Unenforced law
An unenforced law (also symbolic law, dead letter law) is a law which is formally in effect (de jure), but is usually (de facto) not penalized by a jurisdiction. Such laws are usually ignored by law enforcement, and therefore there are few or no practical consequences for breaking them. The existence of unenforced laws has been criticized for undermining the legal system in general, as such laws may be selectively enforced.
