Justice Frankfurter argued that the Court improperly refused to exercise diversity jurisdiction expressly conferred by Congress. The historic purpose of diversity jurisdiction is to give an out-of-state litigant access to a neutral federal forum for state-law rights that are enforceable in state court. Whether diversity jurisdiction should be narrowed or abolished was a legislative question, not one for judicial revision through equitable discretion.
He distinguished the Court’s earlier abstention decisions. In Pullman and Rowan & Nichols, abstention was warranted because uncertain state-law questions might eliminate the need to decide a serious constitutional issue; the federal court could avoid making only a tentative forecast of state law. Here, however, recent Texas Supreme Court decisions had clearly defined both the meaning of Rule 37 and the standards for reviewing Commission orders, so a federal court could apply those standards in an ordinary judicial proceeding.
Justice Frankfurter also stressed that Texas had not excluded the federal court in Travis County from hearing these suits. In Reagan v. Farmers’ Loan & Trust Co., the Court had construed substantially identical language authorizing suit in a competent court in Travis County to include the federal district court there. Federal courts had accordingly reviewed Railroad Commission orders for decades.
The possibility that federal and state judges might reach different results was not a reason to deny jurisdiction; it was inherent in the congressional premise of diversity jurisdiction. In his view, the majority effectively withdrew a broad category of state-created rights from federal diversity courts merely because those rights affected state policy. Justice Roberts and Justice Reed joined the dissent, and Chief Justice Stone joined it except as to Justice Frankfurter’s discussion of whether diversity jurisdiction should be retained as a matter of legislative policy.
