The Basic Law does not refer to the Chief Executive of the Hong Kong Special Administrative Region (SAR) nor the provisional legislature in relation to electoral arrangements for the first Legislative Council.
According to the Decision of the National People's Congress (NPC) on forming the first SAR legislature outlined in the Basic Law, the Preparatory Committee (PC) 'shall prescribe' the specific method for forming the first legislature.
The PC's first legislature sub-group has conveniently referred to the decision to confirm the PC's franchise to shape the SAR's first legislature.
It has said it would be unlawful for the provisional legislature to amend the PC's model.
Provisional legislators from the Association of Democracy and People's Livelihood (ADPL) have vowed to amend the electoral rules if they find them disagreeable.
Reportedly, the president of the transitional assembly, Rita Fan Hsu Lai-tai, and provisional legislators from the Democratic Alliance for the Betterment of Hong Kong (DAB) have also reacted cautiously.
