    Excessive or unauthorized collection by an officer.

  • Black's Law Dictionary: 2nd Edition

    The wrongful act of an officer or other person in compelling payment of a fee or reward for his services, under color of his official authority, where no payment is due. Between "extortion" and "exaction" there is this difference: that in the former case the officer extorts more than his due, when something is due to him; in the latter, he exacts what is not his due, when there is nothing due to him. Co. Litt. 368.
