Judgment :- K.S. Radhakrishnan, J. This appeal is preferred by the Manager of an aided aggrieved by the judgment of the learned single judge upholding rule 51 A claim of the writ petitioner for appointment to the post of High School assistant (Mathematics) in the vacancy which arose in this school on 6.6.2001. Appellant-Manager took up the stand that writ petitioner was appointed by an incompetent manager. Consequently the very appointment of the writ petitioner earlier was illegal and irregular. 2. Counsel for the writ petitioner - first respondent herein placed reliance on the decision of a Division Bench of this court in Padmanabhan Nambiar v. Government of Kerala (1997 (2) KLT 725). Writ petitioner was appointed by one N.K. Poulose, then approved Manager of the school in a leave vacancy which arose from 17.11.1997 to 17.1.1998 by appointment order dated 17.11.1997. That appointment was approved by the District Education Officer on 16.2.1998. Vacany of H.S.A. (Mathematics arose in the school with effect from 6.6.2001. Writ petitioner expected since he was a Rule 51-A claimant he would be appointed in the said vacancy by the present Manger. Instead, Manager invited applications from candidates by publication. The writ petitioner then sent a letter dated 25.5.2001 to the Manager claiming appointment to the post of H.S.A. (Mathematics). Disregarding his claim, Manager appointment to the post of H. S.A. (Mathematics). Disregarding his claim, Manager appointment third respondent in the vacancy which arose on 6.6.2001. Aggrieved by the same writ petition has been preferred. Learned single judge disposed of the writ petiton has been preferred. Learned single judge disposed for the writ petition on 14.6.2001 directing the District Educational officer to consider the claim raised by the writ petitioner with notice to him as well as the Mnager and the appointee. It was ordered that till orders are passed, appointment of third respondent would not be approved. 3. When the matter came up for hearing counsel on either side submitted that this court should decide the matter finally rather then driving the parties to the District Educational Officer. Certain facts are not disputed in this case. The fact that N.K. Poulose was approved Manger of this school is not denied. Case put up by the present Manager since he was not appointed by the Vicar of the Church. St. Certain facts are not disputed in this case. The fact that N.K. Poulose was approved Manger of this school is not denied. Case put up by the present Manager since he was not appointed by the Vicar of the Church. St. Mary's High School, Managership of which was indispute at the relevant time, was owned by St. Mary's Church, Kandanad. With regard to ownership of the church etc. there was litigation between the two factions of the church, namely Catholicos faction and Partiarch faction. Contention was raised by the present manager that N.K. Poulose was illegally elected manger in a meeting held on 8.9.1996 by the priest who was not the Vicar of the church. Based on the decision taken in the metting held on 8.9.1996.N.K.Paulose got his appointment as manager apponted District Education Officer on 11.9.1996, Present Manager of the school filed O.S. No. 30 of 1997 seeking declaration that he is lawfully elected Manager of St.Mary,s High School and that N.K. Poulose was not validly elected Manger. Injunction was alo sought for restraining him from functioning as Manager of the School. Injunction was granted by the District court in I. A. No 2217 of 1997 on 6.4.1998 restraining N.K. Poulose from acting as Manager of the School and also restraining one Father John Punnachalil from functioning as Vicar of St. Marthoma Orthodox Syrian Church , Kandanad till the disposal of the suit. Suit is still pending consideration. Pending suit Poulose died. 4. Counsel for the appellant-second respondent contended that since Poulose was not legally elected Manager of the school, appointments effected by him during his tenure are illegal and irregular. Counsel for the writ petitioner, as we have already indicated, placed reliance on the decision of this court in Padmanabhan Nambiar's Case, supra (1997 (2) KLT 725). Counsel also submitted that Poulose was the approved Manager of the school. Even though appeal was filed against the order of approval by the district Educational Officer to the Deputy Director of Education, the said order has not been reserved. 5. We find writ petitoner was appointed by the then Manager in a leave vacany which arose from 17.11.1997 to 17.1.1998. When write petioner was appointed, admittedly Poulose was the approved Manager even though the manner in which he was appointment of the writ petitioner was also subsequently approved by the District Educational officer on 16.2.1998. 6. 5. We find writ petitoner was appointed by the then Manager in a leave vacany which arose from 17.11.1997 to 17.1.1998. When write petioner was appointed, admittedly Poulose was the approved Manager even though the manner in which he was appointment of the writ petitioner was also subsequently approved by the District Educational officer on 16.2.1998. 6. Section 7 of the Kerala Education Act aurthorises the educational agency to appoint any person to be the manger of an aided school subject to approval of the educational authorities authorized by the Government. Manager shall be responsible for the conduct of the school in accordance with the provisions of the Act and Rules framed thereunder. Section 11 deals with appointment of teachers in aided schools, which says that subject to the rules and conditions laid down by the Government teachers of aided schools shall be appointed by the managers of such schools from among persons who possess the qualifications prescribed under Section 10 of the Act. Rule 3 of Chapter III of the Kerala Education Rules says that management of every aided school may be vested by the Educational Agency in a person who shall be referred to as the Manger and who shall be responsible to the department for the management of the institution. In the case of aided institutions under individual management the proprietary body may choose the Manager in accordance with the rules in that behalf referred to in Rule2. Sub-rule the rules in that behalf referred to in Rule 2. Sub-rule (4) says that the Educational Agency shall be bound by the acts of the Manager. Rule 4 deals with approval of appointment of Managers. Educational authorities shall be competent to approve the appointment of Managers by Educational Agencies and to approve changes in the personnel of the Managers. Rule 9 prescribes the duties and powers of the managers of aided schools. Manager shall also abide by the orders that may be issued from time to time by the Government and the Department. He shall also abide by the orders that may be issued from time to time by the Government and the Department. He shall also sign all the bills relating to the maintenace and other grants specifically granted to the Management. Managers shall appoint candidates who possess the requisite qualifications under the Rules as teachers. He shall also abide by the orders that may be issued from time to time by the Government and the Department. He shall also sign all the bills relating to the maintenace and other grants specifically granted to the Management. Managers shall appoint candidates who possess the requisite qualifications under the Rules as teachers. Rule 9 of Chapter XIV-A stipulates that appointment order shall not be affected any change in the Educational Agency or the manager. It is in compliance with the aforementioned statutory provisions Poulose who was the approved Manager appointed the writ petitioner in a leave vacany. Appointment of the writ petitoner was also approved by the district Educational Officer. Since he has got approved service and since he was relieved he has got a claim under Rule 51-A for future appointment. Therefore when vacancy arose on 6.6.2001 he was the legitimate person to be considered for appointment in that vacancy. 7.We are of the view mere fact that the appointment of the manger was subsequently found to be illegal or irregular could not take away the rights of the appointees. As far as appointees are concerned, they are appointed by approved Manger. They are not concerned with the dispute with regard to the managership of the school. There was no order either from the court or from the educational authorities restraining the then Manger from appointing the writ petitioner. Even if there is some illegality or irregularity in the appointment of the Manager, action taken by him during the tenure of his managership would not be illegal or irregular. All rights and liabilities flowed from those actions would be saved by the de factor doctrine,This principle has been upheld by this court in Padmanbhan Nambiar's case, supra. 8. Counsel for the appellant Sri B.G. Bhaskar contended that since Poulose happened to be an intruder to the office of the Manger, all actions taken by him during his tenure as manger will have to be declared as nuall and void. Counsel submitted that N.K. Poulose was elected to the post of manger by a person who has no legal right to conduct election. Counsel tries to distinguish the aforementioned decision of the Division Bench stating that de facto doctrine would not apply since that was a cae where there was a joint applicaton by both the Mangers to effect appointment.

He tried to distringuish the said decision on facts. 9. De factor doctrine saves the acts of the officers de fator performed within the scope of their assumed official authority. Whatever defects there may be in the nature of their appointment it is based upon the principle of public policy and necessity. Such a doctrine was introduced into the law as a matter of policy and necessity, to protect the interest of the public and the individual whose interests were involved in the official acts of persons exercising the duties of an office without being lawful officers. Aforementioned doctrine was applied by a Full Bench of this court in P.S. Menon v. Stateof Kerala (AIR 1970 Kerala 165) and held as follows: " The doctrine was engrafted as a matter of policy and necessity to protect the interest of the public and individuals involved in the offical acts of person exercising the duty of an officer without actually being one in strict point of law. But although these officers are not officers de jure they are by virtue of the particular circumstances, officers, in fact, whose acts, public policy requires should be considered valid." The judgment of the Full Bench was quoted with approval by the apex court in Gokaraju Rangarju v. State of A.P. (AIR 1981 S.C. 1473). That was a case where appointment of Sessions Judge was subsequently declared as invalid on the ground that the appointment was in violation of Article 233 of the Constitution of India. The apex court held that the judgments pronounced by him and acts done by him when he was clothed with the powers and functions of the office, albeit unlawfully, have the same efficacy as judgments pronounced and acts done by a Judge de jure. Above decision was subsequently followed by the apex court in C.Rangaswamiah and others v, Karnataka Lokayukta and others (1998 (6) SCC 66). Above decision was subsequently followed by the apex court in C.Rangaswamiah and others v, Karnataka Lokayukta and others (1998 (6) SCC 66). The apex court in a recent decision in Union of India v.Charanjit S.Gill and others (2000 (5) SCC 742) upheld the de facto doctrine and held that the doctrine in borne out of necessity. United states Supreme Court in New Zealand and Norton v. Shelby County (1886-118 US 425) while dealing with doctrine and held as follows: " Where an office exists under the law, it matters not how the appointment of the incumbent is made, so far as the validity of his acts are concerned. It is enough that he is clothed with the in signia of the office, and exercise its powers and functions. ……… The officials acts of such persons are recognized as valid on grounds of public policy, and for the protection of those having official business to transact." It is apposite to refer to the pronouncement of Lord Denning. The observations of Denning. The observations of Lord Dening are as follows: " He sits in the seat of a judge. He wears the robes of a judge. He Holds the office of a judge. May be he was not validly appointed. But still he hold the office.n nIt is the office that matters, not the incumbent….So long as the man matters, not the incumbent…. So long as the man holds the office and exercise it dutly and in accordance with law, his orders are not a nullity. If they are erroneous they may be upset on appeal. But if not erroneous they should be upheld." (Re James(An Insolvent) 1977 (1) All.E.R. 364 (CA). In the instant case we find Manager was elected and the same was approved by the educational authorities. Appointment effected by the Manger in a leave vacancy was also approved by the educational authorities. If appointment was not effected at that time in a leave vacany students would have been adversely affected. Manager and the educational authorities were legally obliged to protect the interest of the students. It will not be in the interest of the students to keep the leave vacancy open till the dispute with regard to the mangership is resoved. If appointment was not effected at that time in a leave vacany students would have been adversely affected. Manager and the educational authorities were legally obliged to protect the interest of the students. It will not be in the interest of the students to keep the leave vacancy open till the dispute with regard to the mangership is resoved. We have already pointed out public interest demands that the post of High School Assistant (Mathematics) be not kept unfilled till the dispute with regard to the mangership is resoved, instead that post has been filled up by the erstwhile manger even if his appointment was irregular. We are of the view whatever rights accrued to the appointee on the basis of that appointment would enure to his benefit and in our view would not be lost. We therefore hold that writ petitioner has got a claim and protection under Rule 51-A of Chapter XIV-A of the Kerala Education Rules. Rights are declared. Writ petitioner is the eligible person to be appointed in the vacancy which arose in the school on 6.6.2001. Writ appeal is accordingly dismissed.
