Breaking an unenforced law is a sin, while breaking an enforced law is a crime.
If that man or assembly that hath the sovereign power disclaim any right essential to the sovereignty, whereby there accrueth to the subject any liberty inconsistent with the sovereign power; that is to say, with the very being of a Commonwealth; if the subject shall refuse to obey the command in anything, contrary to the liberty granted, this is nevertheless a sin, and contrary to the duty of the subject: for he to take notice of what is inconsistent with the sovereignty, because it was erected by his own consent and for his own defence, and that such liberty as is inconsistent with it was granted through ignorance of the evil consequence thereof. But if he not only disobey, but also resist a public minister in the execution of it, then it is a crime, because he might have been righted, without any breach of the peace, upon complaint.
Hobbes, Lev XXVII 28
