criminality and organized crime, including measures that entail restrictions or even deprivations
of personal liberty. Despite this, the State does not have unlimited power to achieve these ends,
irrespective of the gravity of some actions and of the guilt of the alleged perpetrators. In particular,
the authorities cannot violate the rights recognized in the American Convention, such as the rights
to the presumption of innocence, to personal liberty, and to due process and, among other
measures, they cannot carry out unlawful or arbitrary arrests.184
116. The Court has indicated that the essential content of Article 7 of the Convention is the
protection of the liberty of the individual against any arbitrary or unlawful interference by the
State.185 The Court has also indicated that this article includes two types of regulation: one general
and one specific. The general aspect is found in the first paragraph, while the specific aspect is
contained in paragraphs 2 to 7; any violation of those paragraphs necessarily results in the
violation of Article 7(1) of the American Convention.186
117. An unlawful deprivation of liberty violates Article 7(2) of the Convention, and occurs when
the applicable domestic law is not observed.187 The Court has explained that the restriction of the
right to personal liberty “is only viable when it occurs based on the causes and conditions
previously established by the Constitution or by the laws enacted in conformity with the latter
(substantive aspect) and, also, strictly subject to the procedures that they objectively define
(formal aspect).”188 Regarding the requirement of lawfulness and the authority of the police to
arrest an individual, the Court understands that it should be recalled that improper action by the
law enforcement agencies represents “one of the main threats to the right to personal liberty.”189
Therefore, the regulations which determine the authority of police to prevent and to investigate
crime must include clear and specific references to parameters that prevent detentions that are
arbitrary or contrary to constitutional mandates.190
118. Moreover, it should be noted that the arbitrary nature of a deprivation of liberty, prohibited
by Article 7(3) of the Convention, is not distinguished merely by being contrary to the law; rather,
it includes elements of impropriety, injustice and unpredictability.191 Accordingly, the deprivation
of liberty may be arbitrary if it is conducted based on “reasons and methods that – even though
