A female law professor can keep suing The University of Texas at Austin for sex discrimination and allegedly paying her less than male colleagues, but Linda Mullenix has for the second time lost her arguments that she faced unlawful retaliation.

U.S. District Judge Lee Yeakel dismissed Mullenix’s claim that the university retaliated after the professor said it violated the Equal Pay Act. In an order on Monday, the judge ruled Mullenix did not show enough facts for the court to infer plausibly that the university retaliated against her under the EPA.
