Gov't Code Section 2.104
(a)Any citizen residing in the jurisdiction of an entity described by Section 2.101 (Applicability) may file a complaint with the attorney general if the citizen offers evidence to support an allegation that the entity has adopted a rule, order, ordinance, or policy under which the entity enforces a federal law described by Section 2.102 (State and Local Government Policy Regarding Enforcement of Federal Firearm Laws)(a) or that the entity, by consistent action, allows the enforcement of a federal law described by Section 2.102 (State and Local Government Policy Regarding Enforcement of Federal Firearm Laws)(a). The citizen must include with the complaint any evidence the citizen has in support of the complaint.

The attorney general may recover reasonable expenses incurred obtaining relief under this subsection, including court costs, reasonable attorney’s fees, investigative costs, witness fees, and deposition costs.
