1. under the Disability Discrimination Act 1995, the "reasonableness" test for deciding whether an employer must make reasonable adjustments is objective whereas the "justification" test for deciding whether an employer was justified in treating a disabled person less favourably is subjective.

2. in considering whether "any arrangements made" by an employer place a disabled person at a disadvantage giving rise to the duty on him to make "reasonable adjustments", the proper comparators are not non-disabled people in general but rather are other persons in respect of whom those arrangements apply.
