In a constitutional compliance review arising from Robinson-Superior Treaty augmentation litigation, the moving parties challenged both the Crown's engagement process and the compensation amount set after negotiations failed.

The court held that although aspects of engagement, including late disclosure of reliance on per-capita benchmarking against a related treaty settlement, caused serious relational harm, the reviewing role required deference to a range of honourable discretionary outcomes.

Applying a sui generis review framework grounded in honour of the Crown and reconciliatory justice, the court concluded the Crown's ultimate compensation determination of $3.6 billion plus agreed costs was justified in the legal and factual context.

The court therefore declined to intervene in the compensation decision while also addressing allocation issues between federal and provincial Crown responsibility in the reasons.

The plaintiffs brought a motion on consent to place the action in abeyance pursuant to s. 106 of the Courts of Justice Act.

The action involves complex issues of Aboriginal title relating to water and floodplains in Southern Ontario, which are also being addressed in a separate proceeding.

The court agreed that it would be disproportionate and inefficient to advance this action concurrently and ordered the matter placed in abeyance.
