The AARP filed a lawsuit in federal court in Washington on Monday seeking to enjoin final rules for workplace wellness programs recently issued by the Equal Employment Opportunity Commission, claiming they allow employers to illegally access private health information of employees and use the data in a potentially discriminatory manner.

The AARP, which represents almost 38 million people age 50 or older, alleges that the rules, which the commission finalized in May, violate the Americans With Disabilities Act and the Genetic Information Nondiscrimination Act.
