Hong Kong Chief Executive election, 2012: The 2012 Hong Kong Chief Executive election was held on 25 March 2012 to select the Chief Executive of Hong Kong (CE), the highest office in the Hong Kong Special Administrative Region (HKSAR), by a 1,193-member Election Committee (EC) to replace the incumbent Chief Executive.

Right of abode in Hong Kong: The right of abode in Hong Kong is the right to legally reside in Hong Kong without any limit or condition of stay being imposed by the Hong Kong Immigration Department.  As the People's Republic of China stood to resume sovereignty over Hong Kong from the United Kingdom, the nationality of Hong Kong people as well as their right of abode in the territory was formalised prior to the 1997 handover.  Since Hong Kong has never been an independent country, there is no provision for its own citizenship status.  Hong Kong Permanent Resident is the legal status for those who have the right of abode in Hong Kong, which is the "de-facto" citizenship status in Hong Kong.  Most citizen rights in Hong Kong (such as the right to vote) are granted to all permanent residents, while some (such as the right to hold a HKSAR passport, or becoming a high-rank public officer such as the Chief Executive) are restricted to permanent residents who are also Chinese citizens.

Due to the new arrangements agreed in a contentious LegCo vote in 2010, the session consists of the new total of 70 seats in LegCo, ten more than previously, with 35 members elected in geographical constituencies through direct elections, and 35 members in functional constituencies, in which five District Council (Second) functional constituency seats each represent all 18 District Councils of Hong Kong voted for by all resident voters in Hong Kong (who did not have a vote in any other functional constituency).  The Democratic Alliance for the Betterment and Progress of Hong Kong remained the largest party while the pan-democrats secured the one-third crucial minority.  Notable new members of the LegCo members include Gary Fan from the new established party Neo Democrats and first openly gay councillor, People Power's Ray Chan Chi-chuen.
