Trust deed construction and indeterminate beneficiary shares triggered tax assessment under the proviso.

A trust deed must be construed on its own language, and not by importing tenancy in common under Dayabhaga law, where the instrument instead creates distinct maintenance and education benefits and directs surplus income to be accumulated for the trust fund. Because clause (1)(i) did not assign any equal or defined fraction of income to the immediate beneficiaries, their shares were indeterminate. The first proviso to section 41(1) of the Indian Income-tax Act, 1922 therefore applied, and assessment on that basis was upheld in favour of the Revenue.

Issues: (i) Whether the trust deed had to be construed on its own terms or by importing the idea of tenancy in common under Dayabhaga law. (ii) Whether the beneficiaries' shares under clause (1)(i) of the trust deed were determinate so as to exclude the first proviso to section 41(1) of the Indian Income-tax Act, 1922.

Issue (i): Whether the trust deed had to be construed on its own terms or by importing the idea of tenancy in common under Dayabhaga law.

Analysis: The governing question was the intention expressed in the deed itself. The general rule that interests created in favour of more than one person are ordinarily treated as tenancy in common was accepted only subject to the language of the instrument. The deed here did not express a tenancy in common or equal beneficial allotment; instead it created different forms of benefit for the immediate beneficiaries and directed any surplus to be accumulated as accretion to the trust fund for remote beneficiaries.

Conclusion: The deed had to be interpreted on its own terms and not by importing tenancy in common from Dayabhaga law.

Issue (ii): Whether the beneficiaries' shares under clause (1)(i) of the trust deed were determinate so as to exclude the first proviso to section 41(1) of the Indian Income-tax Act, 1922.

Analysis: Under clause (1)(i), one son was to be maintained and educated, while the other son and the two daughters were to be maintained. No equal or defined fraction of income was assigned to any of them, and the trustees were directed to accumulate any surplus as accretion to the trust fund. The absence of an express division of income, coupled with the differing nature of the benefits and the provision for accumulation, showed that the beneficiaries had only rights to maintenance or maintenance and education, not determinate shares in the income.

Conclusion: The beneficiaries' shares were indeterminate and the first proviso to section 41(1) of the Indian Income-tax Act, 1922 was applicable.

Final Conclusion: The reference was answered in favour of the Revenue, holding that the trust deed did not create determinate shares for the immediate beneficiaries and that assessment under the proviso was attracted.

Ratio Decidendi: In construing a trust deed, the beneficiaries' shares are determinable only from the instrument's own terms; where the deed grants only maintenance or maintenance and education rights and directs surplus income to be accumulated as accretion to the trust fund, the beneficiaries' shares are indeterminate for tax assessment purposes.
