That verdict, which a judge can triple to more than $5.3 billion, could upend decades-old practices that require sellers to pay commissions to buyers' brokers. March said it is unclear whether this would result in lower commissions, or delay sales while buyers' brokers negotiate with sellers. The lawsuit seeks damages for sellers of Manhattan residential property in the last four years who paid buyer brokers' commissions under REBNY rules. The case is March v. Real Estate Board of New York et al, U.S. District Court, Southern District of New York, No.
