Hungary's record of press freedom and human rights deteriorated in 2013, resulting in calls from some European lawmakers to suspend the country's voting rights in the European Union. Authorities adopted controversial changes to the constitution in March, including a provision limiting pre-election political advertising solely to broadcasters--most of which are controlled by or affiliated with allies of Prime Minister Viktor Orban. The amendments also curtailed the powers of Hungary's Constitutional Court by taking away its right to strike down unconstitutional laws. After news outlets tried to investigate allegations of government corruption, lawmakers introduced amendments to the Freedom of Information Act, restricting the amount of government data that individuals and nongovernmental groups, including media outlets, could access. In August, Orban faced criticism from press freedom advocates after he nominated an ally of his party, Fidesz, to lead the national Media Authority, which regulates all domestic and international media--including print, broadcast, and the Internet--as well as their publishers and service providers. In November, the Hungarian Parliament adopted the criminalization of libel, two weeks after the amendment was proposed by lawmakers.
