USA Today - Former Dallas Maverick Roy Tarpley filed a federal lawsuit Wednesday, claiming the NBA and the team violated the Americans with Disabilities Act by refusing to reinstate him to the league. Tarpley, who was permanently banned from the NBA in 1995, claimed in his lawsuit the NBA and the Mavericks discriminated against him on the basis of his disability as a recovering drug and alcohol abuser. "Tarpley is a qualified individual with a disability within the meaning of the ADA, in that he has a disability in the form of past drug and alcohol abuse, which substantially limits at least one of his major life activities," according to the 46-page lawsuit, which was filed in Houston federal court.</p>
