It ruled that positive action should only be applied to distinguish between candidates who are equally qualified for a role.
This is the point I find most objectionable....
No two candidates are equally qualified (and suitable) for a job.
How this actually works are standards are lowered and if a "diversity" candidate meets the lowered standards they are deemed "equally qualified" as the competition and given the nod over better suited/qualified candidates.
As this article highlights the police were only found out because they screwed over an especially well qualified candidate on this occasion.
