King & Spalding is fighting an effort to make public what lawyers at the firm said to each other about their client, General Motors, with regard to the company’s faulty ignition switch litigation.

“Plaintiffs seek to throw open the door to all of King & Spalding’s most protected opinion work-product based solely on the hope they will discover something useful inside,” the firm stated in a brief filed with the Cobb County State Court. The firm argues that fulfilling the “inappropriate” request would present a “daunting and wasteful challenge” as well as an “extreme invasion” of what should legally be confidential communication that has never been shared even with the client.
