PHILADELPHIA -

The Easton Area School District was back in court Tuesday to continue an ongoing battle over breast cancer bracelets.

The legal battle started in 2010 when the ACLU sued the school district on behalf of two students who were suspended for wearing the bracelets that say, "I heart boobies."

A judge ruled the ban unconstitutional, but now the district is appealing.

Opening arguments were scheduled Tuesday. A U.S. Appeals court in Philadelphia is hearing the case.
