In accordance with domestic law, each Party shall take measures, as appropriate, with the aim of ensuring that the prior informed consent or approval and involvement of indigenous and local communities is obtained for access to genetic resources where they have the established right to grant access to such resources. These include the requirement to formulate fair and non-arbitrary rules and procedures for access, information on how to apply for PIC, the issuance of permits as evidence of PIC, the requirement to provide written decision by the competent national authority within a reasonable period of time and the like. A national competent authority must be established to implement the ABS system, where it will be possible to register ABS agreements and any other documentation that can potentially serve as evidence of PIC and MAT (Nagoya Protocol, Article 13).
