Michigan Compiled Laws, Chapter 6. Impeachments § 6.2

Sec. 2. Every impeachment shall be tried by the senate. When the governor or lieutenant governor is tried the chief justice of the supreme court shall preside. When an impeachment is directed the senate shall take an oath or affirmation truly and impartially to try and determine the same according to the evidence. No person shall be convicted without the concurrence of 2/3 of the members elected. Judgment, in case of impeachment, shall not extend further than removal from office, but the party convicted shall be liable to punishment according to law.
