The Supreme Court said Monday it won't hear an appeal from three sex trafficking victims who accuse advertising website Backpage.com of helping to promote the exploitation of children.

The justices left in place a lower court ruling that said federal law shields Backpage from liability because the site is just hosting content created by people who use it.

The women say they were sold as prostitutes in Massachusetts and Rhode Island through advertisements for escort services on the site when they were as young as 15. They say Backpage is not protected by the Communications Decency Act because the company not only hosted the ads, but created a marketplace that makes child sex trafficking easier. Backpage has denied those allegations.

The U.S. Supreme Court has again refused to hear an appeal by former Waterbury Mayor Philip Giordano, who is fighting a 37-year prison sentence for sexually abusing two young girls while in office.

The court’s decision was released Monday. Justices previously refused to hear two earlier appeals by Giordano.

Giordano was challenging a federal appeals court decision in June to dismiss his request to set aside or correct his sentence. Giordano says the prison sentence is unconstitutional and his lawyer during his 2003 trial, Andrew Bowman, made several mistakes.

Bowman has denied that he provided ineffective counsel.

A federal jury convicted Giordano in 2003 of violating the civil rights of two girls, ages 8 and 10, by sexually abusing them in the mayor’s office and other locations.
