Summarize the following court judgment. vil Appeal No. 41819 of 1989. From the Judgment and Order dated 29.4.1988 of the Gujarat High Court in F.A. Nos. 848 849 of 1986. V.B. Patel	 D. Patel	 T.H Pandey and R.P. Kapur for the Appellant. Soli J. Sorabjee	 Atul Setalwad	 N.J. Mehta	 P. Shah	 S.K. Sharma	 section Sharma and P.H. Parekh for the Respondents. The Judgment of the Court was delivered by SABYASACHI MUKHARJI	 J. This is an application for leave to appeal under Article 136 of the Constitution from the judgment and order of the High Court of Gujarat dated 29th April	 1988. To appreciate the questions involved herein	 few facts have to be emphasized. In 1978	 the State Government of Gujarat undertook a scheme known as 'Bhavnagar City Water Supply Scheme '. The 322 Scheme was divided into two parts: (i) Raising Main; and (ii) Gravity Main. Raising Main was divided into two sec tions	 namely	 10.1 k.ms. and 7.4 k.ms. steel welded pipe line. On or about 15/16th December	 1978	 the State Govern ment issued letter of approval to the bargain between the parties on certain terms. On 12th January	 1979	 two contracts were awarded to the respondent No. 1 for Rs. 1	29	39	691 and Rs.94	30	435 which provided the dates of completion as February 1979 and the 3rd week of September	 1980 respectively. On 29th March	 1981 the respondent No. 1 filed the Civil Suit No. 588 of 1981 in the City Civil Court with regard to measurements recorded by the Deputy Engineer and alleged underpayments. On 4th June	 1981	 the respondent No. 1 gave notice to the State Government and the petitioner Board requesting for reference of the alleged disputes to the arbitrator under clause 30 of the agreement. On or about 8th July	 198 1 the respondent No. 1 gave notice under Section 8 of the Arbitra tion Act	 1940 (hereinafter called 'the Act ') calling upon the petitioner to concur in the appointment of one Shri G.G. Vaidhya. On 21st July	 1981	 he withdrew the Civil Suit No. 588 of 1981. On 6th August	 1981	 the respondent No. 1 filed Civil Miscellaneous Application No. 231 of 1981 in the Court of Civil Judge	 (SD)	 Ahmedabad for appointment of the said Shri G.G. Vaidhya as the sole arbitrator. On 7th November 1981	 the petitioner filed reply contesting the arbitrabili ty of the various claims made in the application and inter alia contending that the application was not maintainable. On or about 15th December	 1981 the learned Civil Judge appointed Shri G.G. Vaidhya as the sole arbitrator with a direction that he should first decide as to which disputes fell within the purview of clause 30 of the agreement. On 5th May	 1982	 Shri Vaidhya gave an interim award holding that the claims at section Nos. 10(g) and 10(1) only were not arbitrable and further that the other claims were arbitra ble. A petition was filed in High Court which was dismissed and then there was an application to this Court under Arti cle 136 of the Constitution which was disposed of by consent on 30th November	 1983. The said order inter alia provided that the parties had agreed to settle the matter amicably and one Shri Mohanbhai D. Patel	 Retired Secretary	 Public Works Department	 Gujarat and at that time Sitting Member of the petitioner Board was appointed as the sole arbitrator in place of Shri Vaidhya to decide all disputes between the parties relating to the following works: "i) providing	 fabricating	 laying and joint ing 1000 mm dia. 10	000 M long steel welded pipe line under Bhavnagar 323 Emergency Water Supply Scheme based on She trunji Dam Agreement No. 5/2 1 of 1978 79. ii) providing	 fabricating laying and jointing 1000 mm dia 7	400 M long steel welded pipe line under Bhavnagar Emergency Water Supply Scheme based on Shetrunji Dam Agreement No. B 2/2 of 1978 79. " It was further provided that all disputes concerning the said two works in question should be referred to the sole arbitrator and the Board could also be entitled to put counter claims before him. The consent terms also provided the following terms: "That the arbitration proceedings shall be started de novo meaning thereby that the earlier appointment and proceedings before the Sole Arbitrator Shit G.G. Vaidhya shall be inoperative and void. That the Board shall have a right to agitate all points both in fact and in law before the Sole Arbitrator as per the terms and condi tions of the contract including the question of arbitrability within the meaning of clause 30 of the contract. Both parties shall have a right to be repre sented by an Advocate and/or their representa tives. The expenses of arbitration shall be borne by .both the parties as per rules of Govern ment in this behalf. That both parties shall agree to extend time as and when necessary for competition of arbitration proceedings. That a formal agreement for arbitration shall be executed between the parties defining the scope of Arbitration. _ That the provisions of the Indian shall apply to the proceedings before this Sole Arbitrator." On 31st March	 1984	 Shri M.D. Patel was appointed as the sole arbitrator jointly by the parties	 and on 2nd April	 1984 he accepted his appointment and directed the parties to file their claim statements within 15 days. Thereafter	 the respondent No. 1 filed claim to the tune of Rs.4	92	20	683 and a counter claim to the extent of 324 Rs.26	87	217.40. On 22nd August	 1984 the parties appeared before the arbitrator after filing of claims and counter claims. On 1st October	 1984 the petitioner filed an application before the arbitrator praying that preliminary issues be raised and decided first as to which of the disputes were arbitrable under clause 30 Of the agreement. On 8th July	 1985	 a lumpsum award was made by the arbitrator	 and on 19th July	 1985 the parties were informed about the signing of the award. On the same day the award filed by the re spondent No.1 's Advocate which was dated 8.7.1985 was regis tered as Civil Miscellaneous Application No. 144/85. There after	 notice was issued on the same day and served on the petitioner also on the same day. The petitioner filed objec tions to the award and the Objection Petition was registered as Civil Miscellaneous Application No. 158/85. Reply to the objections was filed by the respondent No. 1. On 17th June	 1986	 however	 the learned Civil Judge directed that decree be passed in terms of the award. Two appeals were filed by the petitioner. On the 29th April	 1988 the High Court by a judgment dismissed the petition challenging the award and upheld the award. Aggrieved thereby	 the petitioner has moved this Court as mentioned hereinbefore. Various grounds were urged in support of this applica tion. It was contended	 firstly	 that there was an error apparent on the face of the award and that the award was bad. It was submitted that the arbitrator had committed an error of law in not deciding or disclosing his mind about the arbitrability of claims or counter claims	 more so when the Board 's application for deciding the same	 was pending before the arbitrator. Before the learned Trial Judge the Board had submitted an application to the arbitrator seeking to raise a preliminary issue regarding arbitrability of the claims. As noted by the learned Trial Judge	 it appears that the third meeting specifically mentioned that the claims were placed before the arbitrator and their contentions about the arbitrability were considered. So	 these issues were gone into and it appears that the parties had agreed and proceeded on the basis that the claims may be examined and it was not necessary to decide preissue of arbitrability and it was agreed that aH the claims be decided claimwise. So	 it cannot be said that the arbitrator had acted arbi trarily in discussing all the questions raised before him without first deciding the question of arbitrability or non arbitrability of an issue as such. The Court in its judgment has discussed the conduct of the parties. It appears that the Court found that the par ties themselves had 325 agreed that the arbitrator should decide claimwise and on merit. The Court so found	 and in or opinion	 rightly. The arbitrator so proceeded. There was no error committed by the arbitrator in so conducting himself. It was	 secondly	 contended that out of the numerous claims before the arbi trator	 some of which	 according to the petitioner	 were ex facie not arbitrable and some were withdrawn including the claims for interest of Rs.54	61	073 and compound interest of Rs.82	26	039. and in the award no basis or indication was given as to which claim was rejected and further of the amount which was awarded as claim and what amount towards element of interest. It was	 thirdly	 contended that there was an error apparent on the face of the award inasmuch as the basis on which interest has been awarded has not been disclosed and whether the interest has been awarded from the date of the institution of the proceedings. It was	 fourth ly	 contended that granting of interest pendente lite was contrary to the decision of this Court. It was	 lastly	 contended that non speaking award had resulted in great prejudice inasmuch as against the claim of Rs. 1 lakh	 Rs.57 lakhs have been awarded. The scope and extent of examination by the Court of the award made by an arbitrator has been laid down in various decisions. It has to be noted that there is a trend in modern times that reasons should be stated in the award though the question whether the reasons are necessary in ordinary arbitration awards between the parties is pending adjudication by the Constitution bench of this Court. Even	 however	 if it be held that it is obligatory for the arbi trator to state reasons	 it is not obligatory to give any detailed judgment. An award of an arbitrator should be read reasonably as a whole to find out the implication and the meaning thereof. Short intelligible indications of the grounds should be discernible to find out the mind of the arbitrator for his action even if it be enjoined that in all cases of award by any arbitrator reasons have to be stated. The reasons should not only be intelligible but should also deal either expressly or impliedly with the substantial points that have been raised. Even in a case where the arbitrator has to state reasons	 the sufficiency of the reasons depends upon the facts and the circumstances of the case. The Court	 however	 does not sit in appeal over the award and review the reasons. The Court can set aside the award only if it is apparent from the award that there is no evidence to support the conclusion or if the award is based upon any legal proposition which is erroneous. See the observations of this Court in Indian Oil Corporation Ltd. vs Indian Carbon Ltd.; 	 326 In the instant case	 the arbitrator by virtue of the terms mentioned in the order of this Court had to decide which of the disputes were arbitrable and which were not. It is true that the arbitrator has not specifically stated in the award that he had to decide the question of arbitrabili ty. The arbitrator has rested by stating that he had heard the parties on the point of arbitrability of the claim and the 	counter claim. He has further stated that after 'con sidering all the above aspects ' and 'the question of arbi trability or non arbitrability ' he had made the award on certain aspects. Reading the award along with the preamble	 it appears clear that the arbitrator had decided the arbi trability and the amount he has awarded was on the points which were arbitrable. The contention that the arbitrator had not decided the question of arbitrability as a prelimi nary issue cannot also be sustained. A reference to the arbitrator 's proceedings which were discussed in detail by the High Court in the judgment under appeal reveal that the procedure adopted by the arbitrator	 i.e.	 that he will finally decide the matters	 indicated that the parties had agreed to and the arbitrator had proceeded with the consent of the parties in deciding the issues before him and in not deciding the question of arbitrability as a separate	 dis tinct and preliminary issue. The arbitrator has made his award beating all the aspects including the question of arbitrability in mind. It was contended before us that the arbitrator has made a non speaking award. It was obliged to make a speaking award	 it was submitted by terms of the order of this Court. We cannot sustain this submission because it is not obligatory as yet for the arbitrator to give reasons in his decision. The arbitrator	 however	 has in this case indicated his mind. It appears to us that the point that the non speaking award is per se bad was not agitated before the High Court. We come to that conclusion from the perusal of the judgment under appeal though	 howev er	 this point has not been taken in the appellant 's appeal. It is one thing to say that an award is unintelligible and is another to say that the award was bad because it was a non speaking award. The point taken was that the award was unintelligible and not that it was non speaking. But there was nothing unintelligible about the award. We were invited to refer the matter to the Constitution Bench and await the disposal of this point by the Constitu tion Bench. The contract in this case was entered into in 1978. The proceedings for initiation of arbitration started in 1981. The matter had come up to this Court before which resulted in the order dated 30th November	 1983. Pursuant thereto	 the award has been made and no grounds specifically were urged though they were taken in the appeal in the High 327 Court in the arguments before the High Court about the award being bad because it is non speaking. In those circum stances	 it will not be in consonance with justice for us to refer the matter to the Constitution Bench or to await the disposal of the point by the Constitution Bench. It was further submitted before us that the award was unreasonable and that the arbitrator had awarded a large amount to money but the original claim was not so large and as such the award was disproportionate. This contention	 as it is	 it appears from the judgment of the High Court	 was not urged and canvassed before the High Court. The claim and the counter claim together in its totality	 in our opinion	 does not make the award amount disproportionate. Reasonableness as such of an award unless the award is per se preposterous or absurd is not a matter for the court to consider. Ap praisement of evidence by the arbitrator is ordinarily not a matter for the court. It is difficult to give an exact definition of the word 'reasonable '. Reason varies in its conclusions according to the idiosyncrasy of the individual and the times and the circumstances in which he thinks. The word 'reasonable ' has in law prima facie meaning of reasona ble in regard to those circumstances of which the actor	 called upon to act reasonably	 knows or ought to know. See the observations on this point in Municipal Corporation of Delhi vs M/s. Jagan Nath Ashok Kumar & Anr.	 ; Judged by the aforesaid yardstick the award cannot be condemned as unreasonable. There is	 however	 one infirmity in the award which is apparent on the face of the award which in the interest of justice as the law now stands declared by this Court	 we should correct	 viz.	 the question of interest pendente lite. The right to get interest without the intervention of the Court and the powers of the court to grant interest on judgment have been examined by this Court in Executive Engineer (Irrigation) Balimela and Ors. vs Abhaduta Jena & Ors.	 [1988] 1 SCC 418 which observations were also followed by this Court in State of Orissa & Ors. vs Construction India	 [1987] Supp. SCC 709. In accordance with the princi ples stated therein and the facts in this case	 it appears that the principal amount awarded is Rs.57	65	273. This is confirmed. In this case	 2nd April	 1984 is the date of the reference to arbitration	 on 22nd August	 1984 the arbitra tor entered upon the reference. 8th July	 1985 is the date of the award and 19th July	 1985	 is the date of the publi cation of the award. The interest awarded	 in the instant case	 covers three periods: (i) 6th August	 1981 to 21st August	 1984 prior to the commencement of the arbitration proceedings; (ii) 22nd August	 1984 to 19th July	 328 1985 pendente lite; and (iii) 19th July	 1985 to 17th June	 1986 (date of award to date of decree). Having regard to the position in law emerging from the decision of this Court in Executive Engineer (Irrigation) Balimela & Ors. (supra) and section 29 of the and section 34 of the Code of Civil Procedure	 we would modify the grant of interest in this case. The arbi trator has directed interest to be paid at 17% per annum from 6.8.1981 upto the date of decree viz.	 17.6.1986. Since in this case the reference to arbitration was made after the commencement of the 	 the arbitrator under section 3(1)(a) of the said Act was entitled to award inter est from 6.8.1981 till 21.8.1984 in view of this Court 's decision in Abhaduta Jena 's case (supra). In the light of the same decision	 he could not have awarded interest for the period from 22.8.1984 till the date of the publication of the award viz. 19.7. So far as interest for the period from the date of the award (19.7.1985) till the date of the decree is concerned	 the question was not specifical ly considered in Abhaduta Jena 's case (supra) but special leave had been refused against the order in so far as it allowed interest for this period. We think interest should be allowed for this period	 on the principle that this Court can	 once proceedings under sections 15 to 17 are initiated	 grant interest pending the litigation before it	 i.e.	 from the date of the award to the date of the decree. It may be doubtful whether this can be done in cases arising before the in view of the restricted scope of section 29 of the . But there can be no doubt about the court 's power to grant this interest in cases governed by the as section 3(1)(a) which was applied by Abhaduta Jena to arbitrators will equally apply to enable this Court to do this in these proceedings. In this connection	 it is necessary to consider whether the date of commencement of the arbitration proceedings should be taken as the date of the reference or the date on which the arbitrator entered upon the reference as the date of the calculation of interest. In this case	 the proceed ings commenced on 2nd April	 1984 and the arbitrator entered upon the reference on 22nd August	 1984. Having regard to the facts and the circumstances of the case	 it is neces sary	 in our opinion	 to take 22nd August	 1984 as the date. It is also necessary to consider whether the date of award should be taken as the date of its making or its publica tion. The award was made on 8th July	 1985 and it was pub lished on 19th July	 1985	 and	 therefore	 the latter date would be taken as the date of the award. 329 We would	 however	 delete the interest awarded by the arbitrator for the period from 22.8.1984 till the date of the award and confine the interest on the principal sum of Rs.57	65	273 to interest at 9 per cent from 6.8.1981 till 21.8.1984 (which has been worked out at Rs.29	82	443). However	 in exercise of our powers under section 3 of the and section 29 of the 	 we direct that the above principal sum or the unpaid part thereof should carry interest at the same rate from the date of the award (19.7.1985) till the date of actual pay ment. The appeals are disposed of in the above terms. N.V.K. Appeals disposed of.

In 1978 the State Government undertook the construction of the 'Bhavnagar City Water Supply Scheme '	 and on 12th January	 1979	 two contracts in respect thereof were awarded to respondent No. 1. On 29th March	 1981	 respondent No. 1 filed a civil suit with regard to measurements recorded by the Deputy Engineer and alleged underpayments. On 14th June	 1981	 he gave notice to the State Government and the peti tioner Board requesting for reference of the disputes to an arbitrator as provided for under clause 30 of the Agreement	 and gave notice under section 8 of the calling upon the petitioner to concur in the appointment of one Shri G.G. Vaidhya. On 6th August	 1981 respondent No. 1 filed a civil miscellaneous application for appointment of the said Shri G.G. Vaidhya as the sole arbitrator after withdrawing the civil suit. The petitioner contended that the application was not maintainable. The Civil Judge howev er appointed the said Shri G.G. Vaidhya as sole arbitrator. The arbitrator gave an interim award holding that only two claims were not arbitrable and that the other claims were arbitrable. The High Court having dismissed the appeal	 a further appeal was filed in this Court. This appeal was	 however	 disposed of by con 319 sent on 30th November	 1983 to the effect that a retired Secretary	 Public Department who was at that time sitting member of the petitioner Board be appointed as the sole arbitrator to decide all the disputes between the parties. On 8th July	 1985	 this sole arbitrator made a lump sum award. The Civil Judge directed that the decree be passed in terms of the award	 rejecting the objections of the peti tioner. The High Court by a common judgment dismissed the two appeals of the petitioner challenging the award. In the appeals to this Court by special leave	 it was contended: (1) that the arbitrator had committed an error of law in not deciding or disclosing his mind about the arbi trability of the claim or counterclaims	 (2) in the award no basis or indication was given as to which claim was reject ed	 and further what amount was awarded as claim and what amount towards element of interest	 (3) there was an error apparent on the face of the award inasmuch as the basis on which interest had been awarded had not been disclosed and whether the interest has been awarded from the date of the institution of the proceedings	 (4) that the granting of interest pendente lite was contrary to the decision of this Court and (5) that the non speaking award had resulted in great prejudice to the petitioner inasmuch as against the claim of Rs.1 lakh	 Rs.57 lakhs had been awarded. Disposing of the appeals	 the Court	 HELD: 1(a) There is a trend in modern times that reasons should be stated in the award though the question whether the reasons are necessary in ordinary arbitration awards is pending adjudication by the Constitution Bench of this Court. Even if it be held that it is obligatory for the arbitrator to state reasons	 it is not obligatory to give any detailed judgment. [325E] 1(b) An award Of an arbitrator should be read reasonably as a whole to find out the implication and the meaning thereof. Short intelligible indications of the grounds shall be discernible to find out the mind of the arbitrator for his action. [325F] l(c) The Court does not sit in appeal over the award and review the reasons. The Court can set aside the award only if it is apparent from the award that there is no evidence to support the conclusion or if the award is based upon any legal proposition which is erroneous. [325G H] 320 Indian Oil Corporation Ltd. vs Indian Corbon Ltd.	 ; 	 referred to. l(d) It is one thing to say that an award is unintelli gible and it is another thing to say that the award was bad because it was a nonspeaking award. [326F] In the instant case	 the arbitrator	 in pursuance to the order of this Court had to decide which of the disputes were arbitrable and which were not. Reading the award along with the preamble	 it appears clear that the arbitrator had decided the arbitrability and the amount which he has award ed was on the points which were arbitrable. In such circum stances it will not be in consonance with justice to refer the matter to the Constitution Bench or to await the dispos al of the point by the Constitution Bench. [326B	 G] 2. Reasonableness as such of an award unless per se preposterous or absurd is not a matter for the Court to consider. Appraisement of evidence by the arbitrator is ordinarily not a matter for the Court. It is difficult to give an exact definition of the word 'reasonable '. The word 'reasonable ' has in law	 prima facie meaning of reasonable in regard to those circumstances of which the actor	 called upon to act reasonably	 knows or ought to know. The award in the instant case cannot be condemned as unreasonable. [327C D] Municipal Corporation of Delhi vs M/s. Jagan Nath Ashok Kumar & Anr.	 ; referred to. The grant of interest pendente lite is however one infirmity in. the award which is apparent on the face of the award which in the interest of justice should be corrected. [327E] Executive Engineer (Irrigation) Balimela and Ors. vs Abhaduta Jena & Ors.	 [1988] 1 SCC 418 and State of Orissa & Ors. vs Construction India	 [1987] Supp. SCC 709 referred to. In the instant case	 April 2	 1984 is the date of the reference to arbitration	 on August 22	 1984 the arbitrator entered upon the reference. July 8	 1985 is the date of the award and July 19	 1985 the date of publication of the award. The latter date should be taken as the date of the award. Since the reference to arbitration was made after the commencement of the the arbitrator under section 3(1)(a) of the said Act was entitled to award inter est from August 6	 321 1981 till August 21	 1984. He could not have awarded inter est for the period from August 22	 1984 till the date of publication of the award viz. July 19	 1985. [327G H; 328A] 4. So far as interest for the period from the date of the award (July 19	 1985) till the date of the decree is concerned	 interest should be allowed for this period	 on the principle that this Court can	 once proceeding under sections 15 to 17 are initiated	 grant interest pending the litigation before it	 i.e. from the date of the award to the date of the decree. It may be doubtful whether this can be done ln cases arising before the in view of the restricted scope of section 29 of the . [328D E] 5. The interest awarded by the arbitrator for the period from August 22	 1984 till the date of award is deleted; and the interest on the principal sum is confined to 9% from August 6	 1981 till August 21	 1984. However	 exercising powers under section 3 of the and section 29 of the 	 the Court directed that the principal sum or unpaid part thereof should carry interest at the same rate from the date of the award (July 19	 1985) till the date of actual payment.
