Latin. For the purpose of easing or disburdening the conscience. Confessions so made, when proved, are conclusive against the person confessing, in regard to the subject matter of the confession. It sometimes happens that such confessions are made by criminals on their apprehension, and if so, they may be adduced in support of the prosecution against them. But if a person charged with a certain crime has been apprehended on that charge, and in answer to certain questions put by the apprehending officer, admits or confesses to certain points material to the prosecution, the substance of the prisoner's answers cannot be received as evidence against him. It is ultra vires of the officer to interrogate the prisoner; this can only be done by the proper authority, in the presence of a magistrate, whose duty it is to warn the prisoner that any statement he makes may be used against him, and to see any such statement, when made, fairly taken down. This is an established rule. See the Scottish law cases of Hay, 8th October 1858, 3 Irvine 181; and Millar. 2d April 1859, 3 Irvine 406.
