So I'm watching The Incredibles right now and it has got me wondering if anything like mass super hero law suits has ever happened in DC before I thought about posting this question in Marvel but I'm sure it's been done before especially since Daredevil and She-Hulk are lawyers however when it comes to DC I can't think of any lawyers but I can see Lex Luthor pulling something like that with Superman to get rid of him.
This is essentially the scene I'm talking about.
