I believe it's section 18 of the current act. At the time when the tapes were made, decades and decades ago, it may have been a different section.
It is a right that I think in some instances makes a lot of sense. The recordists would own and control the things that they record.
In this case, what it allowed was the appropriation of these stories, myths, and legends from this community, and so it wasn't an appropriate application of that rule. In terms of specific things to pinpoint, where indigenous concerns could be brought in, maybe it's that section 18.
