To address this, Proposition 22 did not reword the existing provisions of the Family Code, but added to them the declaration that "only marriage between a man and a woman is valid or recognized in California". The official citation of Proposition 22, the "California Defense of Marriage Act", is almost the same as that of a federal law, the Defense of Marriage Act, which was enacted by Congress in 1996. This federal law had a similar purpose, and was intended to prevent any state from being obligated to recognize a same-sex marriage contracted in another state.
