The automatic transition (or the "through-train" model) was abandoned on 31 August 1994, when the NPC decided the 1995 Legislative Council would end with British sovereignty over Hong Kong. The policy changed when the Hong Kong government decided the 1995 legislature would be formed with a new electoral formula from the 1994 electoral reform announced by Hong Kong Governor Chris Patten in October 1992. Although the new formula expanded Hong Kong's electoral base, it conformed with the seat composition described in the NPC decision by only allowing 33 percent of seats to be elected through universal suffrage. This was possible only because decision did not define the election committee and the functional constituency electorate.
