Sources of ideas for legislation are unlimited and proposed drafts of bills originate in many diverse quarters. Primary among these is the idea and draft conceived by a Member. This may emanate from the election campaign during which the Member had promised, if elected, to introduce legislation on a particular subject. The Member may have also become aware after taking office of the need for amendment to or repeal of an existing law or the enactment of a statute in an entirely new field.
In addition, the Member's constituents, either as individuals or through citizen groups, may avail themselves of the right to petition and transmit their proposals to the Member. The right to petition, is guaranteed by the First Amendment to the Constitution. Many excellent laws have originated in this way, as some organizations, because of their vital concern with various areas of legislation, have considerable knowledge regarding the laws affecting their interests and have the services of legislative draftspersons for this purpose. Similarly, state legislatures may "memorialize" Congress to enact specified federal laws by passing resolutions to be transmitted to the House and Senate as memorials. If favorably impressed by the idea, a Member may introduce the proposal in the form in which it has been submitted or may redraft it. In any event, a Member may consult with the Legislative Counsel of the House or the Senate to frame the ideas in suitable legislative language and form.
In modern times, the "executive communication" has become a prolific source of legislative proposals. The communication is usually in the form of a message or letter from a member of the President's Cabinet, the head of an independent agency, or the President himself, transmitting a draft of a proposed bill to the Speaker of the House of Representatives and the President of the Senate. Despite the structure of separation of powers, Article II, Section 3, of the Constitution imposes an obligation on the President to report to Congress from time to time on the "State of the Union" and to recommend for consideration such measures as the President considers necessary and expedient. Many of these executive communications follow the President's message to Congress on the state of the Union. The communication is then referred to the standing committee or committees having jurisdiction of the subject matter of the proposal. The chairman or the ranking minority member of the relevant committee usually introduces the bill promptly either in the form in which it was received or with desired changes. This practice is usually followed even when the majority of the House and the President are not of the same political party, although there is no constitutional or statutory requirement that a bill be introduced to effectuate the recommendations. The committee or one of its subcommittees may also decide to examine the communication to determine whether a bill should be introduced. The most important of the regular executive communications is the annual message from the President transmitting the proposed budget to Congress. The President's budget proposal, together with testimony by officials of the various branches of the government before the Appropriations Committees of the House and Senate, is the basis of the several appropriation bills that are drafted by the Committee on Appropriations of the House.
Many of the executive departments and independent agencies employ legislative counsels who are charged with the drafting of bills. These legislative proposals are forwarded to Congress with a request for their enactment.
The drafting of statutes is an art that requires great skill, knowledge, and experience. In some instances, a draft is the result of a study covering a period of a year or more by a commission or committee designated by the President or a member of the Cabinet. The Administrative Procedure Act and the Uniform Code of Military Justice are two examples of enactments resulting from such studies. In addition, congressional committees sometimes draft bills after studies and hearings covering periods of a year or more.
