Can a school deny academic credit as part of school discipline for work that has already been completed? How far does a school’s authority go? At what point during the semester should you play it safe and leave your marijuana at home? In this episode, we go back to South Gibson High School in Indiana in 1998, where a zero-tolerance drug policy set off a chain of events that sparked a pretty interesting legal battle with some fascinating implications. We have a student who got caught with marijuana crumbs in his truck and was expelled in the last few days of the fall semester of his junior year. As part of the expulsion, the school denied the student academic credit for the entire fall semester, even though he only had 3 days left when he was expelled and otherwise would have passed some of his courses. This is the case of South Gibson School Board v. Sollman. We also discuss a recent report about potential racial bias in AI detectors.
