The Delaware Court of Chancery has approved the $770 million sale of TransPerfect Global Inc. to co-founder and CEO Philip R. Shawe, rejecting a bid from his rival to unravel the deal and bringing nearly four years of fierce litigation to the verge of its final resolution.

In a 70-page memorandum opinion, Chancellor Andre G. Bouchard on Thursday accepted a court-appointed custodian’s recommendation that Shawe acquire all of Elizabeth Elting’s shares in a company the pair launched from a college dorm room in 1992. The ruling gives Shawe full control over the translation-services firm and finally breaks the corporate deadlock that led Elting to petition for TransPerfect’s breakup in 2014.
