[5] : Bouvier's Law Dictionary, Revised 6th Ed (1856)

permission. a license to do a thing; an authority to do an act which without 
such authority would have been unlawful. a permission differs from a law, it 
is a cheek upon the operations of the law. 
     2. permissions are express or implied. 1. express permissions derogate 
from something which before was forbidden, and may operate in favor of one 
or more persons, or for the performance of one or more acts, or for a longer 
or shorter time. 2. implied, are those, which arise from the fact that the 
law has not forbidden the act to be done. 3. but although permissions do not 
operate as laws, in respect of those persons in whose favor they are 
granted; yet they are laws as to others. see license.
