Honduras claims Serranilla Bank as part of its national territory in Article 10 of its Constitution.[28] In 1986, it agreed upon a maritime boundary demarcation with Colombia that excluded Honduras of any control over the bank or its surrounding waters.[2][29] The ratification of this boundary on 20 December 1999[30] proved to be controversial within Honduras, as it ensured that the state implicitly recognised Colombia's sovereignty over the claimed territory.[31] Nicaragua, which has not resolved its maritime borders with Honduras or Colombia, disputed Honduras' legal right to hand over these areas before the ICJ.[6][32] Despite the agreement with Colombia, however, the Honduran government has yet to officially renounce the claim in the Constitution.
