Here is a retweet from Neal Katyal with the summary of the court’s ruling in a Pennsylvania case.
And here is the legal definition of “with prejudice.” In brief, that means that the judge said in effect go away and don’t come back.
From Wikipedia: Two of the more common applications of the word are as part of the terms “with prejudice” and “without prejudice”. In general, an action taken with prejudice is final. For example, “dismissal with prejudice” forbids a party to refile the case, and might occur either because of misconduct on the part of the party who filed the claim or criminal complaint, or the result of an out of court agreement or settlement. Dismissal “without prejudice” (in Latin, salvis iuribus) allows the party the option to refile, and is often a response to procedural or technical problems with the filing that the party could correct when filing again.
