In addition to trying to influence legislative and administrative officials, groups can sometimes achieve their policy goals through the court system. Groups can sue other groups and individuals, demanding that they either take a certain action or that they desist from a specific action. Governmental organizations on all levels can be sued for non-compliance with the law or with their own charters.

This strategy can be very expensive and is best suited to those groups and interests with substantial financial resources, particularly if legal opponents are companies or business associations with extensive resources to pay legal costs. Such well funded groups are also often able to make substantial contributions to Texas judicial campaigns. While it is illegal to bribe a judge or to sell a favorable decision, the possibility of such misconduct has fueled concerns that campaign contributions exert inordinate influence on the rulings of Texas judges.
