The Religious Accommodations Act, or HB 1523, allows public officials and businesses to refuse service to anyone based on a religious opposition to same-sex marriage, transgender people or premarital sex.
"HB 1523 has no rightful place in Mississippi or in our history books, and we’re hopeful this lawsuit can stop as much of it as possible before it goes into effect," ACLU staff attorney Josh Block stated.
On Monday, the ACLU said the Mississippi law "directly contradicts the Supreme Court’s ruling by… singl[ing] out the marriages of same-sex couples and provides a special right for government officials and for-profit businesses to discriminate against them."
Mississippi Governor Phil Bryant signed the bill into law in April, and the legislation is scheduled to be implemented in July.
