" 'Sale' means any transfer of property in goods for cash or deferred payment or other valuable consideration, including a transfer of property in goods involved in the execution of a con- tract, but does not include a mortgage, hypothecation, charge er pledge.
Explanation 1 …. A transfer of goods on hire-purchase or other instalment system of payment shall, notwithstanding that the seller retains a title to any goods as security for payment of the price, be deemed to be a sale."
The hire-purchase agreement entered into by the petitioneic company provided that after all the monthly instalments had been paid, "'the hiring shall come to an encl and the vehicle shall, at the option of the hirer, become his absolute property; but until such payments as aforesaid have been made, the veJii .. cle shall remain the property of the owners. The hirer shall'. also have the option of purchasing the vehicle at any time dur .. ing the currency of this agreement by paying in one lump sum the balance of all the hire hereinbefore mentioned and any other expenses incurred by the owners relating to the transac- tion." The question for determination was whether the agree- ment was a transaction of mere hiring or one of hire-purchase within the meaning of Explanation 1 to s. 2(g) of the Act. Held, that the language of Explanation 1 to s. 2(g) of the z96z
Act was wide enough to include a mere transfer of goods with- out the transfer of the title thereto, if such transfer took place Install>""' Supply in the course of an agreement of hire-purchase or any other (P.) Ltd.
instalment system of payment. v. As the-Att did not define the term 'hire-purchase', it had Union °1 India to be construed in its ordinary Common Law sense, i.e., that it partook of the nature of a c.ootract of bailment with an element of sale added to it.
Lee v. Buller, [1893] 2 Q. B. 318 and Helby v. Matthews, [1895] A. C. 471, referred to. The non obstante clause in Explanation 1 to s. 2(g) of the Act did not govern the main clause of the said Explanation and its sole purpose was to emphasise the categorical statement of the law contained therein. Since the agreement in the instant case contained not merely a contract of bailment simpliciter bu\ also an element of sale, the transaction had rightly been sub- jected to sales tax.
There could be no force in the contention that the Act in so far as it sought to extend the concept of sale to what in law was not a real _sale, was unconstitutional. Mithan Lal v. State of Delhi, [1959] S.C.R. 445, referred to. Nor was there any substance in the contention that the
extended definition of the word 'sale' in the Act infringed Art. 14 of the Constitution. !tis well settled that in matters of taxation there can be no question of res judicata.

Sinha c. J. CourL under Art.. 32 of the Constitution for a. writ 8> [19ti2] z96z or order i.n the nature of mandamus and/or prohibi- 1 tion and/or other suitable writ, order or direction to
nsla ment upp y h (P.) Ltd. the respondents not to evy, c arge or co ect any v. sales tax on transactions of what the petitioners Union of India characterised as hire-purchase agreements, a typical example of which is contained in Annexure 'A' to the
Sinha c. f. petition, to be hereinafter examined in detail. The first petitioner is a private limited company incorporated under the Companies Act, with its reg;is- tered office at Janpat,h, New Delhi. The second peti-
tioner is the Managing Director and shareholder of that company and is directly interested in the result of this application, because it is claimed that his rights and property are directly involved. The com-
pany has been carrying on in Delhi the business of financing the purchase of new as well as second-hand motor cars and other kinds of motor vehicles. The system adopted by the Company for financing a pur-
chase such as aforesaid is as follows. A person desiring to purchase a motor vehicle fixes a bargain with the owner and the petitioner Company would then ad- vance the necessary finance on the terms and condi-
tions appearing in a printed copy of the agreement, marked Annexure 'A' to the petition. According to that agreement, the Company charges the 'Hirer' 2.n initial deposit by way of premium as a consideration
for granting the lease of tho vehicle, which deposit becomes the absolute property of the Company; the premium charged as aforesaid is a substantial amount, being usually 25% of the price in respect of new
vehicles. The 'Hirer' undertakes to pay instalments and when all the instalments are paid, the vehicle becomes the property of the 'Hirer' at his option, on payment of rupee one to the Company, as a conside-
ration for the option; until all the stipulated instal- ments have been paid and the option exercised as aforesaid, the vehicle remains the property of the Company as owners. The 'Hirer' is delivered posse13.
sion of the vehicle and he remains responsible to the Company for damage or destruction or loss. The 'Hirer' has to pay interest at the rate of one per cent. per mensem on all sums overdue. Until the option of
2 S.C.R. purchase is exercised by the 'Hirer', he is at liberty to return the vehicle and to put an end to the Hiring lnstalm:;; supply Agreement, on certain terms. Thus, under the agree-
(P.J Ltd. ment, the 'Hirer' has the use of the vehicle, which is v. entrusted to him as the property of the Company, Union of India and it is open to the 'Hirer' to become the purchaser
of the vehicle as aforesaid, but he is not bound to Sinha c. J. do so. The hire-money received by the Company, it is contended, is not a part of the price of the goods sold and is thus not liable to be taxed as SiJ,le-
price. The Bengal Finance (Sales Tax) Act, 1941 (Bengal Act VI of 1941) was extended to the State of Delhi, which is now the Union Territory of Delhi. In pursuance of the provisions of that Act, the Sales
Tax authorities started demanding and levying Rales tax on all transactions of the nature aforesaid on the ground that the instalments paid by the hirers to the Company were sales-price and, therefore, liable to
Sales Tax. The Company challenged the right of the Sales Tax authorities to levy any such tax on the ground that the law was beyond the competence of the legislature. Ultimately, the Company moved the
Punjab High Court (Circuit Bench at Delhi) under Arts. 226 and 227 of the Constitution. In the Writ Petition, which was registered as Civil Writ Applica- tion No. 289-D of 1954, the Company prl}yed for a
writ in the nature of prohibition and/or mandamus restraining the respondent from realising or le".·· ing any sales tax under the provisions of the Bengal .\.,,t, extended to Delhi. There was also a prayer for a writ
of certiorari quashing certain orders passed by the Sales Tax authorities in 1953-54. The said application was heard by a Division Bench, which allowed the petition and issued a mandamus to the State to forbear from
enforcing its notice for the re.alisation of the Sales Tax. It was held by the High Court that the State Legislature had not the power to enlarge the meaning of the words "Sale of Goods" by going beyond the
meaning attached to it by the Sa.le of Goods Act. After the judgment aforesaid of the High Court of Punjab, it is further alleged, a settlement was arrived at between the companies carrying. on hire-purchase
[196.2) '96' business in Delhi and the Commissioner of Sales Tair, Installn-:;;; Supply who ~s~ued a circul~r, bei~g Circular No. 10 of 1956, (P.) Ltd. contammg the followmg decisions of tho Department:–
"(i) Companies which are exclusively engaged iin Union of India the hire purchase business will not be treated as dealers and their certificate of registration will he Sinha c. J.
cancelled. (ii) Companies which are partially engaged in the business of hire purchase will continue to he dealers as hithertofore and their hire purchase transactions will be appropriately examined in the light of the
judgment of the Punjab High Court, and will be liable to Sales Tax at one stage. (iii) As a result of (i) above, sales made to the above Companies by the dealers in vehicles would
be liable to Sales Tax at the hands of the latter. (iv) In respect of vehicles, and machineries, etc., for which tax has been paid, at the time of pur- chases thereon from the market, no Sales Tax would
be payable in respect of hire monies collected on them by the hire purchase companies or on their re-sale or re-hire following repossession or on the exercise of the option of purchases by the hirer.
(v) In respect of second hand vehicles purchased by the companies from private individuals for pur- poses of hire purchase, the companies will not be liable to any sales tax either at the time of purchase
or in respect of subsequent transaction thereon. The Companies will be as other non-registered dealers, in view of (i), their Registration Certificates in res- pect of Hire purchase business having been can-
celled. (vi) The assessment which are already made will not be re-opened except in the case of M/s. Instal- ment Supply Co. Ltd. for which there are specified orders of the High Court.
(vii) In their up-to-date assessment., the hire pur- chase Companies should take upon themselves the responsibility to pay tax which they have save by making tax free purchases either from dealers or
from non-registered dealers. The assessment wiH, however, be made accordingly as before in the nor- mal way." Thereafter in the case of Mithan Lal v. State of Delhi(') 196' this Court examined the vires of the Beng.al Finance Instalm-;;:; Suftly (Sales Tax) Act, 1941, as extended to Delhi, and came
(P.) Ltd. to the conclusion that the law had been validly pro- v. mulgated. According to that decision, the definition Union oj India of 'sale' could be legally extended so as to make it
permissible to tax sale of goods involving the supply Sinha c. J · of materials in pursuance of building contracts. As a result of the decision aforesaid of this Court, a press note was issued by the Commissioner of Sales Tax,
Delhi, to the effect that provision regarding levy of tax on hire-purchase transactions was valid and that all hire-purchase dealers as come within the purview of ss. 4 and 7 of the Bengal Finance (Sales Tax)
Act, 1941, as extended to Delhi, are liable to pay sales tax and to get themselves registered under the Act; that all such hire-purchase dealers as were formerly registered with the Sales Tax Department
shall be deemed to be registered with effect from the first of April, 1958 for the purpose of the Act and that all hire-purchase dealers who had not got themselves registered so far should immediate-
ly have themselves so registered in order to avoid being penalised for contravention, of the provisions of the Act. In pursuance of the aforesaid circular of the Department, the petitioner company was also called
upon to comply with the requirements of the Act. The Company made representation to the Commis- sioner of Sales Tax that the Company and other such companies which deal in hire-purchase were not liable
to pay sales tax, but the Commissioner of Sales Tax refused to accept the Company's contention and answered to the following effect:- "l. The incidence of Sales Tax on such tran- actions is to be governed by the provisions of Sec-
tions 3 and 4 of the Central Sales Tax Act, 1956. If however, the vehicles are purchased by a Com- pany having its place of business in Delhi from a dealer outside Delhi on payment of Sales Tax of
that State and the vehicle is hire-purchased to the party in that very State, neither Delhi Sales Tax (I) (1959] S.C.R. 4'5· InsltJhnent Supply (P.) Ltd. v .. U11io11 o.f India Sinha C. /.
[1962] nor Central Sales Tax will be leviable on the Delhi firm irrespeci.ive of the fact that the Hire-purchase Agreement is enterer\ into at Delhi. If, however, vehicle is purchased in State 'A' but
is hire-purchased to a party in State 'B', Central Sales Tax will be leviable in the State according to the rules in force in that State. 2. The hire-purchase tra.nsactions of secondhand
vehicles, where the owner approaches the Hire Pur- chase Co. for finances against the vehicles, will be leviahle to Sales Tax, because according to the Hire. purchase Agreement the property in the vehicle
vests in the Hire Purchase Co. and this property is to be transferred to the so-called owner by virtue of the Hire-purchase transactions. Secondhand vehicles purchased outside Delhi and
hire-purchased to the parties outside Delhi or hire- purchase transactions conducted outside Delhi in which owner approaches the Hire-purchase Co. for finance will be governed by the clarification given
in 1 above. 3. In the case of vohicles purchased by the Hire. purchase Companies from the local registered deal- ers, they will not be required to pay any Sales Tax because all Hire-purchase companies will be regis-
tered and will be entitled to make tax free pur- chases of such vehicles. It is, therefore, rPgretted that it is not possible to accede to the request ma.do in this behalf. 4. Sales Tax will be payable on total amounts
charged by the Hire-purchase Co. from the hirer an<l it is not possible to waive Sales '.!.'ax on the so- callod incidental charges. 5. It is regretted that it is not possible to alter
the date of liability of the Hire-purchase Co. which has already been fixed with effect from 1st of April, 1958, in pursuance of the Snpreme Court Judgment. It is true that the Press Note was
issued in the month of June and so Hire-purchase Companies have been making purchases of vehicles on payment of sales tax. The Hire-purchase com- panies are advised to approach the dealers for
2 S.C.R. refund of the Sales Tax paid by them on such '96' purchases. p Instalment supply If, however, it is not possible for any Hire ur- (P.) Ltd. chase Co. to obtain refund of the SaleR Tax so paid
v. by them, the amounts so paid may be adjusted Union of India towards their liability on the hire purchase tran- sactions." Sinha c. J. On receipt of the answer of the Department, as
set out in the previous paragraphs, the petitioners moved this Court under Art. 32 of the Constitution on the ground that the "threatened action of the res- pondents is illegal and unconstitutional as the peti-
tioner company is not liable to pay sales tax on the transactions" described above. In support of the petition, the learned counsel for the petitioners has raised the following contentions:
(1) that the transactions in respect of which the peti. tioners are sought to be taxed are not covered by the explanation to s. 2(g) of the Bengal Finance (Sales Tax) Act, as extended to Delhi; (2) a.lternatively,
that is to say, if it is held that the explanation covers the transactions of the nature aforesaid, then the explanation, extending the concept of 'sale' is uncon- stitutional; (3) That in any case it is unconstitu-
tional as it infringes Art. 14 of the Constitntion in so far as the State of Delhi has been selected for hostile discrimination; ( 4) that the judgment of the Punjab High Court in Instalment Supply Ltd., New
Delhi v. State of Delhi(') is final and conclusive as between the parties to that judgment; (5) that if it is held that the judgment of the Punjab High Court, referred to above, has been superseded by the judg-
ment of this Court in M ithan Lal' s case ('), that judgment cannot be given retrospective operation; and (6) lastly, that the settlement between the Depart- ment and the Companies transacting business in
"Hire-purchase" is binding until the decision of this Court in Mithan Lal's case('), aforesaid. We shall exa- mine these arguments in the order in which they have been stated. The most important question in this case is: What
(1) A.I.R. 1956 Punj. 177. (2) (1959) s.c.R. 445. [1962] r96x is the true nature and character of the transaction I I –1 5 ppl which is the subject matter of the present contro· ns a men
u y h d (I'.) Ltd, versy? o t e terms an cond1t10ns of the agree- v. ment typified by Annexure 'A' to the petition, as. des. Union of India cribed above, constitute a mere agreement of hiring, as contended on behalf of the petitioners, or do they
8 ;n1ia c. f. constitute a contract of hire. purchase, within the meaning of explanation (1) t0 the definition of 'sale' contained in the statute in question, as contended on behalf of the respondents? There is no doubt that
the concept of 'sale', as it appears from the following words of the definition, along with explanation (l), is rather extended. In the definition of the term 'sale' for the purposes of the Act, the words are as
follows:- " 'Sale' means any transfer of property in goods for cash or deferred payment or other valuable consideration, including a transfer of property in goods involved in the execution of a contract, but
does not include a mortgage, hypothecation, charge or pledge. Explanation l.-A transfer of goods on hire-pur- chase or other instalment system of payment shall, notwithstanding that the seller retains a title to
any goods as security for payment of the price, be deemed to be a sale." It is clear from the definition that it includes not only what may be compendiously described as a sale under
the Sale of Goods Act, but also transactions, which, strictly speaking, are not sales, not even 'contracts of sale' but only contain an element of sale, that is the option to purchase, and that is the reason why the
explanation ends with the words "be deemed to be a sale", thereby indicating that a legal fiction has been introduced into the concept of 'sale' as ordinarily understood. The explanation has included within its
amplitude a mere transfer of goods without the trans- fer of title to the goods, if it is in the course of an agreement of the nature of "hire-purchase", or other t instalment system of payment. A contract of hiring,
under the Common Law, is one of the species of a contract of bailment and has, during the last 60-70 years, undergone a series of refinements as a result of r96r modern industrial and commercial developments. The
h. h , h b d fi d . h A Instalment Supply term ' ire-pure ase as not een e ne mt c ct. (P.) Ltd We have, therefore, to construe the expression in its v. ordinary Common Law sense, which may best be Union of India e![pressed iu terms of the Dictionary of Englis1 Law
by Earl Jowitt at pages 913-914, which runs as Sinha c. J. follows: "Hire-purchase-a system whereby the owner of goods lets them on hire for periodic payments by the hirer upon an agreement that when a certain
number of payments have been completed, the absolute property in the goods will pass to the hirer, but so that the hirer may return the goods at any time without any obligation to pay any balance of
rent accruing after return; until the conditions have been fulfilled, the property remains in the owner. The instrument by which the hire-purchase is effect- ed does not ordinarily require registration as a bill
of sale (Exp. Crawcour ( 1878) 9 Ch. D. 411J); the hirer is 'reputed owner' within the Bankruptcy Act, 1914 (H:xp. Brooks (1883) 23 Ch. D. 261); but the hirer does not 'agree to buy' within the Factors Act
or the Sale of Goods Act, 1893, so as to be able to sell or pledge the goods as if he were a mercantile agent (Helby v. Matthews (1895) A. C. 471; Brooks v. Biernstein (1909) 1 K.B. 98). Such agreements
are to be distinguished from agreements such as in Lee v. Butler (1893) 2 Q.B. 318, which are in fact a sale, the price being paid in instalments with the condition that the property passes when all the
instalments have been paid; here there is a binding agreement for the party to purchase, where in a true hire-purchase agreement there is not." In Halsbury's Laws of England, Third Edition,
Volume 19, paragraph 823, at pages 510-511, the nature of a hire-purchase transaction is thus expressed: "The contract of hire purchase is one of the varia- tions of the contract of bailment, but it is a modern
development of commercial life, and the rules with regard to bailments, which were laid down before Jnstatment Supply (P.) Ltd, v. Union of India Sinha C. } . [1962) any contract of hire purchase was contemplated,
cannot be applied simpliciter, because such a con- tract has in it not only the element of bailment but also the element of sale. At common law the term 'hire purchase' properly applies only to contracts of
hire conferring an option to purchase, but it is often used to describe contracts which are in reality agree- ments to purchase chattels by instalments, subject to a condition that the property in them is not to
pass until all instalments have been paid. The distinction between these two types of hire purclia.se contracts is, however, a most important one, because under the latter type of contract there is a binding
obligation on the hirer to buy and the hirer can therefore pass a good title to a purchaser or pledgee dealing with him in good faith and without notice of the rights of the true owner, whereas in the case
of a contract which merely confers an option to purchase there is no binding obligation on the hirer to buy, and a purchaser or pledgee can obtain no better title than the hirer had, except in the case of
a sale in market overt, the contract not being an agreement to buy within· the Factors Act, 1889, or the Sale of Goods Act, 1893." The .observations quot!'ld above are based mo.stly
on two leading cases which have come to be regarded as the locus classicus upon the subject, namely, Lee v. Butler (1) in which the transaction was described by Lord Esher, M.R., as "Hire and Purchase Agreements"
and Helby v. Matthews(') in which the House of Lords distinguished the former case on the ground that in that case there was a binding contract to buy and not merely an option to buy, without any obligation to
buy. Both these cases were decided in terms of Factors Act of 1889 (52 & 53 Viet. c. 45, s. 9). Both the kinds of agreements exemplified by the two lead- ing cases aforesaid would now be included in the
definition of 'hire-purchase' as contained in s. 21 of the Hire Purchase Act, 1938 (1 & 2 Geo .. 6, c. 53):- " 'Hire-purchase agreement' means an agreement for the bailment of goods under which the bailee
lI) (1893] 2 Q.B. 318, (2) [1•95] A.C. 471. may buy the goods or under which the property in r96r the goods will or may pass to the bailee, and where r 1 – b nsta me~it upp y y virtue of two or more agreements, none of which
(P.J Ltd. by itself constitutes a hire-purchase agreement, v. there is a bailment of goods and either the bailee Union of India may buy the goods, or the property therein will or may pass to the bailee, the agreements shall be
Sinha c. f. treated for the purposes of this Act as a single agreement made at the time when the last of the agreements was made." It is clear that under the Law, as it now stands,
which has now been crystallised into the section of the Hire Purchase Act, quoted above, the transaction partakes of the nature of a contract or bailment with an element of sale, as aforesaid, added to it. In such
an agreement, the hirer may not be bound to purchase the thing hired; he may or may not be. But in either case, if Lhere is an obligation to buy, or an option to buy, the goods delivered to the hirer by the owner on
the terms that the hirer, on payment of a premium as also of a number of instalments, shall enjoy the use of the goods, which ultimately may become his property, the transaction amounts to one of hire-purchase, even
though the title to the goods has remained with the owner and shall not pass to the hirer until a certain event has happened, namely, that all the stipulated instalments have been paid, or that the hirer has
exercised his option to finalise the purchase on pay- ment of a sum, nominal or otherwise. But it has been contended on behalf of the peti- tioners that there is no binding agreement to purchase
the goods and that title is retained by the owner not as a security for payment of the price but absolutely. According to third term of the agreement, on the hirer duly performing and observing the terms of the agree-
ment, with particular reference to the payment of the monthly instalments, "the hiring shall come to an end and the vehicle shall, at the option of the hirer, become his absolute property; but until such pay-
ments as aforesaid have been made, the vehicle aha.II remain the property of the owners. The hirer shalt also have the option of purchasing the vehicle at any [1962) Tij6I time during the currency of this AgreemPnt,, by paying
Instalment supply in one lump sum the balance of all the hire herein- (?.) Ltd. before mentioned and any other Bxpenses incurred by v. the owners relating to the tramaction." Union of India
It is clear, therefore, that in addition to the con. Sinha c. 1. tract of hiring an option has been given to the hirer to purchase or not to purchase. The more serious ques- tion on this part of the petitioners' contention is whe.
ther the non obstante clause in the explanation "notwithstanding that the seller retains a title to any goods as security for payment of the price" governs the main clause of the explanation. In our opinion,
it does not. The non obstante clause has been added only to emphasise the categorical statement of the law contained in the main clause to the effect that a transfer of goods on hire. purchase, etc., shall be deem-
ed to be a 'sale' even though there may be a stipula- tion to the effect that in spite of the transfer of goods to the hirer, the owner retains title to those goods until the happening of the ultimate event, namely,
completion of title at the opt.ion of the hirer. There is, thus, no doubt that the agreement in ques- tion does contain not only a contract of bailment simpliciter but also an element of sale, which element
has been seized upon by the legislature for the purpose of subjecting a transaction like that to the Sales Tax. This leads us to the second ground of attack raised by the petitioners, namely, that thu explanation, if it
has the effect of extending the concept of 'sale' to what, in law, is not a real sale, but only an incipient or inchoate sale, then in so far as the law has extend- ed the definition of 'sale' it is unconstitutional. This
contention has lost all its force, if ever it had any, in view of the decision of this Court in M ithan Lal's case('). But then it is argued that Mithan Lal's case(') re- quires re-consideration and that, in any view of the
matter, this Court did not consider the further attack based on Art. 14 of the Constitution. It is true that in Mithan Lal's case(') the contention that the enactment in question had infringed Art. 14 of the
(t) [1959] S.C.R. 445· Const.itution had not been raised. This Court, there- fore, had no occasion to pronounce on that aspect Instalm;,,; supply of the controversy We have, therefore, to con-
1P.) Ltd. sider the contention under head (3), namely, that though the Parliament may have had the power Union °! India to tax something which was not strictly speaking h k h . d'
Sinha C. ]. a 'sale', the law is open to t e attac t at 1t 1s- criminates against traders in Delhi inasmuch as, it is further contended, such a law has not been made applicable to the whole of India. In our opinion,
there is no substance in this contention because no proper found a ti on was laid in the plead in gs for sup- porting such a contention. It has not been averred that other Parp 'C' States lrnve not been similarly
treated. On the other hand, it does appear that under the Central Sales Tax Act (LXXIV of 1956), the defi- nition of 'Sale' contains the extended definition, without the non obstante clause, discussed above. Sec-
tion 2(g) of the Central Sales Tax Act, 1956, has the following definition: "'Sale' with its grammatical variations and cog- nate expressions, means any transfer of property in goods by one person to another for cash or for de-
ferred payment or for any other valuable considera- tion, and includes a transfer of goods on the hire purchase or other system of payment by instal- ments, but does not include a mortgage or hypothe-
cation of or a charge or pledge on goods." It would, thus appear'that hire-purchase transactions have been included within the definition of 'sale' for the purpose of Central Sales Tax, and this definition
has become applicable throughout India, and it can- not, therefore, be said that the State of Delhi, and now the Union Territory of Delhi, has been selected for hostile discrimination.
In our opinion, therefore, there is no substance in the contention that the ex- tendec'. definition of 'sale' in the main statute infringes Art. 14 of the Constitution. Now, the remaining contentions raised on behalf of
the petitioners may be disposed of by observing that what the Sales Tax Department does, or does not do, cannot change t.he law. The Department issued its [1962] '96' instructions to the Sales Tax Officers, in conformity
Instalm;;,i··s,,pply with the law as laid down in the judgment of the (P.J Ltd. Punjab High Court in Instalment Supply Ltd., New v. Delhi v. State of Delhi('). This Court later laid down
Union °! India the law more authoritatively in Mithan Lal's case(') and t.hc Deprutment was bound to take notice of what Sinha C. j. this Court had laid down. It cannot, therefore, be
argued that the Department had, in any sense estop- pcd itself by issuing t-hose instructions, or that this Court, by laying down the law in MithanLal's case(') had laid down a new rule of law which has no appli-
cation to pending proceedings for levy, assessment and realisation of sales tax, either in Delhi or elsewhere. There is another answer to the point of res judicata raised on behalf of the petitioners, relying upon the
decision of the Punjab High Court in Instalment Sup- ply Ltd., Nlw Delhi v. State of Delhi('). lt. is well settled that in matt.ors of taxation there is no question of res judicata because each year's assessment is final
only for that year and does not govern later years, because it determines only the tax for a particular 'period. (See the decision in the House of Lords in Society of ~Medical Officers of Health v. Hope (Valuation
Officer)(') approving and following the decision of the Privy Council in Broken Hill Proprietary Company Lirnited v . .M·anicipal Council of Broken Hill {4). As all the conlc,ntions raised on behalf of \.he peti-
tioners fail, this petition is dismissed with coats. (I) A I.Ii. 1956 Po:nj 177. (JI [1960] A.C. 551. Petition diS?nis.scd. (2) [1959] S.C. R. 4·•5· (4) [19>5] A.C. 94·
