The reason why that would be drafted in that way is because it gives flexibility in the court for all the parties to negotiate what would be a reasonable timeline. It may be a small area that's being restored. It might be a significant restoration. It may be that it has to be done in a phased manner. What that provides for is negotiations within a fixed time. It allows for the court to talk to all parties in the case, as there may be additional interveners.
One thing I would add in there for the provision that you've raised there...the reason why it says “notwithstanding remedial provisions in other acts” is that these are the remedies available under clause 16, and they could relate to another law that provides for additional remedies.
