In what circumstances has the federal court refused to grant declaratory relief?

However, we have not burdened the district court with a remand when the facts and circumstances appearing in the record demonstrate that federal declaratory relief was unquestionably appropriate. For example, when the district court is also presented with nondeclaratory claims within its diversity jurisdiction which present the same issues, the usual argument for federal abstention is absent. In such cases, "whether the district court decided the entire controversy, or refrained from deciding part of it, major issues of state law necessarily had to be decided in federal court."
