The Supreme Court heard arguments over the telephone Tuesday in a case to determine the constitutionality of a 2003 law that forces overseas affiliates of U.S.-based nonprofit groups to denounce prostitution in order to be eligible for federal funding to fight the AIDS epidemic. Aid groups have long said the law hampers the ability of their overseas affiliates from providing advice to sex workers about the risks of HIV infection.

In other Supreme Court news, 87-year-old Justice Ruth Bader Ginsburg was back in the hospital on Tuesday for nonsurgical treatment for a gallbladder condition. She is still planning to take part in today’s telephone oral arguments in a case about the Affordable Care Act and birth control.
