SAN ANTONIO — A federal judge ruled in favor of student locator chips for a public school district in Texas Wednesday, according to NBC News. 

The chips are only intended to be worn while students are on school property, but the case has spurred privacy concerns among various groups. 

NBC News said the ruling came after a high school sophomore refused to wear the locator device, a requirement of all students. The judge said the school had every right to expel the student for refusing to follow the rules. 

The defendant's representation claimed the ruling violated the student's constitutional right to privacy and had plans to appeal.
