Massachusetts Emergency Motion to Remand Cause is a legal procedure that allows a party to request the court to return a case to its original jurisdiction. When a lawsuit is removed from state court to federal court by the defendant, the plaintiff may file an emergency motion to remand cause in Massachusetts if they believe that the removal was improper. In this motion, the plaintiff has to explain why the case should be sent back to the state court and provide evidence supporting their argument. There are different types of emergency motions to remand causes that can arise in Massachusetts, including: 1. Lack of federal subject jurisdiction: This type of motion is used when the plaintiff asserts that the federal court does not have the authority to hear the case. The plaintiff might argue that the case does not involve a federal question or that the parties are not diverse enough to warrant federal jurisdiction. 2. Failure to follow proper removal procedure: If the defendant did not comply with the required procedures or failed to meet specific deadlines when removing the case to federal court, the plaintiff can file an emergency motion to remand cause based on procedural errors. 3. Forum non-convenient: In some instances, the plaintiff may argue that the federal court is an inconvenient forum to hear the case. They may propose that the case would be better heard in the state court due to factors such as the convenience of witnesses or the location of evidence. 4. Bad faith removal: The plaintiff can file an emergency motion to remand cause alleging that the defendant removed the case to federal court in bad faith or solely to gain a strategic advantage. This type of motion requires the plaintiff to provide evidence supporting their assertion of bad faith. Overall, an emergency motion to remand cause in Massachusetts is a legal tool used by plaintiffs to request the court to return a case to state court when they believe that the removal to federal court was improper. It is essential for the plaintiff to present a compelling argument based on relevant legal grounds.
