SUPREME COURT REPORTS 
(1992) 3 S.C.R. 
The appellant-Company established its Aluminium Smelter Plant at 
Belgaum in the State of karnataka. On March 26, 1966 a tripartite agree-
ment was entered into between the Company, the Electricity Board and the 
State of Karnataka. A second tripartite agreement,, in supersession or the 
earlier one, was entered on August 7, 1976 between the parties providing 
for uninterrupted supply of power to the company at concessional rates. 
According to the appellant-company the agreement of 1976 was made in 
view of the industrial policy of the Government of llidia and the guidelines 
stated by the Government in the matter of electricity tariff to be applied 
to aluminium plants. In July 1980, the Electricity Board inc~ the 
power rate far beyond the prescribed rate in the agreement. Subsequently, 
C the State of Kamataka enacted the Electricity (Supply) (Karnataka 
Amendment) Act, 1981 amending Section 49 of the Electricity (Supply) Act 
1948. The amended Section 49 empowered the Electricity Board to increase 
its tariff rates notwithstanding any agreement with the consumers. On 
February 2, 1981 the Board further increased the tariff rate. Aggrieved byยท 
D increase of tariff rates and the consequential demands for payment of bills 
on the basis of increased tariff the company filed a writ petition challeng-
ing the vires of the Amending Act on the score of legislative competence 
and also on the ground of arbitrary action of revising the tariff without 
justification and the unjust classification of the aluminium Smelter Plant

in the category of other power tariff industries included in the category of 
HT IA Industries ignoring the special features of aluminium smelter plant. 
It was also contended that since the State Government invited the company 
to establish the plant by assuring uninterrupted supply of power at con-
cessional rates, the principle of promissory estoppel was applicable and 
consequently the demand of tariff contrary to agreement was. illegal and 
arbitrary. 
The High Court upheld the validity of the impugned legislation by 
holding that : (1) under the amended provisions of Section 49 of the 
Electricity (Supply) Act uniformity was the basis of tariff and since all the 
powe~ tariff industries were treated alike the treatment meted out to the 
G company was not discriminatory under Article 14; (2) the enhancement of 
tariff was not violative of Article 19(1) (g); (3) no special promise was held 
out by the State or Electricity Board to the C~m~ny that a particular 
formula will be applied in the case of coiisumption of electricity by the 
company; that the doctrine of promissory estoppel was not attracted in the 
H sphere of statutory power and since the impugned action was a conse-

quence of the amended provision of Section 49 the question of promissory A

estoppel did not arise; (4) the State Legislature was not denuded of its 
legislative competence merely because the Parliament declared aluminium 
industry as a controlled industry under the Industries (Development and 
Regulation) Act, 1951; and (5) the notification issued by the Central 
Government fixing the aluminium policy and also indicating the tariff B
