JUDGMENT:- (1.) Vakalatnama filed on behalf of respondents be kept with the record. (2.) Mr. Banerjee has taken a preliminary objection in this matter drawing our attention to Paragraph-15 of the petition. Since it is a point of law there is no need for any affidavit-in-opposition. We have gone through the statement and averments made in the petition. Accordingly, we quote the exact language used in Paragraph-15 of the petition:- "15. That your petitioners state that thereafter the case filed and the decision for filing of an appeal/writ petition before the Honble Court were examined and vetted at various official levels of the Railway authority and finally, a writ petition was filed before this Honble Court on 20.07.2007 being W.P.C.T. No. 646 of 2007 (Union of India and Ors. v. Sri Pravash Dutta) by enclosing the original certified copy of the order dated 15.03.2007. Your petitioners further state that subsequently it has been decided that the W.P.C.T. should be withdrawn and the Honble Tribunals order implemented and accordingly a miscellaneous application should be filed before the Honble Tribunal for extension of time for compliance with the order dated 15.03.2007. Accordingly, the aforesaid writ petition was dismissed as withdrawn without merit on 15.10.2007." (3.) It is thus clear that earlier writ petition was withdrawn may be on some valid or invalid ground but without leave of the Court. Rule 53 of the Writ Rules framed by this Court has adopted the provisions of Civil Procedure Code to the extent it is applicable. Order 23 sub-rule 3 (b) and (4) sub-rule (b) provides as follows: -"(3) Where the Court is satisfied - (a)............................................................................... (b) That there are sufficient grounds for allowing the plaintiff to institute a fresh suit for the subject-matter of a suit, or part of a claim, it may, on such terms as it thinks fit, grant the plaintiff permission to withdraw from such suit or such part of the claim with liberty to institute a fresh suit in respect of the subject-matter of such suit or such part of the claim. (4) Where the plaintiff - (a)............................................................................... (b) Withdraws from a suit or part of a claim without the permission referred to in sub-rule (3). (4.) It is thus evident without permission, referred to in sub-rule 3; the litigant was precluded from instituting any fresh suit in respect of same subject-matter or same claim or part of the claim. (4) Where the plaintiff - (a)............................................................................... (b) Withdraws from a suit or part of a claim without the permission referred to in sub-rule (3). (4.) It is thus evident without permission, referred to in sub-rule 3; the litigant was precluded from instituting any fresh suit in respect of same subject-matter or same claim or part of the claim. (5.) Admittedly, the petitioner in this case has not obtained leave to file fresh application, as provided in the said rule. According to us the aforesaid provision has been adopted and substantiated in the body of the Code in Section 12 of the Code of Civil Procedure which specifically creates a bar which we set out hereunder: - "12. Bar to further suit Where a plaintiff is precluded by rules from instituting a further suit in respect of any particular cause of action, he shall not be entitled to institute a suit in respect of such cause of action in any Court to which this Code applies." (6.) "Rules", as provided in Section 2(18), means rules and forms contained in the First Schedule or made under Section 122 or Section 125. (7.) It is thus clear that the bar created in Order 23 sub-rule (4) has to be treated as substantive bar as mentioned in Section 12 in the Code of Civil Procedure. The said bar, in our view, is not a procedural bar and it creates substantive right in favour of the adversary with an object that a litigant ought not to be vexed twice over again like principle of resjudicata of course in different way. Under such circumstances, the preliminary objection succeeds and on that ground this application is dismissed. There will be no order as to costs.
