A federal lawsuit has been filed against the state of Michigan for allowing faith-based adoption agencies to discriminate against gay couples seeking to adopt.

The ACLU filed the lawsuit Wednesday (9/20) on behalf of two Michigan couples and a foster parent and former foster child, challenging the religious exemptions used by the Michigan Catholic Conference and agencies charged with finding permanent homes for Michigan's 13,000 foster children.

According to The Detroit News, Governor Rick Snyder signed legislation in 2015 that afforded faith-based organizations the loophole needed to discriminate against same-sex couples.
