What district courts have jurisdiction over the lawsuit involving the salesman and two investors?

In determining which district courts have jurisdiction over a lawsuit involving parties from different states, one key concept is diversity jurisdiction. For diversity jurisdiction to apply, the parties must be citizens of different states and the amount in controversy must exceed a certain threshold.

In this scenario, since you have a salesman from State A and two investors from State C, the lawsuit can be filed in any state court that provides a suitable forum, specifically, in the district courts of either State A or State C. This is because the jurisdiction rules allow the plaintiff to choose a forum based on where the defendant resides or where a relevant event occurred, impacting the court's convenience and fairness.

Jurisdiction can often be exercised in the state where the defendant resides (where the investors are from) or where the events giving rise to the lawsuit occurred (if those events occurred in State A). Consequently, the district courts in both State A and State C can properly exercise jurisdiction over the matter, providing a reasonable basis for lawsuit proceedings given the interstate nature of the parties involved.

The focus on states A and C supports the concept of allowing litigation to occur in a jurisdiction that relates closely to the parties’ disputes and ensures the interests of justice are served by both parties having access to relevant courts
