The House of Lords' Decision
The House of Lords allowed Mrs Archibald's appeal and remitted the case to the employment tribunal.
They held:
The requirement that Mrs Archibald had to be physically fit to work amounted to an "arrangement" under section 6 (2)(b) of the Act which she was no longer able to meet and that exposed her to another "arrangement" or condition which was that if she was physically unable to do the job she was employed to do then she was liable to be dismissed. These arrangements placed Mrs Archibald at a substantial disadvantage in comparison to those non-disabled persons.
The positive duty to make reasonable adjustments may extend to positively discriminating in favour of disabled people.
The positive obligation to make reasonable adjustments potentially includes the right for disabled persons to "trump" other job applicants where the disabled person is suitable to do that work but may not be the best candidate for the job.
