In what situation is permissive joinder NOT appropriate?

Permissive joinder allows multiple parties to join in a single action when their claims share a commonality that relates them to one another, either through common questions of law or fact, or because they involve similar events.

The reason why the situation involving different legal issues would not be appropriate for permissive joinder is that this principle encourages the consolidation of related claims to streamline the adjudication process. When claims arise from entirely different legal issues, they do not meet the standard of relatedness necessary for permissive joinder. This lack of connection means that trying these claims together may lead to confusion, inefficiency, and complicate the legal proceedings without a shared context.

In contrast, situations where claims arise from the same event, share common questions of law, or involve the same defendant typically provide the necessary connection for efficient adjudication and fall squarely within the framework of permissive joinder, making them suitable for being tried together.
