“Any law or other act that contradicts the Constitution shall be invalid. Only laws that are published shall be valid. Ignorance of the law shall exempt no one from liability.”
Three rules are set here: any law or other act that contradicts the Constitution is invalid; only laws that have been published are valid; and ignorance of the law does not exempt anyone from liability.
A driver who breaks traffic rules cannot avoid a fine by saying they did not know the rules. At the same time, they can only be penalised under a law that was officially published.
All three rules are common exam questions. Pay special attention to: only published laws are valid, and ignorance of the law is no excuse.
