Inadvertent Receipt of Opponent Emails
Emma Erickson, counsel for Enigma Technologies, receives an email attachment containing internal strategy memos from opposing counsel at Evergreen Bank. The cover note indicates the materials were meant for the bank's own litigation team. Erickson immediately contacts the sender to alert them of the transmission and returns the files without reviewing their contents.
Preservation of Sales Records
Elliot Edmonds sues Everest Holdings for gender discrimination and requests production of all internal emails discussing his performance reviews. Everest Holdings directs its IT department to suspend routine deletion of employee mailboxes and to image the relevant custodians' hard drives within days of receiving the complaint.
Once litigation is reasonably anticipated, a party must take reasonable steps to identify and retain potentially relevant electronic data. Failure to do so can result in sanctions even if the loss occurs through ordinary business practices.
