I guess technically you are correct in that anything could be grounds for a lawsuit, but I’m sure there is broad language in codes of conduct that give teachers/coaches/administrators wide leeway to determine what students can and cannot do.Yes as long as there is legal precedent allowing such behaviors in the same settings. If the school violates that without those rules in place, there is grounds for lawsuit and damages. That is what makes legal precedent and the courts so important. Also, this is why codes of conduct, school board policies, etc. are all constantly updated.
