The following is the text of the proposed constitutional amendment, developed jointly by leaders of the Massachusetts Legislature, which won preliminary approval March 11, 2004. It must pass again in the next session and then a vote of the people before becoming law.

It being the public policy of this Commonwealth to protect the unique relationship of marriage, only the union of one man and one woman shall be valid or recognized as a marriage in Massachusetts. Two persons of the same sex shall have the right to form a civil union, if they meet the requirements set forth by law for marriage.

Civil unions for same sex couples are established hereunder and shall provide entirely the same benefits, protections, rights and responsibilities that are afforded to couples married under Massachusetts law. All laws applicable to marriage shall also apply to civil unions.

This article is self-executing, but the General Court may enact laws not inconsistent with anything herein contained to carry out the purpose of this article.
