A more thorough explanation: Countermand is a legal term that refers to the act of revoking, canceling, or reversing a previous order, directive, or command. It is typically used in the context of contracts, military orders, or other official instructions. Countermanding a directive effectively nullifies its original intent and replaces it with a new instruction.
Example: The judge issued an order to countermand the previous ruling and grant a new trial.
