The Delaware Supreme Court said Tuesday that it plans to reach a decision in April on Elizabeth Elting’s challenge to the Delaware Court of Chancery-ordered sale of TransPerfect to her rival on the company’s board.

In a two-page order, Chief Judge Leo E. Strine Jr. granted Elting’s motion to expedite her appeal, after Chancellor Andre G. Bouchard earlier this month approved the $770 million sale of the profitable translation-services company to co-founder and CEO Philip R. Shawe.
