What is the relevance of "substantial connection" in assessing jurisdiction?

The concept of "substantial connection" is crucial in establishing personal jurisdiction because it serves to justify asserting jurisdiction over a defendant by demonstrating that the defendant has sufficient ties to the forum state. This connection may arise from the defendant’s activities, conduct, or presence within the state, which are deemed relevant to the legal claims being brought against them.

When a court determines that a defendant has a substantial connection to the forum state, it indicates that it is reasonable and fair for that court to exercise its jurisdiction. For instance, if a defendant conducts business, enters contracts, or commits acts within the state, these factors contribute to the assessment of whether the state has a legitimate interest in adjudicating the case. Thus, establishing a substantial connection ensures that the court's exercise of jurisdiction meets both the requirements of due process and the principles of fairness inherent in the legal system.
