After being re-elected in 2004, Biya was barred by a two-term limit in the 1996 Constitution from running for President again in 2011, but he sought to revise this to allow him to run again. In his 2008 New Year's message, Biya expressed support for revising the Constitution, saying that it was undemocratic to limit the people's choice. The proposed removal of term limits was among the grievances expressed during violent protests in late February 2008. Nevertheless, on 10 April 2008, the National Assembly voted to change the Constitution to remove term limits. Given the RDPC's control of the National Assembly, the change was overwhelmingly approved, with 157 votes in favor and five opposed; the 15 deputies of the SDF chose to boycott the vote in protest. The change also provided for the President to enjoy immunity from prosecution for his actions as President after leaving office.
"Tyrants, the World's 20 Worst Living Dictators", by David Wallechinsky, ranked Biya with three others commonly in sub-Saharan Africa: Robert Mugabe of Zimbabwe, Teodoro Obiang Nguema Mbasogo of Equatorial Guinea, and King Mswati of Swaziland. He describes Cameroon's electoral process in these terms: "Every few years, Biya stages an election to justify his continuing reign, but these elections have no credibility. In fact, Biya is credited with a creative innovation in the world of phony elections. In 2004, annoyed by the criticisms of international vote-monitoring groups, he paid for his own set of international observers, six ex-U.S. congressmen, who certified his election as free and fair." In a 2005 interview William Quantrill, a retired member of HM Diplomatic Service, argued that the reluctance of Biya to delegate responsibility seriously hampered the quality of governance, with trivial decisions often delayed until he got round to delivering them, and that there was too much government interference in the economy in general.
