DeRolph v. State is a landmark case in Ohio constitutional law in which the Supreme Court of Ohio ruled that the state's method for funding public education was unconstitutional. On March 24, 1997, the Supreme Court of Ohio ruled in a 4–3 decision that the state funding system "fails to provide for a thorough and efficient system of common schools," as required by the Ohio Constitution, and directed the state to find a remedy. The court would look at the case several times over the next 12 years before it relinquished jurisdiction, but the underlying problems with the school funding system remain to this day.
