264. A party may give another party a formal notice to admit the origin of a document or the integrity of the information it contains.
The formal notice must be notified at least 30 days before the trial. If the document or other evidence has not already been disclosed, a suitable representation of it or, in the absence of such a representation, particulars on how to access it must be attached.
The party having been given the formal notice admits or denies the origin or integrity of the evidence in an affidavit giving reasons, and notifies the affidavit to the other party within 10 days.
Failure to respond to the formal notice is deemed an admission of the origin and integrity of the evidence, but not of the truth of its contents.
