A motion for preliminary injunction is a request made to a court seeking to prevent a party from taking certain actions until a final decision is made in a legal case. This motion is typically filed before the trial and aims to preserve the status quo or prevent irreparable harm while the case is ongoing. Courts consider various factors such as the likelihood of success on the merits, potential for irreparable harm, and the balance of equities between the parties when deciding whether to grant such a motion.
