The legal theory is the delegation of powers. Congress delegated the power to write legislation within a certain scope, breadth, and depth, to the executive branch of government, authorizing it to set up an agency to manage same.
Congress has the right to delegate its power to legislate to other branches of government. It is unfortunate, but we are learning now that it has delegated pretty much all of its power.
