Here's a plain English summary of this rule:
Sometimes a court order affects someone who isn't officially part of the lawsuit. This rule says that if an order gives benefits to a person outside the case, or if it could be enforced against them, the court treats that person the same way it would treat an actual party in the case.
In practical terms, this means the process for making someone follow a court order doesn't change just because they weren't named in the original lawsuit. If the order applies to them, they can enforce their rights under it, or have it enforced against them, using the same steps that parties to the case would use.
This rule protects fairness. It stops people from avoiding a court order simply because they weren't officially listed as a party. It also lets outside people benefit from an order if the order was written to help them, even though they didn't file the lawsuit themselves.
