D---TIME LIMITS. Sui generis never ending term is bad because it denies indigenous people a contemporary voice.

For these reasons, sui generis rights have been proposed for folklore. According to these proposals, protection should be perpetual and retroactive, and derivative works should be strictly controlled. But there may be consequences for the implementation of these rights. By overprotecting folklore, the public domain diminishes, which means that there are fewer works to use to build on. Therefore, indigenous artists who want to develop their artistic traditions by reinterpreting traditional motifs in non-traditional ways, and want to compete in the arts and crafts markets may be inhibited by these regimes. The consequence is that these laws may "freeze" the culture in a historic moment, allowing us to think of indigenous peoples as romantic relics from a lost time, and to deny them a contemporary voice.
