Gay couples in Taiwan will be able to marry under a law separate from the one authorizing marriage between a man and a woman.

After Taiwanese voters passed three conservative and anti-gay marriage referendums, the government decided to legaliz gay marriage under a separate law, according to Quartz. Now, pro-LGBT groups are arguing that gay couples will not have the same legal protections as straight couples.

“This result is a bitter blow and a step backwards for human rights in Taiwan. However, despite this setback, we remain confident that love and equality will ultimately prevail,” Amnesty International Director Annie Huang said in a statement. “The Taiwanese government needs to step up and take all necessary measures to deliver equality and dignity for all, regardless of who people love.”

The referendums that passed were a result of the May 2017 ruling that the current law covering marriage in Taiwan discriminated against same-sex couples. They gave a two-year deadline, which allowed time for conservatives to put anti-LGBT legislation into action.
