Municipality of Basilisa, Dinagat Islands - Philippines

Basilisa is a municipality in the province of Surigao del Norte, Philippines. As of the 2007 census, it had a population of 31,363. The town became a part of the province of Dinagat Islands in December 2006, when the province was created from Surigao del Norte by Republic Act No. 9355. However, in February 2010, the Supreme Court ruled that the law was unconstitutional, as the necessary requirements for provincial land area and population were not met. The town reverted back to Surigao del Norte.
