It would be the standard outcome, yes.

True but not necessarily fully accurate. The court has limits on recoverable legal fees and what they assess is often only about a 1/3 to 1/2 of what a party may have actually spent on legal fees.

The Supreme Court, though? I’m pretty certain the costs will be covered by the party that loses.

In my experience the legal costs that are recoverable have been a fraction of what I actually spent on lawyers.

I think in this case the costs will be recovered by the parties.

Perhaps PPPDev can confirm if they actually got 100% cost recovery? As I said, I have never seen this happen as the costs that are recoverable are generally at the discretion of the court and in most cases well below what was actually spent by the prevailing party. This is especially true in cases where the loosing party can claim they represent the public good as this plaintiff attempted to argue.
