The Permanent Forum notes with appreciation the establishment of a Voluntary Fund by WIPO to enable the participation of indigenous representatives in the work of the WIPO Intergovernmental Committee on traditional knowledge and traditional cultural expressions, and encourages donors to contribute to the Trust Fund. 172. The Permanent Forum, taking into account the recommendation of the International Technical Workshop on Indigenous Traditional Knowledge (E/C.19/2006/2, para. 41) regarding a study on customary laws pertaining to indigenous traditional knowledge, decides to appoint Michael Dodson as Special Rapporteur charged with preparing, within existing resources, a concept paper on the scope of the study that would investigate to what extent such customary laws should be reflected in international and national standards addressing traditional knowledge, and requests the Special Rapporteur to report to the Permanent Forum at its sixth session on this matter. The study would include an analysis of indigenous customary law as a potential sui generis system for protecting indigenous traditional knowledge. Relevant organizations of the system should collaborate to promote respect for and recognition of the customary legal systems of indigenous populations pertaining to indigenous knowledge in national legislation and policies as well as with regard to their application. 26
