What is the likely outcome for supplemental claims when the original claims are dismissed?

When original claims are dismissed, the likely outcome for supplemental claims is that they are typically dismissed. This is grounded in the principles of supplemental jurisdiction under 28 U.S.C. § 1367. Supplemental jurisdiction is intended to allow federal courts to hear additional claims that are related to the original claim, ensuring that the court can resolve all claims arising from a common nucleus of operative fact in a single proceeding. However, if the original claims are dismissed, the basis for keeping the supplemental claims in federal court may no longer exist, as they often depend on the primary claim for their viability.

Consequently, without the original claims to anchor them, it's unlikely that supplemental claims can justify remaining in the federal court system. As such, courts generally do not exercise supplemental jurisdiction over these dismissed claims and will dismiss them. This aligns with the legal principles set out in decisions like United Mine Workers of America v. Gibbs, which emphasizes the importance of the original claims for the continued presence of supplemental claims.
