A district court may not, sua sponte, remand an action to state court for procedural defects in the removal, but may do so only on a timely remand motion. Procedural defects in a removal, such as untimeliness—i.e., more than 30 days after service if the complaint discloses that it is removable or more than a year after the complaint is filed—are waived unless the plaintiff files a timely motion for remand. The district court lacks authority to remand a removed case sua sponte for a procedural defect. Because the district court exceeded its authority in remanding this case for a procedural defect even though plaintiff failed to move for remand, the Court of Appeal had jurisdiction to review and reverse the remand order under 28 USC 1447(d).
