Indefinite detention is the incarceration of an arrested person by a national government or law enforcement agency without a trial. It is a controversial practice on the part of any government or agency that is in violation of many national and international laws, including human rights laws. In recent years, governments have indefinitely held those suspected to be involved in terrorism, declaring them as enemy combatants.
Most of the civilized nations of the world and human rights groups hold unfavorable views of indefinite detention.
In 1994, indefinite detention was introduced to Australia new legislation removed the 273 day limit imposed on Vietnamese, Chinese, and Cambodian refugees; previous laws had also allowed for the indefinite detention of specified people. In 2004, Australia's high court ruled in the case Al-Kateb v Godwin that the indefinite detention of a stateless person is lawful.
The Internal Security Act an act enforced since 1960 is a preventive detention law enforced in Malaysia which allows indefinite detention without trial for 2 years and further extension as needed.

In the United States, indefinite detention has been used to hold terror suspects. This process, which has been highly controversial, is currently under review. According to the American Civil Liberties Union, section 412 of the USA PATRIOT act permits indefinite detention of immigrants; one of the most highly publicized cases has been that of Jose Padilla, whose ultimate prosecution and conviction in the United States have also been highly controversial. The International Red Cross has criticized the indefinite detention of prisoners at Guantanamo Bay.
On December 5, 2008, the United States Supreme Court announced that it will rule on indefinite detention. On November 29, 2011, the United States Senate rejected a proposed amendment to the National Defense Authorization Act for Fiscal Year 2012 ("NDAA") that would have banned indefinite detention by the United States government of its own citizens, leading to criticism that Habeas corpus in the United States has been undermined. Congress and Senate approved the National Defense Authorization Act in December 2011 and President Barack Obama signed it December 31, 2011. The new indefinite detention provision of the law was decried as a "historic assault on American liberty." The American Civil Liberties Union stated that “President Obama's action today is a blight on his legacy because he will forever be known as the president who signed indefinite detention without charge or trial into law.” On May 16, 2012, in response to a lawsuit filed by journalist Chris Hedges, Noam Chomsky, Naomi Wolf and others, United States District Judge Katherine B. Forrest ruled the indefinite detention section of the law (1021) likely violates the 1st and 5th Amendments and issued a preliminary injunction preventing the US government from enforcing it.
