Mandatory time limit for liability determination under sales tax law made late determination void and without jurisdiction.

Section 4-A of the M.P. General Sales Tax Act, 1958 required liability-determination proceedings to be completed within twelve months from institution, and the scheme of section 18(6)(a) and rule 52-A showed that this step had to precede assessment. On the stated facts, the proceedings commenced on 27 March 1985 but were concluded only on 3 November 1988, so the determination was made after expiry of the statutory period. The notice issued later merely reflected an already time-barred determination. The challenge to the second proviso to section 39(1) was not examined because it was unnecessary, and the impugned notice/order was quashed as without jurisdiction.

Issues: Whether the liability determination proceedings under section 4-A of the M.P. General Sales Tax Act, 1958 were completed within the prescribed twelve-month period and, if not, whether the resulting notice/order was without jurisdiction and liable to be quashed.

Analysis: Section 4-A required the Commissioner to complete the determination of liability within twelve months from the date of institution of the proceedings. The scheme of the provision, read with section 18(6)(a) and rule 52-A, showed that the liability determination had to be concluded first within the statutory time limit before the matter could move to assessment. On the facts, the proceedings began on 27 March 1985 and culminated only on 3 November 1988, well beyond the prescribed period. The notice issued thereafter merely communicated a determination already made after expiry of the statutory period. The challenge to the second proviso to section 39(1) was not examined because it was unnecessary for deciding the case.

Conclusion: The determination of liability was barred by limitation and therefore without jurisdiction; the impugned notice/order was quashed, and relief was granted to the petitioner.

Ratio Decidendi: Where a statute prescribes a mandatory time limit for completing liability-determination proceedings, any determination made after expiry of that period is void and unenforceable.
