Constitutional and administrative laws are two separate legal systems that play a critical role in the U.S. legal system, but which also have some distinct differences. Constitutional law is the body of law that establishes and governs the basic framework for how a government works, while administrative law is the body of rules and regulations created by an executive branch agency to implement specific policies or programs. Although both are important components of our legal system, there are key areas where constitutional and administrative laws diverge.

To begin with, constitutional law creates our basic governmental structure including separation of powers between three branches — legislative, judicial and executive — while administrative law focuses on the implementation of specific laws enacted by Congress or state legislatures within this structure. Furthermore, whereas constitutional law requires action from at least two different branches to be amended or repealed (i.e., Congress must pass legislation amending it), administrative agencies can issue new rules independently without any external approval required beforehand; these new rules can only be challenged afterwards via appeals processes within the court system if they are deemed to exceed their statutory authority as established by Congress or state legislatures.
