2 Examination in initialibus may be dispensed with.
It shall not be necessary for any judge in Scotland, or for any person acting as commissioner in taking evidence in any action, cause, prosecution, or other judicial proceeding, civil or criminal, depending in Scotland, to examine any witness in initialibus: Provided always, that it shall nevertheless be competent for any such judge or person acting as commissioner, or the party against whom the witness shall be called, to examine any witness in initialibus as heretofore.

3 Presence in court not to disqualify witnesses in certain cases.
In any trial before any judge of the Court of Session or Court of Justiciary, or before any sheriff principal in Scotland, it shall not be imperative on the court to reject any witness against whom it is objected that he or she has, without the permission of the court, and without the consent of the party objecting, been present in court during all or any part of the proceedings; but it shall be competent for the court, in its discretion, to admit the witness, where it shall appear to the court that the presence of the witness was not the consequence of culpable negligence or criminal intent, and that the witness has not been unduly instructed or influenced by what took place during his or her presence, or that injustice will not be done by his or her examination.
