As for the case in this posting, it has no legal base as well.
S/he cannot claim "DISCRIMINATION" when s/he is treated as same as his/her classmates.
S/he cannot ask for compensation when she never feels ill except uncomfortable as s/he stated in his/her complaining letter.
This case is a mistake at most. But School already corrected its mistake by increasing scores on each of the classmembers. What else does s/he want?
School committee gave her/him the final notice that this case was over and the decision was final.
I do not understand why s/he wants to go out of school to seek legal help. What is illegal here?
