DAVID H. WEINSTEIN, a founder of the Firm and now Senior Counsel to it, has concentrated his practice in litigating complex commercial matters.

Since 1972, Mr. Weinstein has represented clients charging some of the nation’s largest companies with violating the antitrust, commodities, consumer protection, retirement, R.I.C.O., and securities laws. He has pursued litigation in varied fields and industries, including accounting, banking, cattle and cattle futures, computers, copper, electronic components, financial instruments, healthcare, insurance, law firms, milk, motion pictures, oil and gas, propane, retirement plans, and refuse hauling and recycling.

Currently, Mr. Weinstein is court-appointed interim co-lead counsel for a class of holders of variable-rate bonds whose interest rate was linked to LIBOR, the London Interbank Offered Rate. The litigation is against the 16 banks that allegedly participated in fixing the LIBOR rate in the 2007-2010 period.

Mr. Weinstein is also court-appointed interim co-lead counsel for a class of Jewish survivors and the estates and heirs of the Jewish victims of the Holocaust in Hungary. They have sued Hungary and the Hungarian National Railways. The claims arise from the defendants’ participation in genocide.

Mr. Weinstein served as co-lead counsel in an antitrust class action involving manipulation of the propane market. In that case the court approved a $52 million settlement.

As co-lead counsel in a nationwide class action for property owners whose homes contained defective polybutylene plumbing, Mr. Weinstein achieved one of the largest property-damage class-action settlements in history. At a cost of more than $1.1 billion the defective plumbing in approximately 340,000 homes was replaced over a 15-year period.

Mr. Weinstein served on the steering committee of attorneys that recovered over $700 million for retail pharmacies in a class action charging major manufacturers and wholesalers of brand name prescription drugs with conspiring withhold discounts to retail pharmacies.

On a pro bono basis, Mr. Weinstein was court appointed sole lead counsel in complex coordinated immigration proceedings concerning more than 100 refugees seeking U.S. asylum.
