NEW ORLEANS (AP) — A federal judge is weighing a bid to dismiss a lawsuit challenging a Louisiana law that has required people convicted of soliciting oral or anal sex to register as sex offenders.

U.S. District Judge Martin Feldman didn’t immediately rule Wednesday after hearing the state’s request to throw out the lawsuit over its 200-year-old “crimes against nature” law.

Civil rights attorneys who filed the suit claim the law is unconstitutional and discriminatory and unfairly condemns sex acts traditionally associated with homosexuality.

The state says the plaintiffs — an anonymous group of registered sex offenders — don’t have a constitutionally protected right to privacy after being convicted of engaging in sex acts for money.
