Arbitrary deprivation of liberty refers to cases when it is clearly impossible to invoke any legal basis justifying the deprivation of liberty; when the deprivation of liberty results from the exercise of the rights or freedoms guaranteed by articles of the Universal Declaration of Human Rights and, insofar as States parties are concerned, by of the International Covenant on Civil and Political Rights; when the total or partial non-observance of international norms relating to the right to a fair trial, established in the Universal Declaration of Human Rights and in the relevant international instruments accepted by the State concerned, is of such gravity as to give the deprivation of liberty an arbitrary character; and when the deprivation of liberty constitutes a violation of international law for reasons of discrimination based on birth; national, ethnic or social origin; language; religion; economic condition; political or other opinion; gender; sexual orientation; or disability or other status, and which aims towards or can result in ignoring the equality of human rights.
