Court hears appeal in permanent residency battle The Court of Appeal starts hearing the government's appeal against a court order in favour of giving Evangeline Banao Vallejos, a Filipino domestic helper who has lived in Hong Kong since 1986, the right to apply for permanent residency. The Court of First Instance ruled in Vallejos' favour in September, leading to an outcry that an influx of new permanent residents would overburden the jobs market, the medical sector and public housing. The government estimates 125,000 helpers who have lived in the city for seven years or more will be entitled to apply if the ruling is upheld. 26 countries join to fight EU tax on aviation emissions Twenty-six countries meet in Moscow to discuss ways to fight the European Union's trading scheme for aviation carbon emissions.

However, economists warn that the city will inevitably be affected by the euro-zone debt crisis, with JP Morgan Chase forecasting late last year that unemployment may rise to 3.8 per cent by the end of this year.
