Maine Constitution Art. I, § 7. No person to answer to certain crimes but on indictment; exceptions; juries

Section 7. No person shall be held to answer for a capital or infamous crime, unless on a presentment or indictment of a grand jury, except in cases of impeachment, or in such cases of offenses, as are usually cognizable by a justice of the peace, or in cases arising in the army or navy, or in the militia when in actual service in time of war or public danger. The Legislature shall provide by law a suitable and impartial mode of selecting juries, and their usual number and unanimity, in indictments and convictions, shall be held indispensable.
