I owuldn't have thought so, dev.
surely (in theory) every child is entitled to an education, and steps must be taken to ensure that this takes place. it might not mean school, though, but instead more home tuition.
parents do have a right to ask for school, but I assume the 'not detrimental to others in he class/school' also applies to SN school, so that could be the get-out.
HOWEVER, tht is not to say that the child should be denied a suitable education.
