That's a good question. It removes the burden on indigenous peoples. Every time we decide to introduce a bill, we have to emphasize that a non-derogation clause must be included. This bill removes that burden.
It also gives force to the Constitution, since this provision will apply in every interpretation of our laws, especially in the case of a judicial review or a dispute where the judge must assess a bill. The purpose of this bill is to properly guide the choice of interpretation that protects indigenous rights.
