I'm not saying I agree with this particular JP at all and I think it's unfortunate, but a JP, Pastor, or a Priest can and do decline based on age differences of the petitioners, backgrounds of the petitioners, his/her personal beliefs, and even impressions of the parties requesting. None are required to grant anyone a wedding.
as I understand it the JP is an elected official. as such I believe it is illegal for him to refuse service based on race. period.
please note that Louisiana's Judicial Code of Ethics requires officials like Bardwell to "perform judicial duties without bias or prejudice."
thats REQUIRES. no maybe about it.
