What type of laws fail to give fair warning to individuals and law enforcement as to what conduct is unlawful?​

Quizplus · Accepted Answer

Vague laws fail to give fair warning to individuals and law enforcement as to what conduct is unlawful. Ex post facto laws are those that criminalize an act that was not illegal when committed or increase the punishment for a crime after it was committed. Misdemeanor and felony laws refer to the severity of the crime and do not necessarily determine whether a law gives fair warning or not.
