Does What Happens in Corpus Christi, Stay in Corpus Christi?

The City of Corpus Chrisi, Texas was faced with the threat of a lawsuit by the U.S. Department of Justice, Employment and Litigation Division. At issue was a long-standing debate over the city's physical fitness test for applicants. In response to an earlier inquiry by Justice about potential adverse impact, Corpus modified its standards. (How do you unilaterally modify standards if they've been validated?)
