The maritime boundary between Italy and Slovenia was originally established through a bilateral agreement between Italy and Yugoslavia that was reached in 1975. The boundary extends for 15 nautical miles and is located entirely within the territorial sea of both States. The boundary delimitation was based on a slightly modified version of an equidistance line, and its termination point was formally defined by the 2017 Arbitral Award in the Croatia v. Slovenia land and maritime dispute case. The Arbitral Tribunal officially defined the tripoint between Croatia, Slovenia, and Italy to be located at “Point B” of their boundary award line, with coordinate values of 45° 33′ 57.4″ N, 13° 23′ 04.0″ E.
