit alone. This judgment also aligns with the conclusion that has been held. Here, unjust enrichment means a benefit obtained without legal ground from another's property or services and causing damage.
The objection that a formal cause can justify the unjust enrichment draws its force from the standpoint of loss. If liability is narrowed to existing benefit, the result is that a person who has spent another's money avoids restitution. This observation targets precisely the inconvenience that a person deserving of blame can hide behind the size of the remaining benefit and reduce liability. However, the defined scope for answering this objection does not widen. In other words, the discussion narrowing the scope of restitution liability cannot change the criterion for confirming the absence of cause, and the conclusion is maintained even as the adverse result pointed out by the objection remains.
Among the facts appearing in the synthetic scene, two touch upon this judgment. First, the recipient B received the performance sent by plaintiff A. Second, B claims to have learned later that there was no ground for that payment. These facts show only the questions of receipt of the performance and subsequent recognition, and do not themselves prove the separate requirement of the absence of legal ground. The scene fixes no year, amount, or commencement date, and does not specify the cause of the performance, the state of knowledge at the time of payment, or whether the benefit subsists. Accordingly, whether the absence of cause and the linkage of damage are recognized cannot be confirmed on this scene alone, and remains unverified. Where the ground for payment or the recipient's knowledge and the remaining benefit cannot be confirmed, the determination of effect also remains undetermined.
The conclusion this section permits is narrow. It confirms that obtaining a benefit from another's property or services and causing damage constitutes the threshold of restitution, but it does not confirm the absence of legal ground by the mere existence of the benefit. Nor does it mean that a person who retains a benefit is unconditionally exempt from liability, and still less that a formal cause immediately justifies the unjust enrichment. The task of confirming the existence of the benefit and the task of confirming the absence of cause each require their own materials.
1.7The Link to the Application and the Dispositive Part
The preceding section accepted the premise that the absence of legal ground cannot be confirmed by the mere existence of the benefit. Against that premise, the question to be addressed this time is whether, if the other party has obtained a benefit, the person claiming restitution can recover that benefit. Whether an obligation to return arises immediately on the strength of such an assertion alone must be examined through the wording of the following provision.
Article 741 of the Civil Act provides: “A person who, without legal ground, obtains a benefit from another's property or services and thereby causes damage to that other shall return that benefit.” In this wording, the subject of the obligation to return is a person who has obtained a benefit from another's property or services. The act spoken of here is the obtaining of that benefit, in a case where damage has thereby been caused to another. And there must be no legal ground for the obtaining of the benefit. This provision places the ground of restitution in the linkage between the obtaining of the benefit and the causing of damage, and asks together whether that benefit was obtained without legal ground.
Accordingly, the wording of this provision requires side by side the obtaining of the benefit, the absence of legal ground, and the damage resulting therefrom. The mere fact that the other party has obtained a benefit does not determine the obligation to return; one must look together at whether that benefit came from another's property or services, whether damage followed to that other, and whether there was no legal ground. The reason the obtaining of the benefit and the absence of cause must be viewed separately is that the former indicates what benefit arose, and the latter indicates the ground for returning that benefit.
Against this point, the objection is raised that a formal cause can justify the unjust enrichment. If a ground for payment appears to exist in documents, or if a performance of prescribed form has passed between the parties, the form itself can make the benefit appear to possess a legal ground. The loss targeted by this objection lies in the inconvenience of being unable to protect the reliance of the person who established the form and to maintain the stability of performances. Even where a formal cause appears, the obtaining of the benefit and the absence of legal ground each remain matters to be confirmed.
Placing the fact that recipient B received the performance of plaintiff A against the foregoing conditions, it counts as confirmed that a benefit accrued to B. However, whether that performance had a legal ground, and whether damage followed to A as a result, cannot be determined on this scene alone. B's claim to have learned later that there was no ground for payment indicates only the point in time of recognition, and does not prove the absence of cause itself. Accordingly, the parts in which the ground for payment or the linkage of damage is not confirmed remain undetermined.
The conclusion this section permits is that one cannot claim restitution merely because the other party has obtained a benefit, and that the absence of legal ground, the benefit from another's property or services, and the linkage of damage must be looked at together. Conversely, it is not permitted to confirm the absence of legal ground by the single fact that a benefit arose, or to recognize the obligation to return immediately. To confirm the absence of legal ground by the mere existence of the benefit would depart from this criterion of judgment.
1.8The Scope This Section Undertakes
On the premise of this distinction, what must now be asked is whether restitution can be claimed immediately when the other party has obtained a benefit. In this scene, whether B's subsequent recognition itself is the ground of the obligation to return is a matter to be judged separately.
As the wording for answering this question, Article 741 of the Civil Act provides as follows: “A person who, without legal ground, obtains a benefit from another's property or services and thereby causes damage to that other shall return that benefit.” (Civil Act, Article 741) This wording respectively sets the subject of the obligation to return as the person who obtained the benefit, the ground-giving act as the obtaining of a benefit from another's property or services, and its conditions as the combination of the absence of legal ground and the causing of damage. The provision designates that benefit as the object of restitution, but does not also record the expansion or restriction of the scope of restitution dealt with in the adjacent section.
The reason the absence of legal ground and the linkage of benefit and damage must be looked at together is that the requirements of the obligation to return are divided into two layers. The first layer screens whether the benefit obtained by the recipient came from another's property or services; the second layer screens whether that benefit was obtained without legal ground and thereby caused damage. In accordance with this distinction, the unjust enrichment confirmed in this section means a benefit obtained without legal ground from another's property or services and causing damage. The reason the difference in the aims of performance and damages, seen above, meshes with this distinction of layers is that the tasks must be viewed separately: restitution turns back the performance to be recovered, while damages fill the harm within the scope of liability. It is hasty to fix the scope of restitution when only one of the requirements has been confirmed.
So long as formal requirements such as a written contract or registration remain, a person who has in reality acquired another's property without any burden can appear as a recipient possessing a cause. If that form is strictly upheld, the result is an inconvenience whereby not all the benefit another obtained is returned, and the money that person spent remains as the other party's damage. However, the conclusion remains intact within the range that this objection cannot shake. The absence of legal ground cannot be confirmed by the existence of the benefit alone, and restitution must be determined after separately inquiring into the presence or absence of a formal cause. The justificatory possibility of form pointed out by the objection is not erased; it is only limited to the point that such form is merely material used in judging the absence of legal ground.
Returning to the synthetic scene, only a few facts touching this question are taken up. B received a performance from plaintiff A, and asserts having learned later that there was no ground for that payment. What has been confirmed up to this point is only B's receipt of the performance, the absence of a ground for payment, and the claim of subsequent recognition. Whether a formal cause existed, from what property or services the performance actually derived, and what damage A suffered as a result are not determined in this scene. Accordingly, on this scene alone one cannot adjudicate the effect of the non-existence of a debt, the attribution of the unlawful cause, or whether the benefit subsists, which the adjacent section addresses. The confirmed facts merely remain as candidates that can be tried against the definition of unjust enrichment.
What this section permits is going so far as to make the return of the other party's benefit a matter of question where that benefit was obtained without legal ground from another's property or services and is linked to damage. What this section does not permit is fixing the obligation to return and its scope on the single fact that a benefit has been confirmed. Beyond the judgment that unjust enrichment is established when the absence of legal ground and the linkage of benefit and damage from another's property or services appear together, the meaning of a formal cause or the consequences of the non-existence of a debt cannot be fixed in this section in its stead.
1.9Application of the Text of the Provisions and the Holdings of Precedents
The question at this stage is whether this assertion creates an obligation to return forthwith. The source text corresponding to this question is as follows. Civil Act Article 741 provides: "A person who, without any ground provided by law, has benefited from another person's property or labor and thereby caused loss to that person shall return such benefit." This wording points to three elements together. First, the person who obtained the benefit in a state without any ground provided by law is the party obliged to return it. Second, that benefit must derive from another person's property or labor. Third, that benefit must be connected as a result that caused loss to another person.
In this wording, the object of the return is 'that benefit.' The connection between the absence of any ground provided by law and the loss cannot be fixed as a single matter apart from the preceding conditions. The conditions for return are not satisfied merely upon confirmation that a benefit was obtained; whether a benefit obtained without loss, or a benefit unrelated to another person's property or labor, falls within the object of return under this wording remains to be determined separately. The basis of the determination is bound by the wording of this Article and is not extended to the reasons for the judgment or to other provisions.
This counterargument holds that, in formal terms, so long as a document or practice stating the cause of payment remains, a claim for restitution is blocked, and that in the meantime the beneficiary may spend another person's money and still escape liability. However, the absence of any ground provided by law and the benefit are separate elements, and the existence of a benefit alone cannot establish the absence of any ground provided by law. If a formal cause remains, whether that cause actually supports the performance is a matter to be judged by comparing the elements of the wording one by one, and the size of the benefit cannot substitute for the absence of a cause.
In this scene, the beneficiary B asserts having received the performance sent by plaintiff A and having learned later that there was no cause of payment. From this scene alone, the connection between the performance and the loss, the awareness at the time of payment, the point in time of the later awareness, and the scope of the remaining benefit are not confirmed together. The size of the remaining benefit or of the loss cannot be ascertained, as no amount is set in the scene. If it is confirmed that the illegal cause lay with the beneficiary alone, the comparative sentence stating that the exclusion of restitution on the sole ground of performance for an illegal cause is corrected is no more than a test that changes the conditions, and no such circumstances have actually been confirmed in this scene.
What this section permits is limited to judging the obligation to return by comparing the elements of the wording of the relevant source text together. To establish the absence of any ground provided by law from the mere existence of a benefit, or to fix the return while omitting the connection with the loss, exceeds the permitted conclusion. Circumstances that have not been ascertained remain undetermined, and the determination is made narrowly within the scope in which the elements of the wording are confirmed.
1.10Fine Distinctions Within the Stage
Even where restitution and compensation are written together under the same item, this is not treated as a ground permitting double recovery. Taking up this premise, the question at this stage is not whether restitution can be obtained whenever the other party has obtained a benefit, but rather, within the restitution of unjust enrichment and its scope, which part is to be divided again for determination.
The party designated by this wording is a person who has obtained a benefit from another person's property or labor, and the act is that of having caused loss to another person by obtaining that benefit. The conditions for restitution are that the absence of any ground provided by law and the connection between the benefit and the loss are established together, and the object to be returned is the benefit obtained.
Linking this basis with the present conclusion, the determination of restitution is bound to the stage in which the absence of a ground provided by law, the benefit arising from another person's property or labor, and the resulting loss all mesh together. Yet within that stage there remain parts to be divided again. There are cases where the connection between a groundless benefit and a loss is recognized, no restriction on restitution applies, and the scope is specified, such as good faith or bad faith and the existing benefit; and there are cases where payment was made knowing that no obligation existed, or where the restriction on restitution of performance for an illegal cause applies and no statutory exception exists. The reason for separating the two distinctions is that the former is a determination that opens the channel of restitution while the latter is one that closes it, and beyond this, if the cause of payment, the beneficiary's knowledge, or the remaining benefit cannot be confirmed, the matter remains undetermined. This distinction is limited to the stated conditions and creates no further stage.
The counterargument that a formal cause can justify an unjust benefit is directed at the loss and inconvenience arising if, by narrowing liability to the existing benefit, a person who has spent another person's money avoids restitution. Such criticism gains concrete force in scenes where a person who has already consumed another's property is exempted on the sole ground that no existing benefit remains. Yet against this counterargument too, an answer of the same scope is maintained. The separate inquiry into whether the formally attached cause departs from the actual relationship, and the scope inquiry into whether the benefit remains, occupy different positions, and one cannot substitute for the other.
From this fact alone, neither the content and amount of the performance, the awareness at the time of payment, the attribution of the illegal cause, nor the presence or absence of the remaining benefit is determined. The determination record takes as its columns the performance and the cause, the awareness at the time of payment, the attribution of the illegal cause, the existence of the benefit, and the later awareness, but what is confirmed at present is only the form of this assertion. Because the cause of payment, the beneficiary's knowledge, and the remaining benefit cannot be confirmed, this item remains undetermined. Only the condition that, if it is confirmed that the illegal cause lay with the beneficiary alone, the exclusion of restitution on the sole ground of performance for an illegal cause is corrected, is noted for comparison.
The conclusion permitted by this section is narrow. The detailed distinctions within the stage are limited to the stated conditions of cases that operate, cases that are blocked, and cases that are undetermined, and no circumstances beyond these may be raised as a new stage to fix or exclude restitution. An obligation to return does not arise merely from the fact that a benefit was obtained, nor is the presence or absence of a ground provided by law established merely by the fact that a formal cause is attached or that the benefit remains.
1.11Synthesis of Effectiveness, Blockage, and Undetermination
What the preceding stage confirmed is that restitution is directed at the performance to be recovered and compensation is directed at the loss within the scope of liability, and therefore the mere overlap of the same item is not itself a ground permitting double recovery. This question requires a separate determination of whether restitution itself is opened or blocked, and within what scope it is opened.
The relevant source text is Civil Act Article 741, whose wording provides: "A person who, without any ground provided by law, has benefited from another person's property or labor and thereby caused loss to that person shall return such benefit" (Civil Act Article 741). The party addressed by this wording is a person who has obtained a benefit from another person's property or labor; the act is the return by the person who obtained the benefit of that benefit; and the conditions are that the absence of any ground provided by law and the connection of the benefit with the loss are both satisfied. Here, the absence of any ground provided by law means a state in which the legal relationship that would serve as the ground for the transfer of the performance is lacking, and the connection with the loss means the relation by which that benefit derived from the other side's property or labor.
Only by reading the conditions of this wording together as one can it be determined whether the door of restitution is opened. Thus the single fact that a benefit was obtained is insufficient, and it must be confirmed together that the benefit arose without a cause, is connected with a loss, and does not fall under any restriction on restitution. In the same vein, the undetermined state must be kept separate. Where the cause of payment, the beneficiary's knowledge, or the remaining benefit cannot be confirmed, it is not fixed as either open or closed, but is left as a case in which the determination may vary according to the conditions that are confirmed.
The strongest counterargument is directed at the point that a formal cause can justify an unjust benefit. This counterargument points out that narrowing liability to the existing benefit produces the disadvantage that a person who has spent another person's money avoids restitution. That point has a valid aspect. If the person who actually spent the money escapes on the sole ground that no benefit remains, the party who suffered the loss bears it as it stands. Even so, the existence of a benefit alone cannot establish the absence of any ground provided by law, and therefore the absence of any ground provided by law must be confirmed separately from the benefit.
In this scene, the items to be confirmed are that there was a performance and that there was no cause of payment, as well as the later awareness asserted. However, whether beneficiary B knew of the absence of a cause at the time of payment, whether the benefit received still remains, and whether there truly was no cause of payment at all cannot be confirmed from the scene alone. Accordingly, the determination in this section can distinguish openness from blockage only after comparing the records of the performance and the cause, the awareness at the time of payment, the existence of the benefit, and the later awareness.
The conclusion permitted by this section is the path of restitution where the conditions are satisfied; the conclusion not permitted is the path of restitution that declares the absence of a cause from the benefit alone. Where payment was made knowing that no obligation existed, or where the restriction on restitution of performance for an illegal cause applies and no statutory exception exists, the path is blocked; and where the cause of payment, the beneficiary's knowledge, or the remaining benefit cannot be confirmed, the matter is left undetermined.
1.12Conclusion Carried Over to the Next Section
Unjust enrichment means a benefit obtained from another person's property or labor without any ground provided by law and causing loss, yet the very fact that a benefit was obtained does not itself mean an obligation to return. The preceding section concluded as follows: where the connection between a groundless benefit and a loss is recognized, no restriction on restitution applies, and the scope is specified, such as good faith or bad faith and the existing benefit, the rule operates; where payment was made knowing that no obligation existed, or where the restriction on restitution of performance for an illegal cause applies and no statutory exception exists, it is blocked; and where the cause of payment or the beneficiary's knowledge and the remaining benefit cannot be confirmed, the matter remains undetermined. Before answering the question whether restitution can be obtained whenever the other party has obtained a benefit, what remains is what the conclusion of this section hands on to the next question.
This wording requires together the absence of any ground provided by law, the benefit arising from another person's property or labor, and the resulting loss. The party said to bear the obligation to return is the person who obtained the benefit; the object is the benefit that person obtained; and the presupposed act is the use of another person's property or labor. However, since this wording also places alongside it the connection requiring that there be a loss, it is difficult to read it as making anyone an object of return on the single fact that a benefit was obtained.
Accordingly, the answer preceding this question is that the absence of any ground provided by law and the connection of the benefit arising from another person's property or labor with the loss must be viewed together. Here, the absence of any ground provided by law and the connection between the benefit and the loss enter into different stages of determination. The former asks whether there was a juristic act or other cause serving as the ground of the performance; the latter asks whether the benefit obtained derived from another person's property or labor and whether loss thereby arose on the other side. The reason for viewing the two separately is that the absence of a cause cannot be inferred from the mere existence of a benefit, and that even where the absence of a cause has been established, a benefit unconnected with a loss differs from the return contemplated by this Article.
The counterargument that a formal cause can justify an unjust benefit is directed at the loss and inconvenience arising where, once a documentary basis is attached, that benefit is treated as having a ground provided by law and the claim for restitution is blocked. The concern that a person who has spent another person's money will avoid restitution points in the same direction. Yet if the counterargument were accepted and the absence of any ground provided by law established from the mere existence of a benefit, restitution would be allowed without inquiring whether an actual cause existed, and this would exceed the boundary. The preceding answer is that the existence of a benefit alone cannot establish the absence of any ground provided by law, and even where a formal cause is at issue, the response is to confirm the absence of a cause and the connection between the benefit and the loss separately.
What is confirmed in this scene is that there was a performance, that beneficiary B obtained a benefit thereby, and that B asserts having learned of the absence of the cause of payment afterwards. That there was no cause of payment is only B's assertion, and the time at which B became aware is likewise merely asserted; therefore, from the scene alone it cannot be categorically affirmed that the absence of any ground provided by law and the connection with the loss have been established. The determination turns on which of the items among the performance and the cause, the awareness at the time of payment, the attribution of the illegal cause, the existence of the benefit, and the later awareness has been established. The parts not confirmed remain undetermined.
The conclusion permitted by this section is that the mere fact that the other party obtained a benefit cannot yield an obligation to return, and that the absence of any ground provided by law and the connection of the benefit arising from another person's property or labor with the loss must be confirmed together. What this section does not permit is ordering restitution by establishing the absence of any ground provided by law from the mere existence of a benefit, nor does it permit blocking restitution on the sole ground of a formal cause. The connection between the benefit and the loss, the absence of a cause, and the restrictions on restitution must each be confirmed separately, and none of them substitutes for another by having been established earlier.
