I have sat and heard soooooooooo many lawsuits that are frivilous that I keep swearing I am going to go through them and see if I can incorprate a few of them into one lawsuit.
Having said that, let me add, that there are tons of these suits clogging the court systems all over the country. I hold completely guilty those inept, anything for a fee, attorneys that keep these things flying.
My recommendation for frivilous suits would be to take the lawyer and his clients outside the courthouse and immediately execute them. Then put their case at the end of the yearly docket... when no one shows, dismiss it.
