law every court having the power to hear and determine any suit had the inherent power to call for all adequate proofs of the facts in controversy, and to that end to summon and compel the attendance of witnesses, and if the witness was expected to produce any books or papers in his possession a clause to that effect was inserted in the writ, which was then termed a “subpoena duces tecum.” 1 Greenl. Ev. § 309; 3 Bl. Comm. 382. The writ was of compulsory obligation. Amey v. Long, 9 East, 473. The controversy in this case is not, however, with respect to the power of the court to issue a subpoena duces tecum in a proper case, but it is contended that telegraphic communications are confidential, so far as the telegraph companies are concerned, and therefore, in their hands, such messages are in the nature of privileged communications, which it is the policy of the law to protect and keep inviolate. Judge Cooley, in his work on Constitutional Limitations, adds a note on page 327 (of the second edition), in which he takes this view. In the American Law Register for February, 1879, there is also an article by the same author entitled “Inviolability of Telegraphic Communications,” in which the whole subject is ably discussed, and his conclusions summed up in favor of the privileged character of these communications, based upon the principles of law declared in Entinck v. Carrington, 19 State Tr. 1030, and Wilkes v. Wood, Id. 1154, and upon our own constitutional provisions for the protection of private papers and personal rights. But the courts have certainly not adopted this view of the law, and legislation has not been in that direction. It is to be observed that no claim is made here that these telegrams are to be used in evidence .in any prosecutions against the telegraph company, or any of its officers. It is apparently conceded that the grand jury is investigating the conduct of the parties who sent or received the telegrams, and not the relation of the telegraph company to the alleged violations of law involved in the act of transmitting the telegrams between the parties. The case is not, therefore, within the liberal construction of the constitutional provisions in favor of defendants, as declared by the supreme court in Boyd v. U. S., 116 U. S. 616, 6 Sup. Ct. 524. There is no statute law of the United States making telegraphic messages, as such, privileged communications; and, if we assume that under section 858 of the Revised Statutes of the United States the law of this-state establishes the rule of decisions in this case, we find that it does not give to them‘that character, but, on the contrary, provides specifically that they may be disclosed by the lawful order of a court. Section 619 of the Penal Code of palifornia, as amended in 1880, provides as follows:
“Every person who willfully discloses the contents of a telegraphic message, or any part thereof, addressed to another person, without the permission of such person, unless directed so to do by the lawful order of a court, is punishable,” etc.
The article of Mr. Henry Hitchcock in the Southern Law Review (volume 5, N. S. 473), to which reference tyas made in the argument, reviews the provisions of law on this subject as judicially determined in the several states; and Mr. Ordronaux, in his Avork on
