Use of Affidavits of Witnesses and Expert Reports at Trial
(7)A party who requires the attendance at trial of the deponent of an affidavit of witness or an expert shall, within 30 days after the expiration of the period referred to in paragraph (5), serve on every other party a Notice Requiring Attendance (Form 79B). Any such attendance shall be at the expense of the party requiring such attendance. If no Notice Requiring Attendance is served, the admissible parts of the affidavit of witness or expert report, as the case may be, shall be received in evidence at the trial without the need to call the deponent or the expert and without proof of signature or qualifications of the expert.
