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.
