Caselaw Caselaw is the body of law that evolves from state and federal decisions. Special education decisions can be appealed to state or federal court. Decisions issued by state court judges can be appealed to higher state courts. In most states, the highest state court is the state's own Supreme Court. Decisions by U.S. District Court judges can be appealed to the U.S. Court of Appeals for that geographical area.
Law is always subject to different interpretations.
When you read the statute and the regulations, you will develop your interpretation of the law and the impact it is likely to have on your issue. Law is affected by perceptions. Black is white, white is black. Truth is in shades of gray. This is the nature of law.
