Full Text of Rule 1.272
Plain-English Summary
The whole point of a class action is that one judgment resolves the claim for everyone in the class, not just the named parties. Rule 1.272 delivers on that: once a class action is certified under rule 1.262 and notice has gone out under rule 1.266 or rule 1.271, the judgment on the claim, or the particular claim or issue certified, binds every class member who did not file an election of exclusion under rule 1.267.
The binding effect runs according to the judgment's own terms -- a judgment certified as to a specific issue binds the class on that issue, not on matters outside what was certified. And the rule requires transparency about exactly who is covered: the judgment itself must name or describe the class members bound by it, so there is no ambiguity later about whose rights were resolved by the case.
Frequently Asked Questions
Am I bound by a class action judgment even if I never actively participated in the case?
Yes, if you were a class member who did not file a timely election of exclusion under rule 1.267, and the required notice was given under rule 1.266 or rule 1.271, rule 1.272 binds you to the judgment.
What if I opted out of the class action?
You are not bound. Rule 1.272 applies only to class members who have not filed an election of exclusion, so opting out under rule 1.267 keeps you outside the judgment's binding effect.
Does the judgment have to identify who exactly is bound by it?
Yes. Rule 1.272 requires the judgment to name or describe the members of the class who are bound by its terms.
If the court certified only one issue for class treatment, does the judgment bind the class on everything?
No. Rule 1.272 binds class members only “according to its terms,” meaning the judgment binds the class on the claim or the particular claim or issue certified, not on unrelated matters.
What has to happen before a class judgment can bind absent members?
The action must have been certified under rule 1.262, and notice must have been given under rule 1.266 or rule 1.271, before rule 1.272's binding effect applies.
