There's so much in there that's fascinating that I shan't attempt to summarize it. I'll just give you a snippet from the last paragraph of Justice Robie's dissent to whet your appetite:
"Finally, I also cannot agree that any remand be before the same trial judge, who I
believe was manifestly biased and did not provide a fair and impartial forum for litigation
of an enormously important case with vast ramifications beyond the facts of this
proceeding. The conduct of the trial court in making the Cottle ruling, granting judgment on the pleadings and then issuing postjudgment terminating sanctions were not the
actions of a fair and impartial judge."
Come on. You gotta read the whole thing, right?!
