The New Jersey Supreme Court has given the state Legislature a historic opportunity, and I don’t mean the chance to allow same-sex couples to marry. The Legislature has the chance to enact civil unions for all couples – same-sex and different-sex. New Zealand does it. So does the Netherlands, under the name “registered partnership.” Maine and the District of Columbia recognize “domestic partnerships” for both straight and gay couples, although both give domestic partners fewer rights than those accorded married couples. Even New Jersey’s current domestic partnership law allows different-sex couples to register – but only if both partners are over 62, presumably a nod to the impact of remarriage on certain pension and retirement benefits.
