The house of representatives shall have the sole power of impeachment of the governor and lieutenant governor and the senate the sole power to try such impeachments, and no such officer shall be convicted without the concurrence of two-thirds of the members of the senate.  When sitting for that purpose, the members of the senate shall be on oath or affirmation and the chief justice shall preside.  Subject to the provisions of this paragraph, the legislature may provide for the manner and procedure of removal by impeachment of such officers.

The legislature shall by law provide for the manner and procedure of removal by impeachment of the appointive officers.

Judgments in cases of impeachment shall not extend beyond removal from office and disqualification to hold and enjoy any office of honor, trust or profit under the State;  but the person convicted may nevertheless be liable and subject to indictment, trial, judgment and punishment as provided by law.
