Professor Cox states the legal effects of the Lincoln Mills decision, and offers three assertions: 1) those involved in arbitration cannot ignore judicial decisions under section 301; 2) the construction of collective bargaining agreements is different from that of other contracts; and 3) Lincoln Mills will affect the respective roles of the court and the arbitrator in actions under section 301. The question of jurisdiction over the issue of arbitrability (the court or the arbitrator) is discussed.
