Appeal No 1032 of 1968
GL Sanghi KK Jain Pramod Dayal AD Sangar and Bishambar  Lal for the Appellant
Gopal Subramanium and Mrs Shobha Dikshit for the Respond ents
The Judgment of the Court was delivered by THAKKAR J
The appellant invoked the extraordinary jurisdiction of the High Court under Article 226 of the Constitution of India in order to challenge the order passed by the respondent UP Electricity Board levying a sur charge of 55 paise per unit of electricity drawn by the appellant in excess of the permissible 70 per cent autho rised by the State Government
State Government had imposed a ban on drawing electricity in excess of 70 per cent of the consumption in exercise of powers under Section 22B of the of 1910 having regard to the fact that on account of short fall of rain the generation of electricity had been adversely affected and it was not possible to supply electricity to the consumers as per the demand
The learned Single Judge of the High Court dismissed the Writ Petition inter alia on the 333 ground that the equities were against the appellant writ petitioner in view of the fact that the respondent Board had purchased electricity from the Damodar Valley Corpora tion DVC at the rate of 457 per unit in order to make available the electricity as per the demand of the appellant and other industrial units at their request
Says the learned Single Judge It appears to me that there are no equities in favour of the petitioner and on this ground also the petitioner is not entitled to any relief
The petitioner factory and other industries had requested the State Government and the Board to augment supply of electrical energy by obtaining it from the Damodar Valley Corporation and other sources and has offered to pay additional expenses which the State Government or the Board might have to incur for it
In order to accommodate the petitioner factory and other industries the State Gov ernment and the Board did not exercise the power to disconnect their connections and obtained electrical energy from the Damodar Valley Corporation and had to pay certain sums of money therefore
They were certainly enti tled to recover those amounts from the peti tioner factory and other industries
It does not lie in the mouth of the petitioner now to say that the Board is not entitled to levy a surcharge for recovery of the amount which they have spent in obtaining extra electrical energy from the Damodar Valley Corporation
The Division Bench has confirmed the decision of the learned Single Judge
Two contentions have been urged in support of this appeal
The first contention is that the Electricity Board had no authority to charge 55 paise per unit in excess of the agreed rate without giving one month s notice as contem plated by the agreement
The second contention is that the levy of the surcharge resulted in a retrospective levy and therefore it was not in accordance with law
So for as the principal contention is concerned we are unable to accede to the submission that the Board had no legal authority to levy 55 paise surcharge in respect of the supply in excess of the 70 per cent authorised by the State Government
The agreement itself does not envision the supply of electricity in violation of the ban imposed by the State Government in exercise of the power under section 22 B of the 
Nor does the agreement stipulate the rate at which such supply should be charged if not withstanding the ban against the supply a consumer draws electricity in excess of the 334 permissible quantity
Thus the agreement is silent on this aspect
Therefore the Board was justified in invoking its power under section 493 of the Electricity Supply Act 1948 which authorises a Board to supply electricity by charging a different tariff having regard to the geographi cal position of the area the nature of the supply purpose for which the supply is required and any other relevant factors Section 49 3 of the Act is wide enough to cover a situation where electricity in excess of the authorised quantum is drawn in disregard of the ban imposed in view of the shortage of the supply position in the face of the ban imposed under Section 22 B of the as also to cover a situation where at the express request of the appellant as per the averment contained in the affidavit filed on behalf of the respondent electricity is purchased from some other authority in the present ease from DVC and is supplied to the consumers
We are therefore of the view that the electricity Board had the legal authority to levy and collect surcharge of 55 paise per unit from the appellant in regard to the supply in excess of the 70 per cent authorised in the context of section 22 B of the 
We are buttressed in this view by a decision of this Court in Adoni Cotton Mills etc
vs The Andhra Pradesh State Electricity Board  Ors 1977 1 SCR page 133
In Adoni Cotton Mills case the view has been taken that the power to enhance the tariff is included in section 49 of the 1948 Act and that section 493 authorises a Board to fix different tariffs for the supply of electricity having regard to the geographical position etc and any other relevant factors
The expression any other relevant factors  is not to be construed ejusdern generis and that the combined effect of Section 49 and the terms and conditions of supply is that having regard to the nature of supply and other relevant factors particularly when there is shortage of electricity the Board has the power to enhance the rates
If there is shortage of electricity there is to be restriction on supply and the Board can disconnect supply if the quota is exceed ed
The Board can also impose higher rates if the quota is exceeded
The imposition of higher rates is only to sanc tion the rigour of ration by making persons who exceed the quota liable to pay higher rates
 We are therefore of the opinion that so far as the first point is concerned the view taken by the High Court cannot be taken exception to
With regard to the retrospective effect argument the electricity was supplied from November 1966 till February 20 1967 on which date the notification imposing the levy was issued
It was therefore urged that so far as the period anterior to February 20 1967 is concerned the effect of the levy would be retrospective
The High Court has taken the view that it does not amount to making the tariff retrospective but the effect of the notification is to recover the surcharge in respect of the energy which was supplied in excess of the permissible quota
It was also urged on behalf of the re spondents that in so far as the period anterior to February 20 1967 was concerned the appellant was not entitled to make the recovery as it would amount to altering the tariff
This argument was advanced in the context of the stipulation in the agreement that 335 one month s notice would be given before increasing the tariff
Since we are of the view that the Board had the statutory authority to impose the surcharge in respect of the electricity supplied in excess of the permissible quota and having regard to the fact that the supply was made after obtaining it from the DVC at a higher rate and having further regard to the fact that the impost of the surcharge is construed as having been made under the statutory author ity the stipulation in the agreement does not come into play
Under the circumstances we do not see any good ground to disturb the findings recorded by the High Court
The appeal therefore fails and is dismissed
There will be no order as to costs
APJ Appeal dismissed
