What is one of the main reasons for allowing supplemental jurisdiction?

The main reason for allowing supplemental jurisdiction is to ensure that all claims related to a primary claim are heard together. This principle is rooted in judicial efficiency and the desire to avoid fragmented litigation. By allowing related claims to be resolved in the same proceeding, the court can promote consistency in the outcomes and minimize the risk of conflicting judgments.

This approach enables the judicial system to address the whole controversy at once, saving time and resources for both the courts and the parties involved. It also helps to maintain the integrity of the judicial process, as parties can fully litigate all matters arising from a single transaction or occurrence without the need for multiple lawsuits.

While other options might suggest various motivations, they do not align with the fundamental goal of supplemental jurisdiction, which is clearly focused on connecting related claims to facilitate a more cohesive and efficient judicial process.
