It hos been ,further laid dowill that the power if interference under Art. 227 wus limited to seeing that the tribunals function within the limits of their authority and that the HiW1 Courts ,cannot sit in appeal against the order of a tribunal in, a petic tion under Art, 227. In our opinion, the High Court in this case cannot be considered to have exceeded its jurisd1cticm under Art. 227 of the Constitution. We !:ave already, stated that all findings on material facts have been accepted by the High Court. It is only on two material aspects which affect the jurisdiction of the revenue tribunals to grant the necessary t·e!ief undi:r the Act, that the High Court differed. Those were : (i) the power D of the mother on the facts found by the tribunals .to grant the lease on behalf of her minor daughter and its legal effect; and (ii) the maintainability of the application of the appeliant under s. 39 of the Act. Therefore, we cannot accept the contention of Mr. Sanghi that any error has been committed Ly the High Court in considering these aspects in proceedings under Art. 227. E The nature of the relief that could be granted to the appellant under the Act depends upon the question whether the tenancy in this case has been created "not earlier than the first day of April, 1957." There is no controversy that the appellant was not owning lands exceeding a family holding. If the tenancy in favour of the tenant in this case is one created "not earlier than F the first day of April, 1957" and if the other conditions mentioned in s. 39 are Htisfied, relief could be granted to the appellant under that section. We have already referred to ·the facts that the appellant's application was under s. 36 read with s. 39. In order to find out whether the lease in this case is one created "not earlier than the lint day of April G 1957", it is really necessary to inquire ·about tlie legal effect of the lease executed by the mother as guardian of the appellant on February 12, 1956 for the year 1956-57. If that lease is valid and binding on the appellant, the result will be th:it s. 39 will not be attracted. Therefore, we will first consider the question as to the legal effect of the lease granted by the mother, which is the subject of the second contention raised by Mr. Sanghi. Mr. H Sanghi· urged that on the findings of all the revenue tribunals and (I) [1958] S.C.R. 1240. (l) Civil Appeal No. 35 of 1966, decided on March 17, 1966.
