reparation

(general) Repairing or keeping in repair.
(ethics/law) The making of amends or giving satisfaction to a wronged party.
(logistics) A compensation paid by a carrier to a shipper that has been overcharged.
(U.S. law) Compensation ordered by the Interstate Commerce Commission (ICC) in situations where a carrier (specifically a railroad) has charged a shipper more than is allowable by law.
Reparation claims are differentiated from overcharge claims in that they refer to an illegal amount being charged as opposed to a legal charge: the overcharge.
