The Achmea v. Slovak Republic investor-state case is illustrative of what a nightmare we are getting into and how little anything that matters to people ends up mattering (not at all) when corporations "inequal rights" become superior to democracies and people and laws and politicians and even presidents.
It all started when the Slovak Republic voted for single-payer in 2006 because they could no longer afford the insurance system.. Sound familiar?
The case shows how investment arbitral tribunals can issue huge fines, and how they cannot change laws per se but they can fine countries huge amounts until they do.

There is an earlier case between the same two parties also there. Achmea used to be named Eureko.
Note that although Slovakia officially "won" the second case, (the insurance company won the first against them) that second case's "win"
seems to have just been because the plaintiff insurance company sued them a bit too early.
