The Constitution of Jordan guarantees freedom of opinion and speech, in addition to freedom of the press and mass media, but all within the limits of the law. According to the U.S. Department of State, in practice there are significant restrictions in place curtailing the free operation of the media. Any criticism or defamation of the king or royal family is prohibited, as well as anything deemed to harm "the state’s reputation and dignity." The government has used tactics such as the threat of fines, prosecution, and detention to intimidate journalists and encourage self-censorship. Moreover, informants and censors at printing presses often give the government warning if a particularly inflammatory article is slated for publication, thereby allowing the government to apply pressure on the publisher to change or remove the item. King Abdullah issued a statement outlawing imprisonment of journalists, earning praise from human rights groups. Additionally, the Press and Publications Law and the Press Association Law impose certain limitations on the accreditation of journalists and the operation of newspapers; more damaging perhaps is the government’s unwillingness to advertise in newspapers not at least partially owned by the state. Jordanian radio and television are even more restricted in their freedoms than the press. Internet access in the kingdom is generally open and unrestricted, although there were past reports of government investigations into the sources of overly critical Internet sites.
