Transfer of cases: Supreme Court may withdraw or reassign cases to resolve substantial common legal questions. Article 139A empowers the Supreme Court to withdraw cases raising the same or substantially the same questions of law from High Courts and decide them itself when such questions are substantial questions of general importance, and to return withdrawn cases with its judgment for disposal in conformity therewith. The Article also permits the Supreme Court to transfer cases, appeals or proceedings between High Courts when expedient for the ends of justice.
