I have followed this case and others for a long time and I fully understand what is going on.
Judge Robinison ruled in favor of MU and RMBS appealed to the Federal Circuit Court and they lost. The Federal Court sent the case back to Judge Robinison for clarification of her decision.
RMBS was found guilty of spoilation/ destruction of documents that should have been preserved as RMBS was preparing litigation against MU and HYNIX. RMBS had a duty to preserve. Their actions to destroy documents hindered and prejudiced the defendants MU and HYNIX. RMBS will have to pay a price for their deception.
