Public policy is so much more than just the passage of laws and legislation; public policy is the government. The creation of public policy is a very long and complicated process. Public policies that start in the Legislature have to go through a complex process of which many lawyers do not understand how the legislative process works. The Executive takes the law and refines it through executive agencies which then create rules and regulations of the public policy. The Executive agencies' process of creating public policies has led to a complex web of relevant rules and regulations that are necessary to create public policy. The law is fully formed under the Judicial Branch. As a result, courts wield significant power in determining how policy affects the public. Political science studies public policy to see how the policies are created, and how different variables will influence the policies, and have developed elaborate theories on how public policy is made.
