Machan v Olney, 958 F3d 1212 (6th Cir. 2020)

The plaintiff, father of a middle school student, sued a police officer alleging that she violated his and his daughter’s constitutional rights by, over his objection, taking her to the hospital for a mental health evaluation and authorizing a blood draw for harmful substances after the principal told the officer that the student advised she had been contemplating suicide. The federal district court denied summary judgment, but the United States Court of Appeals for the Sixth Circuit reversed finding that the officer had probable cause to believe that the student was dangerous to herself, for purposes of a Fourth Amendment seizure and detention for a mental health evaluation and blood draw, and that the officer had qualified immunity from father and student’s substantive due process claims.
