Quick answer

When many persons are involved in a controversy, the rules allow them to litigate together. A class suit is proper when the subject matter of the controversy is one of common or general interest to many persons so numerous that it is impracticable to join them all as parties, and a number of them who the court finds to be sufficiently numerous and representative may sue or defend for the benefit of all. The key requisites are a common or general interest in the subject matter, a class so numerous that joining everyone is impracticable, and adequate representation by the parties bringing the suit. A class suit is different from a case with merely numerous plaintiffs each asserting their own separate right. Joinder of parties, on the other hand, allows multiple plaintiffs or defendants in one action: permissive joinder is allowed where the rights or liabilities arise from the same transaction or series of transactions and there is a common question of law or fact, while compulsory joinder requires indispensable parties (those without whom no final determination can be had) to be included, or the case may be dismissed.

When many people are wronged by the same act, must each file a separate case? Not necessarily. The rules allow them to litigate together through a class suit or joinder of parties.

What a Class Suit Is

A class suit is proper when:

A number of them who the court finds sufficiently numerous and representative may sue or defend for the benefit of all.

The Requisites of a Class Suit

Class Suit vs. Merely Numerous Plaintiffs

A class suit is not the same as a case with many plaintiffs each asserting a separate right. The distinguishing feature is a common or general interest in the subject matter itself — not many individuals with distinct, personal claims that merely resemble each other. If each person's claim is separate and individual, it is not a true class suit.

Joinder of Parties

Joinder of parties allows multiple plaintiffs or defendants in one action. There are two kinds:

Permissive Joinder

Multiple parties may join where:

Compulsory Joinder

Indispensable parties — those without whom no final determination can be had of the action — must be included. Failure to implead an indispensable party can lead to dismissal, because the court cannot render a valid, complete judgment without them.

Why It Matters

These devices promote efficiency and consistency — avoiding a multiplicity of suits and conflicting rulings — while protecting the rights of those who must be part of the case. Choosing the right vehicle (class suit vs. joinder) depends on whether the interest is common in the subject matter or the parties merely share a related transaction and question.

Frequently Asked Questions

What is a class suit? A suit where the subject matter is of common or general interest to many persons so numerous that joining them all is impracticable, and a sufficiently numerous and representative number of them sue or defend for the benefit of all.

What are the requirements for a valid class suit? A common or general interest in the subject matter, a class so numerous that joining everyone is impracticable, and adequate representation by the parties bringing the suit to protect the interests of all.

How is a class suit different from many plaintiffs suing together? A class suit requires a common or general interest in the subject matter itself. A case with numerous plaintiffs each asserting a separate, individual right is not a true class suit, even if the claims resemble each other.

What is an indispensable party? A party without whom no final determination of the action can be had. Indispensable parties must be joined (compulsory joinder), and failure to implead them can lead to dismissal because a valid, complete judgment cannot be rendered without them.
