What is a primary purpose of joinder in civil litigation?

The primary purpose of joinder in civil litigation is to ensure all relevant claims are resolved together. This mechanism allows for the efficient handling of related claims and parties in a single legal action, thereby promoting judicial economy and reducing the risk of inconsistent results across separate lawsuits. By allowing parties to join multiple claims or parties in a single action, the court helps to streamline the litigation process and saves resources for both the court and the parties involved.

Other options do not align with the core function of joinder. For instance, appealing before trial or reducing the need for legal representation are not objectives of joinder. In fact, the intent of joinder is to consolidate issues rather than prevent their consolidation, contradicting what the option suggests. Thus, the goal is always to provide a comprehensive, unified resolution to disputes within the same judicial proceeding.
