A federal court upheld a prior dismissal of a challenge to Texas’s campus carry law Thursday, providing individuals with a concealed carry permit the ability to carry a firearm on public university property.

The U.S. Fifth Circuit Court of Appeals rejected to revive the lawsuit by three University of Texas at Austin professors, upholding a 2015 law that the trio challenged in July 2016, yet was ultimately dismissed.

The professors claimed that the aforementioned law would violate an individual’s constitutional rights of free speech, due process and equal protection and would “have a substantial chilling effect on class discussion.”

The three-judge panel rejected the assertion, arguing that there is not proof of any impending harm to rationalize such fears.
