Narrative Opinion Summary
The Supreme Court of the United States adjudicated a boundary dispute between the states of New Jersey and Delaware, issuing a definitive decree on June 3, 1935. The case centered on the delineation of territorial boundaries within a 12-mile radius of the New Castle courthouse, establishing Delaware's dominion over the Delaware River and associated subaqueous soil up to the mean low-water line on the New Jersey side. Beyond this radius, the boundary is defined as the center of the main ship channel in the Delaware River and Bay. The Court relied on a special master's report and a comprehensive boundary description, supported by U.S. Coast and Geodetic Survey charts, to articulate the boundaries. Jurisdiction is maintained by the Court to address potential future modifications due to geographical shifts. The decree also includes a permanent injunction prohibiting either state from challenging the sovereignty of the areas awarded to the other, and mandates an equal division of litigation costs between the parties. This ruling does not impinge upon rights established under a prior 1905 compact agreement between the states.
