Which of the following is not considered a source of law?

Employment contracts are not considered a traditional source of law in the same way that federal law, state law, and judicial decisions are. Rather, they are specific agreements between parties that outline the terms of employment and govern the relationship within the confines of existing laws. While employment contracts are enforceable and can have legal significance, they derive their authority from broader legal frameworks, including federal and state laws that set minimum standards for employment.

In contrast, federal law constitutes legislation enacted by Congress, state law encompasses laws passed by state legislatures, and judicial decisions are interpretations and applications of the law made by courts. All of these are established sources of law that create binding guidelines and precedents within the legal system. Thus, employment contracts function within these larger legal contexts rather than serving as separate sources of law themselves.
