A lawsuit accusing restaurant chain TGI Friday's violated consumer fraud laws with its drink pricing can't go ahead as a class action that could have included millions of members, but a similar case involving Carrabba's Italian Grill restaurants can, New Jersey's state Supreme Court ruled Wednesday.

Debra Dugan sued TGI Friday's after she was charged one price for a drink at the bar and a higher price at a table in 2008. The restaurant didn't list drink prices on its menus, according to the lawsuit.

A lower court in 2012 granted class-action status to anyone who ordered unpriced drinks at 14 of the company's restaurants in New Jersey from 2004 through 2014. TGI Friday's had estimated that could have amounted to as many as 14 million customers, according to court filings. But the plaintiffs disputed that figure.

According to the lawsuit, TGI Friday's conducted research that showed that customers spent an average of $1.72 less on drinks if the prices were displayed than if the prices weren't displayed. The lawsuit sought to prove that that amount could be considered a loss for anyone who had ordered a drink at the restaurants. Wednesday's 5-1 ruling rejected that argument, but said individual claims could still proceed.
