Hong Kong's High Court has ruled that a domestic helper from the Philippines should be allowed to apply for permanent residency in the city.The case was brought by Evangeline Banao Vallejos, who has lived in Hong Kong since 1986.
The ruling follows a landmark judicial review and could lead to more than 100,000 other foreign maids winning rights to residency.
The case has sparked widespread debate on equal treatment for foreign maids.
Mark Daly, the lawyer acting on behalf of Ms Vallejos, said that she was very pleased by the ruling, which meant that all domestic helpers now were able to apply for permanent residency.
"It's a good day for the rule of law," he said.
He pointed out that the government had 28 days to appeal.
A spokesman said the government was analysing the judgement and would issue a formal response later in the day.
Public resources
Some critics have said granting residency to domestic helpers would strain the provision of health care, education and public housing.
While other non-Chinese nationals can obtain residency after working in Hong Kong for seven years, immigration rules exclude domestic helpers from seeking permanent residency.
Human rights lawyers and many domestic helpers argue that this is discriminatory.
But some politicians and commentators warned that allowing foreign domestic helpers to have permanent residency would allow them to bring their children and other relatives to the city, who would require education and housing.
There are more than 300,000 foreign domestic helpers in Hong Kong, mainly from Indonesia and the Philippines. It is thought that around 120,000 have lived here for more than seven years.
They are required to live with their employers and cannot accept other jobs.
Without the right to permanent residency, if a maid is dismissed by her employer, she must find another job as a domestic helper or leave Hong Kong within two weeks.
