EXACTION, torts. A willful wrong done by an officer, or by one who, under color of his office, takes more fee or pay for his services than what the law allows. 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. Wishard; Co. Litt. 368.
