Chile’s Congress passed a law to legalize same-sex marriage on Tuesday, in a milestone for the conservative South American nation after a decade-long legal battle and with the country delicately poised ahead of a crossroads election this month. “Today is a historic day, our country has approved same-sex marriage, one more step forward in terms of justice, in terms of equality, recognizing that love is love,” Minister of Social Development Karla Rubilar said after the vote. Chile’s Senate and lower house of parliament both voted heavily in favor of the bill on Tuesday, which had previously been partially approved in November before the Senate sent it back to a committee to clarify ambiguities. Current President Sebastian Pinera, who will leave office in March, has backed the bill and is expected to sign it into law.
