Moreover, the State Governor may not appoint a temporary replacement, but must instead arrange for a special election to fill the vacancy . The original qualifications and procedures for holding that election are still valid . </P> <P> The House of Representatives shall chuse (sic) their Speaker and other Officers; and shall have the sole Power of Impeachment . </P> <P> Section Two further provides that the House of Representatives may choose its Speaker and its other officers . Though the Constitution does not mandate it, every Speaker has been a member of the House of Representatives . The Speaker rarely presides over routine House sessions, choosing instead to deputize a junior member to accomplish the task . </P> <P> Finally, Section Two grants to the House of Representatives the sole power of impeachment . Although the Supreme Court has not had an occasion to interpret this specific provision, the Court has suggested that the grant to the House of the "sole" power of impeachment makes the House the exclusive interpreter of what constitutes an impeachable offense . </P>
