State District Judge William Sowder wrote the school and Leach's attorney Monday that Texas Tech didn't violate the coach's due process rights when he was fired in December 2009.
Texas Tech spokesman Chris Cook says the school is pleased with the decision. Leach's attorney Ted Liggett tells the Lubbock Avalanche-Journal (bit.ly/VBcgm2) Leach is considering options that include a court appeal.
Sowder previously dismissed most of the other counts in Leach's lawsuit.
Leach sued a month after he was fired for alleged mistreatment of a player. He denied the accusation. He was Texas Tech's most successful football coach and now coaches at Washington State.
