A dispute has taken place among contributors as to what the Pennsylvania Constitution has to say about who is subject to impeachment. Below is the relevant excerpts from Pennsylvania Constitution:
Power of Impeachment
Section 4.
The House of Representatives shall have the sole power of impeachment.
Trial of Impeachments
Section 5.
All impeachments shall be tried by the Senate. When sitting for that purpose the Senators shall be upon oath or affirmation. No person shall be convicted without the concurrence of two-thirds of the members present.
Officers Liable to Impeachment
Section 6.
The Governor and all other civil officers shall be liable to impeachment for any misbehavior in office, but judgment in such cases shall not extend further than to removal from office and disqualification to hold any office of trust or profit under this Commonwealth. The person accused, whether convicted or acquitted, shall nevertheless be liable to indictment, trial, judgment and punishment according to law.
Removal of Civil Officers
Section 7.
All civil officers shall hold their offices on the condition that they behave themselves well while in office, and shall be removed on conviction of misbehavior in office or of any infamous crime. Appointed civil officers, other than judges of the courts of record, may be removed at the pleasure of the power by which they shall have been appointed. All civil officers elected by the people, except the Governor, the Lieutenant Governor, members of the General Assembly and judges of the courts of record, shall be removed by the Governor for reasonable cause, after due notice and full hearing, on the address of two-thirds of the Senate.
