The injunction says the Tlicho, in particular, because they were the primary litigant in that case, would suffer irreparable harm if those amendments were brought into force, because what it would mean is that the Tlicho, Sahtu and Gwich'in land and water boards would be dismantled. Picture staff being sent packing, corporate memory and resources and capacity being disbanded, and the single Mackenzie Valley Land and Water Board being created.
The irreparable harm is at that institutional bureaucratic capacity level, and it would take a lot to get that engine going again if the court result was ultimately favourable and was in line with the findings of Justice Shaner, I believe, in the injunction case.
In other words, depending on what level of court this stopped at, if the result was, yes, indeed, this is an unconstitutional set of amendments that go against land claim agreements, then you would have to restart these boards years from now, which would just be lost time and waste and uncertainty.
