Following the entry of an interlocutory decree sustaining the defendants’ demurrer to the plaintiff’s bill, the judge reported the matter to this court. G. L. c. 214, § 30.
The pertinent averments of the bill are these. The plaintiff, United Kosher Butchers Association (United), is a Massachusetts corporation, whose “members” consist of most of the kosher retail meat stores in Greater Boston. Since 1930 United has been actively engaged in the certification and supervision, under rabbinical auspices and direction, of its member stores with respect to kosher meats and poultry. The member stores hold themselves out to the public as handling these items. For the past seven years United’s activities have been conducted under the direction of Rabbi Mordecai Savitsky. Through his efforts and in accordance with his interpretations United has enforced strict compliance with the tenets of the orthodox Jewish faith. By reason of the high standing in the community of both United and Rabbi Savitsky the consumer public desiring to purchase kosher meats and poultry has accepted United’s certification “in complete faith and assurance that all the Kashruth requirements have been thoroughly observed. ’ ’ All of the member stores by virtue of their membership are “under contract . . . with . . . [United] to *597 comply with all the requirements and standards of . . . [United’s] Rabbinical Advisor.’’
The defendant, Associated Synagogues of Greater Boston, Inc. (Associated), is a Massachusetts corporation which maintains a committee known as the “Kashruth Commission.” With the aid of the “Yaad Harabonim of Greater Boston” (a group of orthodox Jewish rabbis), the “Kash-ruth Commission” certifies caterers in Greater Boston as authentic purveyors of kosher foods. For “many years” United’s certification of kosher food and meats had been accepted by Associated in approving caterers. However, since August 15,1960, Associated has refused to accept the “Rabbinical certification” of Rabbi Savitsky and has required that kosher caterers “purchase meat from kosher retail meat stores supervised by the Yaad Harabonim.” United’s member stores have been notified that their meat and poultry orders to kosher caterers will not be acceptable unless their preparation has been supervised by Associated’s rabbinical inspectors. As a result of this notification numerous orders from kosher caterers to United’s member stores were cancelled. The plaintiff charges that by virtue of these activities the defendants are “guilty of a Restraint of Trade, elimination of a free market and the hindering and denying of free competition.”
The bill further recites that throughout this same period the several defendants have solicited various member stores to end their relationship with United and to accept the rabbinical supervision of the “Yaad Harabonim.” The defendants were notified in August, 1960, that this line of conduct had already resulted in several breaches of existing agreements between the plaintiff association and its members. At no time during this controversy, however, have the defendants complained to the plaintiff’s rabbinical ad-visor of any known or suspected irregularities or departures from strict Kashruth requirements in the performance of his duties. These actions, it is charged, illegally interfere with United’s contractual relations.
The plaintiff seeks to have the defendants enjoined from *598 engaging in the activities complained of in the bill; and there is also a prayer for damages.
The sole basis of the demurrer is that the bill pertains to matters which are exclusively ecclesiastical under the orthodox Jewish religion and hence are not proper subjects for judicial inquiry.
It is settled by our decisions that courts will not interfere in a controversy which is exclusively or primarily of an ecclesiastical nature.
Fitzgerald
v.
Robinson,
Phrasing the issue raised by the demurrer in terms of whether the controversy is “primarily” or “largely” a religious one can be misleading. The determination of a religious question by religious authorities may seriously affect the property or property rights of an individual. This was the case in
Grosvenor
v.
United Soc. of Believers,
In essence the plaintiff is asking that Associated and its allied groups be compelled to accept United’s guaranty that products prepared under its auspices are authentically kosher. This we decline to do. Aside from the constitutional freedoms involved, this court is not qualified to decide and therefore must refuse to consider an issue which is so exclusively one of religious practice and conscience. As was said by Rugg, C.J., in
Moustakis
v.
Hellenic Orthodox Soc. of Salem & Peabody,
Nor will the charge of restraint of trade render this dispute a proper subject for judicial determination. Foods labeled kosher have a deeply religious significance to the orthodox Jewish community. And, since the requirements of Kashruth are prescribed by Jewish law, the preparation of kosher foods has traditionally been under the exclusive control of the rabbis. See
Cohen
v.
Silver,
*600
The plaintiff further asks that the defendants be enjoined from urging member stores to terminate their association with it and to accept the rabbinical supervision of the “Vaad Harabonim.” At first blush this portion of the bill seems less vulnerable to the defence interposed by the demurrer. The benefits attaching to a contract or to an advantageous business relationship are recognized as property rights and any unjustified interference with their enjoyment is actionable.
Berry
v.
Donovan,
The interlocutory decree sustaining the demurrer is affirmed. A final decree is to be entered dismissing the bill.
So ordered.
