"In January the Applicant claimed that a technician referred him as Saddam Hussain. This is of course a deeply insulting and wounding remark to have made but unfortunately we have no evidence before us other than the Applicant's word and of course that stands as to who said it or in what circumstances. Certainly there is nothing in that that can be attributable to the first Respondent so as to make it vicariously liable. He also alleged that certain other individuals with whom he had had dealings had discriminated against him on grounds of race."
