The proposed amendment cleared a first reading last year but had been shelved before a committe could discuss it largely due to opposition from religious groups. Bills must pass three readings in order to be sent to the president to be promulgated.

Last year, tens of thousands of people took to the streets of Taipei to protest against gay marriage while earlier this month, thousands took part in a rainbow run in Taipei in support of gay marriage.
