AZ HB2609

Allows taxpaying residents of Arizona to sue state or federal officials in superior court who enforce federal laws, grants, or regulations that violate the U.S. Constitution by displacing state powers traditionally reserved to states.

Permits prevailing taxpayers to recover equitable remedies including injunctive or declaratory relief, plus costs, litigation expenses, and attorney fees from losing parties.

Requires initial pleadings to establish taxpayer standing, assert no federal court jurisdiction exists, object to removal to federal court, and consent to U.S. Supreme Court appellate jurisdiction.

Specifies that defendants must be responsible for spending state or federal funds enforcing federal requirements that infringe on 13 enumerated traditionally reserved state powers, including local government, property regulation, criminal law enforcement, schools, and agriculture.

Limits claims to injuries based solely on government expenditure of general fund revenues to enforce the disputed federal laws, regulations, or grant conditions.
