Petitioners in these Writ Petitions are claiming the benefit of R.5A of the Kerala State and Subordinate Services Rules (Hereinafter referred to as the "Rules" for short). In W.P.(C) No.11650/11, there is also an alternative prayer to declare the Rule unconstitutional.

2. Issues raised being common, these cases were heard together and are disposed of by this common judgment.

3. The background in which these litigations arise is that by G.O.(P) No.5/1993 dated 15.1.1993, R.5A was inserted in the Rules, which read as under:

"Where the method of recruitment to any service, class or category is by direct recruitment on district wise basis, such of the candidates belonging to that district who qualify for the interview/become qualified to be included in the ranked list for such of the district-wise posts mentioned in the Annexure to this rule shall be given a weight age of five marks for the selection:

Provided that the candidates who are eligible to get the above weight age marks shall produce along with the application a nativity certificate issued by a competent authority not below the rank of Tahsildar of the concerned Taluk".

(Annexure is omitted)

4. The Explanatory Note to this notification, being relevant, reads as follows:

"At present, the District Offices of the Kerala Public Service Commission are making district-wise selection to certain specified posts. The Kerala Public Service Commission has reported to Government that the candidates belonging to backward district such as erstwhile Malabar area do not get appointment against vacancies to be filled up by district wise selection in their native districts due to tough competition from candidates of other districts. To solve this problem to some extent, the Kerala Public Service Commission has been suggested that weight age of five marks may be given to candidates of native district for district-wise selection for Last Grade and Sub-Clerical posts. Government accept the suggestion of the Kerala Public Service Commission and propose to amend the Kerala State and Subordinate Services Rules, 1950 for this purpose. This notification is intended to achieve the above object."

5. Subsequently by G.O.(P) No.10/2011/P.&ARD dated 28.2.1 1, the Rule was substituted, which also being relevant, is extracted as follows:

"Where the method of recruitment to any post of any service class or category is by direct recruitment on district wise basis, such candidate belonging to that district shall be given a weight age of 5 marks for selection:

Provided that candidates who are eligible to get the above weight age marks shall produce a nativity certificate issued by a competent authority not below the rank of a Tahsildar of the concerned district as and when called for.

The entire annexure to R.5A in Part II Kerala State and Subordinate Service Rule, 1958 shall be deleted".

6. As is clear from the Rule itself, which is reiterated in the counter affidavits filed by the State and the P.S.C., both under the rule as it originally stood and as amended, the benefit of weight age is granted only to those candidates who produced Nativity Certificates. In so far as the issuance of the Nativity Certificates is concerned, in the Counter Affidavit filed by the State, it is stated that by G.O.(MS)No.205/83/RDdt26.2.1983 guidelines have been prescribed, which are the following:

"(1) Where father and mother are born natives of Kerala, Nativity Certificate will be issued to them as well as to their children.

(2) Where father or mother is a native of another State and on marriage they are permanently residing in Kerala, Nativity Certificate will be issued to their children.

(3) In other cases, only residential certificates will be issued".

7. Counter affidavits also reveal that there was no uniform format for the Nativity Certificates and that in order to remove the consequent difficulties, the Public Service Commission (hereinafter referred to as the "PSC" for short) wrote to the Government as pe
