This summary is not the rule. The rule text controls.
If someone gets a court order making an out-of-state judgment enforceable in Louisiana, the person who owes the money still has a way to fight it. They can ask the court to stop enforcement of that judgment through an injunction, but only if they can show the judgment is no longer valid. This might be because the debt has already been paid off, too much time has passed under the law, or some other legal reason makes it impossible to enforce anymore.
However, there's a catch. Before a court will issue an order temporarily stopping enforcement (whether it's a short-term restraining order or a longer preliminary injunction), the person asking for it must put up security, like a bond. This protects the other side in case the injunction turns out to be wrongly granted, since money or property could be tied up while the case is being sorted out.
In short, this rule gives people a legal path to challenge an enforceable judgment if it's actually invalid, but it requires them to back up that request with a financial guarantee first.
