There are several decisions from the Supreme Court now that suggest a communal right implies a right to manage the right—sort of an implicit right to self-government. In Tsilhqot'in, the Supreme Court referenced that in relation to aboriginal title, but even in Marshall II, the Supreme Court talked about how these were collective rights.
In fact, there is the case that I argued in New Brunswick in the Court of Appeal in 2017, where the court there specifically said that the “nature of communal rights mandates that the community regulate, or authorize, appropriate exercise of these rights by its individual members through ensuring equitable access to...resources.”
So, there's a management right implicit in the communal.
