Iowa Constitution Art. III, § 20. Officers subject to impeachment--judgment

The governor, judges of the supreme and district courts, and other state officers, shall be liable to impeachment for any misdemeanor or malfeasance in office; but judgment in such cases shall extend only to removal from office, and disqualification to hold any office of honor, trust, or profit, under this state; but the party convicted or acquitted shall nevertheless be liable to indictment, trial, and punishment, according to law. All other civil officers shall be tried for misdemeanors and malfeasance in office, in such manner as the general assembly may provide.
