There are many things necessary to wise and useful legislation which cannot be known to the General Assembly and, therefore, must be determined outside the legislative hall. The authority of the administrative body, acting under such grant grant of power, is limited to the making of reasonable rules and regulations within the circumference of the power granted. It is difficult to define the line which separates the legislative power to make laws from administrative authority to make regulations. The question is one which has to be answered in each individual case by the judgement of the Court. The General Assembly may enact a law exercising one or more of its legislative powers, declaring the policy of the law, fixing the principles which are to control in given cases, and, at the same time, delegate to an administrative body the power to ascertain the facts which will determine when the power exercised by the act shall take effect and be enforced.
Delegation can be either explicit or implicit.
Raley v. State , Del. Super., Cr. In any event, the authority granted to an administrative agency should be construed so as to permit the fullest accomplishment of the legislative intent or policy. An expressed legislative grant of power or authority to an administrative agency includes the grant of power to do all that is reasonably necessary to execute that power or authority. Even without any clearly settled law upon which to rely, we believe that the courts would reach a similar conclusion if this question were presented as a case or controversy. The General Assembly was most insistent in requiring the credit plan to be immediately instituted.
