ignorance of law

Not knowing rules

Ignorance of law is the state of not knowing that a particular act is illegal.

The legal principle that ignorance of the law is no excuse—*ignorantia legis neminem excusat*—means you can be prosecuted even if you genuinely didn't know your conduct was criminal: His ignorance of the law didn't save him from the fine.

The doctrine assumes citizens have a duty to know the laws that govern them, though critics note the impossibility of knowing every statute on the books.
