CONSTITUTION OF THE COMMONWEALTH OF MASSACHUSETTS.
A Declaration of the Rights of the Inhabitants of the Commonwealth of Massachusetts.
Article CVI. Article I of Part the First of the Constitution is hereby annulled and the following is adopted:-
All people are born free and equal and have certain natural, essential and unalienable rights; among which may be reckoned the right of enjoying and defending their lives and liberties; that of acquiring, possessing and protecting property; in fine, that of seeking and obtaining their safety and happiness. Equality under the law shall not be denied or abridged because of sex, race, color, creed or national origin.
The people have a right to keep and to bear arms for the common defence. And as, in time of peace, armies are dangerous to liberty, they ought not to be maintained without the consent of the legislature; and the military power shall always be held in an exact subordination to the civil authority, and be governed by it.
II. Initiative Petitions.
Section 2. Excluded Matters
...No proposition inconsistent with any one of the following rights of the individual, as at present declared in the declaration of rights, shall be the subject of an initiative or referendum petition: The right to receive compensation for private property appropriated to public use; the right of access to and protection in courts of justice; the right of trial by jury; protection from unreasonable search, unreasonable bail and the law martial; freedom of the press; freedom of speech; freedom of elections; and the right of peaceable assembly.
