a whole and the role of the international court is to establish whether the proceedings as a
166
whole were in accordance with international provisions.
115. Since the alleged violations of personal liberty are intimately linked to the criminal
proceedings, the Commission will first rule on the following points related to the trial: (i) the principle of
presumption of innocence, (ii) the right of defense, and (iii) the remedies filed in connection with the
criminal trial. Fourth, the Commission will address Mr. Ruano Torres’s incarceration as a consequence of
the proceedings.
1.
The principle of presumption of innocence
116.
Article 8.2 of the American Convention establishes:
Every person accused of a criminal offense has the right to be presumed innocent so long as his
guilt has not been proven according to law.
117. The right to a fair trial, established in Article 8 of the American Convention, covers all
the procedural requirements that must be observed so that persons may defend their rights adequately
against any act by the State.167 One fundamental element of those guarantees is the principle of
presumption of innocence.168
118. The Inter-American Court has said that this principle means that the defendant does not
have to prove that he did not commit the offense with which he is charged, because the onus probandi
is on those making the accusation.169 Thus, the convincing demonstration of guilt is an essential
requirement for a criminal sanction, so that the burden of proof falls on the prosecutor and not on the
accused.170 On this point, the Human Rights Committee has ruled that:
The presumption of innocence, which is fundamental to the protection of human rights,
imposes on the prosecution the burden of proving the charge, guarantees that no guilt can
be presumed until the charge has been proved beyond reasonable doubt, ensures that the
accused has the benefit of doubt, and requires that persons accused of a criminal act must
be treated in accordance with this principle. It is a duty for all public authorities to refrain
from prejudging the outcome of a trial, e.g. by abstaining from making public statements
171
affirming the guilt of the accused.
