Gabon is a republic with a presidential form of government dominated by the Gabonese Democratic Party (PDG), which has held power since 1968. Observers characterized the 2011 legislative elections as generally free and fair, although some opposition parties boycotted them, citing the government's inability to provide for full transparency and to prevent voter irregularities. PDG candidates won 114 of 120 seats in the National Assembly. Security forces reported to civilian authorities, who generally maintained effective control over them. In some cases, however, security force personnel committed human rights abuses. The most important human rights problems in the country were harsh prison conditions, lengthy pretrial detention, and ritual killings. Other major human rights problems included: use of excessive force by police; an inefficient judiciary subject to government influence; restrictions on privacy and the press; harassment and extortion of African immigrants and refugees; widespread government corruption; violence against women; societal discrimination against women, noncitizen Africans, Pygmies, and persons with HIV/AIDS; trafficking in persons, particularly children; and forced child labor. The government sometimes took steps to prosecute and punish officials who committed abuses. During the year authorities disciplined, including with dismissal, police officers who used excessive force. Impunity remained a problem, however.
