Summarize the following court judgment. o. 1040 of 1968. Appeal by special leave from the Award dated September 16	 1967 of the Third Industrial Tribunal	 West Bengal in Case No. VIII 235/66. Debabrata Mookherjee	 Janardan Sharma and Anil Das Chow dhury	 for the appellants. C. K. Daphtary and M. C. Bhandare	 B. P. Maheshwari and Leila Sheth	 for the respondent. The Judgment of the Court was delivered by Vaidialingam J. In this 'appeal	 by special leave	 the short question that arises for consideration is whether the appellants are precluded by section 32 (vii) (a) of the (hereinafter to be referred as the Act) from claiming bonus under the Act in view of the agreement exhibit A5 dated August 30	 1962. The respondent Company is a fairly prosperous concern and one of the biggest of its kind in Asia. It has factories at Batanagar in West Bengal	 Faridabad in the present Haryana State	 Digha and Mokamehghat in Bihar and Administrative Offices in Calcutta. It has Central Repair shops in Calcutta and other places and a Purchasing Depot in Kerala. It has about 900 shops for retail sale scattered throughout the country besides the wholesale agents. Its branches have a wide market both in this country as well as abroad. It employs a very large number of workmen in its factory	 Administrative Office and Central Repair Shops. The Company and the appellants	 represented by its Unions have been entering into various agreements from time to time	 the last of which was on August 30	 As per exhibit A.5 the respondent paid bonus for the year 1964 at the rates mentioned therein. The appellants demanded that they should be paid the profit bonus as per the Act in addition to what has been paid as 452 per exhibit A.5 The Company declined to accede to the demand of the workmen on the ground that the general bonus paid under exhibit A.5 was an amount paid as production bonus or incentive wages. The Company also pleaded section 32 (vii) (a) as a bar to the workmen making a claim for payment of bonus under the Act. During the conciliation proceedings the Union and the Company agreed to have the dispute referred for adjudication to the Industrial Tribunal. Accordingly	 the State Government on June 25	 1966	 referred to the Third Industrial Tribunal	 West Bengal	 for adjudication the following dispute : "Whether the employees of the Company represented by Bata Mazdoor Union are entitled to Bonus for the year	 1964 under the in addition to the Bonus paid to them and whether in view of the Agreement dated the 30th August	 1962	 between the Union and the Company for payment of Bonus	 the is applicable to such employees. " Before the Tribunal the appellants ' plea was that the amount paid under the agreement exhibit A. 5 is an ad hoc or an ex gratia payment made out of charity and as a supplement to the wages and that it was not a bonus linked with production or productivity. It was not an annual payment	 nor was it paid in lieu of bonus based on profits. The workmen accepted the position that the general bonus paid under the agreement was neither customary nor a profit bonus; nor a bonus as an implied term of contract. On all these grounds the workmen pleaded that section 32 (vii) (a) is no bar to their claim for bonus under the Act. The Company on the other hand	 after a reference to the various prior agreements	 under which the amounts have been paid as bonus	 though under different names	 pleaded that the general bonus paid under the agreement exhibit A5 was an amount paid as production bonus or incentive wages. The Company placed considerable reliance on the minutes of the discussions that took place between the Union and the Company whenever demands were raised and the agreements arrived at between the parties	 which were later on incorporated as formal settlements from time to time. These proceedings were relied on by the Company for the purpose of showing that the demands for payment of bonus were as pro duction bonus and that what was ultimately paid under the various agreements including the one in question	 namely	 exhibit A.5 were all understood by all parties as production bonus or incentive wages. As the necessary conditions required under section 32 (vii) (a) were present in this case	 according to the Company	 the claim for profit bonus under the Act is not sustainable. 453 The Industrial Tribunal	 after a fairly elaborate consideration of the various agreements as well the record of the proceedings leading upto those agreements and the other materials on record has held in its award that the general bonus that was being paid by the Company including the payment of bonus under the agreement exhibit A.5 was not a profit sharing bonus. The Tribunal has found that the general bonus paid under the agreement of 1962 was an annual bonus linked with production or productivity and that it was paid in lieu of bonus based on profits. The mere cir cumstance that the payment of bonus was made quarterly	 according to the Tribunal	 does not take it away from the nature of an annual payment. The Tribunal ultimately held that in view of the agreement exhibit A.5 the workmen are not entitled to claim bonus for the year 1964 under the Act. On behalf of the appellants Mr. D. Mookerjee	 learned coun sel	 very strenuously criticised the reference made by the Tribunal to the previous agreements for interpreting the nature of the payment under exhibit A.5. It was contended that the Tribunal having held that the agreement of 1962 was a self contained agreement	 committed a very serious error in law in interpreting the term "General Bonus" occurring in the said agreement by reference to the previous agreements. According to Mr. Mookerjee	 the Tribunal should have considered the nature of the payment by a reference only to the provisions contained in the agreement of 1962. Read in that manner	 it was pointed out	 the inevitable conclusion should be that the general bonus paid under the agreement of 1962 was not an annual bonus	 nor was it linked with production or productivity and it has not been paid in lieu of bonus based on profits. The general bonus paid does not satisfy the test of production bonus as laid down by this Court. The payments admittedly being made quarterly do not have the character of an annual bonus. There is no material on record to show that the Company paid the amount under the agreement in lieu of bonus based on profits. the contention taken before the Tribunal by the workmen that the amount paid under the agreement was only an ex gratia payment to supplement the wage bill of the workmen without any relation to production or productivity was also pressed before us by the counsel. On the other hand	 Mr. C. K. Daphtary	 learned counsel for the respondent Company	 pointed out that in order to appreciate and decide about the character of the general	 bonus paid under the agreement of 1962	 it was not only necessary but also obligatory on the part of the Tribunal to refer to the previous agreements. The counsel pointed out that the various demands made from time to time by the workmen as well as the minutes of the discussion that took place between the parties which ultimately resulted in 454 the various agreements extending over a fairly long period	 win 	clearly show that what was being paid by the Company was production bonus or as an incentive wage. As the same payment was being continued under the agreement of 1962	 the Tribunal was justified in holding that the general bonus that was being paid by the Company over a long number of years was by way of production bonus or as an incentive wage. Mr. Daphtary also referred us to the various provisions contained in the several agreements regarding the duration of the agreements and also to their having binding effect till they were terminated by notice given in accor dance with the terms of the agreement. All this	 according to the counsel	 will clearly show that the intention of the parties was that 	the agreements under which the payments were made were to be throughout the year and also to be continued from year to year. The material on record	 according to the counsel	 will also show that the payments were made quarterly at the express desire and request of the workmen	 but as the payments extended throughout the year and will also continue year to year	 they are in the nature 	of annual payment of bonus. Before we consider the various contentions of the learned 	counsel on both sides	 it is desirable to refer to the material provisions of the Act. All parties are agreed that the additional claim for bonus for the year 1964 was under the provisions of the Act. Section 2(21) defines the expression "Salary or wage". This definition among other things includes dearness allowance also. Section 8 lays down the conditions for eligibility for bonus. Sections 1 0 and 11 deal with the payment of minimum and maximum bonus respectively in the circumstances mentioned therein. Sec tion 17 enables an employer to adjust the amount paid as pooja or customary bonus or interim bonus against the final bonus payable under the Act. Section 32 deals with various classes of employees to whom the Act does not apply. The relevant pro vision with which were are concerned is section 32 (vii) which is as follows : "Section 32. Nothing in this Act shall apply to (a) who have entered before the 29th May	 1965 into any agreement or settlement with their employers for payment of an annual bonus linked with production or productivity in lieu of bonus based on profits; or (b) who have entered or may enter after that date into any agreement or settlement with their employers for payment of such annual bonus in lieu of the bonus payable under this Act	 455 for the period for which such agreement or settlement is in operation;" We are particularly concerned with sub clause (a) of cl. (vii) as the appellants claim is resisted on the basis of the agreement dated August 30	 1962. In order to attract section 32(vii) (a) the Company will have to establish : (1) That there has been an agreement or settlement entered into between the workmen and the Company before May 29	 1965; (2) The said agreement or settlement was one for payment of annual bonus; (3) The said payment of bonus was linked with production or productivity; and (4) The said payment was in lieu of bonus based on profits. In this case there is no controversy that there has been an agreement exhibit A.5 entered into between the parties on August 30	 1962	 which is anterior to May 29	 1965. There is also no controversy that the amount paid under this agreement is characterised as general bonus. The question then arises whether the said payment as general bonus was an annual bonus linked with production or productivity and paid in lieu of bonus based on profits. The nature of production bonus has been discussed by this Court in M/s Titaghur Paper Mills Co. Ltd. vs Its Workmen(1). It has been stated that payment of production bonus is by way of ' an incentive to higher production and is in the nature of an incentive wage. The extra payment depends not on extra profit ' but on production. From this decision it is clear that the principals element in the payment of extra amount is to provide an incentive to production. In The New Maneck Chowk Spinning and Weaving Co. Ltd. Ahmedabad and others vs The Textile Labour Association	 Ahmedabad(2)	 it has been stated that there are four types of bonus which have been evolved under the Industrial Law as laid down by this Court	 namely	 (1) Production bonus or Incentive wage	 (2) Bonus as an implied term of contract between the parties (3) Customary bonus in connection with some festival	 and (4) Profit Bonus which was evolved by the Labour Appellate Tribunal and approved by this Court. Under the Act there is no controversy	 what is payable is the profit bonus. In the case before us	 from the Award it is seen that the Union conceded that the amount paid as general bonus under the agreement was neither customary (1) [1959] Supp. 2 S.C.R. 1012. (2) ; 456 nor profit bonus; nor bonus as an implied term of contract. In the nature of things the Union has not raised the plea that the amount paid under the agreement is a profit bonus. Equally	 the Company could not also take up such a plea as their attempt was to show that it is a payment as production bonus or incentive wages. In Sanghi Jeevaraj Ghewar Chand and others vs Secretary	 Madras Chillies	 Grains Kirana Merchants Workers ' Union and another (1)	 it has been held that where the bar of section 32 (vii) (a) of the Act operates	 the employees in such cases so long as the agreement or settlement is in operation cannot claim bonus on the basis of Full Bench Formula or under the Act. Therefore	 it becomes essential to find out the nature of the payment made under exhibit A.5. That is an agreement entered into between the appellant and the respondent Company on August 30	 1962. The purpose of the agreement is stated to be to promote and improve industrial and economic relationship between the Company and its workmen and to establish and maintain satisfactory working conditions. In Article IV	 among various other .	matters	 the Union	 has acknowledged that it is the exclusive right and function of the Company to maintain among other matters the efficiency. In Article V dealing with lock out and strikes	 the Company	 on the one hand	 has agreed not to declare any lock out so long as the workmen do not commit any breach of the agreement. The Union	 on the other hand	 has also agreed while retaining its right to go on strike	 not to permit its members individually or collectively to curtail or restrict production and certain other matters. Article VI dealing with general bonus is as follows "Article VI General Bonus: "Article VI General Bonus: The Company declares and makes a payment of General Bonus one month after the end of each quarter at the rate of 20% of the total salary and/or wages paid to each workman and employee during the quarter immediately preceding (such salary or wages are exclusive of Dearness Allowance or any other special allowances or rewards granted to him during such period). Such Bonus will be payable to those who have completed six months approved service ending on the last day of the quarter; and to those who have completed less than six months approved service on the last day of the quarter	 the Bonus will be payable at the rate of 10% of their total salary or wages as aforesaid. The Bonus will be available only to those who are in the employ of the (1)[1969] 1 S.C.R. 366. 457 Company on the last date of the quarter and who have given regular and approved service during the quarter	 to which the payment of Bonus is available." Under Article VIII it is provided that the agreement is to be in force until December 31	 1965 and that it shall continue from year to year thereafter unless either party gives notice in writing of its intention to enter into negotiations for the purpose of amendin the agreement. The said Article further provides for the period of notice as well as the starting of negotiations and the agreement continuing to be in force till a new settlement or agreement is arrived at. A mere reading of Article VI relating to general bonus will not by itself throw much light on the character of such payment. But	 it is clear that the payment is to be made at the end of each quarter at the percentage mentioned therein of the total salary or wages which does not include Dearness Allowance. The said Article also provides for the period of service necessary for qualifying to get the higher or lower percentage of bonus as the case may be. The emphasis is also laid on the workmen giving regular and approved service during the quarter to which the payment of bonus is available. Normally	 it is the agreement exhibit A.5	 which has to be looked into for the purpose of ascertaining the rights and liabilities of the employer and employees. That is	 the agreement will have to be looked into for the purpose of ascertaining the nature and character of the general bonus payable under article VI	 provided that clause gives a full and clear indication regarding the character of such payment. But	 a mere reading of Article VI does not give any indication regarding the character of such payment. The other clauses in the agreement also do not throw much light on this aspect. But it is not as if that agreement exhibit A.5 has been entered into between the parties for the first time. The expression "General Bonus" occurs	 as we will show presently	 in certain previous agreements. Under those circumstances	 in our opinion	 in order to properly appreciate the character and nature of the payment that was being made originally and that was continued under Article VI of the agreement of 1962	 it is not only relevant but also necessary to consider the various settlements and agreements that took place between the parties on prior occasions. We are not inclined to agree with the contention of Mr. Mookerjee that the Tribunal has committed a very serious error in law when it tried to interpret the nature of the payment under exhibit A.5 by reference to the previous settlements and discussions that took place between the parties. The Tribunal was perfectly justified in considering those agreements as they	 in our opinion	 458 give a complete and clear picture of the nature of the claims made by the Union	 the stand taken by the Company and the nature of the agreement ultimately arrived at between the parties regarding the payment of the amount in question. Hence we will also refer to the prior agreements as well as the events leading upto those agreements. The earliest agreement is exhibit A. dated May 16	 1946. Under Article V the Company agreed to pay Victory bonus of six weeks pay	 for the employees mentioned therein. Under Article VI	 the Company agreed to pay bonus on production or special bonus equivalent to 10% of pay. It is significant to note that the payment under article VI of this agreement is characterised as a production or special bonus at a fixed percentage on the pay of the employees. On March 6	 1947	 the Union addressed a letter exhibit B to the Company requiring "Production Bonus" to be increased in the manner stated therein. In fact the Union wanted an increased percentage depending upon the salary drawn by the employees. It is to be noted that the Union also understood the payment made under exhibit A. as a production bonus; and under exhibit B it is the production bonus that they wanted to be increased. In view of this demand	 there were discussions between the parties and ultimately they entered into an agreement exhibit C on July 12	 1947. This agreement states that 10% production bonus given under exhibit A is not to be increased. But an extra amount of 5% or 2% was given as an Attendance Bonus. On November 22	 1948	 there was another agreement exhibit A.1 entered into between the parties. Article VI related to ex gratia payment of bonus	 which is as follows: 'Article VI Ex Gratia Payment of bonus The Company declares and makes an ex gratia payment of Bonus one month after the end of each quarter at the rate of 1 0 per cent of the total salary and/or wages paid to each employee during the quarter immediately preceding (such salary or wages are exclusive of dearness allowance or any other special allowances or attendance bonus or rewards granted to him during the said period); such bonus will be payable only to those employees who have completed six months ' approved service ending on the last day of the quarter; and to those employees who have completed less than six months ' approved service on the last day of the quarter the exgratia Bonus will be payable at the rate of 5 % of their total salary or wages as aforesaid. The ex gratia Bonus	 will be available only to those employees who are in the employ of the Company on the date fixed for payment 459 and who have given regular and approved service during the quarter to	 Which the ex gratia payments of Bonus is available. ' It will be noted that while in the agreements Exs. A and C	 what was characterised as production bonus	 has been changed in exhibit A. 1 as ex gratia payment of bonus. Article VIII provided for the. agreement being in force till December 31	 1950 and to continue year to year unless either party gives notice in writing of its intention to enter into negotiations for the purpose of amending the agreement. On May	 15	 1951	 the Union made a representation for modi fying the agreement exhibit A. 1. In respect of this demand on October 3	 1951	 agreed minutes of discussion and agreement between the parties were recorded in exhibit D. From exhibit D it is seen that the Union had accepted the position that the approximate living wage has been attaired in this Company and therefore the bonus has to	 be	 paid as an incentive to greater efficiency	 in production as. well as towards labour 's contribution to the prosperity of the Company. In view of this the Union	 represented that the	 bonus that is being paid should not be regarded as ex gratia payment. Hence the Company was requested to delete the expression "ex gratia" and to substitute	 the word "general". The Union further suggested that as the payment of bonus on the basis of earned salary is a sufficient incentive for attendance	 the attendance bonus	 which was being paid at a flat rate discontinued and that a general bonus is to be paid at a flat rate of 15% every quarter to all the employees. This representation was accepted by	 the Company and exhibit D. shows that it was agreed between the parties that the attendance bonus was to be discontinued and that the term "ex gratia" was to be substituted by the word "general". It was also greed that the rate should be increased to 15% and 7 1/2 % respectively. The suggestion of the Union for payment of the amount every quarter was also agreed to by the parties. It was also agreed that the arrangements entered into between the parties are to continue till December 31	 1953. From exhibit D. it is clear that the Union itself has required the payment of bonus to be made " as an incentive to greater efficiency in production "and the workmen wanted the expression "ex gratia" to be substituted by the word"general". The Union accepted that approximiate living wage is being earned by the employees of this Company. Further the Union wanted teh amount to be paid at a flat fixed rate every quarter. It is also to be noted from Ex.D. that the changes agreed to between the parties were to take effect from the first quarter of 1952. On the basis of the arrangement recorded in exhibit D. the parties entered into a formal agreement exhibit A.2 on November 22	 1951. This is called Collective Agree L1286SupCI/72 460 ment as finally amended by the settlement of October 3	 1951	 evidenced by exhibit D. Article I dealing with the purpose of the agreement states that it was with a view to promote and improve industrial and economic relationship between the Company and its employees and to establish and maintain satisfactory working conditions. Article VI dealing with the general bonus is as follows : " Article VI General Bonus The Company declares and makes a payment of General Bonus one month after the end of each quarter at the rate of 15 per cent of the total salary and/or wages paid to each employee during the quarter immediately preceding (such salary or wages are exclusive of Dearness Allowance or any other special allowance or rewards granted to him during such period); such bonus will be payable only to those employees who have completed six months ' approved service ending on the last day of the quarter; and to those employees who have completed less than six months ' approved service on the last day of the quarter the Bonus will be payable at the rate of 7 1/2% of their total salary or wages as aforesaid. The Bonus will be available only to those employees who are in the employ of the Company on the last date of the quarter and who have given regular and approved service during the quarter to Which the payment of Bonus is available. " It will be noted that this article is in substitution of the original Article VI in the 1948 agreement exhibit A.1. What was characterised as ex gratia payment of bonus in exhibit A.1 was designated as general bonus in exhibit It must be noted that it was for the first time that the expression "general bonus" has found a place in the agreement between the parties. This change was effected due to the representation made by the Union and accepted by both the parties as recorded in the minutes exhibit The rate has been increased to 15% and 7 1/2% respectively depending upon the service of the employee. This rate is on the basic wages; and dearness allowance has been excluded for purposes of calculation. Attendance bonus was abolished and the rate in Article VI shows that it has combined the old production bonus as well as the attendance bonus. The payment is also to be made every quarter as required by the Union. Article VIII provided that the agreement shall be in force upto December 31	 1953 and was to continue from year to year thereafter unless either party gives notice in writing of its intention to enter into negotiations for the purpose of amending the agreement. 461 On December 28	 1953 the Union made a representation for effecting certain modification in the agreement exhibit A.2. This was followed by the proposals contained in exhibit B. 3 on March II	 1954. Paragraph 3 of exhibit B.3 relates to bonus. After referring to the existing payment of general bonus at the rate mentioned in exhibit A.2	 the Union made a request to the Company to revise the rate of bonus by including dearness allowance also in the wages or salaries for purposes of calculation of bonus	 the reason being "the necessity of giving incentive to the employees and the rate at which bonus is paid to employees of 'many other comparable concerns. " There was also a demand for pooja or festival bonus. Ultimately	 the demand with regard to bonus was that : (a) the general bonus paid quarterly at the end of each quarter of the year should be increased to 20% and 10% depending upon the length of service of the employee and the payment at the said percentage should be on a calculation of both the basic wages and dearness allowance paid to an employee during the quarter; and (2) the workmen should be paid pooja bonus equal to three months wages including dearness allowance besides the general bonus. There was a supplementary claim made on behalf of the Union on March 15	 1954 under exhibit B.4	 that the payment to be made under exhibit B.3	 should have retrospective effect from January 1	 1954. Three points emerge from this demand of the Union : (1) Increase in the rate of general bonus and percentage to be worked out on wages including dearness allowance; (2) A claim for payment of pooja or festival bonus; and (3) The payments of both (1) and (2) to take effect from January 1	 1954. But the significant point to be noted is that in exhibit B. 3 the reason given by the Union itself for claiming general bonus at an increased rate and for working out the percentage of wages including dearness allowance was "the necessity for giving incentive to the employe . " These demands of the Union were discussed and agreed minutes of discussion and agreement were recorded in exhibit D. 1 dated February 18	 1955. It is seen that there were as many as 45 meetings between the representatives of the Union and the Company beginning from April 9	 shows that the demands in letters dated December 28	 1953	 March 11	 1954 and March 15	 1954 were discussed thread bare between the parties. The minutes show that the Company was not willing to accede in full to the increased rates claimed by the Union regarding general bonus: nor was it inclined to take into account dearness allowance for the purpose of calculation of bonus. But the Company was prepared to show some consideration by merging a part of the dearness allowance in the basic wages as that will result in a slightly higher amount being received as general bonus by the workmen. The claim for pooja or festival bonus was not accepted by the Company. Both parties ultimately agreed that the gene 462 ral bonus will be paid at 17 1/2% instead of the original 15% as per exhibit A.2. The minutes further show that all demands made by the Union have be en fully settled by increasing the percentage of general bonus. The tentative agreement recorded in exhibit D.1 was the subject of a collective agreement between the parties under exhibit A.3 dated February 18	 1955. Article VI deals with general bonus. Except for the difference in the rate of 17 1/2 % and 8.7 5 % on the	 basic wages excluding dearness allowance	 the provision regarding payment of general bonus under this Article was similar to those contained in Article VI of exhibit A.2 of 195 1. Article Vill provided that the agreement is to be	 in force till December 3 1	 1957 and that it was to continue from year to year thereafter unless either party has	 given notice in the manner provided therein. On December 24	 1957 the Union sent a letter exhibit B.5 to the Company requiring the general bonus. to be paid at 50% and 25% respectively in place of the present rate of 17 1/2 % and 8.75%. The demand was also to calculate this rate on salaries including the dearness allowance. A further request was made that half of the bonus as per the demand be paid "in four quarters in a year as at present and the remaining half at the time of pooja every year". This again led to the parties discussing the demands and the minutes of discussion and conclusions arrived at	 by the parties by agreement are recorded in exhibit D.2 dated October 6	 1958. The minutes disclose that the demands of the Union were carefully considered by the Company. The Chairman of the Company drew the attention of the	 Union to the agreed minutes of settlement exhibit D and pointed out "that bonus was being paid as an incentive to greater efficiency in. 'production. . and suggested that "bonus payment be linked with the generally accepted formula and be no longer paid on percentage basis. But the Union did riot accept the suggestion of the Chairman and stated that "as a matter of security they would like the continuation of the same to be paid on a fixed percentage basis. " After further discussion	 the Chairman agreed to a token increase in the rate of bonus. It was agreed between both the parties that the payment of general bonus will be increased from 171% to 18 21% on the wages excluding dearness allowance. The conclusions so arrived at were incorporated in the agreement exhibit A.4 on October 6	 1948. This again is styled as a collective agreement. Article VI relating to general bonus is substantially the same as article VI in exhibit A.5 excepting that the rate was 18 1/2% and 9.25% depending upon the service of the workman. The percentage was to be calculated only on the total salary excluding dearness allowance and the general bonus was to be paid at the end of every quarter. Article VIII provides that the claim was to be in force till December 31	 463 1965 and that it was to continue from year to year unless a notice was given by either party in the manner provided therein. This takes us to the agreement under consideration exhibit A.5 dated August 30	 1962. This is the seventh agreement in the series. We have in the earlier part of the judgment referred to Articles VI and VIII. Article VI deals with general bonus and it was to be paid at 20% and 10% respectively on the basic wages excluding dearness allowance. It was to be paid at the end of each quarter. It will be seen that the rates ate slightly higher than those provided in the previous agreement exhibit A.4 of 1958. We have very exhaustively dealt with the various demands made by the workmen	 the minutes recording the discussion that took place between the patties regarding the demands	 the conclusions arrived at therein as well as the final agreements entered into on different dates between the parties	 as they furnish the background	 so to say	 for the agreement under consideration exhibit A.5. It will be seen that originally in 1946 the payment was made as production or special bonus. Specific demand was made by the Union on March 6	 1947 to increase "production bonus". The Company did not agree to this request. On the other hand	 exhibit C.	 the agreement	 clearly shows that there would be no increase in production bonus. But an additional amount was given as attendance bonus. In 1948 what was originally characterised as production bonus was termed "ex gratia" payment of bonus. The Union specifically desired in 1951 to substitute "exgratia bonus" by "general bonus" and to abolish attendance bonus. The demand also was for general bonus to be paid at a flat rate every quarter. For the first time the expression "general bonus" occurs in the demand made by the Union on May 15	 1951 and in the agreed minutes of October 3	 1951. The same was incorporated in the final agreement of November 22	 1951. The Union made a demand on March 11	 1954 for increase in the rate of general bonus so as to provide an incentive to the employees. This was accepted and embodied final in the agreement dated February 18	 1955. In exhibit B.5	 the Union made a specific demand for further increase of the rate of general bonus and wanted half the amount to be paid quarterly as at present and the balance at the time of pooja. Though	 the minutes of the discussion in respect of this demand shows that the Chairman. of the Company wanted to alter what was given as incentive to greater efficiency in production to one on profit basis	 the Union preferred the payment to be continued as was being done on a fixed percentage basis. The pattern of bonus paid sometimes called production bonus	 later on called ex gratia payment	 but from 1951 called as general bonus	 was being paid quarterly at a 'Particular percentage base on the salary excluding dearness allowance. Having this background in mind	 it is clear that what was being paid under article VI 464 of exhibit A.5 was a payment linked with production or productivity. The principal emphasis is that the amount is being paid as an 	incentive to production and therefore it is paid as production bonus or as a wage incentive. That it is an incentive payment in order to secure greater efficiency in production is clear from Exs. D	 B.3	 and D.2. We have already referred to the contents of these exhibits in great detail. Even the workmen in exhibit B.3 required the rate of general bonus to be increased in view of the necessity of giving incentive to the employees. But a more important point emerges from the minutes of discussion recorded on October 6	 1958 in exhibit D.2. The Chairman of the Company emphasised that what was being paid as general bonus was as an incentive to greater efficiency in production. The Chairman specifically wanted this method of payment to be changed and suggested that the bonus payment be linked with the generally accepted formula	 namely	 of profit bonus and that the payment on a fixed percentage be abolished. But this suggestion to alter the nature of the payment from a fixed percentage as a production bonus for providing an incentive to greater efficiency in production was not accepted by the Union	 which wanted the fixed percentage basis to be continued. That is	 the Union was not prepared to receive bonus on the basis of profits	 but wanted to continue the existing arrangement of payment at a fixed percentage as an incentive to efficiency in production. That is	 the Union wanted the character of the payment as production bonus being continued. Therefore	 these circumstances clearly lead to the conclusion that the payment that was being made and continued in the agreement exhibit A.5 was payment of bonus linked with production or productivity. It is also clear that the said payment was made in lieu of bonus based on profits because the Union itself did not agree to the suggestion of the Chairman as contained in exhibit D.2 to alter the character of payment to one of profit sharing bonus. Therefore	 this also shows that the payment under exhibit A.5 was in lieu of bonus based on profits. The expressions used in section 32 (vii) (a) are "linked with production or productivity" and that test is satisfied in respect of the payment made under exhibit A.5. It is not the case of the Union that the character of payment which was designated as an incentive to greater efficiency in production even as early as 1951 (vide exhibit D) has been altered either in the subsequent agreements or in the agreement exhibit A.5. If so	 it follows that the payment of general bonus in exhibit A.5 retains the same character as a payment by way of an incentive to greater efficiency in production. As the minutes of the discussion that took place between the parties have been recorded then and there	 they are items of evidence which are more valuable and useful than the oral evidence adduced by the parties. For instance	 P.W. 1	 Secretary of the Union	 has deposed that the payment in exhibit A.5 is not linked with 465 production. On the other hand	 the Labour Officer of the Company	 as D.W. I has stated that the said payment is linked with production. This type of evidence does not lead us any where. That is why	 we have placed more emphasis and reliance on the documentary evidence adduced by the parties	 more especially when there is no controversy that the record of the meetings do not represent the actual facts. Then the question is whether the bonus paid is an annual bonus	 which is another requirement of section 32 (vii) (a) of the Act. That bonus has been paid at the end of every quarter at any rate from 1948	 is clear from the various settlements and agreements	 referred to earlier. That the Union itself required that bonus should be continued to be paid quarterly	 is clear from the letters written by the Union	 particularly exhibit B.5 dated December 24	 1957. We have already referred to the various agreements which no doubt prescribe the normal duration of the period of the agreement	 which extends to over a year. There is also a further provision to the effect that even after the date of expiry mentioned therein	 the agreement will continue to be. in force till a notice is given in the manner provided for in the agreement. Therefore	 it will be seen that it is not as if that bonus is paid for one quarter and does not enure for a succeeding quarter. On the other hand	 the amounts payable are not restricted to one particular quarter and the intention is made clear in the agreement that it has to operate throughout the year and also continue from year to year. It is not possible to accept the contention of Mr. Mookerjee that it is only when a payment is made at the end of the year	 it can be considered to be an annual bonus. The essential test to be satisfied is that the payment should enure throughout the year and it should also be continued from year to year. As observed by Lord Maugham in Moss ' Empires	 Ltd. vs Inland Revenue Commissioners(") the expression "annual" must be taken to have the quality of being recurrent or being capable of recurrence. Adopting this test	 the payments in the case before us were to continue the whole of the year and also were to be paid from year to year not only during the period of agreement but also for the succeeding year till the required notice was given under the agreement Even then there is a provision in the agreement to the effect that the agreement will continue to have force notwithstanding the notice till a fresh agreement or settlement is entered into. Therefore it is clear that the payment of general bonus is "annual bonus" as contemplated by section 32 (vii) (a) of the Act. The Court of Appeal in Smith vs Smith (2 ) had to consider whether a payment to be made weekly during the life time of a person was an "annual payment". It was held as follows (1) (2) [1923] Probate Division 191. 466 "It is no doubt payable weekly	 but that fact does not prevent it from being an annual payment if the weekly payments may extend beyond a year. " The position	 as pointed opt by us earlier	 in the case before	 us	 is also the same. It follows from the discussion above that the general bonus paid under Article VI of the agreement dated August 30	 is a payment of annual bonus linked with production or productivity in lieu of bonus based on profits. It further follows that as the agreement has been entered into before May 29	 1965	 the employees cannot claim any additional bonus under the Act for the period for which the agreement is in operation. It is the case of all parties that the agreement exhibit A.5 at the relevant time was in operation. If so	 it follows that the view of the Tribunal that section 32(vii) (a) of the Act is a bar to claim any additional bonus under the Act is correct. In the result	 the award of the Industrial Tribunal is confirmed and this appeal dismissed. There will be no order as to costs.

A dispute arose between the respondent company and the appellants workmen as regards payment of profit bonus under the . The company	 and the appellants	 represented by its Union had been entering into various agreements from time to time	 the last being the agreement on August 30	 1962 (	Ex. As per exhibit A 5	 the respondent paid bonus for the year 1964 at the rates mentioned therein. The appellants demanded that they should be paid the profit bonus as per the Act in addition to what has been paid under the agreement	 exhibit A 5. The Company pleaded section 32(vii) (a) of the Bonus Act as a bar to further bonus. On a reference to the Industrial Tribunal	 it was held that in view of the general bonus paid under agreement exhibit A 5	 it was an annual bonus	 though paid quarterly	 and it was linked with production or productivity and that it was paid in lieu of bonus based on profits. Therefore	 the workmen are not entitled to claim bonus for the year 1964 under the Act. On appeal to this Court	 it was contended that payments. under the agreement	 exhibit A 5	 was made quarterly and they do not have that character of an annual bonus. There is no material or record to show that the company paid the amount in lieu of bonus based on profits. The amount paid under the agreement was only an ex gratia payment and not a profit bonus under the Act. The respondent	 however	 contended that in order to decide the character of the general bonus paid under the agreement of 1962	 previous agreement must be referred to	 which would clearly show that what was being paid by the company was production bonus or as an incentive wage and not an ex gratia payment. Dismissing the appeal	 HELD : The general_ bonus paid under article VI or the agreement dated August	 30	 	 was a payment of annual bonus based on profits. Although Article VI of exhibit A 5 does not throw much light as to the nature and character of the general bonus payable under it	 a reference back to previous settlements and discussions between the parties will show that the pattern of bonus paid to the workers weresometimes called production bonus	 later on called ex gratia payment. 	 but from 1951 called as general bonus	 which was paid quarterly	 at the request of the workers	 at a particular percentage based on salary excluding dearness allowance	 having this background in mind	 it is clear that what was being paid under article VI of exhibit A 5 was a payment linked with production or productivity. The principal emphasis was that the amount	 was being paid as an incentive to production and therefore	 it was paid as production bonus as a wage incentive. Further	 it was an annual bonus paid from year to year not only during the period of agreement but also for the succeeding year till the required notice was given under the agreement. Even then	 the agreement was to continue to have 451 force notwithstanding the notice till a fresh agreement entered into. Therefore	 it is clear that the payment of general bonus paid quarterly was "annual bonus" as contemplated by section 32(vii)(a) of the Act. [464 A 465 G] Smith vs Smith	 	 and Moss ' Empires Ltd. vs Inland Revenue Commissioners	 followed. Under the circumstances ' workers could claim not any additional bonus under the Art for the period for which the agreement was in operation and section 32 (vii) (a) of the Act was a bar to their claim.
