Impeachment in the Northern Mariana Islands
In the Commonwealth of the Northern Mariana Islands (a United States territory), the process of impeachment allows its Commonwealth Legislature to remove certain officeholders. The territory's House of Representatives can initiate an impeachment, bringing about an impeachment trial in the territory's Senate through which an officeholder can be removed from their office.
