As a general rule, do not use the serial/Oxford comma: so write ‘a, b and c’ not ‘a, b, and c’. But when a comma would assist in the meaning of the sentence or helps to resolve ambiguity, it can be used — especially where one of the items in the list is already joined by ‘and’.
Section 1. Legislative intent. Marriage is a fundamental human right. Same-sex couples and their children should have the same access as others to the protections, responsibilities, rights, obligations, and benefits of civil marriage. Stable family relationships help build a stronger society. For the welfare of the community and in fairness to all New Yorkers, this act formally recognizes otherwise-valid marriages without regard to whether the parties are of the same or different sex. It is the intent of the legislature that the marriages of same-sex and different-sex couples be treated equally in all respects under the law. The omission from this act of changes to other provisions of law shall not be construed as a legislative intent to preserve any legal distinction between same-sex couples and different-sex couples with respect to marriage. The legislature intends that all provisions of law which utilize gender-specific terms in reference to the parties to a marriage, or which in any other way may be inconsistent with this act, be construed in a gender-neutral manner or in any way necessary to effectuate the intent of this act.
