The U.S. Court of Appeals for the Fifth Circuit is scheduled to hear arguments in a lawsuit challenging a campus carry policy at the University of Texas at Austin. The Fifth Circuit has jurisdiction over district courts in Louisiana, Mississippi, and Texas.

The lawsuit in question was filed more than a year ago by three U.T. professors: Jennifer Glass, Lisa Moore, and Mia Carter. A report by the Texas Tribune says the lawsuit claims that a campus carry policy at U.T., which allows concealed handguns inside most of their public university buildings, has negative effects on free speech. The school also has strict restrictions for weapons on campus, real or fake, that are not concealed.

The campus carry policy was met with protests from some students and teachers when it was passed in 2015 and went into effect in August of 2016. A District Judge dismissed the lawsuit entirely on Thursday, citing lack of evidence to support the lawsuit’s claim.

Glass, Moore, Carter, their lawyers, appealed to the 5th Circuit Court on Friday. The court will begin hearing oral arguments in the case on Wednesday, July 11. Texas Attorney General Ken Paxton, who’s been defending the campus carry law in the lawsuit and praised the District Court Judge’s decision, is expected to give arguments as well.
