8. We understand that there are a considerable number of other pilots with defective colour vision who have requested the granting of licences which do not contain a condition prohibiting their piloting aircraft at night. For that reason the respondent indicated that it wished to conduct this case as a test case. Mr Rose, therefore, informed the Tribunal that the respondent intended to present its case in a manner which would encompass not only the applicant's situation but also broader issues relating generally to defective colour vision. At the request of the respondent the Attorney-General granted legal aid to the applicant to ensure that he was not disadvantaged by the respondent presenting his case in that manner. The matters which we have to consider in these proceedings have consequently been extended well beyond those which the applicant originally sought to raise, that is to say whether his defective colour vision made it unsafe for him personally to pilot an aircraft at night. The proceedings have taken 28 hearing days.
