U.L. Bhat, C.J.:- The following questions have been referred by Income-tax Appellate Tribunal under section 256(1) of the Income-tax Act, 1961 (for short "the Act"), at the instance of the Revenue : " 1. Whether on the facts and in the circumstances of the case, and on the proper construction of Entry 1 in the relevant part of the table appended to paragraph 20 of the Sixth Schedule of the Constitution, the Tribunal was justified in holding the income of the assesses arising from the cantonment area of Shilong town is exempt u/s. 10(26) of Income-tax Act, 1961 merely by reason of the sources of income being located in the Khasi and Hills District in spite of the fact that the sources of income of the assesses were at the cantonment area of Shillong ? 2. Whether item 1 of the relevant part appended to paragraph 20 of the Sixth Schedule to the Constitution has not to be read and understood having regard and to the provisions contained in sub-paragraphs (1) and (2) of paragraph 20 of the Sixth Schedule to the Constitution for purpose of determining the scope and affect of section 10(26) of the Income-tax Act, 1961 and whether the Tribunal did not err in law in reading and applying the said Table in isolation, without having regard to the provisions of sub-paragraphs (1) decision of the Tribunal is, therefore, not sustainable in law." 2. The assesses is a member of a Scheduled Tribe as defined in Clause (25) of Article 366 of the Constitution. She is working as principal of a Government College which is situated in the cantonment area, which is not a part of the tribal area. Her residence is within the tribal area of Meghalaya State. The capital of the State of Meghalaya is in Shillong town. The Income-tax Officer assessed her overruling her contention that there is no liability for income-tax. In appeal, the Appellate Assistant Commissioner (A. A. C.) held that her income is entitled to be exempted under Section 10(26) of the Act. In appeal, at the instance of the Revenue, this order was confirmed. Hence this reference. 3. Section 10 of the Act deals with income which is not included in total income. In appeal, the Appellate Assistant Commissioner (A. A. C.) held that her income is entitled to be exempted under Section 10(26) of the Act. In appeal, at the instance of the Revenue, this order was confirmed. Hence this reference. 3. Section 10 of the Act deals with income which is not included in total income. Sub-section (26) reads thus : "(26) in the case of a member of a Scheduled Tribe as defined in clause (25) of Article 366 of the Constitution, residing in any area specified in part I or part II of the Table appended to paragraph 20 of the Sixth Schedule to the constitution or in the States of Nagaland, Manipur and Tripura or in the Union territories of Arunachal Pradesh and Mizoram or in the areas covered by notification No. TAD/R/35/50/109, dated the 23rd February, 1951, issued by the Governor of Assam under the proviso to sub-paragraph (3) of the said paragraph 20 (as it stood immediately before the commencement of the North-Eastern Areas (Reorganization) Act, 1971(18 of 1971) any income which accrues or arises to him- (a) from any source in the areas, States or Union territories aforesaid, or (b) by way of dividend or interest on securities;" Arunachal Pradesh and Mizoram are now States. In order that income derived by the assesses is not to be reckoned for the purpose of the Act, three conditions must be satisfied, namely, (1) the assesses must be a member of a Scheduled Tribe, as defined in Article 366(25) of the Constitution, (2) the assesses must reside in any area specified in part I or part n of the Table appended to paragraph 20 of the Sixth Schedule or in the States of Nagaland or other States referred to therein, and, (3) the income must have accrued or arisen from any source in the areas, States or Union territories aforesaid, or by way of dividend or interest on securities. There is no controversy that the first condition is satisfied. The dispute is about the two latter conditions. 4. The person claiming exemption must be residing in any area specified in Part I or Part II of the Table appended to paragraph 20 of the Sixth Schedule to the Constitution. We are not concerned with the other areas specified in the provision for the purpose of this case, paragraph 20 of the Sixth Schedule defines tribal areas. 4. The person claiming exemption must be residing in any area specified in Part I or Part II of the Table appended to paragraph 20 of the Sixth Schedule to the Constitution. We are not concerned with the other areas specified in the provision for the purpose of this case, paragraph 20 of the Sixth Schedule defines tribal areas. Paragraph 20 reads as follows: "20 Tribal areas:-(1) The areas specified in Parts I, II and in of the Table below shall respectively be the tribal areas within the State of Assam, the State of Meghalaya and the Union territory of Mizoram. (2) Any reference in the table below to any district shall be construed as a reference to the territories comprised within the autonomous district of that name existing immediately before the day appointed under clause (b) of section 2 of the North-Eastern Areas (Reorganisation) Act, 1971 : Provided that for the purposes of clauses (e) and (f) of sub-paragraph (1) of paragraph 3, paragraph 4, paragraph 5, paragraph 6, sub paragraph(2) clauses (a), (b) and (d) of sub-paragraph (3) and sub-paragraph (4) of paragraph 8 and clause (d) of sub-paragraph (2) of paragraph 10 of this Schedue, no part of the area comprised within the municipality of Shillong shall be deemed to be within the Khasi Hills District." 5. An examination of paragraph 20 of the Sixth Schedule shows that the description of tribal areas has three facets, the first is a description in sub-para (1) stating that the areas specified in Part II of the table shall be the tribal areas within the State of Meghalaya. The second facet is the description in sub- para (2) that the reference in the table to any district shall be construed as a reference to the territories comprised within the autonoumous district of that name existing imme­diately before the day appointed under clause (b) of Section 2 of the North-Eastern Areas (Reorganisation) Act, 1971 (for short" the 1971 Act"). The third facet is one contained in the proviso to the effect that for the purposes of some other paragraphs and sub-paragraphs of Schedule Sixth, no part of the area comprised within the municipality of Shillong shall be deemed to be within the Khasi Hills District. The third facet is one contained in the proviso to the effect that for the purposes of some other paragraphs and sub-paragraphs of Schedule Sixth, no part of the area comprised within the municipality of Shillong shall be deemed to be within the Khasi Hills District. The proviso is relevant only for the purpose of some of these and other provisions of the Sixth Schedule and has no relevance in the application of any other provisions of the Indian Income Tax Act, 1961. 6. We have to find what is an area specified in part II of the Table in paragraph 20 of the Sixth Schedule. The area shown is Khasi Hills District. Khasi Hills District was earlier part of the United Khasi and Jaintia Hills District and after the formation of the Meghalaya State, it is an independent District and includes the areas within the Shillong cantonment and the tribal and normal areas of Shillong municipality. Thus areas specified in Part II of the Table will includes the cantonment area and the tribal and normal areas of the Shillong municipality. 7. Sub-paragraph (2) of paragraph 20 states that any reference in the Table to any district shall be construed as a reference to the territories comprised within the autonomous district of that name existing immediately before the day under clause (b) of section 2 of the 1971 Act. The autonomous district of Meghalaya came into existence by virtue of the Assam Reorganisation (Meghalaya) Act, 1969, for short "the 1969 Act." The State of Meghalaya came into existence by virtue of the 1971 Act. The 1969 Act was in force till the coming into force of the 1971 Act. The territories comprised within the autonomous district of Meghalaya existing imme­diately before the day appointed under the 1971 Act are the territories included in the autonomous State of Meghalaya by the 1969 Act. According to section 3 of the 1969 Act the autonomous State of Meghalaya shall subject to the provisions of sub-section (2) comprise the area described in two clauses. The clause (1) takes in the United Khasi-Jaintia Hills District as described in sub-paragraph (2) of para­graph 20 of the Sixth Schedule to the Constitution, as it then stood, exclusive of the proviso thereto. The clause (1) takes in the United Khasi-Jaintia Hills District as described in sub-paragraph (2) of para­graph 20 of the Sixth Schedule to the Constitution, as it then stood, exclusive of the proviso thereto. Sub-paragraph (2) of paragraph 20, as it then stood, took in the United Khasi-Jaintia Hills District comprising the territories which before the commencement of the Constitution were known as the Khasi States and the Khasi and Jaintia Hills District, excluding any areas for the time being comprised within the cantonment and municipality of Shillong, but including so much of the area comprised within the municipality of Shillong as formed part of the Khasi State of Mylliem. It is therefore clear that the traditional tribal areas of the erstwhile United Khasi-Jaintia Hills district or the successor Khasi Hills district excluded the areas comprising the contonment and municipality of Shillong, other than the areas which formed part of the Khasi State of Mylliem. Thus, according to sub-paragraph (2) of paragraph 20, the reference in Part II of the table to Khasi Hills District shall be construed as reference to the area comprised in the Khasi Hills District excluding the areas comprised within the cantonment and municipality of Shillong, other than the area which formed part of the Khasi State of Mylliem. According to section 5 of the 1971 Act there shall be a new State of Meghalaya comprising of the territories of the autonomous State of Meghalaya and so much of the territories comprised within the cantonment and municipality of Shilong as did not form part of the autonomous State of Meghalaya. This means that the State of Meghalaya comprises of area included in the autonomous State of Meghalaya plus some more area, namely, the area comprised within the cantonment and municipality of Shillong which did not form part of the autonomous State of Meghalaya. In other words, while the area specified in Part n of the table includes the larger area (cantonment and municipality area), and narrower connotation is given by sub-paragraph (2) of paragraph 20 as it stood at the time of the 1969 Act. 8. In other words, while the area specified in Part n of the table includes the larger area (cantonment and municipality area), and narrower connotation is given by sub-paragraph (2) of paragraph 20 as it stood at the time of the 1969 Act. 8. The reference in Section 10(26) of the Act is to a member of the Scheduled Tribe "residing in any area specified in Part I or Part II of the Table appended to sixth Schedule." The reference is to the area specified in the Table and not to the areas specified in the Table as restricted by sub-paragraph (2) of paragraph 20. The reference in Section 10(26) of the Act is by incorporation, that is, incorporating the Table in the Act. What is incorporated in section 10(26) of the Act is the Table appended to paragraph 20 of the Sixth Schedule and not paragraph 20 or to sub-paragraph (2) of Sixth Schedule. Since section 10(26) refers only to the Table, for the' purpose of understanding what are the area in which a member of the Scheduled Tribe is required to reside in order to be eligible for the benefit of section 10(26) of the Act, only the areas are specified in the Table appended to paragraph 20 and not to any other provision of paragraph 20. See paras 9 and 10 of MIS Onkarlal Nandlal vs. State of Rajasthar.,AIR1986 SC 2146. Part H of the Table takes in Khasi Hills District in the State of Meghalaya which includes area within the Shillong municipality inclusive of tribal and normal areas. We have to go by the areas specified in Part n of the Table and not by the areas as restricted or explained in sub-paragraph (2) of paragraph 20. Thus, we hold that the area of residence contemplated in section 10(26) of the Act is the Khasi Hills District which includes areas of Shillong municipality and cantonment. The assesses resides within the Shillong municipality and satisfies the second condition contemplated in section 10(26) of the Act. 9. The third condition is that the income must have been accrued or arisen from any source in the areas States or Union territories aforesaid. The Government College where the assesses is working is within cantonment area. Her salary is paid by the State Government of Meghalaya whose capital is in Shillong town. 9. The third condition is that the income must have been accrued or arisen from any source in the areas States or Union territories aforesaid. The Government College where the assesses is working is within cantonment area. Her salary is paid by the State Government of Meghalaya whose capital is in Shillong town. In either view of the case, the income accrues from source in the areas specified in Part II of the Table appended to paragraph 20 of the Sixth Schedule. The third condition is also satisfied. It must, therefore, follow that the assesses is entitled to exemption under section 10(26) of the Act. 10. We, therefore, answer the questions in the affirmative, that is, in favour of the assessee and against the revenue. A copy of this judgment under the signature of the Registrar and the seal of the High Court shall be transmitted to the Income-tax Appellate Tribunal. In the circumstances, there will be no direction as to costs.
