The company's logo across the front of an awning marks the location of a Domino's restaurant in Chicago, Illinois.

The Supreme Court denied a petition from pizza giant Domino's on Monday to hear whether its website is required to be accessible to the disabled, leaving in place a lower court decision against the company.

The decision not to hear the case is a loss for the company and a win for disability advocates, who have argued that if businesses do not have to maintain accessible sites, disabled people could be effectively shut out of substantial portions of the economy.

The decision from the justices was announced in an order.

The case was originally brought by a blind man named Guillermo Robles, who sued the pizza chain after he was unable to order food on Domino's website and mobile app despite using screen-reading software.

Attorneys for Robles argued in court papers that the Americans with Disabilities Act requires businesses with physical locations to make their websites and other online platforms accessible to those with disabilities.
