Summarize the following court judgment. ivil Appeal No. 1582 of 1973. From the Judgment and Order dated 27.3.72 of the Bombay High Court in Appeal No. 983 of 1966. S.B. Bhasme and V.N. Ganpule for the Appellants. Mrs. C.K. Sucharita for the Respondents. The Judgment of the Court was delivered by SAIKIA	 J. This plaintiffs ' appeal by special leave is from the Judgment of the High Court of Bombay in Second Appeal No. 983 of 1966 setting aside the Judgment of the courts below and remanding the case to the trial court for hearing with a direction to refer the issue regarding tenan cy to the tenancy authorities. The appellants are the owners of land bearing R.S. No. 1442 and 1445	 situate at Kasba Karvir	 within the municipal limits of Kolhapur. The said land was leased out to the father of respondent Nos. 1 and 2 and the husband of re spondent Nos. 3 and 4 on October 12	 1950 for a period of ten years. The appellants had filed Revision Civil Suit No. 298 of 1964 against the respondents for possession thereof	 mesne profits and for damages. It was averred in the plaint that the appellants had earlier initiated proceedings under the Bombay Tenancy and Agricultural Lands Act	 1948	 herein after referred to as 'the Act '	 and in the said proceedings it was held that the provisions of the Act were not applica ble to the land inasmuch as only grass grew thereon natural ly. It was further averred that on expiry of the period of lease the 5 appellants terminated the tenancy under the provisions of the Land Revenue Code and filed the aforementioned suit. The respondent Nos. 1 & 2 contested the suit contending	 inter alia	 that the civil court had no jurisdiction inasmuch as the Act was applicable to the land; and that they having not been in wrongful possession thereof	 the notice of termina tion was invalid. The learned trial court tried the issues regarding the applicability of the Act	 jurisdiction of the civil court	 and estoppel	 out of the issues framed	 as preliminary issues and by order dated March 16	 1965 fixed the date for hearing of the other issues and on that date the respondent Nos. 1 & 2 being absent	 after recording the appellants evidence	 by Judgment dated July 17	 1965 decreed the suit in favour of the appellants. The respondents ' appeal therefrom having been dismissed by the District Judge	 they took Second Appeal No. 983 of 1966 to the High Court of Bombay	 and the learned Single Judge has set aside the Judgment of the trial court as affirmed by the lower appellate court	 and remanded the case back to the trial court with a direction that it should raise the necessary issues on the pleadings of the parties and should make a reference to the competent authority under section 85A of the Act with respect to those issues which are required to be decid ed by the competent authority under the Act and on receipt of the findings	 dispose of the suit according to law. The appellants ' application for leave to appeal under the Let ters Patent having been rejected by the High Court	 they have obtained special leave to appeal. Mr. S.B. Bhasme	 the learned counsel for the appellants submits	 inter alia	 that the appellants ' application under section 29(2) read with section 25(2) of the Act	 being case No./84 of 1962 63 having been dismissed by the tenancy authorities on the ground that only natural grass grew thereon and there fore the authority had no jurisdiction to deliver possession thereof under section 29(2) of the Act	 that finding should act as res judicata	 wherefore	 remitting of the case by the High Court to the trial court for hearing and deciding after making a reference to the competent authority	 under section 85A of the Act with respect to those issues which are required to be decided by the competent authority under the Act	 would be barred; and that in the facts and circumstances of the case the civil court itself has jurisdiction to decide the issues which have been directed to be referred to the civil court. Mrs. C.K. Sucharita	 the learned counsel for the re spondents submits that under section 85A in a civil suit involv ing any issues which are required to be decided or dealt with by any authority competent to settle or decide such issues under the Act	 the civil court is to settle the 6 issues and refer those to such competent authority for determination; that the High Court 's direction in the im pugned Judgment is consistent with this provision; and that the appellant 's earlier proceedings under the Act before the tenancy authority having been dismissed ex parte	 it could not operate as res judicata. The question to be decided	 therefore	 is whether the High Court was correct in directing the trial court to refer the issues relating to tenancy to the competent authority under the Act. To decide it	 we may conveniently refer to the relevant provisions of the Act. The Act has amended the law which governs the relations of landlords and tenants of agricultural lands. As defined in section 2(8) of the Act	 "land" means (a) land which is used for agricultural purposes or which is so used but is left fallow	 and includes the sites of farm buildings appurtenant to such land. This definition is as amended by Bom. 15 of 1957. The amendment is not material for the purpose of our case. As defined in section 2(1)	 "Agriculture" includes horticulture	 the raising of crops	 grass or garden produce	 the use by an agriculturist of the land held by him or a part thereof for the grazing of his cattle	 the use of any land	 whether or not an appanage to rice or paddy land	 for the purpose of rab manure but does not include allied pursuits	 or the cutting of wood only. This definition is after amendments by Bom. 13 and 15 of 1956 and 1957	 respectively. As defined in section 2(2)	 "Agri culturist" means a person who cultivates land personally. As defined in section 2(5)	 "to cultivate" with its grammatical variations and cognate expressions means to till or husband the land for the purpose of raising or improving agricultur al produce	 whether by manual labour or by means of cattle or machinery	 or to carry on any agricultural operations thereon; and the expression "un cultivated" shall be con strued correspondingly. The explanation thereunder says: A person who takes up a contract to cut grass	 or to gather the fruits or other produce of trees on any land	 shall not on that account only be deemed to cultivate such land. This definition is as substituted by Bom. 13 of 1956. As defined in section 2(17)	 "Tenancy" means the relationship of landlord and tenant; and as defined in section 2(18)	 "tenant" means a person who holds land on lease and includes (a) a person who is deemed to be a tenant under section 4; (b) a person who is a protected tenant; and (c) a person who is a permanent ten ant; and the word "landlord" shall be construed accordingly. This definition is as substituted by Bom. 13 of 1956. The High Court has found that the appellants had leased out the land on October 12	 1950 for a period of 10 years under a Kabulayat at 7 an annual rental of Rs. 1000 and that period expired on October 11	 1960. The appellants submitted an application under section 29(2) of the Act	 being case No. 2068 of 1957 but that application was dismissed. Thereafter	 they moved another application under section 88C of the Act being case No. 285 of 1961 and that application was also dismissed on the ground that the lands were governed by section 43C of the Act	 but the Act did not apply as the lands were within the limits of the municipal borough. Thereafter	 they started the third proceeding being application under section 29(2) read with section 25(2) of the Act being case No. 184 of 1962 63. That application also came to be dismissed by the tenancy author ities on the ground that the lands in dispute were lands growing natural grass and	 therefore	 the authority under the Act had no jurisdiction to deliver possession under section 29(2) of the Act. The High Court noticed that the applica tion was decided ex parte but the Court did not know under what circumstances	 the competent authority proceeded ex parte. The effect of that decision was that the application filed by the appellants as landlords for possession of the lands treating the opponents thereof as tenants was dis missed. It was only thereafter that the appellants served the respondents with a notice terminating the tenancy and demanding possession	 and the defendants having not complied with the notice	 the appellants filled the instant suit	 Considered in the light of the above definitions and the provisions of section 85A of the Act there arises no doubt that some of the issues involved in the suit may be such as have necessarily to be decided by the competent authority under the Act and to that extent the jurisdiction of the civil court to decide those issues may be excluded. In Shivappa Satawappa Ashtekar vs Gajanan Chintaman Desh Pande	 [1953] 55 Bombay Law Reporter Bombay 107	 in the landlord 's suit for possession of lands filed in civil court	 the defendants having contended that the lands were agricultural lands and that the defendants were pro tected tenants	 interpreting the then section 85(1) it was held: "Ex facie	 by the operation of section 70 and section 85 of the Bombay Tenancy and Agricultural Lands Act	 1948	 the jurisdiction of the civil court to decide whether the defendants were tenants or protected tenants must be regarded as excluded and the Mamlatdar alone must be regarded as competent to decide that question. That is the view which has been taken by a division bench of this Court in Dhondi Tukaram vs Dadoo Piraji	 8 Section 70(b) of the Act then provided: "For the purposes of this Act the following shall be the duties and functions to be performed by the Mamlatdar: (a) . . . (b) to decide whether a person is a tenant or a protected tenant." Section 85(1) provided: "No Civil Court shall have jurisdiction to settle	 decide or deal with any question which is by or under this Act required to be set tled	 decided or dealt with by the Mamlatdar or Tribunal	 a Manager	 the Collector or the Bombay Revenue Tribunal in appeal or revision or the State Government in exercise of their powers of control. " This Court in Bhimaji Shanker Kulkarni vs Dundappa Vithappa Udapudi and Anr.	 ; 	 considering the decision in Dhondi Tukaram 's case (supra) which held that the Mamlatdar had exclusive jurisdiction to decide those issues though they arose for decision in a suit properly cognisable by a civil court	 observed: "The result was somewhat startling	 for nor mally the Civil Court has jurisdiction to try all the issues arising in a suit properly cognisable by it. But having regard to the fact that the Bombay Legislature approved of Dhondi Tukaram 's case and gave effect to it by introducing section 85A	 we must hold that the decision correctly interpreted the law as it stood before the enactment of section 85A. It follows that independently of section 85A and under the law as it stood before section 85A came into force	 the courts below were bound to refer to the Mamlatdar the decision of the issue wheth er the defendant is a tenant. " Section 70 of the Act now provides: "For the purposes of this Act the following shall be the duties and functions to be per formed by the Mamlatdar: (a) to decide whether a person is an agricul turist; 9 (b) to decide whether a person is	 or was at any time in the past	 a tenant or a protected tenant or a permanent tenant; XXXXX XXXXX XXXXX XXXXX XXXXX XXXXX (n) to take measures for putting the tenant or landlord or the agricultural labour er or artisan or person carrying on as allied pursuit into the possession of the land or dwelling house under this Act; (o) to decide such other matters as may be referred to him by or under this Act." The words "person is	 or was at any time in the past	 a tenant"	 and the words "or a permanent tenant" were substi tuted for the words "person is a tenant" by Mah. 49 of 1969. Section 85 and section 85A as inserted by Bombay Act 13 of 1956 provide: 85. (1) No Civil Court shall have jurisdiction to settle	 decide or deal with any question including a question whether a person is or was at any time in the past a tenant and whether any such tenant is or should be deemed to have purchased from his landlord the land held by him which is by or under this Act required to be settled	 decided or dealt with by the Mamlatdar or Tribunal	 a Manager	 the Collector or the Maharashtra Revenue Tribunal in appeal or revision or the State Government in exercise of their powers of control. (2) No order of the Mamlatdar	 the Tribunal	 the Collector or the Maharashtra Revenue Tribunal or the State Government made under this Act shall be questioned in any Civil or Criminal Court. Explanation For the purposes of this section a Civil Court shall include a Mamlatdar 's Court constituted under the Mamlatdar 's Courts Act	 1906." "85A. (1) If any suit instituted in any Civil Court involves any issues which are required to be settled	 decided or dealt 10 with by any authority competent to settle	 decide or deal with such issues under this Act (hereinafter referred to as the "competent authority") the Civil Court shall stay the suit and refer such issues to such competent authority for determination. (2) On receipt of such reference from the Civil Court	 the competent authority shall deal with and decide such issues in accordance with the provisions of this Act and shall communicate its decision to the Civil Court and such court shall thereupon dispose of the suit in accordance with the procedure applica ble thereto. Explanation For the purpose of this section a Civil Court shall include a Mamlatdar 's Court constituted under the Mamlatdar 's Courts Act	 1906. " This section was inserted by Bombay Act 13 of 1956. Before the amendment of section 70(b) by Maharashtra Act 49 of 1969	 when the question as to whether a party was in the past tenant or not for the purpose of acquiring some other right	 that is	 not as main issue but as a subsidiary issue	 Civil Court 's jurisdiction to decide such subsidiary issue could not be said to be barred. Section 70(b) of the Act imposed a duty on the Mamlatdar to decide "whether a person is a tenant" and not "whether a person was or was not a tenant in the past". In Mussamiya Imam Haider Bax Razvi vs Rabari Govindhai Ratnabhai & Ors.	 ; 	 the appellant filed a suit on July 11	 1958 for recovery of possession of the suit lands and mesne profits averring that the lease was fraudulently obtained by the respondents. The respondents contended that they became statutory owners section 32 or section 88 of the Act and the Civil Court had no jurisdic tion to decide the suit. The trial court decreed the suit and on appeal the High Court held that fraud was not proved; the respondents failed to prove that they were statutory owners before the date of the suit; that the Civil Court had jurisdiction to decide whether defendants were tenants on the relevant dates namely	 July 28	 1956 or May 11	 1958; and that the Civil Court had no jurisdiction to decide whether the defendants were tenants on date of the suit and that question was to be referred to the Mamlatdar. This Court on consideration of the provisions of section 70 and section 85A with other relevant provisions held at page 797: "We are accordingly of the opinion that section 85 read with 11 section 70 of the Act does not bar the jurisdiction of the Civil Court to examine and decide the question whether the defendants had acquired the title of statutory owners to the disputed lands under the new Act. In this context	 it is necessary to bear in mind the important principle of construction which is that if a statute purports to exclude the ordinary jurisdiction of a Civil Court it must do so either by express terms or by the use of such terms as would necessarily lead to the infer ence of such exclusion. As the Judicial Com mittee observed in Secretary of State vs Mask & Co.	 671.A. 222	236. 'It is settled law that the exclusion of the jurisdiction of the civil courts is not to be readily inferred	 but that such exclusion must either be explicitly expressed or clearly implied. ' In our opinion	 there is nothing in the lan guage or context of section 70 or section 85 of the Act to suggest that the jurisdiction of the Civil Court is expressly or by necessary implication barred with regard to the question whether the defendants had become statutory owners of the land and to decide in that connection whether the defendants had been in the past tenants in relation to the land on particular past dates. We are also of the opinion that the jurisdic tion of the Civil Court is not barred in considering the question whether the provi sions of the Act are applicable or not ap plicable to the disputed land during a partic ular period. " It may be noted that after the amendment of section 70(b) of the Act by inserting the words "or was at any time in the past	 a tenant"	 the position has changed. The Civil Court has now no jurisdiction to decide an issue arising inciden tally in a civil suit which is to be specifically decided by a competent authority under the Act. Civil Court in such a case shall refer the issue to that authority and dispose of the suit in accordance with the decision of the authority. In G.S. Shinde vs R.B. Joshi	 ; 	 the appel lant filed the suit for specific performance of a contract for sale of land dated December 15	 1965 coupled with a supplementary agreement dated April 26	 1966 for sale of agricultural land. The suit was resisted by the defendant	 contending	 inter alia	 that the provisions of the Act were applicable to the land and the appellant not being an agri culturist	 section 63 of the Act was a bar to his purchase of the land	 and the agreement being contrary to law could not be specifically enforced. The plaintiff (appellant) sought 12 to repel that contention by producing a certificate	 Ext. 78	 issued by the Mamlatdar certifying that the plaintiff was an agricultural labourer and the bar of section 63 was not operative. If that Ext. 78 was not taken note of	 the issue would arise whether the plaintiff was an agriculturist and in view of the provisions section 70(a) read with section 85 and section 85A of the Act	 the issue would have to be referred to the Mamlatdar for decision as the civil court would have no jurisdiction to decide the issue. The trial court and the High Court held that Ext. 78 had no evidentiary value and the issue whether the plaintiff was an agriculturist being an incidental issue	 main issue being that of specific performance	 Civil Court had jurisdiction. Allowing the appeal therefrom and remanding the suit to the trial court this Court speaking through Desai	 3. held at para 10: "Now	 if Section 85 bars the jurisdiction of the Civil Court to decide or deal with an issue arising under the Tenancy Act and if Section 85A imposes an obligation on the Civil Court to refer such issue to the competent authority under the Tenancy Act	 it would be no answer to the provisions to say that the issue is an incidental issue in a properly constituted civil suit before a Civil Court having jurisdiction to entertain the same. In fact Section 85A comprehends civil suits which Civil Courts are competent to decide but takes note of the situation where upon a contest an issue may arise therein which would be re quired to be settled	 decided or dealt with by the competent authority under the Tenancy Act	 and	 therefore	 it is made obligatory for the Civil Court not only not to arrogate jurisdic tion to itself to decide the same treating it as a subsidiary or incidental issue	 but to refer the same to the competent authority under the Tenancy Act. This is an inescapable legal position that emerges from a combined reading of Sections 85 and 85A . . . . In a civil suit nomenclature of the issue as principal or subsidiary or substantial or incidental issue is hardly helpful because each issue	 if it arises	 has to be determined to mould the final relief. Further	 Sections 85 and 85A oust jurisdiction of Civil Court not in re spect of civil suit but in respect of ques tions and issues arising therein and Section 85A mandates the reference of such issues as are within the competence of the competent authority. If there is an issue which had to be settled	 decide or dealt with by competent authority under the Tenancy Act	 the jurisdic tion of the Civil Court	 13 notwithstanding the fact that it arises in an incidental manner in a civil suit	 will be barred and it will have to be referred to the competent authority under the Tenancy Act. By such camouflage of treating issues arising in a suit as substantial or incidental or princi pal or subsidiary	 Civil Court cannot arrogate to itself jurisdiction which is statutorily ousted. This unassailable legal position emerges from the relevant provisions of the Tenancy Act." After considering the precedents in Trimbak Sopana Girme vs Gangaram Mhatarba Yadav	 1953 Bom. 241; Dhondi Tukaram Mali	 (supra); Bhimaji Shanker Kulkarni	 (supra); Ishwerlal Thakorelal Almaula vs Motibhai Nagjibhai	 [1966] 1 SCR 367=AIR 1966 SC 459; Pandurang Hari Jadhav vs Shankar Maruti Todkar	 ; Kalicharan Bhajan lal Bhayya vs Rai Mahalaxmi	 ; Neminath Appayya Hanammannaver vs Jambu Rao Satappa Kocheri	 AIR ; Jarnbu Rao Satappa Kocheri vs Neminath Appayya Hanamrnannaver	 ; 1968 SC 1358; Mussamiya Imam	 (supra) and Noor Mohd; Khan Ghouse Khan Soudagar vs Fakirappa Bharmappa Machenahalli. ; 3 SCR 789	 their Lordships observed at para 19: "Thus	 both on principle and on authority there is no escape from the conclusion that where in a suit properly constituted and cognizable by the Civil Court upon a contest an issue arises which is required to be set tled	 decided or dealt with by a competent authority under the Tenancy Act	 the jurisdic tion of the Civil Court to settle	 decide or deal with the same is not only ousted but the Civil Court is under a statutory obligation to refer the issue to the competent authority under the Tenancy Act to decide the same and upon the reference being answered back	 to dispose of the suit in accordance with the decision of the competent authority under the Tenancy Act. " In the instant case	 applying the settled law as enunciated above	 and in view of the certainty of the questions in volved	 we are of the view that the High Court has rightly sent back the suit to the trial court with the direction to refer issues	 if raised any	 to be determined exclusively by the competent authority	 to that authority. We now deal with the submission of Mr. Bhasme that the order 14 of the tenancy authority in case No. 184 of 1962 63 dismiss ing his application under section 29(2) read with section 25(2) of the Act holding that it had no jurisdiction to deliver posses sion of the land on the ground that the natural grass grew thereon	 should act as res judicata	 wherefore	 referring of issues to the Mamlatdar in the suit remitted by the High Court would be barred. Counsel submits that the Mamlatdar in deciding the aforesaid application acted under the Mamlat dar 's Courts Act	 1906 (Bom. Act No. II of 1906) and would be a Court competent to determine the issue as to whether the act was applicable to the appellants ' land under the lease	 and it already decided that the Act was not applica ble as on that land only natural grass grew	 which meant that it was not 'land ' and the defendants were not 'tenants ' as defined in the Act. Section 11 of the C.P.C. which deals with res judicata provides: "No Court shall try any suit or issue in which the matter. directly and substantially in issue has been directly and substantially in issue in a former suit between the same par ties	 or between parties under whom they or any of them claim	 litigating under the same title	 in a Court competent to try such subse quent suit or the suit in which such issue has been subsequently raised	 and has been heard and finally decided by such Court." (Explanations I to VIII are not so relevant for the purpose of this case) In Duchess of Kingston 's case Sir William de Grey said: "From the variety of cases relative to judg ments being given in evidence in civil suits	 these two deductions seem to follow as gener ally true: first that judgment of a court of concurrent jurisdiction	 directly upon the point	 is	 as a plea	 a bar	 or as evidence conclusive between the same parties	 upon the same matter	 directly in question in another Court; secondly that the judgment of a Court of exclusive jurisdiction	 directly on the point	 is	 in like manner	 conclusive upon the same matter	 between the same parties	 coming incidentally in question in another Court	 for a different purpose. But neither the judgment of a Court	 of concurrent or exclusive juris diction is evidence of any matter which came collaterally in question	 though within their jurisdiction nor of any matter incidentally 15 cognizable	 nor of any matter to be inferred by argument from the judgment. " Section 11 bars the trial of a suit or issue in which the matter directly and substantially in issue has already been adjudicated upon in a previous suit. This Section applies in terms to cases where the matter in issue in a subsequent 'suit ' was an issue in a "former suit". A 'suit ' is a proceeding which is commenced by a plaint. As provided in Section 26 of the C.P.C. every suit shall be instituted by the presentation of a plaint or in such other manner as may be prescribed. In the instant case admittedly the appel lants submitted an application to the Mamlatdar under section 29(2) read with section 25(2) of the Act. Sub section (2) of section 29 provides: "Save as otherwise provided in sub section (3A)	 no landlord shall obtain possession of any land or dwelling house held by a tenant except under an order of the Mamlatdar. For obtaining such order he shall make an applica tion in the prescribed form and within a period of two years from the date on which the right to obtain possession of the land or dwelling house	 as the case may be	 is deemed to have accrued to him." This sub section is as amended by Mah. 39 of 1964. It does not speak of a plaint	 a suit or a decree. The appellants did not call its application a plaint or the case a suit. If a matter directly and substantially in issue in a former suit has been adjudicated upon by a Court of exclu sive jurisdiction	 the adjudication will bar the trial of the same matter in a subsequent suit. In the instant case the Mamlatdar having decided the appellants ' application for possession	 the appellants themselves went to the Civil Court and filed the suit. It does not now lie in their mouth to say that the decision of the Mamlatdar would act as res judicata for the trial court. We have seen that now the Mamlatdar 's Court is a Civil Court for the purpose of section 85A of the Act. It is true that section 11 is now made applicable by the Explanations and interpretation to certain proceedings giving more extensive meaning to the word 'suit '. In its comprehensive sense the word 'suit ' is understood to apply to any proceeding in a court of justice by which an individ ual pursues that remedy which the law affords. The modes of proceedings may be various but that if a right is litigated between 16 parties in a court of justice the proceeding by which the decision of the Court is sought may be a suit. But if the proceeding is of a summary nature not failing within the definition of a suit	 it may not be so treated for the purpose of section 11. In the absence of the details of the proceeding concerned in the instant case	 it has not been possible for us to hold that it was of the nature of a suit and not a summary proceeding. Besides	 assuming the Mamlat dar in deciding the application in 1962 63 to have been a court of exclusive jurisdiction for the purpose of section 11 C.P.C.	 its decision rejecting the application would not be an evidence on the question of tenancy merely because it could be inferred from that decision. Admittedly the appellants ' application was decided ex parte. It is true that ex parte decrees operate to render the matter decided res judicata	 and the defendants ' failure to appear will not deprive the plaintiff of the benefit of his decree. But in the case of a suit in which a decree is passed ex parte	 the only matter that can be 'directly and substantially in issue ' is the matter in respect of which relief has been claimed by the plaintiff in the plaint. A matter in respect of which no relief is claimed cannot be 'directly and substantially in issue ' in a suit in which a decree is passed ex parte though the Court may have gone out of its way and declare the plaintiff to be entitled to relief in respect of such matter. In the instant case apply ing the above principle the order having been passed ex parte	 assuming the doctrine of res judicata applied	 it could be only to the extent of the appellants having been not entitled to possession at the relevant time; and it could not be extended logically to the issue whether the defendants were tenants under the Act. The expression 'heard and finally decided ' in section 11 means a matter on which the court has exercised its judicial mind and has after argument and consideration come to a decision on a contested matter. It is essential that it should have been heard and finally decided. What operates as res judicata is the ratio of what is fundamental to the decision but it cannot be ramified or expanded by logical extension. In Vithal Yaswant vs Shikandar Khan Mutumukhtan	 ; 	 it has been held by this Court that when a court bases its decision on more than one point	 each of which would by itself be sufficient for the ultimate deci sion	 the decision on each one of those points would be res judicata. In the instant case what were the points specifi cally urged and decided are not clear. In Pandurang Mahadeo Kavade & Ors. vs Annaji Balwant Bokil & Ors.	 it was held that in order to operate as res judicata it must be established that the previous 17 decision was given by a court which had jurisdiction to try the present suit	 and there would be no res judicata if the previous decision was by a court having no jurisdiction. Of course that was a case of pecuniary jurisdiction	 but there is no reason why the same principle should not apply in other cases of courts without jurisdiction. The law is well settled that a court which had no jurisdiction to try a cause cannot by its own erroneous decision confer on itself competence to decide it and its decision on the question of jurisdiction cannot operate as res judicata. Conversely the decision relating to jurisdiction cannot be said to consti tute the bar of res judicata where by an erroneous interpre tation of a statute it holds that it has no jurisdiction. It is stated that there was no appeal filed by the defendants from the order of the Mamlatdar. That is not material. In Ramchandra Rao vs Ramchandra Rao	 [1922] 49 I.A. 129	 the Privy Council decided that where the suit as to the title for compensation had been referred to the Court	 a decree thereon was not appealed from	 the question of title would be res judicata in a suit between the parties to the dis pute. In Bhagwan Dayal vs Mst. Reoti Devi	 ; 	 a dispute arose as to proprietary title. A suit was filed in a Revenue Court under the U.P. Tenancy Act. The Revenue Court framed an issue thereon and referred it to the Civil Court as required by the Act. The Civil Court held that the re spondent had a half share in the villages and on the basis of this finding the Revenue Court decreed his suit. Thereaf ter	 the appellant filed a suit in Civil Court for a decla ration that he was the absolute owner of all the property in the suit. The defendants contended that the suit was barred by res judicata. This Court held that a subsequent suit was not barred by res judicata by the Judgment of the Revenue Court	 as it was not within the exclusive jurisdiction of the Revenue Court and suit was maintainable in the Civil Court. The Judgment of the Revenue Court on the issue of proprietary title could not operate as res judicata as a Revenue Court was not competent to try the subsequent suit. In the instant case	 the Mamlatdar declined to exercise jurisdiction holding that the Act did not apply. If an issue is referred to it by the trial court under the Act	 the question of jurisdiction would not arise and there could be no question of res judicata as to jurisdiction of the Mam latdar on reference. Bearing in mind the above provisions and the principles of law	 we are of the view that there could arise no ques tion of res judicata in the instant case. Section 11 would not be a bar to the trial court in 18 referring issues which are to be exclusively determined by a competent authority under the Act	 to that authority. Nor should arise any such question of res judicata in the compe tent authority deciding those issues when referred to by the trial court. In the result	 we find no merit in this appeal which is accordingly dismissed	 but without any order as to costs. Y. Lal Appeal dismissed.

The appellants landlords leased out their land	 situate at Kolhapur	 to respondents Nos. 1 and 2 and the husband of respondents Nos. 3 and 4 on 12.10.1950 for a period of ten years. After the expiry of the lease period	 they initiated proceedings under the Bombay Tenancy and Agricultural Lands Act	 1948	 for obtaining possession of the lands but the application was dismissed ex parte	 as it was held that the provisions of the Act were not applicable to the land inas much as only grass grew thereon naturally. Thereupon the appellants terminated the tenancy under the provisions of the Land Revenue Code and filed a Civil Suit against the respondents for possession mesne profits and for damages. Respondents 1 and 2 contested the suit contending inter alia that the civil court had no jurisdiction to try the suit inasmuch as the Act was applicable to the land and that they having been in rightful possession	 the notice of termina tion of tenancy was invalid. The trial court tried the issues amongst others relating to the applicability of the Act	 jurisdiction of the civil court and estoppel and after going through the evidence led by the parties	 decreed the suit. The respondents appeal against the said decree having failed before the first appellate court	 they preferred Second Appeal to the High Court of Bombay. The High Court set aside the judgment and order of the trial court as affirmed by the first appellate court and remanded the case back to the trial court with a direction that it should raise the necessary issues on the pleadings of the parties and should make a reference to the competent authority under Section 85A of the Act in regard to the issues which are required 2 to be determined by the competent authority under the Act and on receipt of findings	 dispose of the suit according to law. Being dissatisfied with the said order	 the appellants moved application for leave to appeal under the Letters Patent but the same having been dismissed they have filed this appeal after obtaining special leave. The appellants ' principal contention	 amongst others	 before this court is that the appellants ' application under Section 29(2) read with section 25(2) of the Act having been dismissed on the ground that the Act was not applicable and thus the authority had no jurisdiction to deliver possession is a finding which would operate as res judicata; hence the High Court 's direction making a reference to the competent authority under section 85A of the Act	 now would be barred. According to them the civil court itself has jurisdiction to decide the issues. Respondents ' contention is that the direction of the High Court is consistent with the provi sions of the Act and that the earlier proceedings under the Act initiated by the appellants having been determined ex parte	 it could not operate as res judicata. Dismissing the appeal	 this Court	 HELD: After the amendment of section 70(b) of the Act by insert ing words 'or was at any time in the past	 a tenant ' the position has changed. The Civil Court has now no jurisdic tion to decide an issue arising incidentally in a civil suit which is to be specifically decided by a competent authority under the Act. Civil Court in such a case shall refer the issue to that authority and dispose of the suit in accord ance with the decision of the authority. [11F] (See G.S. Shinde vs R.B. Joshi	 ; ;) The High Court in the instant case has rightly sent back the suit to the trial court with the direction to refer issues	 if raised to be determined exclusively by the compe tent authority	 to that authority. [13G] If a matter directly and substantially in issue in a former suit has been adjudicated upon by a court of exclu sive jurisdiction	 the adjudication will bar the trial of the same matter in a subsequent suit. [15E] In the instant case	 the Mamlatdar having decided the appellants ' application for possession	 the appellants themselves went to the Civil Court and filed the suit. It does not now lie in their mouth to say that 3 the decision of the Mamlatdar would act as res judicata for the trial court.[15F] The Mamlatdar 's Court is a civil court for the purpose of Section 85A of the Act. [15F] In its comprehensive sense the word 'suit is understood to apply to any proceeding in a court of justice by which an individual pursues that remedy which the law affords. The modes of proceedings may be various but if a right is liti gated between parties in a court of justice the proceeding by which the decision of the court is sought may be a suit. But if the proceeding is of a summary nature not falling within the definition of a suit it may not be so treated for the purpose of Sec. 11. [15H; 16A] Besides	 assuming the Mamlatdar in deciding the applica tion in 1962 63 to have been a court of exclusive jurisdic tion for the purpose of section 11 C.P.C.	 its decision rejecting the application would not be an evidence on the question of tenancy merely because it could be inferred from that deci sion. [16B] The expression 'heard and finally decided '	 in section 11 means a matter on which the court has exercised its judicial mind and has after argument and consideration come to a decision on a contested matter. It is essential that it should have been heard and finally decided. What operates as res judicata is the ratio of what is fundamental to the decision but it cannot be ramified or expanded by logical extension. [16F G] (See Vithal Yaswant vs Shikander Khan Mutumukhtan	 ; The law is well settled that a court which had no juris diction to try a cause cannot by its own erroneous decision confer on itself competence to decide it and its decision on the question of jurisdiction cannot operate as res judicata. Conversely the decision relating to jurisdiction cannot be said to constitute the bar of res judicata where by an erroneous interpretation of a statute it holds that it has no jurisdiction.
