Can I sue the school for a false report
1 attorney answer
No, you cannot sue the school unless you have pretty solid evidence that the school "made up a false allegation against her 10yr old brother." Kids often don't understand the full implications of what they say, and the school may have simply misunderstood what your daughter was trying to say.
In any event, the school is required by law to report if the school "has a reasonable suspicion" that abuse may have occurred.
I'm licensed to practice law only in Indiana, and we've never met, so I can't give you "legal" advice. My answer is simply "friendly" advice based on my experience as an attorney in Indiana, my knowledge of federal and common law, and common sense. Even if you are in Indiana, employment law questions are very fact specific, and based on the limited information you provided in your post, I can't give you legal advice, and my answer is intended as general information only. It doesn't create an attorney-client relationship.
