Morgan Stanley has been charged with using the terrorist attacks of September 11 as an excuse for failing to provide emails to both regulators and investors suing the bank in arbitrations. The bank has already paid three email-related fines this year and was sued by another securities industry watchdog.

The NASD is charging Morgan Stanley with routinely failing to provide emails in arbitration proceedings and to regulators. The regulator further alleged the bank lied about millions of emails being destroyed in the September 11 terrorist attacks on New York.
