A Delaware jury has returned a $3 million verdict in a whistleblower suit against Overstock.com, finding after just one hour of deliberation that the online retailer had avoided reporting abandoned gift card balances to state officials.

The verdict, which followed a six-day trial, is likely to lead to an automatic trebling of damages, plus an award of attorney fees, bringing Overstock’s potential liability to as much as $10 million in the four-and-a-half year-old case, an attorney for whistle blower William Sean French said on Monday.
