What are the two primary types of joinder in civil procedure?

The correct answer highlights the two fundamental aspects of joinder in civil procedure, focusing on the inclusion of parties and claims in a lawsuit. Joinder of parties refers to the process by which multiple parties can be included in a single action to ensure that all relevant stakeholders are part of the proceedings. This is vital because it allows the court to resolve all related disputes at once, providing a comprehensive resolution and preventing inconsistent judgments.

Joinder of claims involves the ability to bring multiple claims together in one lawsuit, even if those claims are against the same or different defendants. This facilitates judicial efficiency and conserves resources by allowing related claims to be adjudicated within one case rather than multiple separate lawsuits.

Together, these forms of joinder are essential tools in civil procedure, enabling a more efficient court system and promoting judicial economy. The other options suggest different frameworks that do not specifically categorize joinder types as plainly and accurately.
