When something is not authorized, it means you do not have permission to do it. Retroactive authorization, however, means something was authorized after you already did it. If you appeal for retroactive authorization, you are asking the powers in charge to authorize an action you already took.

Determine the action you have taken is worthy of being authorized. There are several ways to do this -- if the action was illegal when you did it but is legal now, it might be worthy. If the action was illegal or unauthorized but you did it for a good reason, it also might be worthy of being authorized.

Contact the persons or group that deemed your action unauthorized, because they will also be the persons or group with the power to provide you with retroactive authorization. Ask what the appeal process is.

Fill out any forms, send any letters, or participate in any discussions required to show why your action should be retroactively authorized. This appeals process will be different depending on what it is you would like to have authorized and the outcome of your unauthorized action.
