De Facto Control Wins: NY Court Rejects ‘Not My Account’ Defense in Trading Case
Court Slaps Down Trader’s “Not My Account” Defense
New York’s Appellate Division just told a commodities trader he can’t dodge liability by claiming his brother-in-law’s account wasn’t his. In a terse but decisive ruling, the court held that Tauber controlled the account, traded it aggressively, and must answer for the losses Regal Commodities says it suffered.
The fight started when Regal sued Tauber to recover margin shortfalls after a series of high-volume trades blew up. Tauber argued he was merely “helping out” a relative and shouldn’t be on the hook for money he never formally received. Lower courts bought the story and tossed the case, but the appellate panel reversed, finding enough evidence of Tauber’s day-to-day control—log-ins, trade instructions, and profit draws—to treat him as the real party in interest. The judges reinstated Regal’s contract and unjust-enrichment claims, sending the dispute back for trial.
The decision is narrow on paper yet loud in practice. New York courts now have fresh precedent that “informal” trading arrangements won’t shield market participants from exchange or brokerage claims when behavior shows de-facto ownership. That matters because crypto-native traders often move size through friends-and-family accounts, OTC desks, or DeFi “vault operators” without on-chain attribution.
For exchanges and prime brokers, the ruling tightens the net around hidden leverage. If a court can pierce informal delegation, stablecoin issuers and DeFi protocols that let one wallet direct another’s margin could face similar theories if counterparties default. Regulators watching the case will likely cite it when arguing that “code is law” doesn’t erase common-law liability for economic control.
Traders who route size through proxies just lost another layer of plausible deniability; expect tighter KYC at OTC desks and louder demands for personal guarantees.
