Dallas is the sixth Texas city the attorney general has sued this year over marijuana decriminalization measures that he says conflicts with state law.

Texas Attorney General Ken Paxton has sued the city of Dallas over a ballot measure that decriminalizes possession of small amounts of marijuana, arguing it violates state law.

Dallas passed the charter amendment known as Proposition R, which decriminalizes possession of less than four ounces of marijuana. It also prevents police from using the odor of marijuana to establish probable cause to search people without a warrant.
