ORDER

Delay condoned.

2. This petition for special leave arises from the order of the High Court of Gujarat in Special Civil Applications Nos. 12748 to 12757 of 1993.

3. The respondents-senior clerks who belonged to Scheduled Tribes represented to the Government to accord them the benefit of the proviso to Rule 11A of Gujarat Civil Services Classification and Recruitment (General) Rules, 1985 (for short, the Rules). On denial thereof, they approached the Gujarat Civil Services Tribunal which by its order dated 5-2-1993 directed the petitioner to consider their cases for promotion giving them the benefit of the proviso. The Tribunal followed its earlier Full Bench judgment and had given direction accordingly. On revision, the High Court has confirmed the same.

4. Shri Dave, the learned counsel appearing for the petitioner has contended that the interpretation given by the Tribunal and the High Court, if found acceptable, renders the main part of Rule 11-A redundant and the proviso would become operative in every case. Therefore, the matter requires consideration by this Court. We do not find force in the contention.

5. Sub-rule (1) of R. 11-A(2) speaks of minimum service of different classes of employees. It postulates that "where any rule or order relating to recruitment or promotion to any service or post including the State service or subordinate service, possession of experience in a lower services or post for a specified period is not prescribed as a condition precedent to promotion to a Higher service or post, the provisions of sub-rule (2) shall apply. Sub-rule (2) prescribed the procedure. In case of promotion from a lower post in Class III to a higher post in the same service a minimum of 5 years service has been prescribed in clause (a) to Rule 11-A(2). Similarly, from Class III to Class II service, experience of 7 years has been prescribed in clause (b). In clause (c) from a lower post in Class II service to a higher post in the same service a minimum experience of 5 years in the post from which a person is to be promoted has been prescribed. In Cl. (d) for promotion from Class II service to Class I service an experience of 8 years in Class II service has been prescribed unless he has experience of 8 years service in Class II service from which he is to be promoted. The proviso which is relevant for the purpose of this case, reads thus :

"Provided that where an appointing authority is satisfied that a person having an experience specified in clauses (a), (b), (c) or as the case may be, (d) is not available for promotion and that it is in public interest to fill up the post or service by promotion of a person having experience for a lesser period. It may for the reasons to be recorded in writing promote such person who has experience for a period not less than two-thirds of the period specified in clauses (a), (b), (c) or (d) which applies to him."

It would thus be clear that clauses (a) to (d) of sub-rule (2) of Rule 11-A prescribe a minimum experience in a lower post for promotion to a higher post, but the proviso enables the appointing authority on its satisfaction that the person required to have the previous experience prescribed under clauses (a) to (d) is not available for promotion and that in the public interest the post or service is required to be filled up by promotion, the provision postulates that such person has to put in, not less than two-thirds of the period specified in either clauses (a) to (d). Then it enables the appointing authority for reasons to be recorded in writing to promote such person. It is settled law that the proviso and the main part of the Act or Rule are to be harmoniously read together and interpreted to give effect to the object of the provision. Rule 11-A prescribes minimum period of previous experience in lower post for promotion to a higher post. It is normal rule. But, where the candidate is not available fulfilling the minimum experience but the exigencies of the administration re
