WPP moves to block disclosure of sensitive client data in ex-executive lawsuit

Former WPP executive Richard Foster has sued the advertising group, accusing it of retaliation after he raised concerns about an alleged worldwide kickback operation in its media investment division. Foster's amended complaint includes references to a Sony investigation that purportedly found WPP engaged in a rebate-withholding fraud scheme in China and other markets. WPP responded by filing a motion to seal multiple paragraphs, data tables and exhibits, asserting that the allegations are immaterial, salacious and expose highly confidential, proprietary business information such as client lists and strategic plans.

The firm also argues that Sony is not a party to the litigation and that the alleged events occurred after Foster's termination, making them irrelevant. WPP cited a 2018 confidentiality agreement signed by Foster and alleged breaches of attorney-client privilege. Lead counsel for Foster, William A. Brewer III, indicated the motion will be opposed, while both WPP and Sony declined to comment on the filings. The company plans to file an updated motion to dismiss, addressing what it calls deficiencies in the complaint.
