Viswanatha Sastri	 Arun B. Saharaya and Sardar Bahadur	 for the appellant. V.P. Gopalan Nambiar	 Advocate General for the State Kerala and V.A. Seyid Muhammad	 for the respondent. The Judgment of the Court was delivered by Bachswat	 J. The short question in this appeal is whether the proposed acquisition of the electrical supply undertaking of the appellant by the State of Kerala in pursuance of the notice exhibit G	 dated November 20	 1959 is authorised by section 6 of the . The appellant is the holder of a license for the supply of electrical energy in Ernakulam and other places in Cochin. The license was originally granted to the managing agents of the appellant under the Cochin Electricity Regulation III of 1902 then in force in Cochin and subsequently assigned to the appellant with the permission of the Cochin Government. On the merger of Travancore Cochin with the Union of India	 the was made applicable by the Part B States Laws Act	 1951 (Act III of 1951) to the Travancore Cochin area	 and the Cochin Electricity Regulation stood repealed. The (Act 54 of 1948) was also made applicable to the Travancore Cochin area by the Part B States Laws Act	 1951. On March 31	 1957 the Kerala Electricity Board was constituted	 and by s.71 of Act 54 of 1948	 any right and option to purchase the undertaking of the licensee under the was transferred to and vested in the Board. Now	 the right or option to purchase the undertaking of a licensee under s.7(1) of the then in force was exercisable "on the expiration of such period	 not exceeding fifty years	 and of every such subsequent period	 not exceeding twenty years as shall be specified in this behalf in the license. " Sub section (4) of s.7 provided: "Not less than two years ' notice in writing of any election to purchase under this section shall be served upon the licensee by the local authority or the State Government	 as the case may be." Clause 15(a) of the license held by the appellant provides: "The option of purchase given by Section 7	 sub section (i) of the Regulation shall first be exercisable on the expiration of 25 years from the commencement of this license and on the expiration of every subsequent period of ten years during the continuance of this license." Section 7(1) of the corresponds to section 7(i) of the Regulation	 that is to say	 of the Cochin Electricity. Regulation. The date of the commencement of the license is December 3	 1935. The period of 25 years mentioned in el. 15(a) of the license expired on December 2	 1930. The last date for giving the two years notice of the election to purchase on	 the try of ' December 2	 1960 required under section 7(4) of the Indian e electricity Act	 1910 expired on December 2. 1958. On February 11	 1959	 the State Electricity Board served on the appellant a notice	 exhibit B	 of its election to purchase the undertaking of	 the appellant on the expiry of December 2	 1960	 but this notice was not being in accordance with section 7	(4) was of no legal effect. By the Indian Electricity (Amendment) Act	 1959 (Act 32 1959)	 s.6 now in force was substituted for the old s.7 of the 	 with effect from September 5	 1959. Section 6 of the now in force reads: "6. (1) Where a license has been granted to any person not being a local authority	 the State Electricity Board shall	 (a) in 'the case of a license granted ' before the commencement of the Indian Electricity (Amendment) Act	 1959	 on the expiration of each such period as is specified in the license; and (b) in the case of a. license granted on or after the commencement of the said Act	 on the expiration of such period not exceeding twenty years and of every such subsequent period	 not exceeding ten years	 as shall be specified in this behalf in the license; have the option of purchasing the undertaking and such opt:on shall be exercised by the State Electricity Board serving upon the license a notice in writing of not less than one year requiring the licensee to sell the undertaking to it at the expiry of the relevant period referred to in this sub section. (2) Where a State Electricity Board has not been constituted	 or if constituted	 does not elect to purchase the undertaking	 the State Government shall have the like option to be exercised in the like manner of purchasing the undertaking. (3)Where neither the State Electricity Board nor the Government elects to purchase the undertaking	 any authority constituted for an area within which the area of supply is included shall have the like option to be exercised in the like manner of purchasing the undertaking. (4) If the State Electricity Board intends to exercise the option of purchasing the undertaking under this it shall send an intimation in writing of such intention to the State Government at least eighteen months before the expiry of the relevant period referred to in subsection (1) and if no such intimation as aforesaid is receiv 190 ed by the State Government the State Electricity Board shall be deemed to have. elected not to purchase the undertaking.

(6) Where a notice exercising the option of purchasing the undertaking has been served upon the licensee under this sect:on	 the licensee shall deliver the undertaking to the State Electricity Board	 the State Government or the local authority	 as the case may be	 on the expiration of the relevant period referred to in sub section (1) pending the determination and payment of the purchase price. (7) Where an undertaking is purchased under this section	 the purchaser shall pay to the licensee the purchase price determined in accordance with the provisions of sub section (4) of section 7A." On October 24	 1959	 the State Electricity Board served upon the appellant a notice exhibit D	 of its election to purchase the undertaking on the expiry of December 2	 1960. On October 29	 1959	 the State Electricity Board served upon the appellant another notice	 exhibit E	 of its election. On November 20	 1959	 the State Government served upon the appellant a notice	 exhibit G	 of its election to purchase the undertaking on the expiry of December 2. 1960. On November 14	 1960	 the appellant filed a writ petition in the High Court of Kerala impleading the State of Kerala and the Kerala State Electricity Board and asking for the issue of appropriate writs and orders restraining them from taking any action pursuant to the notices. B	D	E and G. On December 20. 1961	 a learned single Judge of the High Court passed the following order : "In view of the representation made before me by both the learned Advocate General appearing for the State	 the I st respondent	 and Mr. Krishnaswami lIyengar	 learned counsel appearing for the Kerala State Electricity Board. the second respondent. that for the purpose of this writ petition. the notices issued by the Kerala State Electricity Board	 Exs. B. D and E can be ignored	 it follows that neither the 1st respondent nor the 2nd respondent has any jurisdiction or power to take any action on the basis Exs. B. D or E. In view of the fact that I am uphold 191 ing the action of the State Government	 who had issued the notice exhibit G	 it follows that the 1st respondent alone is entitled to take further action under the Act. in pursuance of the notice	 exhibit G	 issued and sent along with the covering letter	 exhibit F on 20 1 1 1959. It follows	 subject to what is stated about Exs. B	 D and E	 that the writ petition has to be dismissed. There will be no order as to costs. " The effect of this order was that the State Electricity Board waived and abandoned all its rights of purchase of the undertaking under the notices	 Exs. B	 D and E	 and neither the Kerala State Electricity Board nor the State of Kerala had any jurisdiction or power to take any action on the basis of those notices	 and save as aforesaid	 the writ petition was dismissed	 and it was held that State Government was entitled to take further action under its notice	 exhibit G. Aggrieved by this order	 the appellant filed an peal in the Kerala High Court impleading the State Government only as the party respondent. The State Electricity Board did not file any appeal from the order of the learned single Judge. By its judgment dated October 4	 1962	 a Division Bench of the High Court dismissed the appeal. In paragraph 15 of its judgment	 Bench observed: "In its petition the appellant asked for reliefs both against the State Government and the State Electricity Board. However	 in the course of the hearing of the petition	 the Board gave up its claims under Exts. B. D and E	 and only the claim of the State Government under Ext. G was canvassed. The petition was	 in effect	 allowed: against the Board. The Baord has not appealed and is not a party to the present appeal; and its notices may therefore be ignored except to the extent that they may affect the rights of the State Government. " The appellant now appeals to this Court under a certificate granted by the High Court under articles 133(1)(a) and 133(1)(c) of the Constitution. On half of the appellant	 Mr. Vishwanath Sastry contended that (1) as the two years ' notice in writing of. the election to purchase the undertaking on the expiry of December	 2	 1960 was not served on the appellant as required by the old section 7(4) of the . 1910. the appellant acquired a vested right to hold the license until the expiry of a further period of ten years.that is to say	 until December	 2	 1970. and this vested right was not taken away either expressly or by necessary implication by the new s.6 of the introduced by the amending Act 32 of 1958; (2) the expression "on the expiration of each such period as is specified in the license" in the new s.6(1)(a) means a period which has not expired and on the expiry of which the option may be legally exercised. and since in the absence of the two years ' notice required under the old s.7(4)	 the option of purchase on the expiry of December 2	 1960 could not be legally 192 exercised	 the new s.6(1) did not confer any option of purchase on the expiry of December 2	 1960 and the first option exercisable under the new s.6(1) would be on the expiry of December 2	 1970; (3) sub sections (4) and (5) of the new s.6 show that the period on the expiry of which the option under sub s(1)of s.6 is exercisable	 is a period which would expire at least 18 months after the coming into force of the new s.6	 that is to say	 after September 5	 1959	 and since the period expiring on December 2	 1960 is not such a period	 the new s.6(1) did not confer any option of purchase on the expiry of December 2	 1960; and (4) in any event	 the State Electricity Board having duly elected to purchase the undertaking on the expiry of December 2	 1960	 the State Government acquired no option of purchase under sub s(2) of s.7 of the . On behalf of the respondent. Mr. V.P. Gopalan Nambiar	 the Advocate General of Kerala	 contended (1) that the absence of two years ' notice under the old s.7(4) of the did not confer upon the appellant a vested right to hold the license until the expiry of December 2	 1970	 and the immunity from compulsory purchase under the old s.7 arising from the non service of the requisite two years ' notice could be	 and	 in fact	 was taken away by the new s.6	 which required only one year 's notice of intention to purchase the undertaking; (2) assuming that the appellant acquired under the old s.7 a vested right to hold .the license until December 2	 1970	 such vested right was taken away by the new s.6	 which expressly applies to licenses granted before its commencement	 and the period of 25 years is a period specified in as the license on the expiry of which the option of purchase was legally exercisable; (3) sub sections (4) and (5) of the new s.6 did not cut down the plain meaning of sub s(1) of the section and the option on the expiry of the period of 25 years was vested 'under sub s(1) of s.6	 though this period did not expire 18 months after September 5. 1959; and (4) as the State Electricity Board did not send to the State Government any intimation in 'writing 'of ' its intention to exercise the option on the expiry of December 2	 1960 as required by sub s(4) of s.6	 the Board must be deemed to have elected not to exercise this option	 and consequently by sub S(2) of s.6. the State Government is vested with the option We think that the fourth contention of Mr. Viswanatha Sastry is sound	 and should be accepted. Assuming	 without deciding	 that the option of purchasing the undertaking on the expiry of the period of 25 years specified in the license was available under sub s(1) of s.6	 such option vested in the State Electricity Board	 and as the Board duly elected to purchase the undertaking	 the State Government acquired no right or option of purchasing the undertaking under s.6. On this ground alone	 the appeal should be allowed	 and in this view of the matter	 we do not think it necessary to express any opinion on the other contentions urged 193 before us. As far as the State Electricity Board is concerned	. it has abandoned and waived its option of purchase on the expiry of 25 years. Sub section (1) of s.6 expressly vests in the State Electricity Board the option of purchase on the expiry of the relevant period specified in the license. But the State Government claims that under sub s(2) of s.6 it is now vested with the option. Now	 under sub s(2) of s.6	 the State Government would be vested with the option only "where a State Electricity Board has not been constituted	 or if constituted	 does not elect to purchase the undertaking. " It is common case that the State Electricity Board was duly constituted. But the State Government claims that the State Electricity Board did not elect to purchase the undertaking. For this purpose	 the State Government relies upon the deeming provisions of sub s(4) of s.6	 and contends that as the Board did not send to the State Government any intimation in writing of its intention to exercise the option as required by the sub section	 the Board must be deemed to have elected not to purchase the undertaking. Now	 the effect of sub s(4) read with sub s(2) of s.6 is that on failure of the Board to give the notice prescribed by sub s(4)	 the option vested in the Board under sub s(1) of s.6 was liable to be divested. Sub section (4) of s.6 imposed upon the Board the duty of giving after the coming into force of s.6 a notice in writing of its intention to exercise the option at least 18 months before the expiry of the relevant period. Section 6 came into force on September 5	 1959	 and the relevant period expired on December 3. 1960. In the circumstances	 the giving of the requisite notice of 18 months in respect of the option of purchase on the expiry of December 2	 1960	 was impossible from the very commencement of s.6. The performance of this impossible duty must be excused in accordance with the maxim	 lex non cogitate ad impossible (the law does not compel the doing of impossibilities)	 and sub s(4) of s.6 must be construed as not being applicable to a case where compliance with it is impossible. We must therefore	 hold that the State Electricity Board was not required to give the notice under sub s(4) of s.6 in respect of its option of purchase on the expiry of 25 years. It must follow that the Board cannot be deemed to have elected not to purchase the undertaking under sub s(4) of s.6. By the notice served upon the appellant	 the Board duly elected to purchase the undertaking on the expiry of 25 years. Consequently	 the State Government never became vested with the option of purchasing the undertaking under sub s(2) of s.6. The State Government must	 therefore	 be restrained from taking further action under its notice	 exhibit G	 dated November 20	 1959. In the result	 the appeal is allowed	 and the respondent State of Kerala is restrained from taking any action under the notice	 exhibit G	 dated November 20	 1959. The respondent shall pay to the appellant the costs in this Court. We direct the parties to pay and bear their own costs in the Courts below. Appeal allowed.

The appellant held a licence for the supply of electrical energy in Kerala which was granted for a period of 25 years	 and was subject to continuation for ten year terms in the absence of a notice by the local authority or State Government of an election to purchase the undertaking. The first 25 year term of the licence expired on December 2	 1960	 and prior to that	 on October 24 and again on October 29	 1959	 the State Electricity Board gave notice to the appellant under s.6(1) of the 	 to purchase the under taking on the expiry of the licence. On November 20	 1959	the State Government also served notice on the appellant of its election to purchase the undertaking on December 2	 1960. In November 1960	 the appellant filed a writ petition in the High Court seeking orders restraining the State Electricity Board and the respondent State Government from taking any action pursuant to the notices given by them. In the course of the hearing the petition the State Electricity Board waived and abandoned all its rights of purchase of the Undertaking. The writ petition thereafter dismissed and it was held that the State Government was entitled to take further steps under its notice dated November 20	 1959. An appeal against this decision to a Division Bench of the High Court was dismissed. In the appeal to the Supreme Court	 the appellant contended	inter alia	 that the State Electricity Board having duly elected under 6(1) to purchase the undertaking on the expiry. of the licence	 the State Government acquired no option of purchase under section 6(2) the 1910 Act. HELD: Any option of purchasing the undertaking on the expiry of the period of 25 years specified in the licence under section 6(1) vested in the State Electricity Board	 and as the Board duly elected to purchase the undertaking by the notice served on the appellants	 the State Government acquired no right or option of purchasing the undertaking under section 6. [193 G H] As section 6 came into force less than eighteen months before December 2	 1960	 it was impossible for the Board to have given notice to the State Government as required by section 6(4) of its intention to exercise the option. On the principle of lex non cogit ad impossibil must therefore ' be construed as not being applicable in the that the Board could not be deemed circumstances of the case	 so elected not to purchase the undertaking under section 6(4).[193 E F]
