Under House Rules, "charges transmitted by a State legislature" is one way to
set impeachment in motion, and further, that "a proposition to impeach. . . at once supersedes business otherwise in order."
House Rules For Impeachment
JEFFERSON’S MANUAL
§ 602. Parliamentary law as to accusation in impeachment.
Accusation. The Commons, as the grand inquest of the nation, becomes suitors for penal justice. 2 Wood., 597; 6 Grey, 356. The general course is to pass a resolution containing a criminal charge against the supposed delinquent, and then to direct some member to impeach him by oral accusation, at the bar of the House of Lords, in the name of the Commons. The person signifies that the articles will be exhibited, and desires that the delinquent may be sequestered from his seat, or be committed, or that the peers will take order for his appearance. Sachev. Trial, 325; 2Wood., 602, 605; Lords’ Journ., 3 June, 1701; 1Wms., 616; 6 Grey, 324
§ 603. Inception of impeachment proceedings in the House.
In the House there are various methods of setting an impeachment in motion:
by charges made on the floor on the responsibility of a Member or Delegate (II, 1303; III, 2342, 2400, 2469; VI, 525, 526, 528, 535, 536);
by charges preferred by a memorial, which is usually referred to a committee for examination (III, 2364, 2491, 2494, 2496, 2499, 2515; VI, 543);
by a resolution dropped in the hopper by a Member and referred to a committee (Apr. 15, 1970, p. 11941; Oct. 23, 1973, p. 34873);
by a message from the President (III, 2294, 2319; VI, 498);
by charges transmitted from: the legislature of a State (III, 2469) or territory (III, 2487) or from a grand jury (III, 488); or from facts developed and reported by an investigating committee of the House (III, 2399, 2444).
604. A proposition to impeach a question of privilege
A direct proposition to impeach is a question of high privilege in the House and at once supersedes business otherwise in order under the rules governing the order of business (III, 2045–2048, 2051, 2398; VI, 468, 469; July 22, 1986, p. 17294; Aug. 3, 1988, p. 20206; May 10, 1989, p. 8814; Sept. 23, 1998, pp. 21560–62; see Deschler, ch. 14, § 8). It may not even be superseded by an election case, which is also a matter of high privilege (III, 2581). It does not lose its privilege from the fact that a similar proposition has been made at a previous time during the same session of Congress (III, 2408), previous action of the House not affecting it (III, 2053). As such, a report of the Committee on the Judiciary accompanying an impeachment resolution is filed from the floor as privileged (Dec. 17, 1998, p. 27819), and is called up as privileged (Dec. 18, 1998, p. 27828). The addition of new articles of impeachment offered by the managers but not reported by committee are also privileged (III, 2401), as is a proposition to refer to committee the papers and testimony in an impeachment of the preceding Congress (V, 7261). To a privileged resolution of impeachment, an amendment proposing instead censure, which is not privileged, was held not germane (Dec. 19, 1998, p. 28107).
