The Delaware Court of Chancery on Tuesday denied Virginia-based information technology firm Computer Sciences Corp.’s bid to recoup about $18 million it had paid for an executive to defend against criminal investigations into an alleged bribery scheme stemming from the company’s purchase of ServiceMesh Inc. in 2013.

Chancellor Andre G. Bouchard said in a 10-page letter opinion that the request by Computer Sciences, or CSC, for indemnification was “unreasonable” under the terms of its equity purchase agreement to acquire ServiceMesh for $260 million.
