Prior to gaining separate representation, areas now under the jurisdiction of Dinagat Islands were initially represented under the former province of Surigao (1907–1961), Region X (1978–1984) and Surigao del Norte (1961–1972; 1984–2007).
Despite Dinagat Islands being nullified as a province by the Supreme Court of the Philippines on February 11, 2010[2] the decision was not yet rendered final and executory before the May 10, 2010 elections; therefore the Commission on Elections still organized the elections for Dinagat Islands' congressional representative along with its provincial officials.[3] Even after the Supreme Court rendered its original decision final and executory on May 18, 2010, the representatives of the reconfigured first district of Surigao del Norte and the lone district of Dinagat Islands continued to represent their own constituencies.[4]
After the Supreme Court reversed its previous ruling on April 12, 2011,[4] and subsequently upheld with finality the constitutionality of R.A. 9355 and the creation of Dinagat Islands as a province through an Entry of Judgment on October 24, 2012,[5] the separation of Dinagat Islands from Surigao del Norte's first district became permanent.
