Jurisdictional objection waiver: assessee's participation after notice bars later challenge, remedial reassessment permitted within timeframe.
The Supreme Court held that an assessee who participates in assessment proceedings after receiving an assessment-process notice without timely challenging the assessing officer's jurisdiction is barred from later disputing that jurisdiction under the statutory limitation. It set aside the High Court's order and directed the assessing officer to complete the assessment within a short prescribed timeframe, with the proviso that the assessee may not plead limitation in that completion process.
