[Teresa Nobre, for the Communia Association] We believe that there is a minimum set of access and use rights that should be defined by public rules, since they are justified by public interests. If copyright laws do not grant to the education and research communities, the cultural heritage institutions, and the persons with disabilities the same level of protection that is granted to rightsholders, and defer to private agreements the regulation of all uses of copyrighted materials, they perpetuate an unbalanced power structure and let rightsholders weaken or undermine what should be a public policy decision.
