Background
Computer Sciences Corporation (CSC) brought a trade-secret lawsuit against Tata Consultancy Services (TCS), one of India’s largest IT outsourcing companies, after discovering that TCS had used confidential access — obtained through a legitimate consulting engagement at Transamerica — to copy CSC’s proprietary life-insurance administration software platforms, known as Vantage and CyberLife. TCS then used the stolen trade-secret knowledge to build a competing platform called BaNCS, which it marketed to Transamerica itself, eventually landing a $2.6 billion contract that displaced CSC.
A jury found TCS liable and awarded $56 million in compensatory damages and $112 million in punitive damages — a 2:1 punitive-to-compensatory ratio. The Fifth Circuit affirmed in November 2025. TCS petitioned the Supreme Court, raising two significant legal questions under the Defend Trade Secrets Act (DTSA).
The Court’s Holding
The Supreme Court denied certiorari on June 15, 2026, allowing the Fifth Circuit’s $168 million judgment to stand. The Court issued no written opinion explaining the denial, as is standard for cert. denials.
TCS had pressed two questions that the lower court’s ruling left open: (1) whether the DTSA permits a plaintiff to recover for the defendant’s unjust enrichment without proving the plaintiff suffered a quantifiable monetary loss; and (2) whether a 2:1 punitive-to-compensatory damages ratio violates due process when compensatory damages are already substantial. The Supreme Court’s silence on both questions leaves those issues for future litigation.
Key Takeaways
- A cert. denial is not a ruling on the merits — the Supreme Court is not saying TCS’s legal arguments are wrong, only that it will not take the case at this time. The questions TCS raised remain open circuit questions.
- The unjust-enrichment measure of trade-secret damages under DTSA — allowing recovery of a defendant’s profits even when the plaintiff cannot quantify its own loss — remains viable in the Fifth Circuit and has now survived one Supreme Court review opportunity.
- A 2:1 punitive-to-compensatory ratio in a substantial trade-secret verdict survived both the Fifth Circuit and the cert. stage, though this question remains unsettled in other circuits.
- For corporate IT and outsourcing relationships, the case underscores that access to a client’s proprietary systems creates legal obligations that survive the engagement: TCS was liable not just for taking documents, but for using client confidences to win business against that client.
Why It Matters
The $168 million judgment is one of the largest trade-secret verdicts in recent memory, and TCS’s failed cert. petition means the award stands. For the IT outsourcing industry — where vendors routinely gain deep access to clients’ proprietary systems and data — the case is a stark reminder of the legal risk that accompanies that access. A vendor that uses knowledge gained from one client engagement to compete against that client has crossed from legitimate business development into trade-secret misappropriation.
The unresolved legal questions TCS raised (unjust enrichment without proven loss; the permissible punitive multiplier) will likely surface in future DTSA litigation. Until the Supreme Court addresses them, trade-secret defendants in the Fifth Circuit face exposure to unjust-enrichment damages even when the plaintiff’s own losses are hard to measure, and punitive awards at 2:1 or higher remain a real risk in egregious cases.
