A parent has asserted that there exists a law that prohibits school attorneys from attending mediation if a parent does not have an attorney.  I have never been aware of such a law/rule.  I think  the parent has mistaken resolution sessions for mediations but is anyone aware of a federal law/rule that prohibits school attorneys from attending mediation if a parent does not have an attorney.  Also, are there any states that have such prohibitions?
