Chapter Four includes a series of guarantees for fundamental rights. Section 53 limits the regulation of all rights in Chapter Two and Chapter Three to statutory law, which excludes administrative regulation ("reglamentos"). These statutes must respect the essential content of said rights. The fundamental rights and public freedoms included in Section One of Chapter Two can be invoked directly, and they ought to be regulated by means of Organic Law (which ensures greater political consensus). The creation of this statute cannot be delegated to the executive power.
