Political censorship exists when a government attempts to conceal, fake, distort, or falsify information that its citizens receive by suppressing or crowding out political news that the public might receive through news outlets. In the absence of neutral and objective information, people will be unable to dissent with the government or political party in charge. The term also extends to the systematic suppression of views that are contrary to those of the government in power. The government often possesses the power of the army and the secret police, to enforce the compliance of journalists with the will of the authorities to spread the story that the ruling authorities want people to believe. At times this involves bribery, defamation, imprisonment, and even assassination.
Over the course of history, many nations and political organisations have utilised political censorship and propaganda in order to manipulate the public. The Ancien régime, for example, is well known for having implemented censorship.
In 1851, Napoleon III declared himself emperor. The wealthier citizens immediately saw in him a way to protect their privileges, that were put in danger by the French Revolution of 1848, which threatened to re-organise the social hierarchy. This was a time when all sorts of cultural productions was censored, from newspapers to plays.
Independent journalism did not exist in the Soviet Union until Mikhail Gorbachev became its leader; all reporting was directed by the Communist Party. Pravda, the predominant newspaper in the Soviet Union, had a near-monopoly. Foreign newspapers were available only if they were published by Communist Parties sympathetic to the Soviet Union.
In 1973, a military coup took power in Uruguay, and the state employed censorship. For example, writer Eduardo Galeano was imprisoned and later was forced to flee. His book Open Veins of Latin America was banned by the right-wing military government, not only in Uruguay, but also in Chile and Argentina.
Many countries' campaign finance laws restrict speech on candidates and political issues. In Citizens United v. FEC, the United States Supreme Court found that many such restrictions are an unconstitutional form of censorship.
In the Republic of Singapore, Section 33 of the Films Act bans of the making, distribution and exhibition of "party political films", at pain of a fine not exceeding $100,000 or to imprisonment for a term not exceeding 2 years. The Act further defines a "party political film" as any film or video
In 2001, the short documentary called A Vision of Persistence on opposition politician J. B. Jeyaretnam was also banned for being a "party political film". The makers of the documentary, all lecturers at the Ngee Ann Polytechnic, later submitted written apologies and withdrew the documentary from being screened at the 2001 Singapore International Film Festival in April, having been told they could be charged in court. Another short documentary called Singapore Rebel by Martyn See, which documented Singapore Democratic Party leader Dr Chee Soon Juan's acts of civil disobedience, was banned from the 2005 Singapore International Film Festival on the same grounds and See is being investigated for possible violations of the Films Act.
This law, however, is often disregarded when such political films are made supporting the ruling People's Action Party (PAP). Channel NewsAsia's five-part documentary series on Singapore's PAP ministers in 2005, for example, was not considered a party political film.
