Here's a plain English summary:
This rule points out that class actions work a bit differently than regular lawsuits when it comes to adding required parties. Normally, if someone is missing from a lawsuit but needs to be there for the case to move forward fairly, the court has to bring them in or figure out how to handle their absence. But class actions follow their own separate set of rules for this, found in Rule 23.
In simple terms, this means the usual rules about who must be included in a lawsuit take a back seat when you're dealing with a class action. Instead, Rule 23 controls how class actions handle these situations, since class actions already have built-in ways to represent large groups of people without needing every single person to be individually named in the case.
If you're involved in a class action lawsuit, this means the standard rules about required parties don't fully apply to you. Your case will follow the specific procedures laid out in Rule 23 instead, which are designed to handle the unique challenges of representing many people at once.
