Well this should make their play against Perry interesting:
In State v. Hanson (Tex. Ct. App. 1994), the court held that "coercion of a lawful act by a threat of lawful action is protected free expression." The state alleged that [County Judge Regina Hanson] intentionally and knowingly threatened to terminate the countys funding of the salaries of a deputy district clerk and an assistant district attorney in an attempt to coerce the district judge into firing the county auditor and the county attorney into revoking a misdemeanants probation.
