The fallout over Manny M. Aragon’s controversial presidency at New Mexico Highlands University continues even a month after his resignation. Earlier this week, a former assistant professor of chemistry sued Highlands, arguing that he had been denied tenure because he is not Hispanic, the Associated Press reported.

David Wiedenfeld, who now teaches at Marshall University, in West Virginia, was one of four white professors denied tenure in 2005. In his lawsuit he alleges that “because of a decision made by President Aragon to engage in an illegal program to discriminate against non-Hispanic faculty and staff, Dr. Wiedenfeld was denied tenure and was forced to leave New Mexico to find work elsewhere.” In an unusual twist, Mr. Wiedenfeld also contends that he was discriminated against because administrators thought he was Jewish. He isn’t.

Two months ago, the American Association of University Professors censured the Highlands administration (The Chronicle, June 12), in large part because of the treatment of Mr. Wiedenfeld and another professor, Gregg H. Turner, who was also denied tenure and filed a lawsuit.

A month later, Mr. Aragon resigned, ending a two-year run in which he repeatedly battled with faculty members (The Chronicle, July 21). The university then settled with Mr. Turner, reportedly for $170,000 (The Chronicle, July 27).
