First you apply if they reject then legal consequence arises.

The provision is just and fair. As such, there is no relevance in searching for Court Judgments.

YOu cannot challenge after appearing in the selection process. You need to challenge before appearing.

If policy is defined and appear it proves you have accepted the policy and later you cannot challenge normally and lot of judgements are there.

But defining guidelines is the matter of recruiter for fair selection and if you feel it is not fairly designed you should challenge it before appearing in the process.
