But, my Lords, I contend that this witness is inadmissible from the particular circumstances attending his case. For, according to the information which I have received, when this witness was apprehended and committed to prison, in the month of March last, to stand trial for this crime, he never charged Mr. Brodie as having been in any measure accessory thereto. On Ainslie’s first examination he positively affirmed that Mr. Brodie had no sort of accession to the crime of which he is now accused, or was concerned in any other bad action whatever to his knowledge, unless playing at cards and dice should be reckoned such; and in the different declarations which he made before the Sheriff he still persisted in denying that my client had any concern in this robbery. But after Mr. Brodie was apprehended and brought from Holland Ainslie was again brought before the Sheriff, when he was informed that either he himself must be hanged or he must accuse Mr. Brodie. Further, I am now instructed to say that when this witness was carried before the Sheriff his life was offered to him on his becoming King’s evidence against Mr. Brodie, and accusing him of having been concerned in this robbery, and that, even notwithstanding this offer, he persisted in denying that Mr. Brodie was guilty of this crime, until John Brown alias Humphry Moore, another of the witnesses cited, and alleged also to have been a socius criminis, was allowed to see and converse with him in prison, when at length he came into the measures proposed. I mean to say nothing against the conduct of the Sheriff, which may have been very proper—with the motives which may have influenced a public officer to a particular line of conduct I have nothing to do—but I state it as an insuperable bar to the admissibility of this witness, that hopes were suggested to him of saving his own life by criminating my client. And I offer to prove, by the evidence of the Sheriff of Edinburgh himself, that a bargain of this nature was made with Ainslie, and that it was not till then he was prevailed upon to say that Mr. Brodie had any concern in this crime. No man could withstand such a temptation, and it is impossible that the Court can receive the testimony of a witness in such circumstances.
The Lord Advocate—My Lords, I hardly expected that such an objection would have been made at this time, as it has long been the universal practice to admit socii criminis as evidence, and at the last trial in this Court such a witness was received without even an objection being stated. All the arguments on the other side could only affect the credibility of the witness, which properly belongs to the jury, and not the admissibility, which alone is before the Court. It is indeed true, and I am even surprised that the honourable counsel had not appealed to the authority, that Sir George Mackenzie has laid it down that socii criminis could not be admitted as evidence; but upon what principle of law or reason Sir George formed that opinion I could never discover. Sir George Mackenzie, indeed, is an author by whom I never was much instructed. He is often contradictory, always perplexed, and in many instances unintelligible. But even supposing the law had so stood in his time, the Court and the practice have long since deviated from it.
My Lords, the fact as stated by the Dean of Faculty is

erroneous in every respect. For although Ainslie in his first declaration did not accuse Brodie or any other person, and denied all knowledge of the crime, yet in the second declaration which he emitted before the Sheriff on the 14th of March, which I now hold in my hand, and would read did the forms of the Court permit me to do so, he in the most express terms charges both Brodie and Smith as being equally concerned in the crime libelled. And, my Lords, it will not easily be believed—indeed, the thing is incredible—that so respectable an officer of the law as the Sheriff of Edinburgh would ever have entered into such stipulations with Ainslie. But even had such transaction taken place before any inferior judge or magistrate, still that cannot deprive the public prosecutor of the evidence of this witness, for it will not be said that any such transaction passed between him and the witness, and therefore the objection ought to be repelled, reserving the credibility of his evidence to the jury.
The Dean of Faculty—My Lords, I offer to prove my assertion.
The Lord Advocate—My Lords, I am willing, if the Dean of Faculty and the Court consent to it, to hold the second declaration, emitted long before Mr. Brodie was apprehended, as the evidence to be delivered by Ainslie on this occasion.
Lord Eskgrove—No transaction of any kind can possibly take place where life and death are concerned; and, therefore, even although the counsel on the other side consent to such a proposal, the Court would not allow it.
The Lord Justice-Clerk—Dean of Faculty, do you say that my Lord Advocate has made a corrupt bargain with the witness to accuse Mr. Brodie upon condition of receiving a pardon?
