A Legislative Decree is a type of law enacted by a government authority, typically in situations where immediate action is needed. It allows the executive branch to create laws without going through the usual legislative process, often used during emergencies or to implement specific policies quickly. These decrees usually have a limited duration and must be approved by the legislative body, such as a parliament or congress, within a certain timeframe to remain in effect. This mechanism helps streamline governance while ensuring that elected representatives still have a say in the law-making process.
