In Arthur Andersen LLP V

In Arthur Andersen LLP v. United States, Andersen's previous conviction was overturned by the Supreme Court because it was determined that:

A) the trial court's jury instructions were defective.
B) the government had not met its burden of proof.
C) Andersen was acting solely on Enron's directions and that only Enron could be held responsible.
D) no law existed at the time that Andersen acted that prohibited the shredding of corporate documents and that such law was passed after the scandal and could not be enforced retroactively.
