§ 312 Additional parties; supplemental process

If someone who should be part of a court case isn't included yet, the court can fix that. The judge can order extra paperwork, called supplemental process, to bring that person into the case. This can happen at any point while the case is going on, not just at the beginning.

The court can tell any party already involved in the case to get this paperwork done and have it delivered to the missing person. This delivery has to follow the same rules used for regular notices in other parts of the law (sections 307 and 308). The goal is simple: make sure everyone who needs to be part of the case is actually included, so the court can make a fair and complete decision.

This matters because leaving out an important person could cause problems later. If someone with a real stake in the outcome isn't notified, the final decision might not hold up or might not fully settle the matter. This rule gives the court a way to catch that problem and bring the right people in before it's too late.
