[1] The Court of First Instance of the High Court (CFI) held in December 2008 that the Administration should provide legal assistance to a torture claimant during the screening process and provide suitable training for the decision makers. The Immigration Department (ImmD) then suspended all screening works.
[2] The Legislative Council passed the Immigration (Amendment) Ordinance 2009 in November 2009, making it an offence for illegal immigrants to take any employment or establish or join in any business. The ImmD implemented the enhanced administrative mechanism in December 2009.
[3] This includes 93 reviewed cases.
