hint: it's the "proving your case" part. in this scenario, the parties rarely go to trial or arbitration.
i don't really need a basis for a case, just a basis for a threat. 'rattling the sabres', so to speak. it's sad, but true.
By "this sort of thing", do you mean an equity dispute? No, I haven't.
But as someone part of running a mid-size company, I have been party to being threatened by baseless accusations. Guess what happens when there is "no basis for a case"? Nothing. Nada. Zip. Business as usual.
So, judging by your comment that you "don't really need a basis for a case", I can assume that you haven't been through this, either. But, if you're curious, go ahead and try to sue someone with no basis for a case, and see how the system deals with you.
