France's Constitutional Council on Friday approved a gay marriage bill passed by parliament on April 23.

“#BREAKING: France's constitutional court clears gay marriage bill,” the AFP tweeted.

President Francois Hollande is expected to sign the bill into law next week.

After lawmakers gave final approval to the measure, conservative UMP deputies referred it to the Council, which has the authority to strike it down.

Approval is a victory for Hollande, who campaigned on the issue of marriage equality.

However, opponents are expected to continue their loud protests. A demonstration in Paris is planned for Sunday, May 26. A protest last month ahead of a final vote on the bill turned violent, resulting in more than 100 arrests as activists damaged cars and public property and attacked police officers and two journalists. Police detained three protesters carrying canisters of teargas.

The law, which also legalizes adoption for gay couples, is expected to take effect sometime in June.

France becomes the 14th nation to allow gay and lesbian couples to marry, following the recent additions of Uruguay and New Zealand, and the 9th in Europe. A recent court ruling has effectively legalized such unions in Brazil.
