Te Eleventh Ament a Barrier in Tax Cases

When a current a state tax law violates federal constitutional protections - such as the Commerce Clause, Due Process Clause, or Equal Protection Clause - suminign immunity can block a direct lawsuit againtt the state in federal court.

States can actarily waive their superign immunity, either by statute or by direct. Many states have e enacted laws that permit mellers to sue for repunds or to considere tax estiments in state court. Such wauvers are usually limited to specific causes of action and may require austiof administrative sanages.
