§ 1389 Injunction not granted where motion overruled on merits - Inferior court not to grant.

If a judge or court looks at your request for an injunction and turns it down based on the actual facts and legal arguments, you can't just ask another judge in the same court to grant it. That door is closed once the merits have been decided.

The rule also stops people from shopping around for a more favorable court. If the court where you originally filed your case says no to your injunction request, you can't go to a lower court and try to get approval there instead. The decision from the original court sticks, and lower courts don't get to overrule it.

Basically, this rule stops people from asking again and again in hopes of getting a different answer. Once a court has genuinely reviewed your request and denied it, that decision stands unless you appeal to a higher court.
