cause, and therefore arbitrable. The problem illustrates the tension between provisions contained in two agreements entered into by the company and the union — the collective bargaining agreement, known as the IATSE, Local # 804, KYW-TV Agreement, and the Pension and Insurance Agreement.
Article IX of the collective bargaining agreement described the company’s right “to discharge any of its employees for just cause.” App. at 39a. Article XI of the agreement, entitled “Grievance and Arbitration,” provided that all grievances, disputes and differences with respect to the interpretation or application of the agreement were to be resolved through the grievance procedure, which culminated in final and binding arbitration. Article V of the collective bargaining agreement disclosed that the parties “have executed a Pension, Insurance and Personal Savings Plan Agreement which extends the benefits of those Plans to the employes covered by this Agreement.” App. at 33a.1 Article I, Section 3(a) of the Pension and Insurance Agreement provided that its terms “are accepted by the Union, for the duration of this Agreement, as a complete insurance, pension and savings program.” App. at 60a. Section 3(b) provided:
It is further understood that no matter respecting any Plan provided by this Agreement or any differences arising under any such Plan, or [] concerning any benefits payable by the Company under any such Plan or any benefits the payment of which could or might be insured by the Company, shall be subject to any grievance or arbitration procedure which may be established by agreement between the Company and the Union.

What has triggered the immediate dispute is a compulsory retirement provision contained in neither the collective bargaining nor the Pension and Insurance agreements, but set forth in the Westinghouse Pension Plan, a plan specifically referred to in Article I, Section 3(a) of the Pension and Insurance Agreement. Section 2.A of the Westinghouse Pension Plan provided:
[A]n Employe shall retire from service with his Employer on the first day of the month following the month in which his 65th birthday occurs. .

Although this matter is before us on appeal from a summary judgment, the parties agreed at oral argument that no material issue of fact prevented a proper exercise of the summary judgment power of the district court. The litigants before us continue to maintain the positions they asserted before the district court. For its part, the company relies on Section 3(b), the non-arbitrability provision of the Pension and Insurance Agreement. The union responds that this language must not be interpreted in vacuo. This section refers only to controversies over details of the plan, the union contends, whereas the overarching issue of compulsory retirement at age sixty-five is governed by Articles IX and XI of the collective bargaining agreement.
The district court did not decide the arbitrability issue clearly in favor of either side. Although it ordered the matter to arbitration, its order reserved to the parties the right to challenge the arbitrator’s jurisdiction. The district court’s oral opinion in support of its order goes even further, and we believe that a fair reading of that opinion supports the conclusion that the district court was willing to delegate to the arbitrator the power and authority to determine the arbitrability vel non of the issue. For example, the court stated: “It seems to me that this is a case where it is possible for the arbitrator to determine . . . that this is a dispute within the terms of the agreement. . . . ” App. at 168a. Here the court erred, and in so doing, based its reasoning on an improper interpretation of International Union of Electrical, Radio and Machine Workers Local 103 v. RCA Corp.,
