The Dean of Faculty argued this objection with great ingenuity, but he founded his whole argument on the proposition that an _infamia facti_, if it was capable of proof, was a sufficient objection to the admissibility of a witness; and, indeed, unless this proposition were true, his whole argument falls to the ground. But, my Lords, this proposition is evidently fallacious, and I need use no other instance than that of Ainslie, who, like every other King’s evidence, admitted in the very bosom of his deposition an _infamia facti_, in so far as he was concerned in the commission of the crime charged against the pannels, and yet it was not even pretended that this was an objection to his admissibility; and your Lordships every day allow the examination of witnesses in the same situation. I am therefore clear for repelling the objection. The Court then pronounced the following interlocutor:-- The Lord Justice-Clerk and Lords Commissioners of Justiciary having considered the foregoing objections with the answers thereto, they repel the objections stated and allow the witness to be examined, reserving the credibility of his evidence to the jury. ROBT. M‘QUEEN, I.P.D. [The witness was then called in and sworn.] The LORD JUSTICE-CLERK--John Brown, you are called here to give evidence regarding a matter in which it is generally supposed that you yourself had some concern. You are now informed by the Court that although you may have had such a concern you are in no danger to speak the truth, because, being adduced as a witness against the prisoners at the bar, you cannot be tried for the crime of which they are accused; and you will take notice that whatever you may have said against these men, in the different declarations which you emitted before the Sheriff, which are now destroyed, you are now bound by the great oath which you have sworn to tell the truth; and that if you say anything to the prejudice of these men that is not true or if you conceal any part of the truth, with a view to favour them, you will thereby be guilty of the crime of perjury, for which you will be liable to be tried by this Court, and severely punished, and you will commit a heinous offence in the sight of the Almighty God, and thereby endanger your immortal soul.
