resolved — Court finding of spoliation of evidence (deletion of personal Gmail account) in Williams v. Energy Transfer merger litigation

obstruction-perjury · 2016 · Delaware Court of Chancery (Vice Chancellor Sam Glasscock III); affirmed by the Delaware Supreme Court (en banc) on Oct. 10, 2023 · The Court of Chancery found that Armstrong's destruction of his personal Gmail account constituted spoliation of evidence and that his explanation (deleting it over spam concerns) was not credible. The court declined to draw an adverse inference but ordered Armstrong to pay a monetary sanction (amount not specified in the ruling) to compensate Energy Transfer for related costs. The underlying litigation was won by Armstrong's company, Williams (Energy Transfer was ordered to pay Williams a $410 million reimbursement fee plus $85 million in attorney's fees), and the Delaware Supreme Court affirmed the Chancery rulings.

During the failed 2015-2016 merger between The Williams Companies (where Armstrong was CEO) and Energy Transfer Equity (ETE), ETE accused Armstrong of using a personal Gmail account to undermine the board-supported deal and of deleting that account two days after a 2016 deposition. In its December 29, 2021 post-trial opinion, the Delaware Court of Chancery (Vice Chancellor Sam Glasscock III) found that 'Armstrong's destruction of his Gmail account was spoliation of evidence,' rejected his stated reason as not credible, and imposed a monetary sanction on Armstrong personally rather than an adverse inference. This was a formal court finding against Armstrong as an individual within a case his company ultimately won; on October 10, 2023 the Delaware Supreme Court, sitting en banc, affirmed the Court of Chancery's opinions (Energy Transfer, LP v. The Williams Companies, Inc., No. 391, 2022).
