Local National People's Congress deputies are to carry out detailed studies into the Court of Final Appeal right of abode ruling to decide whether it breached the Basic Law. An 18-member sub-group will soon meet to hold further discussions on how to pursue the issue after failing to reach a consensus. Speaking after a meeting last night, convenor Ng Ching-fai said: 'We found the issue very solemn and important . . . we feel that it's not yet time to search for a consensus. 'The crux of the matter is whether the [Court of Final Appeal] judgment is in accordance with the Basic Law,' he said. The sub-group might hold a joint meeting later with the second NPC sub-group, comprising the remaining 18 local deputies to the NPC, for discussions on the issue. Dr Victor Sit Fung-shuen, a member of the first sub-group, said he found the Court of Final Appeal judgment very regrettable. He said the now-defunct Preparatory Committee's interpretation of Article 24 of the Basic Law had already been endorsed by the National People's Congress in 1996 in the form of working reports. The Preparatory Committee had said mainland children born out of wedlock of Hong Kong permanent residents should not be entitled to right of abode in Hong Kong. 'Any courts in Hong Kong, including the Court of Final Appeal, should make reference to them when making relevant judgments,' he said. He appealed to the SAR and central governments to deal with the matter calmly.
