A gay rights activist attempted to register his marriage in Taipei yesterday, but was told that only a man and woman can legally marry in Taiwan.
Chief Day-way made the attempt two months after gay couple Nelson Chen (Chen Ching-hsueh) and Kao Chih-wei dropped their legal battle to have their marriage recognized.
Chen said he had lost his faith in the judiciary.
Chief said he would now take up the legal fight to have same-sex marriage recognized and appeal the registration office's decision in the Taipei courts, AFP reports.

The day before the parade opposition leader Su Tseng-Chang announce his support for gay marriage, making him the only Asian political leader to do so.
