Court denies sales tax exemption to company under Assam Acts; promissory estoppel not applicable

The court ruled against the appellant, a private limited company, in their claim for sales tax exemption under the Assam Industries (Sales Tax Concessions) Act, 1986 and subsequent 1987 Act. The court held that the company did not qualify as a new industrial unit under the Acts, emphasizing that the doctrine of promissory estoppel cannot override statutory provisions. The change in legislation rendered the appellant ineligible for exemptions under previous policies, and their failure to challenge the validity of the new Act further supported the denial of sales tax exemption. The court dismissed the writ appeal, with each party bearing their own costs.

Issues Involved:
1. Interpretation of industrial policies for sales tax exemption.
2. Application of the doctrine of promissory estoppel in government promises.
3. Validity of statutory provisions for sales tax concessions.
4. Repeal of the Assam Industries (Sales Tax Concessions) Act, 1986.
5. Entitlement to sales tax exemption under different industrial policies.
6. Applicability of legal principles in determining sales tax exemptions.
7. Judicial interpretation of statutory provisions for industrial units.

Interpretation of Industrial Policies for Sales Tax Exemption:
The case involved a private limited company established in 1961 under the small-scale sector, seeking incentives under the Industrial Policy of 1982 and its subsequent review in 1986. The company underwent expansion, modernization, and diversification, spending over eight lakhs for these activities. An eligibility certificate was issued, granting sales tax exemption from April 1, 1988, to March 31, 1993. However, the government refused sales tax exemption under the 1986 Act, stating that the company did not qualify as a new industrial unit under the Act.

Application of the Doctrine of Promissory Estoppel in Government Promises:
The appellant contended that the government's promise of sales tax concessions under the 1982 policy should be honored based on the doctrine of promissory estoppel. However, the court rejected this argument, emphasizing that estoppel cannot hinder the operation of law or bind promises contrary to statutes. The court held that the doctrine of estoppel cannot compel the government to fulfill promises conflicting with statutory provisions.

Validity of Statutory Provisions for Sales Tax Concessions:
The Assam Industries (Sales Tax Concessions) Act, 1986 was repealed by the 1987 Act, which defined new industrial units differently. The appellant's claim for sales tax exemption under the 1987 Act was rejected due to the company not meeting the criteria for a new industrial unit. The court upheld that the change in statutes rendered the appellant ineligible for sales tax exemption under the new provisions.

Repeal of the Assam Industries (Sales Tax Concessions) Act, 1986:
The 1986 Act was replaced by the 1987 Act, leading to changes in the criteria for sales tax exemptions for industrial units. The court emphasized that the doctrine of promissory estoppel cannot be invoked to enforce promises that conflict with the provisions of the new Act. The appellant's failure to challenge the vires of the 1987 Act further supported the denial of sales tax exemption.

Entitlement to Sales Tax Exemption Under Different Industrial Policies:
The appellant argued for sales tax exemption under the 1986 Act despite its repeal by the 1987 Act. However, the court held that the change in legislation rendered the appellant ineligible for exemptions under the previous policy. The court differentiated this case from precedents where notifications could not deny benefits available under the incentive policy itself.

Applicability of Legal Principles in Determining Sales Tax Exemptions:
The court emphasized that the doctrine of estoppel cannot confer powers on public authorities beyond legal limits or legitimize actions beyond statutory authority. The judgment highlighted that the appellant did not challenge the vires of the 1987 Act, making them ineligible for sales tax exemptions under the new statutory provisions.

Judicial Interpretation of Statutory Provisions for Industrial Units:
The court interpreted the provisions of the Assam Industries (Sales Tax Concessions) Act, 1987 to determine the eligibility of the appellant for sales tax exemptions. The court held that the appellant's industry did not qualify as a new industrial unit under the Act, thereby upholding the decision to deny sales tax exemption. The judgment dismissed the writ appeal as meritless, with each party bearing their own costs.
