The teacher who threw a paint bomb at Conservative chairman Brian Mawhinney has failed in his bid to extend the scope of the Race Relations Act to cover political activism.
Anthony Gard, 54, had told the East London industrial tribunal that he had been given a written warning by the governors of Langdon Park comprehensive, in Tower Hamlets, because he had campaigned on behalf of Bengali pupils.
The tribunal refused to accept that Mr Gard had been punished for his activism. It ruled that the school had acted because it thought it had broken Tower Hamlets council's code of conduct and that he had "brought the school into disrepute."
Mr Gard had been found guilty of assault, following his much-publicised paint attack on Mr Mawhinney outside Parliament in 1995.
