AUSTIN, Texas (CBSDFW.COM/AP) — A federal court of appeals is hearing arguments in a lawsuit accusing the University of Texas of violating free speech rights by removing Confederate statues.

The Texas chapter of the Sons of Confederate Veterans sued after the university put three statues of leading Confederate figures in storage. The move followed 2017 white supremacist protests in Charlottesville, Virginia, in which three people died.

The lawsuit argues that the university breached its agreement with Maj. George Washington Littlefield, who donated the statues in 1921.

The 5th U.S. Circuit Court of Appeals heard oral arguments Tuesday.
