M/s. K.B. Tea Product Pvt. Ltd. & Anr. vs. Commercial Tax Officer, Siliguri & Ors. (Civil Appeal No. 2297 of 2011, with connected Civil Appeal Nos. 2298-2305 of 2011)
Background
Under West Bengal's sales tax law, "blending of tea" was originally included within the legal definition of "manufacture," which entitled small-scale industrial units engaged in tea blending to a tax holiday (exemption from sales tax on their manufactured goods) under a 1999 State incentive scheme. Relying on this, the appellants set up small-scale tea-blending units and obtained eligibility certificates for a seven-year exemption period. After enjoying the exemption for about two years, the State amended the law in 2001 to remove "blending of tea" from the definition of "manufacture," which caused the tax authorities to stop the exemption and modify the appellants' eligibility certificates. The appellants' challenge before the Tax Tribunal and the Calcutta High Court both failed, leading to this appeal.
Decision Breakdown
Justice M.R. Shah held that there can be no promissory estoppel against a statute, that what the appellants held was only an "existing right" (not a permanently "vested right"), and that once the legislature validly amended the definition of "manufacture" to exclude tea blending, the exemption ceased prospectively from the date of amendment, meaning the appellants were correctly denied the exemption from 01.08.2001 onward, and he dismissed all the appeals. Justice Krishna Murari took a different view, holding that the State's earlier tax-holiday scheme had created a genuine "legitimate expectation" in the appellants' favour, who had invested real money in reliance on the government's assurance; he held that where a legitimate expectation is withdrawn by a policy change, the State must affirmatively demonstrate a public-interest justification for doing so, which the government had failed to do here (no reasons for the amendment or its impact on affected businesses were shown), and on that basis he would have allowed the appeals and directed that the original exemption benefit continue for its originally promised period.
Lesson Learnt
Even a validly enacted law change can be challenged by businesses that relied on a government-created tax incentive, using the doctrine of "legitimate expectation", but as this case shows, judges can genuinely differ on whether a "promise" embedded in tax law is an enforceable expectation or merely a right that the legislature is always free to modify; readers relying on this judgment for a definitive rule should confirm how (and by whom) this split of judicial opinion was eventually resolved.
