Same-sex marriage bill signed into law in Ireland

The traditionally Catholic nation has become the world's first country to vote for gay unions

Same-sex marriage has been signed into law in Ireland, five months after a historic referendum saw the traditionally Catholic nation become the world's first country to vote for gay unions.

"The Presidential Commission today signed the 'Marriage Bill 2015' into law," the president's office said in a statement yesterday, paving the way for the first weddings within a month.

Ireland voted 62.1% in favour of allowing marriage between two people "without distinction as to their sex" in May, the first time anywhere that gay marriage has been legalised in a referendum.

The president's endorsement was the final hurdle for the bill after legal challenges briefly delayed the legislation from coming into effect.

The first ceremonies should be possible by mid-November, according to Justice Minister Frances Fitzgerald.

Senator Katherine Zappone, who had long campaigned for her Canadian marriage to her wife to be recognised in Ireland, called it "a defining moment".

"It is a deeply emotional moment for those of us who have campaigned for so long," Zappone said in a statement.

"This victory truly belongs to the nation, it is a moment for us all."

In a memorable moment that unfolded live on national television after the referendum result was announced, Zappone proposed to her wife Ann Louise Gilligan to re-marry her under Irish law.

International gay rights campaigners congratulated efforts by Irish activists to win public support for a "Yes" vote in the referendum.

"Tribute must also be paid to national politicians in Ireland, as all the main political parties put aside their partisan differences to campaign for the greater goal of equality," Evelyne Paradis of the International Lesbian, Gay, Bisexual, Trans and Intersex Association said in a statement.

President Michael D Higgins is on a visit to the United States, so in his place the bill was signed by senior delegates of the Presidential Commission.
