The senate of the state was engaged in an investigation of the conduct of its members un-' der a published charge that some of them, whose names were not given, had taken bribes for aiding in the pas*299sage of a certain bill. The news editor and one of the reporters of the paper which published this charge were called upon to testify in the matter, and refused to answer certain interrogatories propounded to them, upon the ground that the information sought to be elicited was privileged, and that the evidence, if given, would be irrelevant and hearsay. The questions contained a demand that the witnesses should give the names of those from whom they had received information touching the charge of bribery, and the nature of that information. The inquisitorial investigation upon which the senate was engaged was one strictly within its jurisdiction to prosecute. It had the undoubted power to examine into the alleged criminal conduct of some of its members, with a view to their expulsion or other punishment if found guilty. (Ex parte McCarthy, 29 Cal. 395.) Under such an investigation, these witnesses, who were shown to have been responsible for the published charge, and who at the same time disclaimed personal knowledge of the facts, were asked to give the names of their informants. It was a natural and logical method for the senate to follow in its endeavor to arrive at the truth. If the witnesses, first answering that they had no personal knowledge of the matter, were to be justified in refusing to give the names of their informants, the senatorial inquiry must necessarily come to an end. Upon the other hand, if they stated the names of their informants and the nature of their information, the senate could summon those persons and so trace the charge to a just conclusion. The evidence, then, was relevant and pertinent. The case differs from those presented in courts where the interests lie between conflicting parties, and where improper evidence sought to be introduced in the interests of one must be to the injury of the other. Here the inquiry was inquisitorial, to arrive at the truth concerning a public charge of corruption, silent as to names, indefinite as to facts, but specific in its assertion of bribery. There were no parties to this proceeding. The senate was investigating the conduct of its own *300members, and it was a contempt of its authority for the witnesses to refuse to give the names of those who were responsible for the promulgation of the charge. It cannot be successfully contended, and has not been seriously argued, that the witnesses were justified in refusing to give these names upon the ground that the communications were privileged.
