Summarize the following court judgment. ivil Appeal No. 1935 of 1981. From the Judgment and Order dated 8.4. 1980 of the Calcutta High Court in Matter No. 143 of 1980. Sukumar Bhattacharya and G.S. Chaterjee for the Appellant. J. Ramamurthy. g. Rajappa and Ms. A. Subhashini for the Respondents. The Judgment of the Court was delivered by K.N. SINGH	 J. The appellant is a Government Corporation engaged in jute industry. It was assessed to income tax for the assessment year 1974 75 by the Income Tax Officer. The assessee preferred appeal before the Appellate Assistant Commissioner. During the hearing of the appeal	 the assessee raised an additional ground claiming deduction of Rs. 11	54	995 on the ground of liability of Purchase Tax. The assessee claimed that in view of the decision of this Court in Kedarnath Jute Company Limited vs Commissioner of Income Tax	 [19771 the aforesaid amount being tax liability should be deducted from its income for purposes of charging tax. The Appellate Assistant Commissioner permitted the assessee to raise the additional ground and after hear ing the Income Tax Officer	 he accepted the assessee 's claim and allowed deduction of Rs. 11	54	995 in computing the total income of the assessee for the assessment year 1974 75. The Revenue preferred appeal before the Income Tax Appellate Tribunal. The Tribunal held that the Appellate Assistant Commissioner had no jurisdiction to entertain an additional ground or to grant relief to the assessee on a ground which had not been raised before the Income Tax Officer. The Tribunal set aside the order of the Appellate Assistant Commissioner placing reliance on the decision of this Court in Addl. Commissioner of Income Tax	 Gujarat vs Gurjargravures P. Ltd. [1978] 111 I.T.R.I. The assessee made application before the Tribunal under Section 256(1) of the Income Tax Act	 1961 for making reference to the High Court. The Tribunal refused to refer the question on 343 the findings that the question stood covered by this Court 's decision in Gurjargravures (supra). The assessee thereupon approached the High Court under Section 256(2) of the Act for calling the statement of case and reference from the Appellate Tribunal. A Division Bench of the Calcutta High Court held that the Tribunal was right in rejecting the assessee 's application	 therefore it refused to call state ment of case. The assessee thereupon approached this Court under Article 136 of the Constitution. and obtained leave. Hence this Appeal. The question of law which the assessee sought to be referred to the High Court under Section 256(1) of the Act was: "Whether on the facts and in the circumstances of the case. the Income Tax Appellate Tribunal was justified in holding that the Appellate Assistant Commissioner of Income Tax had exceeded his powers in entertaining the additional ground of appeal taken before him in respect of the claim for deduc tion of a sum of Rs. 11	54	995 representing liability for raw jute Purchase Tax. " Section 251 of the Income Tax Act (hereinafter referred to as the 'Act ') prescribes power of the Appellate Authority hearing appeal against the order of. Income Tax Officer. Clause (a) of Section 25 1(1) confers power on the Appellate Authority namely the Appellate Assistant Commissioner [now after the Amendment of 1987 the Deputy Commissioner (Ap peals)] according to which Appellate AUthority while hearing appeal against an order of assessment. has power to confirm. reduce	 enhance or annual the assessment; he is further empowered to set aside the assessment and remit the case back to the Assessing Officer for making a fresh assessment in accordance with its directions. after making such further inquiry as may be necessary. If a direction is issued by the Appellate Authority	 the Assessing Officer is required to proceed to make such fresh assessment and determine the amount of tax	 if any. payable on the basis of fresh assess ment. The Appellate Assistant Commissioner is thus invested with wide powers under section 251(1)(a) of the Act while hearing an appeal against the order of assessment made by the Income Tax Officer. The amplitude of the power includes power to set aside the assessment order or modify the same. The question is whether the Appellate Assistant Commissioner while hearing an appeal under section 251(1)(a) has jurisdiction to allow the assessee to raise an additional ground in assailing the order of the assessment before it. The Act does not contain any express provision debarring an assessee from raising an addi 344 tional ground in appeal and there is no provision in the Act placing restriction on the power of the Appellate Authority in entertaining an additional ground in appeal. In the absence of any statutory provision. general principle relat ing to the amplitude of appellate authority 's power being co terminus with that of the initial authority should nor mally be applicable. But this question for the purposes of the Income Tax Act has been an intricate and vexed one. There is no uniformity in the judicial opinion on this question. Section 31 of the Income Tax Act	 1922 also conferred power on the Appellate Assistant Commissioner to hear appeal against the assessment order made by the Income Tax Officer. The Chagla	 CJ of the Bombay High Court considered the question in detail in Narrondas Manordass vs Commissioner of Income Tax	 and held that the Appellate Assistant Commissioner was empowered to correct the Income Tax Officer not only with regard to a matter which had been raised by the assessee but also with regard to a matter which may have been considered by the Income Tax Officer and determined in the course of the assessment. The High Court observed that since the Appellate Assistant Commissioner had revising authority against the decisions of the Income Tax Officer; a revising authority not in the narrow sense of revising those matters	 which the assessee makes a grievance but the subject matter of the appeal not only he had the same powers which could be exercised by the Income Tax Officer. These observations were approved by this Court in Commissioner of Income Tax vs McMillan & Co.	 ; the Appellate Assistant Commissioner on an appeal preferred by the assessee had jurisdiction to invoke	 for the first time provisions of Rule 33 of the Income Tax Rules	 1922	 for the purpose of computing the income of a nonresident even if the Income Tax Officer had not done so in the assessment proceedings. But in Commissioner of Income Tax	 Bombay vs Shapporji Pallon Ji Mistry	 [1962] 44 I.T.R. 891 this Court while considering the extent of the power of the Appellate Assistant Commissioner referred to a number of cases decided by various High Courts including Bombay High Court judgment in Narrondas case and also the decision of this Court in McMillan & Co. case and held that in an appeal filed by the assessee	 the Appellate Assistant Commissioner has no power to enhance the assessment by discovering new sources of income	 not considered by the Income Tax Officer in the order appealed against. It was urged on behalf of the Revenue that the words "enhance the assessment" occurring in section 31 were not confined to the assessment reached through particular process but the amount which ought to have been computed if the true total income had been 345 found. " The Court observed that there was no doubt that this view was also possible	 but having regard to the provisions of Sections 34 and 33B	 which made provisions for assessment of escaped income from new sources	 the interpretation suggested on behalf of the Revenue would be against the view which had held the field for nearly 37 years. In this view the Court held that the Appellate Assistant Commissioner had no power to enhance the assessment by discovering new sources of income. This decision does not directly deal with the question which we are concerned. Power to enhance Tax on discovery of new source of income is quite different than granting deduction on the admitted facts fully supported by the decision of this Court. If the tax liability of the assessee is admitted and if the Income Tax Officer is af forded opportunity of hearing by the Appellate Authority is allowing the assessee 's claim for deduction on the settled view of law	 these appears to be no good reason to curtail the powers of the appellate authority under Section 25 1(1)(a) of the Act. In Commissioner of Income Tax	 U.P.v. Kanpur Coal Syndi cate	 a three Judge Bench of this Court discussed the scope of Section 31(3)(a) of the Income Tax Act	 1922 which is almost identical to Section 251(1)(a). The Court held as under: "If an appeal	 lies	 Section 31 of the Act describes the powers of the Appellate Assistant Commissioner in such an appeal. Under Section 31(3)(a) in disposing of such an appeal the Appellate Assistant Commissioner may	 in the case of an order of assessment	 confirm	 reduce	 enhance or annul the assessment; under clause (b) thereof he may set aside the assessment and direct the Income Tax Officer to make a fresh assessment. The Appellate Assistant Commissioner has	 therefore	 plenary powers in disposing of an appeal. The scope of his power is conterminous with that of the Income Tax Officer. He can do what the Income Tax Officer can do and also direct him to do what he has failed tO do. " (emphasis supplied) The above observations are squarely applicable to the interpretation of section 25 1(1)(a) of the Act. The declaration of law is clear that the power of the Appellate Assistant Commissioner is co terminus with that of the Income Tax Officer	 if that he so	 there appears to be no reason as to why the appellate authority cannot modify the assessment order on an additional ground even if not raised before the Income Tax Officer. No 346 exception could be taken to this view as the Act does not place any restriction or limitation on the exercise of appellate power. Even otherwise an Appellate Authority while hearing appeal against the order of a subordinate authority has all the powers which the original authority may have in deciding the question before it subject to the restrictions or limitations if any prescribed by the statutory provi sions. In the absence of any statutory provision the Appel late Authority is vested with all the plenary powers which the subordinate authority may have in the matter. There appears to be no good reason and none was placed before us to justify curtailment of the power of the Appellate Assist ant Commissioner in entertaining an additional ground raised by the assessee in seeking modification of the order of assessment passed by the Income Tax Officer. In Additional Commissioner of Income Tax	 Gujarat vs Gurjargravures P. Ltd. (supra) this Court has taken a dif ferent view	 holding that in the absence of any claim made by the assessee before the Income Tax Officer regarding relief	 he is not entitled to raise the question of exemp tion under Section 84 before the Appellate Assistant Commis sioner hearing appeal against the order of Income Tax Offi cer. In that case the assessee had made no claim before the Income Tax Officer for exemption under Section 84 of the Act	 no such claim was made in the return nor any material was placed on record supporting such a claim before the Income Tax Officer at the time of assessment. The assessee for the first time made claim for exemption under Section 84 before the Appellate Assistant Commissioner who rejected the claim but on further appeal the Appellate Tribunal held that since the entire assessment was open before the Appellate Assistant Commissioner there was no reason for his not entertaining the claim	 or directing the Income Tax Officer to allow appropriate relief. On a reference the High Court upheld the view taken by the Tribunal. On appeal this Court set aside the order of the High Court as it was of the view that the Appellate Assistant Commissioner had no power to interfere with the order of assessment made by Income Tax Officer on a new ground not raised before the Income Tax Officer	 and therefore the Tribunal committed error in directing the Appellate Assistant Commissioner to allow the claim of the assessee under Section 84 of the Act. Apparent ly this view taken by two Judge Bench of this Court appears to be in conflict with the view taken by the three Judge Bench of the Court in Kanpur Coal Syndicate 's case (supra). It appears from the report of the decision in Gujarat case the three Judge Bench decision in Kanpur Coal Syndicate (supra) case was not brought to the notice of the Bench in the Gurjargravures P. Ltd. (supra). In the 347 circumstances the view of the larger Bench in the Kanpur Coal Syndicate	 (supra) holds the field. However we do not consider it necessary to over rule the view taken in Gurjar gravures P. Ltd. (supra) case as in our opinion that deci sion is rounded on the special facts of the case	 as would appear from the following observations made by the Court; "As we have pointed out earlier	 the statement of case drawn up by the Tribunal does not mention that there was any material on record to sustain the claim for exemption which was made for the first time before the Appellate Assistant Commissioner. We are not here called upon to consider a case where the assessee failed to make a claim though there was no evidence on record to support it	 or a case where a claim was made but no evidence or insufficient evidence was ad duced in support. In the present case neither any claim was made before the Income Tax Officer	 nor was there any mate rial on record supporting such a claim. " The above observa tions do not rule out a case for raising an additional ground before the Appellate Assistant Commissioner if the ground so raised could not have been raised at that particu lar stage when the return was filed or when the assessment order was made	 or that the ground became available on account of change of circumstances or law. There may be several factors justifying raising of such new plea in appeal	 and each case has to be considered on its own facts. If the Appellate Assistant Commissioner is satisfied he would be acting within his jurisdiction in considering the question so raised in all its aspects. Of course	 while permitting the assessee to raise an additional ground	 the Appellate Assistant Commissioner should exercise his discre tion in accordance with law and reason. He must be satisfied that the ground raised was bona fide and that the same could not have been raised earlier for good reasons. The satisfac tion of the Appellate Assistant Commissioner depends upon the facts and circumstances of each case and no rigid prin ciples or any hard and fast rule can be laid down for this purpose. In Rai Kumar Srimal vs Commissioner of Income Tax	 West Bengal 111	 a Division Bench of Cal cutta High Court presided over by Sabyasachi Mukharji	 J.	 as he then was held that the Appellate Assistant Commission er was entitled to admit new ground or evidence either suo motu or at the invitation of the parties. If he is acting on being invited by the assessee	 then there must be some ground for admitting new evidence in the sense that there must be some explanation to show that the failure to adduce earlier the evidence sought to be adduced before the Appel late Assistant Commissioner was not wilful and not unreason able. This view is reasonable and it finds favour with us. 348 In the instant case the assessee was carrying on manu facture and sale of jute. In the assessment year of 1974 75 he did not claim any deduction on its liability to pay Purchase Tax under the provisions of the Bengal Raw Jute Taxation Act	 1941	 as the appellant entertained a belief that it was not liable to pay Purchase Tax under the afore said Act. But later on it was assessed to Purchase Tax and the order of assessment was received by it on 23.11. The appellant disputed the demand and filed an appeal before the Appellate Authority and obtained stay order. The asses see thereafter claimed deduction for the amount of Rs. 11	54	995 towards his liability to pay Purchase Tax as deduction for the assessment year 1974 75. The assessee had not actually paid the Purchase Tax as he had obtained stay from the Appellate Authority nonetheless its liability to pay tax existed	 and it was entitled to deduction of Rs. 11	54	995 as was held by this Court in Kedarnath Jute Mfg. Co. Ltd. vs Commissioner of Income Tax (Central)	 Calcutta	 There was no dispute about these facts. In these circumstances the Appellate Assistant Com missioner allowed the assessee to raise this question and after hearing the Income Tax Officer	 he granted the deduc tion from the assessee 's income. The Tribunal took a con trary view placing reliance on the decision of this Court in Gujargravures P. Ltd. (supra). As already discussed the facts in the instant case are quite clear	 unlike the facts involved in Gurjargravures case. We are	 therefore	 of the view that the view taken by the Appellate Tribunal and the High Court is not sustainable in law. In our opinion	 the High Court and Tribunal both committed error in refusing to state the case	 or making a reference. The next question which arises for consideration is to know what order should be passed in the present circum stances. In view of the findings recorded by us ordinarily we should direct the High Court to call for the statement of case from the Tribunal and thereupon decide the matter afresh	 but this procedure would be time consuming. Since we have already discussed the correct position of law we do not consider it necessary to follow the usual procedure. Since the view taken by the Income Tax Appellate Tribunal is not sustainable in law we grant leave against the order of the Appellate Income Tax Tribunal under Article 136 and set aside the same and remit the matter to the Appellate Income Tax Tribunal to consider the merit of the deduction permit ted by the Appellate Assistant Commissioner. If the Tribunal thinks it necessary it may remand the matter to the Appel late Assistant Commissioner (now Deputy Commissioner of Appeals) for reheating. The appeal is accordingly disposed of. There will be no order as to costs. G.N. Appeal disposed of.

In respect of the assessment for the assessment year 1974 75	 the appellant assessee preferred an appeal before the Appellate Assistant Commissioner. During the hearing of the appeal	 the assessee raised an additional ground as regards its liability to Purchase Tax and claimed a deduc tion of Rs.11	54	995. After giving an opportunity of hearing to the Income Tax Officer	 the Appellate Assistant Commis sioner allowed the said claim. The Revenue preferred an appeal before the Income Tax Appellate Tribunal. The Tribunal held that the Appellate Assistant Commissioner had no jurisdiction to entertain any additional ground not raised before the Income Tax Officer and set aside the order of the Appellate Assistant Commis sioner. The assessee 's application for making reference to the High Court was refused by the Tribunal. The High Court also rejected the assessee 's application for calling the state ment of the case and reference from the Tribunal. Hence	 this appeal by special leave. Disposing of the appeal	 the Court	 HELD: 1.1 The declaration of law is clear that the power of the Appellate Assistant Commissioner is co terminus with that of the Income Tax Officer. If that be so	 there appears to be no reason as to why the appellate authority cannot modify the assessment order on an additional ground even if not raised before the Income Tax Officer. No exception could be taken to this view as the Act does not place any restric tion or limitation on the exercise of appellate power. Even otherwise an Appellate Authority while hearing appeal against the order of a subordinate authority has all the powers which the original 341 authority may have in deciding the question before it sub ject to the restrictions or limitation if any prescribed by the statutory provisions. In the absence of any statutory provisions to the contrary the Appellate Authority is vested with all the plenary powers which the subordinate authority may have in the matter. [155G H; 156A B] 1.2 If the Appellate Assistant Commissioner is satisfied he would be acting within his jurisdiction in considering the question so raised in all its aspects. Of course	 while permitting the assessee to raise an additional ground	 the Appellate Assistant Commissioner should exercise his discre tion in accordance with law and reason. He must be satisfied that the ground raised was bona fide and that the same could not have been raised earlier for good reasons. The satisfac tion of the Appellate Assistant Commissioner depends upon the facts and circumstances of each case and no rigid prin ciples or any hard and fast rules can be laid down for this purpose.

In the instant case	 the assessee was assessed to Purchase Tax. The appellant disputed the demand and filed an appeal before the Appellate Authority and obtained stay order. The assessee thereafter claimed deduction for the amount of Rs.11	54	995 towards his liability to pay Purchase Tax as deduction for the assessment year 1974 75. The asses see had not actually paid the Purchase Tax as it had ob tained stay from the Appellate Authority; nonetheless its liability to pay tax existed	 and it was entitled to deduc tion of Rs. 11	54	995. [158B C] 3. Since the view taken by the Income Tax Appellate Tribunal is 342 not sustainable in law	 the order of the Tribunal is set aside and the matter is remitted to the Tribunal to consider the merit of the deduction permitted by the Appellate As sistant Commissioner.
