We'll fight to the death about gay marriage...

...but when it comes to corporations, we know whose side the Supreme Court is on.

WASHINGTON -- The Supreme Court on Tuesday overturned the conviction of the Arthur Andersen accounting firm for destroying Enron Corp.-related documents before the energy giant's collapse.

In an unanimous opinion, justices said the former Big Five accounting firm's June 2002 conviction was improper. It said the jury instructions at trial were too vague and broad for jurors to determine correctly whether Andersen obstructed justice.
