"The issue of justifiability is a question of fact. There is some guidance in the cases as to the test to be applied. In Ojituku the EAT spoke of "reasonably necessary" and "right and proper in the circumstances" and in the same case the Court of Appeal referred to reasons which are "sound and tolerable to right thinking people" and "good and adequate reasons"
"11. The Tribunal believes that the crucial factors for consideration in this case are as follows: (a) The applicant is a Muslim with deep religious beliefs. He has habitually attended the Mosque for Juma prayers on Friday afternoons since the age of 16. (b) Although attendance at the Mosque is the applicant's preference, he religious obligations could be performed elsewhere so long as the prayers were said between 1.30 pm and 4 pm on a Friday afternoon and provided there was a congregation of at least four people. (c) Notwithstanding that the applicant had been interviewed in March 2003 and had been in the School on 2, 4 and 5 June, the first the respondent knew of the applicant's requirements was less than 2 hours before he intended to go to the Mosque for prayers on 6 June. (d) The respondent runs a School catering for children with severe learning difficulties. (e) The applicant knew when he accepted the job that it was on a one-to-one basis and he knew what that entailed. (f) The pupil to be assigned to the applicant suffers from severe autism, had a history of behavioural problems which involved assaults on staff and pupils and had been expelled from his previous school. (g) The applicant was meeting the pupil for the first time on 6 June and the main object of the exercise was for the applicant to get to know the pupil out of the home environment. (h) The welfare of its pupils is a matter of paramount importance to the respondent. (i) In order to achieve its objectives the respondent operates an inflexible system in respect of timetabling and also one-to-one arrangements. (j) Had the applicant remained at the school the respondent would have assisting the applicant in finding a congregation from amongst its Muslim employees in order for Juma prayers to be said on Friday afternoons between close of school at 3.20 pm and 4 pm. (k) At the meeting on 9 June, whilst the respondent made it plain that it could not continue to employ the applicant on a one-to-one basis if he left school on Friday afternoon, it nonetheless made clear that the respondent was prepared to employ the applicant in alternative roles as and when available."
"The tribunal has considered all of the points referred to above individually, collectively and "in the round""
