Adler Construction Co. v. United States

holding plaintiff waives right to remand where no timely request for remand made | limiting Haley on to cases where the joint tortfeasor against whom contribution is sought is immune from tort liability by statute | oral argument was dispensed with because issues were manifestly simple and clear, legal citations were fully dispositive of the issues, and it was concluded that no useful purpose could be served by oral argument | federal jurisdiction may be challenged at any stage, even by party who invoked it | decision below allowing contribution affirmed
