Reuters and Law360 Report on Brewer Client's Lawsuit for Unpaid Legal Fees
January 9, 2026 — Reuters and Law360 today report that Brewer client Williams Simons & Landis PC (WSL) is "suing a group of its former clients, saying they breached a representation contract by failing to pay more than $11 million owed to the firm after a successful trade secrets suit against Walmart," the Law360 report states.
The lawsuit, filed in the United States District Court for the Western District of Texas, Austin Division, names RiskOn International, its predecessor Ecoark Inc., Zest Labs Holdings, and law firm Bartko Pavia LLP as defendants.
As reported, WSL alleges it was retained under written engagement agreements to prosecute high-stakes trade-secret litigation against Walmart on a hybrid and contingent-fee basis. In 2021, WSL secured a staggering $115 million jury verdict. According to the complaint, WSL also built the litigation record that later supported a retrial verdict of approximately $223 million and culminated in an August 2025 confidential settlement.
The Law 360 report states, "Despite these victories, and the eventual settlement, triggering the contingency fee agreements, WSL said that its former clients refused to pay for its work and instead fabricated negligence claims to justify the non-payment."
"Williams Simons & Landis delivered extraordinary results in the Walmart litigation — and the firm's advocacy was the foundation for two jury verdicts totaling more than $325 million," said William A. Brewer III, partner at Brewer, Attorneys & Counselors and counsel to WSL. "The record reflects that a retrial was ordered so additional evidence could be considered. The retrial relied on the same trial record WSL developed and resulted in an even larger verdict. This dispute isn't about performance; it's about payment."
Reuters reports that Zest Labs subsequently filed a separate lawsuit on January 8, 2026, against WSL in state court in connection with the Walmart litigation.
Brewer told Reuters that WSL delivered "extraordinary results" in the Walmart case and that Zest's lawsuit was "nothing more than an attempt to deflect from paying our client."
