Robert James Provan (September 14, 1944 – July 6, 2006) was an attorney at law who practiced in Texas and is most noted for his bringing the first lawsuit of its kind in the United States against an HMO on behalf of physician's using the Americans with Disabilities Act of 1990 that the Wall Street Journal said was poised to become a major test case[1] and whose rulings have been cited in other cases.
