One of the talk programs (Olbermann? Maddow?) mentioned a few days ago, that AFTER some decision, one of the Justices..(chief justice?) was talking and said...(paraphrased) "We didn't really deal with the issue of the 'person' status of corporations ...though we just assume that they have it...."

and supposedly, a clerk overheard and wrote down his remark and passed it off as part of the decision......something like that. And it has been taken for granted ever since.
It was so weird that on the program, it was asked again...

I never did hear exactly who & when this was supposed to have occurred
