Not unanticipated. The New York Times has a report:
With a definitive vote by the lower house of Parliament, France on Tuesday became the world’s 14th nation, and the third in just two weeks, to approve marriage rights for same-sex couples.
The legislation is expected to be approved by the Constitutional Council and signed into law by President François Hollande in time to allow the country’s first same-sex weddings this summer.
Some conservative lawmakers have suggested overturning the law should they find themselves with a parliamentary majority, but it remains unlikely they would try to do so, despite their recent vocal opposition; opinion polling has consistently shown that a strong majority of French support marriage rights for same-sex couples, though the country remains more evenly split on the matter of adoption.
