The Constitution of Pennsylvania is the supreme law within the Commonwealth of Pennsylvania. All acts of the General Assembly, the governor, and each governmental agency are subordinate to it. Since 1776, Pennsylvania's Constitution has undergone five versions. The current Constitution entered into force in 1968, and has been amended numerous times.
The Constitution may only be amended if a proposed modification receives a majority vote of two consecutive sessions of the General Assembly and then is approved by the electorate. Emergency amendments are permitted by a vote of two-thirds of the General Assembly and an affirmative vote by the electorate within one month. In such emergency situations, commonwealth election officials are required to publish notice of the referendum on a proposed amendment in a minimum of two newspapers in every county. In an event that more than one emergency amendment is proposed, each additional amendment is to be voted on separately.[1]
The current Constitution of Pennsylvania comprises the following concise Preamble, and Articles and Schedules:
Pennsylvania has had five constitutions during its statehood:[2] 1776, 1790, 1838, 1874, and 1968. Prior to that, the colonial Province of Pennsylvania was governed for a century by a book titled Frame of Government, written by William Penn, of which there were four versions: 1682, 1683, 1696, and 1701.[3]
The unicameral legislature established in 1776 was abolished in 1790 in favor of a bicameral legislature.
