After 15 hours of debate, the Senate voted 33 to 27 in favor of the measure, which was sponsored by the government of President Cristina Fernández de Kirchner. For weeks, she waged a bitter war of words with the Roman Catholic Church over the measure. The church organized large protests throughout the country on Tuesday night involving tens of thousands of opponents of the law. Some senators criticized the Senate leadership on Wednesday for not allowing a vote on an alternative bill to authorize civil unions for gay couples. The same-sex marriage measure will give gay people the same marital rights as heterosexuals, including adoption and inheritance rights. Mexico City became the first jurisdiction in Latin America to legalize same-sex marriages last year. Two other countries in the region, Uruguay and Colombia, allow civil unions for same-sex couples.
