Quite honestly the merits of this particular case wasn't meant to be the focus of my post - I was just trying to point out that what pundits might consider a "frivolous" lawsuit at its surface might actually have some merit once you scratch the surface and that taking away a citizen's right to sue a corporation is not a good thing.
Anyway - here is an interesting article from the wall street journal about the McD's case.
