1. - The Income-tax Appellate Tribunal (Delhi Bench " E "), Delhi, has remitted the following question of law to this court for its decision :

"Whether, on the facts and in the circumstances of the case, the Tribunal was justified in holding that the assessee is an educational institution within the meaning of section 10(22) of the Income-tax Act, 1961, and is, therefore, not liable to be assessed under the Act ? "

2. Briefly recapitulated, the material facts are that the assessee, Maharaja Sawai Mansinghji Museum Trust, City Palace, Jaipur, is a public charitable trust duly registered under the Rajasthan Public Trusts Act, 1959. The late Maharaja Mansinghji, the ex-ruler of the erstwhile State of Jaipur, created a trust on April 16, 1959, by a registered deed and founded a museum in a portion of the City Palace, Jaipur, for the benefit of the public. BY a supplementary deed of trust executed in 1972, some more properties were settled on trust. It has been treated and accepted as a trust for charitable purposes within the meaning of section 2(15)and had enjoyed the exemption from tax under section 11 of the Income-tax Act, 1961 (hereinafter to he referred to as "the Act"). The assessee later on contended that it is an "educational institution" within the meaning of section 10(22) of the Act. This contention was negatived and disallowed by the income-tax authorities. No appeals were filed by the assessee against those orders by which it was refused to be treated as an "educational institution" under section 10(22) of the Act. The assessee again raised the same disputes for the assessment years 1966-67, 1974-75, 1975-76 and 1976-77. The Income-tax Officer as well as the Appellate Assistant Commissioner, in their orders, took the same view that the assessee is not an "educational institution ". The assessee went up in appeal before the Income-tax Appellate Tribunal, Delhi Bench, New Delhi. It was contended before the Tribunal by the assessee that it is maintaining a museum and the museum is an" educational institution ". It is, therefore, not assessable to tax under the Act. The Tribunal, by its order dated September 20, 1979, allowed the appeal and held that the assessee (trust) is running and maintaining a museum and the museum is an "educational institution" within the meaning of section 10(22) and is, therefore, not liable to pay any tax under the Act. The Commissioner of Income-tax, Jaipur, felt aggrieved by the aforesaid order of the Tribunal and moved the Tribunal to make a reference to this court. It is thus that we have the reference before us.

3. Nobody has appeared on behalf of the assessee.

4. We have heard Mr. B. R. Arora, learned counsel for the Revenue.

5. It was argued by Mr. Arora that right from 1959 to 1966-67 and thereafter from 1968 to 1973-74, the museum managed and maintained by the assessee (trust) was not accepted and treated as an "educational institution ". Those orders by which the museum was not treated as" educational institution "were not challenged by the assessee in appeals. It was argued that the judgment, annexure" 1) ", passed by this court on March 13, 1972, related to the question whether the assessee was liable to pay tax under the Rajasthan Entertainment and Advertisement Tax Act, 1967. It was for that limited purpose that the judgment is relevant to show that the museum maintained by the assessee is used for the education of the people. This judgment is no more good law in view of the pronouncements made by their Lordships of the Supreme Court in Sole Trustee, Loka Shikshana Trust v. CIT [1975] 101 ITR 234 . It was further urged by him that section 10(22) of the Act covers the case of an "educational institution" existing solely for educational purposes. Reliance, in support of the contention, was based on the aforesaid authority of the Supreme Court. We have bestowed our thoughtful consideration to the submissions made by Mr. Arora.
