Scope of reassessment under section 34: tax authorities may include additional escaped income beyond the item prompting the notice.

When a notice under section 34 is issued on a particular item of escaped income, the court held that tax authorities may lawfully include other items of escaped income in reassessment. The court interpreted "definite information" as requiring more than suspicion but not exact quantification, "discovers" as the officer forming a belief on material before him, and "such income" as qualifying a class of escaped income rather than restricting reassessment to only the narrowly described item; the provision is procedural machinery to be construed to make reassessment workable.

Issues: Whether, when a notice under section 34 is issued based on a particular item of escaped income, the Income-tax authorities may include other items of escaped income in the reassessment in addition to the item that prompted the notice.

Analysis: The Court examined the meanings of the phrases "definite information", "discovers" and "such income, profits or gains" in section 34 as it stood for the relevant year. It relied on precedent and statutory context to conclude that "definite information" requires more than mere suspicion but need not identify exact quantity or quality of escapement; "discovers" means the officer comes to a conclusion or has reason to believe on the material before him; and the adjective "such" qualifies the class of income that has escaped assessment rather than limiting reassessment to only those specific items precisely described in the information. The Court further noted that section 34 is procedural machinery ancillary to the charging provisions and should be construed so as to make the machinery workable, not to unduly fetter tax authorities. Authorities and commentary relied on by the assessee were considered and distinguished on their facts, including that decisions restricting reassessment often addressed appellate powers rather than the Income-tax Officer's power to proceed under section 34.

Conclusion: The question is answered in the affirmative. In the circumstances when a section 34 notice is issued based on a certain item of escaped income, it is permissible for the Income-tax authorities to include other items of escaped income in the assessment in addition to the item which initiated the notice.
