Attorneys from Gibson, Dunn & Crutcher and Wachtell, Lipton, Rosen & Katz sparred this week over whether information related to an internal investigation of a former CEO of the dating app Tinder should be unsealed in Manhattan Supreme Court’s Commercial Division.

The Gibson Dunn team represents Tinder founder Sean Rad and some of his early employees, who say they are owed $2 billion or more by the defendants IAC and its subsidiary, Match, for their alleged undervaluation of Tinder. Wachtell represents the defendants in the suit, which was filed in 2018 and is set to go to trial in November.
