Limitation for section 143(2) notice cannot be lifted by incidental findings on return validity or assessment

A finding by the appellate authority that a return was valid does not, by itself, lift the statutory limitation for issuing notice under section 143(2) unless that finding was necessary to decide the appeal. Where the controversy before the authority was confined to the validity of the return and the curing of defects, any observation on assessment beyond that issue has no legal effect for limitation. A time-barred notice under section 143(2) cannot be validated by an incidental or extraneous finding, and an assessment made pursuant to such notice is also invalid.

Issues: Whether the finding recorded by the appellate authority that the return was valid could lift the bar of limitation for issuing notice under section 143(2) and validating the assessment made thereafter.

Analysis: The return filed within time was treated as valid by the appellate authority in the rectification proceedings, but the controversy before it was confined to the validity of that return and whether the defects had been cured. The question of assessment was not directly in issue before that authority. A finding which is not necessary for the disposal of the appeal and does not arise from the subject-matter of the appeal cannot enlarge the scope of the proceedings or operate to lift the statutory time-limit for issuing notice under section 143(2). Accordingly, any observation or direction touching assessment, if outside the issue actually decided, is of no consequence for limitation.

Conclusion: The notice under section 143(2) issued after expiry of the prescribed period was invalid, and the assessment made in pursuance of that notice was also invalid.

Ratio Decidendi: Only a finding that is necessary for the disposal of the appeal can have legal effect for collateral consequences such as lifting a limitation bar; an extraneous or incidental observation cannot validate a time-barred notice or assessment.
