When a person at a hearing is questioned about a past fact learned through special knowledge, which rules govern that questioning instead of the rules on expert appraisal?
General information · Not legal advice
Material to check
The practice file to read is the court's list of witnesses and expert witnesses, the trial transcript showing what was actually asked of the person, and the paper describing the special knowledge on which the account rests. The transcript matters most, because the provision turns on the subject of the questioning: a past fact learned through special knowledge, not the label the file gives the person.
These are types of material to look for, not evidence already verified by PRO SE.
Where readings differ
One reading takes the provision as a switch of rules: where the questioning concerns a past fact that the person came to know through special knowledge, the examination is conducted under the provisions on witnesses and not under the provisions on expert appraisal, so the witness chapter's duties govern how the person is examined.
Another reading puts the weight on what is asked rather than on how the file lists the person: the provision names a past fact known through special knowledge as the trigger, and says nothing about opinions or appraisals offered for the court, so questioning that leaves that subject may still fall under this chapter's rules.
Your judgment
When the same answer mixes a past fact learned through special knowledge with an appraisal opinion, how should the questioning be separated so it is clear which rules apply?
PRO SE does not make this decision or keep a case record on this public site.When to reconsider
We look at this again if the provision is amended to change the subject matter that triggers the witness provisions, or if a court decision explains how far the witness chapter's duties carry over to such a person.
