WASHINGTON (Reuters) - The U.S. Supreme Court on Monday sided with American Express Co and against 11 states, ruling that the company's policy of forbidding merchants from encouraging customers to use rival credit cards with lower fees does not violate federal antitrust law.
Handing American Express an important legal victory that validated a key component of its business model, the justices upheld a lower court decision that had cleared the company of unlawfully stifling competition through so-called anti-steering provisions in its contracts with merchants.
The decision was 5-4, with the court's conservative justices in the majority and liberals dissenting. Major retailers panned it as bad for consumers.
After the ruling, shares of American Express were up 1 percent in late afternoon trading. Shares of rivals Visa Inc and Mastercard Inc both fell, with Visa down 3.8 percent and Mastercard off 3.6 percent.
So-called swipe fees paid to credit card companies each time a consumer uses a card for a purchase are a major expense for merchants who annually pay more than $50 billion to process such transactions. New York-based American Express charges merchants higher fees relative to the other credit card networks.
The business model of American Express depends primarily on merchant fees, while competitors like Visa and MasterCard derive most of their revenues from interest on unpaid balances. American Express has said these fees fund the additional benefits it offers its cardholders compared to its rivals.
The case involved an appeal by the 11 states - Iowa, Connecticut, Idaho, Illinois, Maryland, Michigan, Montana, Ohio, Rhode Island, Utah and Vermont - of a 2016 ruling by the New York-based 2nd U.S. Circuit Court of Appeals that favored American Express.
The states, backed by President Donald Trump's administration, had argued that anti-steering provisions kept fees artificially high, leading to higher retail prices even for people who do not use credit cards.
'LOSS FOR CONSUMERS'
The Retail Industry Leaders Association, which represents major retailers including Walmart Inc, Home Depot and Target Corp, said the decision will allow American Express to continue to prevent consumers from understanding rising credit card fees.
"Today's decision is a loss for American consumers," the group's general counsel Deborah White said. "Competition in the credit card space is sorely lacking."
American Express accounts for about 26 percent of all U.S. credit card transactions.
"This was a long battle, but well worth the fight because important issues were at stake: consumer choice, fair market competition, and the ability to deliver innovative products and services to our customers, both consumers and merchants," American Express Chief Executive Stephen Squeri said.
As a result of advertising campaigns in the 1980s by Visa and MasterCard aimed at convincing merchants and consumers to use cards with lower fees, American Express tightened contract provisions with merchants to stop what it called discrimination against its cards.
Writing for the court's majority, Justice Clarence Thomas said in the "two-sided" market for credit card transactions, the states failed to show that the American Express system reduced the number of transactions or increased costs beyond a competitive level.
Liberal Justice Stephen Breyer read his dissent from the bench, underscoring the seriousness of the issue. Antitrust laws protect the economy from monopolies, Breyer said.
"I fear that today's decision will weaken this protection by departing from basic, established antitrust principles," Breyer added.
The legal issue centered on how courts find antitrust violations where limits on competition for one side might offer benefits for the other.
The decision could make it harder to find antitrust violations in markets in which businesses cater to two groups at the same time, in this case merchants and cardholders. That dynamic is common in other industries such as advertising and internet commerce, for example an online reservation platform used by both diners and restaurants.
The case began in 2010 when the U.S. Justice Department, joined by a group of states, sued American Express claiming the anti-steering contract requirements prevent merchants from using competition to try to keep credit card fees from increasing.
Visa and MasterCard settled similar lawsuits in 2010 by agreeing to change their rules.
The Justice Department declined to comment on the ruling.
