The merger was bitterly opposed by Sri Lankan nationalists. The combined North-East Province occupied one fourth of Sri Lanka. The thought of the rebel Liberation Tigers of Tamil Eelam controlling this province, directly or indirectly, alarmed them greatly. On 14 July 2006, after a long campaign against the merger, the Janatha Vimukthi Peramuna political party filed three separate petitions with the Supreme Court requesting a separate provincial council for the East. On 16 October 2006 the Supreme Court ruled that the proclamations issued by President Jayewardene were null and void and had no legal effect. The North-East Province was formally de-merged into the Northern and Eastern provinces on 1 January 2007.
