region,115 and of Argentina,116 as well as the practice of international courts,117 it is an
additional presumption to the other requirements of a legitimate purpose, appropriateness,
necessity and proportionality and operates as a supplementary guarantee when ordering a
precautionary measure that restricts liberty.

The foregoing should be understood by considering that, in principle and in general
terms, this decision should not have any effect on the person who decides the responsibility
the accused, since it is usually made by a judge or by a judicial authority other than that
which decides on the merits.118

Moreover, the Court has held that a suspicion or sufficient evidence that permits a
reasonable presumption that the person subjected to trial has participated in the unlawful act
under investigation must be substantiated and expressed on specific acts; in other words, not
on mere conjectures or abstract intuitions. Thus, the State “must not arrest someone in order
to then investigate him; rather, it is only authorized to deprive a person of his liberty when
there is sufficient information to be able to bring him to trial.”119 In the same regard, the
European Court has held that the term “suspicion or reasonable indicia” presupposes the
existence of “some facts or information which would satisfy an objective observer that the
person concerned may have committed the offence in question.”120
ii. Test of proportionality

Regarding the second point, the Court has held that the judicial authority must
consider proportionality when ordering a measure that deprives liberty. The Court has held
pre-trial detention to be a precautionary and not a punitive measure121 that should be applied
