Amendment History
Adopted May 22, 2013, eff. October 1, 2013.
Plain-English Summary
Rule 16 lays out how a lawsuit can be brought or defended on behalf of a whole group of people rather than just the named parties. Before a case can proceed as a class action, the court must find that the class is too large for practical joinder, that common questions of law or fact predominate over individual ones, that the claims or defenses of the representative parties are typical of the class, that the representatives and their counsel will adequately protect the class’s interests, and that a class action is the superior way to resolve the dispute.
Once the court certifies a class, the rule addresses what follows: describing the class, aggregating class members’ claims to meet the court’s jurisdictional damages threshold, and giving the class the best notice practicable so members can decide whether to opt out. A member of a plaintiff class who requests exclusion by the deadline in the notice is not bound by the judgment; a member of a defendant class has no such right to opt out.
The rule also shapes the case after certification. The court can issue and alter orders addressing how proceedings unfold and how notice is given, and it can split a case into subclasses, each treated as its own class. A class action cannot be dismissed, discontinued, or settled without the court’s approval, and notice of a proposed dismissal, discontinuance, or settlement must go to the class in whatever manner the court directs.
Frequently Asked Questions
What are the requirements to bring a class action in New Hampshire superior court?
Rule 16(a) requires that the class be too numerous for practical joinder, that common questions of law or fact predominate over individual ones, that the representative parties’ claims or defenses be typical of the class, that the representatives and their counsel adequately protect the class’s interests, and that a class action be superior to other methods of resolving the case.
Can a member of a class opt out of a class action?
A member of a plaintiff class may file an election to be excluded by the date specified in the notice, which removes that person from the class and the judgment. A member of a defendant class may not elect to be excluded.
Does a class action settlement need court approval in New Hampshire?
Yes. Rule 16(k) states that a class action shall not be dismissed, discontinued, or settled without the court’s approval, and notice of the proposed action must be given to the class members as the court directs.
How are damages handled when a class includes many individually small claims?
Rule 16(c) allows the claims of class members to be aggregated for purposes of satisfying the court’s jurisdictional damages limit.
Can a case be handled as a class action for only some of its issues?
Yes. Rule 16(i) allows an action to be brought or maintained as a class action with respect to particular issues, or to be divided into subclasses that are each treated as a class.
