If, by the "second suit," you mean the quo warranto, no, it is probably not huge.
Only the Attorney General of the U.S. has the right to file an action for quo warranto. If the Attorney General refuses to file suit, someone else can file it, but only if the district court in D.C. gives them permission to file. There already was one attempt to file a quo warranto suit in D.C. challenging Obama's eleigibility to hold office, and the court refused permission to file it. I doubt this attempt will fare better.
I do believe that this is what Donofrio and Pidgeon will be attempting to do.
No one has ever implied it would be easy. If its granted.... Woah.... look out.
I forgot to ask, do you know if that was tossed due to standing? I seem to remember that being the case, but honestly, I have a really bad cold and I can’t remember.
The Dealerships have standing. Thats what makes it a very different case.
