The other pages in this part talk about the four main types of laws. There are a few other types of law. Executive orders are given by the president or governor to an administrative agency. They have the full binding force of law. Treaties are legal written agreements between two or more nations. Treaties are governed by international law. In the U.S., only the president or members of the executive branch can make treaties. Attorney General opinions are issued by both the U.S. and the Louisiana state attorney generals. Attorney General opinions are written interpretations of existing law. They cannot create new law. Though they are considered important by courts, they are not the final say. Municipal ordinances are passed by local municipalities like cities or towns. They have the full force and effect of law.
