"17. In those circumstances, in summary, the tribunal finds that the effects of the recurrence of the applicant's depressive illness which recurred from some time in late 2001, whilst being long term did not have a substantial adverse effect on the applicant's ability to carry out normal day-to-day activities up to the period10 January 2003 . The tribunal finds that the deduced effects, i.e. the effects without the prescribed Fluoxetine would not be such that they would have a substantial adverse effect on the applicant's day-to-day activities during the same period and the tribunal finds that on the balance of probabilities the substantial adverse effect was not likely to recur, and therefore the substantial adverse effect is not treated as continuing. In those circumstances, and for all the reasons given, we find that whilst the applicant was a person with a disability during the period23 November 1998 to15 September 2000 , but he was not a person with a disability during the period thereafter. In coming to our conclusions we bear in mind that the material time at which to assess the disability generally, i.e. whether there is an impairment which had a substantial and long-term adverse effect on the ability to carry out normal day-to-day activities is the date of the alleged discriminatory act which in this case relates to the period in dispute, namely16 September 2000 to 10 anuary 2003."
