the private sector.37 In light of this obligation, once the State authorities have
knowledge of the facts, they must initiate, ex oficio and without delay, a serious,
impartial, and effective investigation.38 This investigation must be carried out in all of
the available legal venues and be aimed at determining the truth.
33.
In addition, the obligation pursuant to international law to prosecute, and if
criminal responsibility is determined, punish the perpetrators of human rights
violations, stems from the obligation to guarantee rights enshrined in Article 1(1) of
the American Convention. This obligation implies the obligation of States Parties to
organize their governmental apparatus, and in general, all of the structures in which
public power is manifested, in a way that assures individuals the free and full
exercise of their human rights. 39 As a consequence of this obligation, the States
must prevent, investigate, and punish all violations to the human rights enshrined in
the Convention, and also, seek the reestablishment, if it is possible, of the violated
right, and where applicable, the reparation of the harm produced given the violation
of the human rights. 40 If the State’s apparatus functions in a way that assures the
matter remains in impunity, and it does not restore, in as much as is possible, the
victim’s rights, it can be ascertained that the State has not complied with the
obligation to guarantee the free and full exercise of those persons within its
jurisdiction. 41

For its part, universal and regional bodies for the protection of human rights
have ruled on the scope of the obligation of due diligence in the investigation of
crimes related to acts of torture and the effects that this has on the analysis of the
statute of limitations.
35.
In this regard, the European Court of Human Rights has noted that when a
State official has been accused of crimes related to torture or cruel and inhumane
treatment, it is of the highest importance, in what pertains to an effective remedy,
that the criminal procedures which refer to crimes, such as torture, that imply
serious violations of human rights not be obstructed by limitations such as the
statute of limitations or allow amnesties in this regard. 42
