Here is a link to the Fifth Circuit’s order. The divided panel sent the Texas Heartbeat case to the Texas Supreme Court.
This order was issued after the case was remanded to the 5th Circuit by the US Supreme Court. The US Supreme Court, which refused a request to enjoin the law pending the challenges to the constitutionality of the statute, suggested that Texas licensing authorities might be proper defendants in the suits challenging the constitutionality of the Texas law. The US Supreme Court did not definitively settle that issue and the 5th Circuit has now certified the question to the Texas Supreme Court to decide this issue of state law.
