Yes. I think the language you are referring to is maybe some of the right to regulate clauses that Canada has started to put into agreements like the CETA and its model investment treaty from 2021. Those, I would say, are completely untested. We haven't seen cases under those agreements because they're not in force yet.
There is a book that came out a few years ago now that looked into modern language in some of the more modern treaties that Canada has been pursuing in other countries as well that tries to strengthen right to regulate provisions. It has not been highly effective. In ISDS, panels will use older treaties as a basis for the standards that these investors have in other countries. That's one of the reasons. You get these new treaties, but the decisions are being based on older reasoning.
