Venkatarama Aiyar, J.
1. These are appeals against the judgment of the High Court of Patna in Second Appeals Nos. 2155 and 2156 of 1948 on certificates granted by the High Court under Art. 133(1)(c) of the Constitution. The facts leading to this litigation lie in a narrow compass. One Prithi Dubey died on July 14, 1932, leaving him surviving, his widow Laung Kuer, who succeeded as heir to his estate. For the purpose of discharging debts due by the deceased Laung Kuer executed on June 21, 1935, a Zerpeshgi deed in favour of two persons, Rajdewan Dubey and Kailash Dubey, who were also the next reversioners, for a sum of Rs. 1,100. It is not in dispute that this deed is binding on the reversioners. On June 17, 1943, Laung Kuer sold to the appellant a portion of the properties which were the subject-matter of the Zerpeshgi deed dated June 21, 1935, for a consideration of Rs. 1,600. Out of this amount, a sum of Rs. 1,100 was reserved with the purchaser for redemption of the Zerpeshgi, and the balance of Rs. 500 was paid in cash. It is recited in the deed of sale that a sum of Rs. 100 was required to effect repairs to the family dwelling house, a sum of Rs. 200 for purchasing two bulls for agricultural purposes, and a sum of Rs. 200 for repairing a well, which had been constructed by the deceased for user by the public and which was then in a ruined condition. It is to meet these expenses that Laung Kuer raised Rs. 500.
2. After obtaining the sale deed, the appellant sought to redeem the Zerpeshgi, but the Zerpeshgidars refused to receive the amount and surrender possession of the properties. The appellant deposited the mortgage amount in court under s. 83 of the Transfer of Property Act and then instituted Title Suit No. 69 of 1944 for redemption. Meantime the reversioners, the respondents herein, had filed Title suit No. 126 of 1943 for a declaration that the sale deed in favour the appellant was not binding on the reversioners. And both the suits were tried together. The parties were at issue on several questions of fact of which the only one material at this stage is whether the sale in favour of the appellant was supported by necessity and binding on the reversioners. The District Munsif of Palamau who tried the suits held on a review of the evidence that necessity was established in respect of all the four items of consideration and that the sale was binding on the reversioners. He accordingly dismissed Title Suit No. 126 of 1943 filed by the respondents and granted a decree for redemption in Title Suit No. 69 of 1944 filed by the appellant. The respondents herein, the reversioners, preferred appeals against both the decrees passed by the District Munsif of Palamau and they were heard by the Subordinate Judge of Palamau, who, agreeing with the findings given by the District Munsif, affirmed the decrees and dismissed the appeals. Against these decrees, the respondents preferred Second Appeals Nos. 2155 and 2156 of 1948 in the High Court of Patna. While these appeals were pending, Laung Kuer died on March 14, 1952, and on the application of the respondents, the plaint in Title Suit No. 126 of 1943 was amended by adding reliefs for possession and mesne profits. The appeals were then heard by a Bench consisting of Rai and Misra, JJ., who in separate but concurring judgments, held that the sale deed in favour of the appellant was not binding on the reversioners. Misra, J., who delivered the leading judgment did not disagree with the finding of the courts below that all the four items of consideration were supported by necessity. Indeed, being a finding of fact, it would be binding on the court in Second Appeal. He, however, held, following the decision in Dasrath Singh v. Damri Singh 8 Pat. L.T. 314; : AIR1927Pat219 that a widow cannot by selling properties subject to usufructuary mortgage jeopardise the right of the reversioners to redeems, and that, therefore, the sale would not be binding on them. A different view was taken in Lala Ram Asre Singh v. Ambica Lal 2 Pat. L.T. 6; A.I.R. 1929 Pat. 216, where it was held that a widow was not debarred from selling properties subject to mortgage where there was necessity for it merely by reason of the fact that they were subject to usufructuary mortgage which contained no personal covenant to pay. But the learned Judge declined to follow this decision and stated the reason thus :
'Following, therefore, the settled practice of this Court as laid down in a number of decisions, the only course left open to us in the circumstances would be either to follow the previous Division Bench Ruling in preference to the later or to refer the case to a larger Bench for settling the position. In my opinion, however, the present case is not one in which it is desirable to refer this case to a larger Bench. Following, therefore, the authority of this Court in Dasrath Singh's case which completely covers the present case, it must be held that the courts below were in error in relying upon the decision in Lala Ram Asre Singh's case.'
3. In the result the learned Judge held that the sale deed in favour of the appellant dated June 17, 1943, was not binding on the reversioners. Rai, J., expressed the view that as the bona fides of the sale in favour of the appellant was questioned by the reversioners and as there had been no finding on that point by the Subordinate Judge, the matter might have to be remanded for a finding on that question, but that, as the sale deed was not supported by necessity, he agreed with the conclusion of Misra, J. The Second Appeals were accordingly allowed and consequential reliefs granted. Thereafter, the appellant applied in the High Court under Art. 133 for leave to appeal to this court, and in granting certificates. Ramaswami, C.J., and Raj Kishore Prasad, J., observed in their Order dated November 27, 1956, that there being a conflict between the decisions in Dasrath Singh's case 8 Pat. L.T. 314; : AIR1927Pat219 and Lala Ram Asre Singh's case [11 Pat. L.T. 6; A.I.R. 1929 Pat. 216, the point was one of sufficient importance for grant of leave to appeal to this Court. They also stated that the question as to the practice to be followed, when there was a conflict of decisions, was likewise one of public importance, which ought to be settled by this Court. They accordingly granted certificates under Art. 133(1)(c) and that is how these appeals come before us.
4. Before considering the two questions referred to in the order of the High Court granting certificates, we shall deal with a contention raised on behalf of the respondents, which if well founded would necessitate a remand of these appeals. It was argued that the sale deed in favour of the appellant was not bona fide, that it had been so held by the District Munsif, but that the Subordinate Judge had failed to record a finding on this question, and that therefore there should be a remand for a decision on that point. As already stated, Rai, J., appears to have been impressed by this contention. But when the contention is further examined it will be found to be wholly without substance. What the District Munsif said was that 'after the death of Prithi Dubey the relatives of Lawan Kuer had fallen on her property like vultures', and that it was quite possible 'that the transaction in question was also brought at their instance and they were also benefited by it.' This only means that the relatives of Laung Kuer were guilty of spoliation of the estate. But that would not affect the rights of the appellant unless he was a party to it, which, however, is not the case, and that is what the District Munsif himself observes with reference to this aspect :
'But in the present suit I have got to consider the interest of Jaisri Sahu who has in good faith already paid Rs. 500 to the Mostt. and has deposited the balance of Rs. 1,100 in court for the redemption of the Zarpeshgi.'
5. This finding that the appellant himself acted bona fide was not challenged before the Subordinate Judge on appeal and the point is accordingly not open to the respondents.
6. Dealing next with the points mentioned in the Order of the High Court dated November 27, 1956, the first question that arises for decision is whether a sale by a widow of properties which are the subject matter of a usufructuary mortgage is beyond her powers when the mortgagee cannot sue to recover the amount due on the mortgage. This has been answered in the affirmative by the learned Judges of the High Court on the strength of the decision in Dasrath Singh v. Damri Singh 8 Pat. L.T. 314; : AIR1927Pat219 . There the last male holder, one Sitaram Singh, had created a usufructuary mortgage, and after his death the widow sold the property for the discharge of this debt and of certain other debts, and for meeting the marriage expenses of her daughter and grand-daughter. It was held by Das and Adami, JJ., that all these items of consideration were supported by necessity, but nevertheless the sale was not binding on the reversioners. Das, J., who delivered the judgment observed as follows :-
'It is contended that under the terms of the usufructuary mortgage it would be open now to the plaintiffs to redeem that mortgage and it is pointed out that their right to redeem should not have been jeopardised by the widow by the transfer of the property to the mortgagee. In my opinion this argument is right and should prevail.'
7. If the learned Judge intended to lay down as an inflexible proposition of law that, whenever there is a usufructuary mortgage, the widow cannot sell the property, as that would deprive the reversioners of the right to redeem the same, we must dissent from it. Such a proposition could be supported only if the widow is in the position of a trustee, holding the estate for the benefit of the reversioners, with a duty cast on her to preserve the properties and pass them on intact to them. That, however, is not the law. When a widow succeeds as heir to her husband, the ownership in the properties, both legal and beneficial, vests in her. She fully represents the estate, the interest of the reversioners therein being only spes successionis. The widow is entitled to the full beneficial enjoyment of the estate and is not accountable to any one. It is true that she cannot alienate the properties unless it be for necessity or for benefit to the estate, but this restriction on her powers is not one imposed for the benefit of reversioners but is an incident of the estate as known to Hindu law. It is for this reason that it has been held that when Crown takes the property by escheat it takes it free from any alienation made by the widow of the last male holder which is not valid under the Hindu law, vide : Collector of Masulipatam v. Cavaly Venkata (1861) 8 M.I.A. 529. Where, however, there is necessity for a transfer, the restriction imposed by Hindu law on her power to alienate ceases to operate, and the widow as owner has got the fullest discretion to decide what form the alienation should assume. Her powers in this regard are, as held in a series of decisions beginning with Hanooman Persaud v. Mussamat Babooee (1856) 6 M.I.A. 393, those of the manager of an infant's estate or the manager of a joint Hindu family. In Venkaji v. Vishnu (1894) 18 Bom. 534 it was observed that -
'A widow like a manager of the family, must be allowed a reasonable latitude in the exercise of her power, provided,.......'she acts fairly to her expectant heirs'.'
8. And more recently, discussing this question, it was observed in Viraraju v. Venkataratnam I.L.R.  Mad. 226 :-
'How exactly this obligation is to be carried out, whether by a mortgage, sale or other means, is not to be determined by strict rules or legal formulae, but must be left to the reasonable discretion of the party bound. In the absence of mala fides or extravagance, and so long as it is neither unfair in character nor unreasonable in extent, the Court will not scan to nicely the manner or the quantum of the alienation.'
9. Judged by these principles, when there is a mortgage subsisting on the property, the question whether the widow could sell it in discharge of it is a question which must be determined on the facts of each case, there being no absolute prohibition against her effecting a sale in a proper case. What has to be determined is whether the act is one which can be justified as that of a prudent owner managing his or her own properties. If the income from the property has increased in value, it would be a reasonable step to take to dispose of some of the properties in discharge of the debt and redeem the rest so that the estate can have the benefit of the income. In this view, the decision in Dasrath Singh's case 8 Pat. L.T. 314; : AIR1927Pat219 in so far as it held that a sale by a widow of a property which is subject to a usufructuary mortgage is not binding on the reversioners must be held to be wrong.
10. In Lala Ram Asre Singh's case F11 Pat. L.T. 6; A.I.R. 1929 Pat. 216, which was a decision of Das and Fazl Ali, JJ., the facts were similar to those in Dasrath Singh's case 8 Pat. L.T. 314; : AIR1927Pat219 . Dealing with the contention that a sale by the widow of properties which were the subject-matter of a Zerpeshgi deed was not binding on the reversioners because the Zerpeshgidar was in possession of the properties and he could not sue to recover the amount due thereunder, Das, J., delivering the judgment of the court observed :-
'This in my view is an impossible argument. The debt was there; it was a subsisting debt, only the creditor was in possession of a part of the estate and was unable to recover it by instituting a suit in the civil courts. But the result was that a considerable portion of the income was withdrawn from Basmati Kuer who had succeeded her husband. It is well-established that where a case of necessity exists, an heiress is not bound to borrow money, with the hope of paying it off before her death. Nor is she bound to mortgage the estate, and thereby reduce her income for life. She is at liberty, if she thinks fit, absolutely to sell off a part of the estate.'
11. In our judgment these observations correctly state the position in law. It will be noticed that Das, J., delivered the judgment in both Dasrath Singh's case 8 Pat. L.T. 314; : AIR1927Pat219 and Lala Ram Asre Singh's case 11 Pat. L.T. 6; A.I.R. 1929 Pat. 216 and that the decision in Dasrath Singh's case 8 Pat. L.T. 314; : AIR1927Pat219 is not referred to in the judgment in Lala Ram Asre Singh's case 11 Pat. L.T. 6; A.I.R. 1929 Pat. 216.
12. It has been found in this case that Laung Kuer had to raise a sum of Rs. 500 for necessary purposes. She could have done that by mortgaging other properties, but that would have reduced the income available for enjoyment by her. On the other hand, by a sale of a portion of the properties covered by the Zerpeshgi deed dated June 21, 1935, she was able to redeem the other properties and the estate had the benefit of the income from those properties. The District Munsif and the Subordinate Judge on appeal have both of them held on a review of all the facts that the sale in favour of the appellant is a proper one binding on the reversioners. We are of opinion that this finding is not open to attack in Second Appeal.
13. Then there is the question of the practice to be followed when there is a conflict among decisions of Benches of the same High Court. When a Bench of the High Court gives a decision on a question of law, it should in general be followed by other Benches unless they have reasons to differ from it, in which case the proper course to adopt would be to refer the question for the decision of a Full Bench. In Buddha Singh v. Laltu Singh I.L.R(1915) . 37 All. 604, the Privy Council had occasion to discuss the procedure which should be adopted when a Bench of a High Court differs from the opinion given by a previous Bench. After referring to Suraya Bhukta v. Lakhshminarasamma I.L.R(1881) . 5 Mad. 291 and Chinnasami Pillai v. Kunju Pillai I.L.R(1912) . 35 Mad. 152, where decisions had been given based on the opinions expressed by Devananda Bhatta in the Smriti Chandrika, the Privy Council observed :-
'Curiously enough there is no reference in either of the Madras judgments referred to above to a previous decision, Parasara Bhattar v. Rangaraja Bhattar (1880) I.L.R. 2 Mad. 2 of the same court to which Turner, C.J., was also a party. In that case the rule of the Smriti Chandrika was not accepted nor was the literal construction of the Mitakshara followed. It is usual in such cases where a difference of opinion arises in the same court to refer the point to a Full Bench, and the law provides for such contingencies. Had that course been followed their Lordships would probably have had more detailed reasoning as to the change of opinion on the part at least of one Judge.' (pp. 622, 623).
14. Considering this question, a Full Bench of the Madras High Court observed in Seshamma v. Venkata Narasimharao Mad. I.L.R.  454 :
'The Division Bench is the final Court of appeal in an Indian High Court, unless the case is referred to a Full Bench, and one Division Bench should regard itself bound by the decision of another Division Bench on a question of law. In England, where there is the Court of Appeal, Divisional Courts follow the decisions of other Divisional Courts on the grounds of judicial comity; see The Vera Cruz (No. 2) (1884) 9 P.D. 96, Harrison v. Ridgway (1925) 133 L.T. 238, Ratkinsky v. Jacobs  1 K.B. 24 and Phillips v. Copping  1 K.B. 15. If a Division Bench does not accept as correct the decision on a question of law of another Division Bench the only right and proper course to adopt is to refer the matter to a Full Bench, for which the rules of this court provide. If this course is not adopted, the courts subordinate to the High Court are left without guidance. Apart from the impropriety of an appellate Bench refusing to regard itself bound by a previous decision on a question of law of an appellate Bench of equal strength and the difficulty placed in the way of subordinate Courts administering justice, there are the additional factors of the loss of money and the waste of judicial time.'
15. Law will be bereft of all its utility if it should be thrown into a state of uncertainty by reason of conflicting decisions, and it is therefore desirable that in case of difference of opinion, the question should be authoritatively settled. It sometimes happens that an earlier decision given by a Bench is not brought to the notice of a Bench hearing the same question, and a contrary decision is given without reference to the earlier decision. The question has also been discussed as to the correct procedure to be followed when two such conflicting decisions are placed before a later Bench. The practice in the Patna High Court appears to be that in those cases, the earlier decision is followed and not the later. In England the practice is, as noticed in the judgment in Seshamma v. Venkata Narasimharao I.L.R.  Mad. 454, that the decision of a Court of Appeal is considered as a general rule to be binding on it. There are exceptions to it, and one of them is thus stated in Halsbury's Laws of England, third edition, Vol. 22, para. 1687, pp. 799, 800 :-
'The court is not bound to follow a decision of its own if given per incuriam. A decision is given per incuriam when the court has acted in ignorance of a previous decision of its own or of a court of a co-ordinate jurisdiction which covered the case before it, or when it has acted in ignorance of a decision of the House of Lords. In the former case it must decide which decision to follows, and in the latter it is bound by the decision of the House of Lords.'
16. In Virayya v. Venkata Subbayya : AIR1955AP215 it has been held by the Andhra High Court that under the circumstances aforesaid the Bench is free to adopt that view which is in accordance with justice and legal principles after taking into consideration the views expressed in the two conflicting Benches, vide also the decision of the Nagpur High Court in Bilimoria v. Central Bank of India A.I.R. 1943 Nag 340 The better course would be for the Bench hearing the case to refer the matter to a Full Bench in view of the conflicting authorities without taking upon itself to decide whether it should follow the one Bench decision or the other. We have no doubt that when such situations arise, the Bench hearing cases would refer the matter for the decision of a Full Court. In the result these appeals are allowed and the decrees passed by the trial court restored with costs throughout. One set of hearing costs.
17. Appeals allowed.
