The privilege of a witness, in not being compellable to answer any questions that may tend to criminate himself, is unquestioned, and was so held by the presiding judge. The only question raised upon this bill of exceptions is, whether the defendant had a right to interpose the objection, and require the judge to state the rule of law on the subject, independent of any objection taken by the witness himself. Upon this point the law is very well settled, that the privilege of declining to answer questions propounded to a witness, on the ground that the answer will have a ten dency to expose him to personal liability, or to punishment on any criminal charge, is the privilege of the witness, and not of the party against whom he is called to testify. 1 Greenl. Ev. § 451; Thomas v. Newton, 1 M. & Mal. 48, note; Rex v. Adey, 1 M. & Rob. 94. The case of Commonwealth v. Kimball, 24 Pick. 366, 369, is not in conflict with the principle of law above stated. The court, in giving their opinion in that case, very distinctly assume as a part of the facts in the case, that the objection was taken originally by the witness, and not by the party on trial. A further opinion held in that case was, that if the witness does thus claim his privilege, but the. court improperly deny the same, and require the witness to answer, exceptions to such ruling of the court *596may properly be taken by the party on trial. The principle there stated went no further than this, that where the privilege was seasonably claimed by the proper party, and not allowed, the verdict was not obtained upon legal evidence, and therefore might be set aside. It would seem also to be the only mode practicable for revising such decision, thus to present the question upon a bill of exceptions taken by the defendants. The case of the Commonwealth v. Kimball, however, really required no adjudication upon this point, as the court held, that there was no legal ground for any objections to the ruling of the court of common pleas, the answer of the witness having no tendency to criminate himself. Upon the question now presented, the court are of opinion that there is no ground for sustaining the exceptions.
