The defendant, Murphy, called as a witness by the plaintiffs, testified that he represented the other defendants after the strike and was inquired of as to statements made by him as to the object of the strike both during a conference between the parties before the labor commissioner and at other times. To the ruling requiring the witness to answer, the defendants excepted. Murphy, though a party, was a competent witness and could be required to testify. Whitcher v. Davis, 70 N. H. 237. He could not of course be required to give testimony tending to incriminate himself, to detail an offer of compromise or disclose privileged communications. But it does not appear that the questions asked him had such tendency. There is no evidence of an offer of compromise by either party. If there had been, an admission of an independent fact hke that inquired about, the object of the strike, would be competent. Colburn v. Groton, 66 N. H. 151, 156. The defendants contend that as matter of public policy all communications to the labor commissioner should be privileged. This is matter for the legislature. The statutes on the subject in force at the time contain no such provision but on the other hand indicate a legislative belief that the public good demands publicity rather than secrecy as to the controversies which the office was designed to adjust. Laws 1911, c. 198, ss. 3-8; Laws 1913, c. 186, ss. 3, 4.
Since the argument of this case the legislature has amended s. *401 4 of c. 198, Laws 1911, renumbered by s. 1, c. 186, Laws 1913, by adding at the close, “neither the proceedings nor any part thereof before the labor commissioner by virtue of this section shall be received in evidence for any purpose in any judicial proceeding before any other court or tribunal whatever.” This amendment was adopted April 10, 1917. Laws 1917, c. 142, s. 1. Section 4, referred to, prescribes the duty of the commissioner, “Whenever any controversy or difference arises relating to the conditions of employment or rates of wages between any employer . . . and his . . . employees.” Section 7 of the same act relates to his action when he has knowledge a strike is threatened or has occurred. Whether the matters inquired about arose in proceedings under section seven or section four; whether the amendment applies to proceedings under seven as well as under four and whether the amendment will be applicable in further proceedings in this suit, pending when the legislation was adopted (Rich v. Flanders, 39 N. H. 304; Kent v. Grant, 53 N. H. 576), are questions which were not presented when the case was argued and which therefore are not ndw considered.
The labor commissioner did not put his objection to testifying upon the ground that he was judge of a court but upon the ground that the communications made to him were privileged. If the witness was a judge called to testify as to proceedings before him that fact did not render his testimony incompetent, Hale v. Wyatt, 78 N. H. 214, and as the court had already ruled the matter inquired about was not privileged the defendants’ objection to the questions should have been overruled. The court suggested that, if the commissioner objected, he could not be compelled to testify because he was a quasi judicial officer. This suggestion was made in reliance upon the decision in Hale v. Wyatt, supra. The office of labor commissioner was created in 1893. The duties of the office as then defined were “to collect, assort, arrange, and present in annual reports . . . statistical details relating to all departments of labor in the state.” Laws 1893, c. 48, s. 5. By the legislation of 1911 additional duties of investigation, prosecution, advice and persuasion and report are imposed upon the commissioner. He is not to hear and decide controversies between employers and employees but to endeavor to bring about an amicable adjustment, and, failing that, to induce the parties to submit the dispute to arbitrators or to the state board of conciliation and arbitration substituted two years later for the board of arbitrators. In case of failure to *402 secure such reference in case of a strike, he is to investigate the causes of the controversy, ascertain which party is mainly responsible and make and publish a report assigning such responsibility. But there is no suggestion such investigation is to be a judicial one. No machinery is provided for a judicial proceeding. The only trace of judicial action is found in the provisions of section 3 requiring him to hear all parties and advise them in certain circumstances what, if anything, ought to be conceded by either or both. Laws 1911, c. 198, s. 3; Laws 1913, c. 186, s. 1. While it may well be that the duty of conciliation imposed upon the commissioner can be better performed, as the legislature now seem to think, if some or all communications to or before him are held privileged, the commissioner cannot claim the privilege of exemption as a witness in view of the numerous other duties imposed on him, unless at the time about which inquiry is sought of him, he was engaged in a purely judicial duty. It does not appear that the information sought of him in the present case was obtained by him while acting in such a. capacity, and it is clear that judicial power which would excuse him from appearing as a witness has not been given to him.
In
Hale
v.
Wyatt,
78 N. H. 214, the judge of probate was called and testified upon appeal as to statements made in a hearing before him. The question was as to the competency of the evidence, which was decided in the affirmative. What circumstances would justify a judge in refusing to testify to matters which occurred at a trial before him, there was no occasion to discuss. The point was not presented. “A
judge
of a superior court seems to have been regarded as exempt from attendance at common law.” 4 Wig. Ev., s. 2372 (3). While it is stated generally in the text books and in some cases that a judge of a court of record cannot be required to testify as to matters occurring before him in court (1 Gr. Ev. (16th ed.) s. 254(c),

v.
Batchelder,
Certain other questions were then mooted, bearing upon the maintenance of the proceeding, upon which the court ruled subject to exception. These exceptions are also transferred with the suggestion that their determination in advance of a trial may shorten or avoid the hearing upon the facts. This procedure is one often employed when justice and convenience require, but it is not the practice to consider difficult questions of law which may not arise when the facts are found. Glover v. Baker, 76 N. H. 201, 203. Questions considered in this way are, ordinarily, important ones necessarily involved in the action. Hampton Beach Co. v. Hampton, 77 N. H. 373. It is not the duty of the court under the guise of this procedure to advise the parties in advance as to their rights under all possible facts which might be proved. As suggested, the allega *404 tions of the bill seem to be regarded as sufficient while the requests to rule amount to an inquiry whether the plaintiffs may not recover upon proof of much less than they have-alleged. In this-situation the views of the court are properly expressed only upon the precise questions raised by exception. Two questions were raised.
1. The court was asked to rule that if the defendants combined to bring about a strike in the plaintiffs’ shops and the strike was accordingly inaugurated for the object of thereby compelling the plaintiffs to employ only union men, such action would constitute a conspiracy as matter of law. The court declined to so rule and the plaintiffs excepted. The court then stated that he could not find from these facts that the defendants’ conduct was unreasonable. It does not appear whether this statement was intended as a finding of fact or as a ruling of law. No exception is reported and no question is transferred upon this statement. The plaintiffs’ present contention is that a combination for the purpose of compelling them to employ only union men in their shops is unlawful and constitutes a conspiracy as matter of law. This appears to be the first controversy of this character in this jurisdiction, but the defendants claim that
Huskie
v.
Griffin,
75 N. H. 345, is decisive of the question now under consideration. There was no question of combination in
Hushie
v.
Griffin.
The acts of a single individual were under consideration. But an act unlawful for one to do is not made lawful because done by a combination. If the defendants have undertaken by combination or otherwise to compel the plaintiffs to employ only certain individuals or a certain class in their shops, they have interfered with a right of the plaintiffs, said in
Hushie
v.
Griffin
to be "inherent in the idea of Anglo-Saxon liberty,” the right to freely •deal or refuse to deal .with others;
“prima facie
a man can demand an open market.”
Huskie
v.
Griffin, supra, pp.
347, 350. The •defendants concede the interference; they say in their brief: “a strike to enforce a ‘closed shop’ may be unlawful, and it may be lawful. ... A strike to enforce a closed shop is unlawful unless there is justification.” This is the -view of
Hushie
v.
Griffin, supra,
quoting from
Parkinson Co.
v.
Trades Council,
2. The second question raised relates to the conduct of the strike. The plaintiffs’ counsel asked the court to rule that all organized picketing is unlawful. The court declined to so rule, but did rule that reasonable picketing was lawful; unreasonable, unlawful; and the plaintiffs excepted. The term picketing is new in the law of the state. The only definition in the case is “picketing . . . *406 by twos, who parade the streets, observe who are entering and leaving the plaintiffs’ shops in order that they may argue and persuade them to join the strike.” The allegations of the bill lead to the inference that picketing may mean something more than peaceful parading, whatever that may mean. The dictionary defines picketing as “to post watchers at the approaches to a place of employment affected by a strike in order to ascertain those who work there and persuade them, or otherwise influence them, to give up the work.” Webst. Dict. Picket; R. & L. Law Dict. Picketing. The cases cited in the notes, 4 L. R. A. (n. s.) 302 and 50 L. R. A. (n. s.) 412, indicate that the term may include a wide range of action. The material question is whether the acts done in prosecution of the strike are lawful or unlawful, whether, properly described as picketing or by some other term.' ‘ Although the term is not found in the law of the state, Public Statutes, c. 266, s. 12, as amended by c. 211, Laws 1913, and P. S., c. 264, ss. 1, 2, maybe aimed at some acts included within the term or naturally resulting from the proceeding so called. The substance of the court’s ruling was the application of the test of reasonable conduct under all the circumstances. Whether when the facts are found the acts of which' the plaintiffs complain can be found to be reasonable in fact cannot be determined until the facts are found. If one may interfere with another’s lawful business when it is a reasonable thing to do, it follows that he may do so in a manner not unreasonable in fact or because forbidden by legislative mandate.
Case discharged.
