As a result of the final approval of what is commonly known as the Show Me Your Papers Law, or SB 4,  signed into effect by Texas Governor Greg Abbott on May 7, 2017, a group of law enforcement officials, cities, and counties have filed a federal lawsuit against the State of Texas in the United States District Court for the Western District of Texas, San Antonio Division. 

AUSTIN, Texas (AP) — The Texas attorney general has filed suit against Austin, accusing the state capital of violating "open carry" rules by banning guns inside city hall.

Republican Ken Paxton said in a statement Thursday that Austin's municipal building is violating a law approved last year that allowed licensed Texans to openly carry handguns.
