The U.S. Supreme Court justices Monday heard oral arguments in Ohio v. American Express, a case that deals with whether the credit card giant should change its supposed anti-steering practices.

Deborah White, general counsel of the Retail Industry Leaders Association and president of sister organization Retail Litigation Center, said she is hopeful that five of the justices will rule against  New York-based American Express Co. RILA and the litigation center represent the interests of some of the nation’s biggest retailers.
