A voluntary worker who was abandoned by his parents as a young child is going to court to fight for the right to marry the woman he loves. Musa Anwar, 34, who works with children, has been denied permission to wed because his bizarre background has led the Registrar of Marriages to have 'grave doubts' about his identity. 'The right to marry is a basic human right, a constitutionally protected right recognised under the Basic Law,' says his challenge to the decision lodged with the High Court. Mr Anwar believes he was born on May 5, 1965, in a horse-drawn caravan in Kazakhstan where his parents were poor nomads. His application says he has never possessed a birth certificate and 'only knows his name because his mother wrote it on the clothing he was wearing before abandoning him'. He was then looked after by an elderly man who died when he was eight, leaving him to become a street child. When 15 he met an 'underworld businessman' who smuggled him to northeastern China where he fixed cars and worked in a gold mine. He came to Hong Kong in December 1993 as an illegal immigrant, his application says. He was detained by the Immigration Department but after failing to deport him it released him in November 1994. His application states: 'He had $5 on his release and was told he was not permitted to work. Mr Anwar became a street sleeper.' The Social Welfare Department gave him $3,000 in the first six months after his release but refused to give him further support. Mr Anwar began working as a volunteer at Mother's Choice charity organisation, which offered him a place to live in December 1996, the application says. He fell in love with Filipina Genoveva Malilay in 1996 but last year the pair were refused permission to marry because Mr Anwar could not produce proof of his identity. Mr Anwar will be asking a judge to order the Registrar of Marriages to permit him to file a notice of intended marriage so he can wed.
