Tinker v. Des Moines protects student speech at school unless it would substantially disrupt school operations. For decades, it was unclear how much of that protection, if any, extended to something posted from home, on a personal account, outside school hours. In 2021, the Supreme Court finally addressed that question directly in Mahanoy Area School District v. B.L. — a case that started with a frustrated cheerleader's weekend Snapchat post.
The facts: a weekend post about not making varsity
A student who failed to make her school's varsity cheerleading squad posted a photo on Snapchat over the weekend, off school grounds, using vulgar language to express frustration about the school and the cheer program. The post reached roughly 250 people, many of them fellow students. The school suspended her from the junior varsity cheer squad for a year, and she sued, arguing the punishment violated her First Amendment rights.
The Court's answer: less power, not no power
The Supreme Court sided with the student, ruling that the school district's decision to punish her violated the First Amendment. But the Court deliberately declined to draw a bright line saying schools can never regulate off-campus speech. Instead, it said schools generally have a diminished, not eliminated, interest in policing off-campus expression, and pointed to features of this case that mattered: the post was made off-campus, on a personal account, on a weekend, and did not target any individual or identify the school by name in a way that caused a substantial disruption.
That means the outcome in a different case, with different facts, is not automatically the same. A post that includes a specific threat, targets an identifiable student or staff member, or genuinely disrupts school operations is treated differently than a general complaint made off-campus and after hours.
Bullying, harassment, and threats are treated differently
Mahanoy did not weaken a school's ability to respond to genuine harassment or bullying that happens off-campus but affects a student's safety or ability to attend school, including cyberbullying that targets a specific classmate. Our article on cyberbullying and off-campus discipline covers that side of the line in detail; this article is about speech that criticizes, complains, or expresses frustration, which is closer to the Mahanoy facts.
The distinction the Court drew is roughly this: general expression the school merely dislikes gets real protection, while conduct that targets and harms a specific person is evaluated more like harassment, under different rules entirely.
What this means in practice
A general complaint about a coach, a class, or a school policy, posted off-campus on your own time on a personal account, generally has stronger protection after Mahanoy than many students assume schools allow. That protection gets weaker the closer the post gets to targeting a specific person, threatening someone, or causing a genuine, documented disruption once it reaches campus.
If you are disciplined for something posted off-campus, asking the school to identify exactly what disruption occurred, and when, is a fair and specific question — Mahanoy makes that disruption something the school actually has to point to, not just assume.
Remember this
- Mahanoy v. B.L. (2021) held schools have diminished, not zero, power to regulate off-campus student speech.
- The Court declined a bright-line rule; where the speech happened, its audience, and whether it targeted someone all matter.
- General complaints off-campus get real protection; targeted harassment or genuine, documented disruption does not.
- If disciplined for an off-campus post, ask the school to specifically identify the disruption it caused.
