“32. There is an obvious distinction between qualifying through an entrance test for securing admission in a medical college and qualifying in the UPSC examinations since the latter examination is conducted for filling up vacancies in the various civil services. In the former case, all the successful candidates receive the same benefit of securing admission in an educational institution. However, in the latter case there are variations in the benefits that accrue to successful candidates because they are also competing amongst themselves to secure the service of their choice. For example, most candidates opt for at least one of the first three services [i.e. Indian Administrative Service (IAS), Indian Foreign Service (IFS) and Indian Police Service (IPS)] when they are asked for preferences. A majority of the candidates prefer IAS as the first option. In this respect, a Re- served Category candidate who has qualified as part of the general list should not be disadvantaged by being assigned to a lower service against the vacancies in the General Category especially because if he had availed the benefit of his Reserved Category status, he would have got a service of a higher preference. With the obvious intention of preventing such an anomaly, Rule 16 (2) provides that an MRC candidate is at liberty to choose between the general quota or the respective Reserved Category quota.
