§ 77 May be several actions on same security.

If you have a security agreement (like a bond or a similar legal document that guarantees payment or performance), you're not limited to just one lawsuit over it. If someone breaks a promise or fails to pay under that agreement, and you win a judgment against them for that specific failure, you can still sue again later if they mess up again in a different way.

This means one lawsuit and one judgment don't use up all your rights under the security. Each time there's a new problem or a new failure to live up to the agreement, you can start a new legal case about that specific issue. This applies whether it's the same person suing again or someone else with rights under the same agreement.

In simple terms, winning or losing a case about one problem with a security agreement doesn't stop future lawsuits about other problems with that same agreement. Each failure or delinquency can be treated as its own legal issue.
