Does pleading ignorance ever work?

Pleading ignorance rarely works as a defense for breaking the law, under the principle that "ignorance of the law is no excuse," but it can succeed in very specific, limited situations, primarily involving mistakes of fact, recently changed/unclear laws, or when a crime specifically requires knowledge of its illegality (mens rea). A genuine, reasonable mistake about a fact (e.g., taking the wrong coat, thinking it's yours) can negate criminal intent, but simply not knowing something is against the law usually isn't enough.
