This measure amends the State Constitution to recognize marriage only between a man and a woman. In addition it defines a man as possessing a Y chromosome and a woman as not possessing such a chromosome. In addition, the measure prohibits the Legislature, courts, and state and local government agencies from granting the “rights, incidents, or employee benefits of marriage” to any unmarried persons or decreasing the existing marriage rights or benefits. The measure also prohibits government agencies from requiring private entities to extend the rights of marriage to unmarried persons.
