The Confederate flag is under continued scrutiny, and one Virginia high school ended up suspending students at the beginning of the new school year for wearing clothes depicting the controversial flag and then refusing to comply when given the opportunity, USA Today reports.

Montgomery County Public Schools spokeswoman Brenda Drake said that some 22 or 23 students at Christiansburg High were punished Thursday for violating the dress code and refusing to back down when given a chance. All were given a one-day, in-school suspension. However, many of the students became unruly, turning most of the suspensions into out-of-school suspensions, the newspaper reported.

According to the report, on the first day of school, three students were asked by school Principal David Siers to remove Confederate-flag decals from their cars. The students did so.

Confederate-flag symbols were banned from cars starting this school year, and students were required to sign an agreement to follow the rules in order to get  a parking pass, the site notes.
