Narrative Opinion Summary
This case involves a boundary dispute between New Jersey and Delaware over the Delaware Bay and River, brought under the Supreme Court's original jurisdiction. The primary legal issues revolve around the title to the riverbed within a twelve-mile circle of New Castle and the boundary line in the river and bay below this circle. Delaware claims ownership of the entire riverbed within the circle based on historical deeds, notably from the Duke of York to William Penn, which New Jersey contests. The special master appointed by the court favored Delaware's claim within the twelve-mile circle while siding with New Jersey for the bay and river below. The court affirms Delaware's title to the riverbed within the circle, grounded in historical grants, and applies the Thalweg doctrine to determine the boundary below the circle. This doctrine dictates that the boundary follows the middle of the main navigational channel, ensuring equitable access to the river for both states. The court's decision reflects a balance of historical context and international law principles, resulting in shared litigation costs between the parties. The ruling underscores the enduring influence of historical deeds and legal principles in resolving interstate boundary disputes.
