SAN ANTONIO, Jan 8 (Reuters) - A public school district in Texas can require students to wear locator chips when they are on school property, a federal judge ruled on Tuesday in a case raising technology-driven privacy concerns among liberal and conservative groups alike.

U.S. District Judge Orlando Garcia said the San Antonio Northside School District had the right to expel sophomore Andrea Hernandez, 15, from a magnet school at Jay High School, because she refused to wear the device, which is required of all students.

The judge refused the student's request to block the district from removing her from the school while the case works its way through the federal courts.
