If the government were to remove the clauses respecting the broad discretion of the minister, there is still an onus on community governments, chiefs and councils, to take this to the community by way of a referendum. This would be necessary to meet the threshold of free, prior, and informed consent of the people who are most affected by the implications of continuing in an Indian Act structure.
With that said, I think it does become a little more palatable if you remove that broad discretion of the minister.
