15. The Court also took into account that Article 29 of the American Convention on the "Norms of Interpretation" provides clear hermeneutical guidelines such that the interpretation of the Convention cannot be done in a way that: a) allow[s] a State Party, group or person to suppress the enjoyment or exercise of rights and freedoms recognized in this Convention or restrict them more than the manner provided for in the Convention; b) limit[s] the enjoyment or exercise of any right or freedom recognized pursuant to the laws of any State Party or pursuant to any another convention that the States form part of; c) exclud[es] other rights or guarantees that are inherent to the human being or that are derived from a representative democratic form of government; d) exclud[es] or limit[s] the effect produced by the American Declaration of the Rights and Duties of Man, and other international acts of the same nature. 16.

In exercising its jurisdiction to interpret procedural provisions of the American Convention, the Court has adopted fundamental decisions for the inter-American system.
