Last month a federal judge in California allowed a case by National Federation of the Blind's case to proceed, rejecting Target's argument that its Web site wasn't subject to the Americans With Disabilities Act, a 1990 law that requires retailers and other public places to make accommodations for people with disabilities. The case, which is entering a pretrial phase called discovery in U.S. District Court for the Northern District of California, could set an important precedent for applying federal accessibility law to the Internet.
