judgment and granted, sua sponte, summary judgment for the Company declaring the dispute not arbitrable and enjoining the Union from proceeding to arbitration. The Union appealed to this Court.
Arbitration of labor disputes is a matter of contract, not a matter of right.
United Steelworkers of America v. Warrior and Gulf Navigation Company, 363 U.S. 574, 582, 80 S.Ct. 1347, 4 L.Ed.2d 1409 (1960); Local Union No. 787, International Union of Electrical, Radio and Machine Workers, AFL-CIO v. Collins Radio Company, 317 F.2d 214 (5th Cir. 1963). Determination of the arbitrability of this dispute therefore depends upon whether the collective agreement between the Company and the Union requires arbitration. In deciding this question, the permissible scope of the judicial inquiry is narrowly circumscribed by the Steelworkers’ trilogy. United Steelworkers of America v. Enterprise Wheel and Car Corp., 363 U.S. 593, 80 S.Ct. 1358, 4 L.Ed.2d 1424 (1960);
United Steelworkers of America v. Warrior and Gulf Navigation Company, 363 U.S. 574, 80 S.Ct. 1347, 4 L.Ed.2d 1409 (1960); United Steelworkers of America v. American Manufacturing Co., 363 U.S. 564, 80 S.Ct. 1343, 4 L.Ed.2d 1403 (1960). See also Lodge No. 12, District No. 37, International Association of Machinists v. Cameron Iron Works, Inc., 292 F.2d 112 (5th Cir. 1961). We are precluded from “weighing the merits of the grievance, considering whether there is equity in a particular claim, or determining whether there is particular language in the written instrument which will support the claim,” United Steelworkers of America v. American Manufacturing Co.,
supra, 363 U.S. at 568, 80 S.Ct., at 1346, such questions being for the arbitrator alone to decide. Our examination is solely “confined to ascertaining whether the party seeking arbitration is making a claim which on its face is governed by the contract”, United Steelworkers of America v. American Manufacturing Co.,
supra, and whether the parties “did agree to arbitrate the grievance
United Steelworkers of America v. Warrior and Gulf Navigation Company, supra, 363 U.S. at 582, 80 S.Ct., at 1353.
Having made this ‘limited inquiry, we conclude that this is a contractual dispute which the parties agreed to submit to arbitration. Compulsory retirement of employees upon attainment of a certain age and/or years of service to the Company doubtless threatens an employee’s continued tenure .of employment, a right arguably protected by the seniority provisions of the contract. The Union’s claim that operation of the retirement provisions of the Company’s Employee Benefit Plan infringes seniority rights protected by Article XIX .of the collective agreement is therefore a “claim which on its face is governed by the contract”, and which obviously raises questions regarding the interpretation and application of a contract provision, the standard enumerated in Article V for an arbitrable dispute. Thus this claim is appropriate for arbitration under the contract. See Taft Broadcasting Company v. Radio Broadcast Technicians Local Union No. 253 of the International Brotherhood of Electrical Workers, 298 F.2d 707 (5th Cir. 1962).
Of course, this determination is meant to have no reflection upon whether retirements pursuant to the Plan are in fact governed by the seniority provisions of the contract, and, if so, whether Mrs. Wilson’s involuntary retirement violates these provisions. Such questions go to the merits of this dispute and are solely for the arbitrator to decide. See Oil, Chemical and Atomic Workers International Union v. Southern Union Gas Company, 379 F.2d 774 (5th Cir. 1967).
We necessarily reject Southwestern Bell’s contention that Article VII precludes arbitration of this dispute. Article VII provides:
“During the term of this agreement, no change may be made without the consent of the Union in the existing ‘Plan for Employees’ Pensions, Disability Benefits, and Death Benefits’ which
