> As the wikipedia page you yourself are citing, overturned on appeal.

So the law says "Don't do behavior X", the government takes you to court, there is a judgment, you appeal, and win the appeal.

I'm not sure "dismissed on appeal" means "this isn't working as intended".

Successful market regulation includes investigating issues, prosecuting them where there is reasonable grounds to do so and it also includes a determination (either in investigation or in court) that something is not an issue.
