This case marked a divergence from traditional dynamics between Arab states and international institutions. Historically, the region has preferred non-binding arbitration under the purview of a neighbour to international institutions that apply universal statutory law. 78% of states with legal codes based on, or influenced by, Islamic law submit their disputes to an Islamic third party. Even in the lead up to Manama's agreement to participate in the ICJ case, it repeatedly urged Doha to accept regional mediation. The choice to utilize the ICJ is particularly unique considering the divergence between the two legal systems in definitions of sovereignty. Islamic law has a definition of sovereignty that places more emphasis on the people or inhabitants, whereas the ICJ employs a notion of sovereignty based solely on territory. The case was also fundamental to international maritime law for various reasons. It was the first time that the Court applied the equidistance method to a maritime delimitation involving adjacent coasts. A single
maritime equidistant (median) boundary was constructed in two sectors: a southern sector of partially overlapping territorial seas, and a northern sector of partially overlapping continental shelves and Exclusive Economic Zones (EEZs). Interestingly, despite awarding sovereignty of 16 of the 17 elements of the Hawar Islands to Bahrain, the ICJ ruled that the waters between the islands and other Bahraini islands were to be not the
internal waters of Bahrain, but a
territorial sea — meaning all vessels are entitled to the customary right of
innocent passage. In addition, customary law was applied despite neither nations being party to
UNCLOS 1958, and Qatar not having ratified
UNCLOS 1982. As aforementioned, the unique decision to weigh
Qit'at Jaradah's role differently with regard to land/territorial sovereignty and maritime boundaries was also an interesting precedent. ==See also==
