The International Covenant on Civil
Why this is right
This seems great! It's a very weak idea, because it's just saying that something within this document is relevant to recognizing common-law indigenous rights. We heard about this Covenant in P3, in the context of Australia recognizing common-law indigenous rights. The second to last sentence of P3 spells out our support for this answer: In recognizing the existence of common-law indigenous rights, the court cited Australia's obligations under the Covenant. Clearly, from that sentence, the court thinks that some language in the covenant expresses an obligation that is relevant to common-law indigenous rights.
