For here is a species of testimony invited, which is hitherto unknown to our law, and from which it may be difficult to tell who can be secure; the witnesses are required to disclose all matters relating to the conduct of _lord ORFORD, according to the best of their knowledge, remembrance, or belief!_ A form of deposition, my lords, of great latitude; a man's belief may be influenced by the report of others who may deceive him, by his observation of circumstances, either remote in themselves, or imperfectly discovered, or by his own reasonings, which must be just or fallacious according to his abilities; but which must yet have the same effect upon his belief, which they will influence, not in proportion to their real strength, but to the confidence placed in them by himself. There is only one case, my lords, in which, by the common course of proceedings, any regard is had to mere belief; and this evidence is only accepted on that occasion, because no other can possibly be obtained. When any claim is to be determined by written evidences, of which, in order to prove their validity, it is necessary to inquire by whom they were drawn or signed; those who are acquainted with the writing of a dead person, are admitted to deliver, upon oath, their _belief_ that the writing ascribed to him, was or was not his; but such secondary witnesses are never called, when the person can be produced whose hand is to be proved. There is yet another reason for which it is improper to admit such evidence as this bill has a tendency to promote. It is well known, that in all the courts of common law, the person accused is in some degree secured from the danger of being overborne by false accusations, by the penalty which may be inflicted upon witnesses discovered to be perjured; but in the method of examination now proposed, a method unknown to the constitution, no such security can be obtained, for there is no provision made by the laws for the punishment of a man who shall give false evidence before a committee of the house of commons.
