No one can tell the duration and time taken for any case. You are trying to count the chicken before they are hatched.
This was your advice to the complainant: her to focus on studies and get settled
The same advice was tendered to you to focus on getting qualified ignoring the case but you are continuing the posts and there are 7 posts. If there is such a way to nullify these cases in less time, there can never be such noise on "me too" issues. Maybe, in future some civil servants may get such ideas remembering their sour experience.
Let Court decide the issue and everyone is equal and gets the opportunity of such submissions. The ball is not in your court. You can only qualify for the examinations with hard work and distracting your attention in a matter, which at present you can not do anything is not proper if you really care for your career.
