Can plaintiffs with different claims be joined in the same action?

The answer is that plaintiffs with different claims can indeed be joined in the same action if their claims arise from the same transaction or occurrence. This principle is rooted in the efficiency of the judicial process, allowing similar cases to be resolved together rather than requiring multiple separate trials.

Joinder is encouraged when it serves judicial economy and avoids the risk of inconsistent verdicts. When different plaintiffs have claims that stem from a common set of facts or circumstances, it creates a more comprehensive picture of the issues at hand. This promotes the effective and efficient use of court resources and helps to resolve disputes that are closely related, which may otherwise require separate lawsuits, potentially leading to conflicting outcomes.

The other options incorrectly suggest restrictive conditions that do not align with the broader principles of joinder in civil procedure. For example, each claim does not need to be separate, and monetary claims are not the only types that can be joined under these circumstances. Also, the inclusion of co-defendants does not provide a basis for allowing plaintiffs to join their claims in one action outside the context of transaction or occurrence linkage.
