Opinion by
Mr. Justice Mestrezat,We do not agree with the learned court below that the affidavit sets up a prima facie defense in averring that by virtue of certain acts of assembly of the state of New York and their construction by the courts of that state the contract of the parties “was unlawful and void in that it was an agreement to perform in the state of New York any opera, or any parts of opera, or other dramatic performance, upon the first day of the week, commonly called Sunday, in violation of said statutes.” A copy of the contract on which the suit was brought is attached to and made part of the statement. It was executed in New York and provides, inter alia, as follows: “The artist (Giovanni Zenatello) binds himself to sing in his capacity *58of tenor, and shall sing in Italian, in New York and in the United States of America, the operas of his repertory and those which will be indicated to him .... Mr. Oscar Hammerstein (the defendant) binds himself to pay the artist the sum of 1300 American Dollars for each performance or Sunday concert, which sum shall be paid to the artist the day after the performance.” For present purposes we may assume, as defendant alleges, that the statutes of New York make it unlawful to perform in the state of New York any opera or other dramatic performance on Sunday, and that an agreement is void which stipulates for such performances on Sunday in New York. The contract between the plaintiff and the defendant and on which this action was brought, however, does not provide that the plaintiff shall sing only in New York, as assumed by the learned court below, but “in New York and in the United States of America.” Zenatello was to sing each day of the week. The agreement, therefore, does not provide that he shall sing in New York on Sunday, and the presumption is that Hammerstein will not require him to sing in that state on Sunday but in some other part of the United States where Sunday concerts are not prohibited. The law will not presume that the parties contracted to do an unlawful thing or violate a statutory prohibition in carrying out its terms, but that their purpose was the accomplishment of a lawful object and the performance of the agreement in a place or territory where its performance was permissible. We must, therefore, construe this agreement to mean' that the parties intended that the plaintiff should sing his operas in those parts of the United States where such performances would be legal and not in the state of New York where they are prohibited. It is settled law that the validity of a contract as to matters affecting its performance is to be determined by the laws of the place of performance and not the place of execution. The laws of the state of New York, therefore, have no application in construing the contract in question and, hence, the averment in the affidavit *59that the contract is void under the New York statutes is not a defense to this action.
The statement avers that the plaintiff was ready and willing at all times and offered to perform his engagements under the contract. This is denied by the affidavit of defense, and it is averred that after the fourteen performances, the “defendant desired and requested plaintiff to sing the tenor part in the opera 'The Prophet/ which was a part the plaintiff was well fitted to sing, but said plaintiff, without reason or excuse, declined and refused to sing the part.” The contract bound the plaintiff to sing “the operas of his repertory and those which will be indicated to him.” Another part of the contract specifies the operas of the plaintiff’s repertory and provides that he shall sing those operas, “and some other operas which may be indicated, so long as they are fit for him, and they are arranged on mutual agreement.” The plaintiff contends that he was justified in refusing to sing the tenor part in “The Prophet” as it was not one of those specified as part of his repertory and was not agreed upon by mutual consent between the parties. This question was clearly for the jury under proper instructions by the court. We must assume the truth of the averment in the affidavit that the defendant requested the plaintiff to sing in “The Prophet,” that he was fitted to sing in it, and that he, “without reason or excuse, declined and refused to sing the part.” If this be true, the plaintiff violated his contract. He was, by the terms of the agreement, to sing such operas outside of those specified in his repertory as the defendant “indicated to him,” and were “fit for him” when they were “arranged on mutual agreement.” It was, therefore, the duty of the plaintiff to sing the tenor part in “The Prophet” when requested by defendant unless he had a sufficient legal reason for refusing to do so, and whether he did so “without reason or excuse,” as averred in the affidavit, is necessarily for the jury. Being fitted to sing in the opera and being requested to do so by the defendant, the plaintiff could not arbitrarily decline to *60enter into a “mutual agreement” to sing “The Prophet.” These averments necessarily raise questions of fact for the consideration and determination of the jury.
We need not determine the questions of law suggested in argument other than those necessary to the disposition of this rule, as they can be better considered and decided in the light of all the facts developed on the trial of the cause before a jury.
The order discharging the rule for judgment for want of a sufficient affidavit of defense is affirmed.
