"The Applicant has claimed that he was victimised in that the dismissal resulted from the fact that the councillors took into account that he had raised a grievance against Wendy Collins alleging race discrimination and also had put in an application to this Tribunal.
"In our judgment, where an industrial tribunal finds that there are mixed motives for the doing of an act, one or some but not all of which constitute unlawful discrimination, it is highly desirable for there to be an assessment of the importance from the causative point of view of the unlawful motive or motives. If the industrial tribunal finds that the unlawful motive or motives were of sufficient weight in the decision-making process to be treated as a cause, not the sole cause but as a cause of the act thus motivated, there will be unlawful discrimination. An important factor in this decision is clearly well within that principle."
"(6) Where the tribunal finds that the dismissal was to any extent caused or contributed to by any action of the complainant it shall reduce the amount of the compensatory award by such proportion as it considers just and equitable having regard to that finding."
