5 which they are parties.” 4 Therefore, the States must ensure that the rulings set out in the decisions of the Court are implemented at the domestic level. 5 4. That the obligation to comply with the decisions of the Court’s judgments conforms to a basic principle of the international responsibility of the State, supported by international case law, according to which a State must comply with its international treaty obligations in good faith (pacta sunt servanda). 6 The treaty obligations of States Parties are binding on all the States’ powers and organs. 7 5. That the States Parties to the Convention must ensure compliance with its provisions and their inherent effects (effet utile) within their respective domestic legal systems. This principle applies not only in connection with the substantive provisions of human rights treaties (i.e. those dealing with the protected rights) but also in connection with procedural rules, such as the ones concerning compliance with the decisions of the Court. Such obligations are intended to be interpreted and enforced in a manner such that the protected guarantee is truly practical and effective, taking into account the special nature of human rights treaties. 8 6. That according to the operative paragraph three of the Judgment on the merits (supra Having Seen clause 1) and two of the Judgment on the reparations (supra Having Seen clause 2), the State must, inter alia, investigate the facts of the case at hand, identify and, if applicable, punish the responsible and adopt all measures in its domestic law that are necessary to comply with this obligation; of which it will inform the Court, semiannually, until the end of the corresponding actions. 7. That, in the Order issued by the Court on November 27, 2003 (supra Having Seen clause 4), the Court verified that the State complied with the payment of the compensation ordered by the Court in favor of the following next of kin of the victim: Richard Blake, Mary Blake, Richard Blake Jr. and Samuel Blake (Operative Paragraph two of the Judgment on the reparations of January 22, 1999).
