On a 4-1 vote, the Delaware Supreme Court late Monday upheld the Delaware Court of Chancery’s order to force the sale of TransPerfect Global Inc., a profitable translation-services company deadlocked by tensions between its warring owners.

The ruling followed a dramatic hearing last month, when attorneys for TransPerfect co-founder Philip R. Shawe and his mother argued, for the first time on appeal, that a 2015 ruling by Chancellor Andre G. Bouchard amounted to an unconstitutional taking of Shawe’s property.
