Summarize the following court judgment. ivil Appeal No. 850 of 1966. 870 Appeal by special leave from the judgment and decree dated March 5	 1965 of the Bombay High Court in First Appeal No. of 1963. section Sorabli	 Bhuvanesh Kumari and J.B. Dadachanji	 for the appellant. The respondent did not appear. The Judgment of the Court was delivered by Ramaswami	 J. This appeal is brought by special leave fro.m the judgment of the. Bombay High Court dated March 5	 1965 in Appeal No. 415 of 1963. Shalkh Hassan Ibrahim (hereinafter referred to as the missing seaman) was employed as a deck hand	 a seaman of category II on the ship sections "Dwarka" which is owned by the British India Steam Navigation Company Limited of which the appellant is the Agent. The Medical Log Book of the shop shows that on December 13	 1961 the missing seaman complained of pain in the chest and was	 therefore	 examined	 but nothing abnormal was detected clinically. The Medical Officer on board the ship prescribed some tablets for the missing seaman and he reported fit for work on the next day. On December 15	 1961	 however	 he complained of insomnia and pain in the chest for which the Medical Officer prescribed sedative tablets. The official Log Book of the ship shows that on December 16	 1961 when the ship was in the Persian Gulf the missing seaman was seen near the bridge of the ship at about 2.30 a.m. He was sent back but at 3 a.m. he was seen on the Tween Deck when he told a seaman on duty that he was going to bed. At 6.15 a.m. he was found missing and a search was undertaken. At 7.35 a.m. a radio message was sent by the Master of the ship. saying: "One seaman missing between Khoramshahr and Ashar STOP May be in river STOP All ships please keep look out". The ship arrived alongside Ashar Jetty at 8 a.m. when a representative of Messrs Gray	 Mackenzie & Co. Ltd.	 who are the agents for the British India Steanm Navigation Co. Ltd.	 in the Persian Gulf was informed that the said seaman was missing. The representative in turn passed on the information to the local police and the Port authorities. The last entry in the log book shows that at 4 p.m. an inquiry was held on board the ship by the local police and the British Consul General. On a suggestion made by the latter	 the personal effects of the missing seaman were checked and sealed by the Consulate authorities for being deposited with the Shipping Master	 Bombay. On February 20	 1962 the respondent filed an application under section 3 of the Workmen 's Compensation Act (Central Act 18 of 1923) (hereinafter referred to as the Act) claiming compensation of Rs. 4	810/ for the death of his son	 the missing seaman	 which 871 according to him	 occurred on account of a personal injury caused by an accident arising out of and in the course of his employment. The appellant put in a written statement on April 26	 1962 and disputed the respondent 's claim on the ground that there was nothing to show that the seaman was in fact dead	 that the death	 if any	 was not caused in the course of the employment	 that in any event the death could not be said to have been caused by an accident which arose out of employment and that the probabilities were more consistent with a suicidal death than with an accidental death. But the appellant did not lead oral evidence at the trial of the claim. The Additional Commissioner	 however	 inspected the ship on January 23	 1963. By his judgment dated February 6	 1963 held that there was no evidence to show that the seaman was dead and there was in any event no evidence to justify the inference that the death of the missing seaman was caused by an accident which arose out of employment. In the course of his judgment the Additional Commissioner observed as follows: "Now in the present case what is the evidence before me ? It is argued on behalf of applicant that I must presume that the man fell down accidentally. From which place did he fall down ? How did he fall down ? At what time he fell down ? Why was he at the time at the place from which he fell down ? All these questions	 it is impossible to answer. Am I to decide them in favour of the applicant simply because his 'missing ' occurs in the course of his employment ? In my opinion there is absolutely no material before me to come to a conclusion and connect the man 's disappearance with an accident. There are too many missing links. Evidence does not show that it was a stormy night. I had visited the ship	 seen the position of the Bridge and deck and there was a bulwark more than 31/2 feet. The man was not on duty. Nobody saw him at the so called place of accident. In these circumstances I am unable to draw any presumption or conclusion that the man is dead or that his death was due to an accident 'arising out of his employment. Such a conclusion	 presumption or inference would be only speculative and unwarranted by any principle of judicial assessment of evidence or permissible presumptions. " The Additional Commissioner	 however	 negatived the contention of appellant that the death	 if any	 was caused by the seaman 's voluntary act. The respondent preferred an appeal on April 17	 1963 to the High Court from the judgment of the Additional Commissioner dated February 6	 1963. At the hearing of the appeal it was agreed that the appellant would pay to the 872 respondent a sum of Rs. 2	000/ as and by way of compensation in any event and irrespective of the result of the appeal. The respondent agreed to accept the sum of Rs. 2	000/ . But in view of the serious and important nature of the issues. the High Court proceeded to decide the questions of law arising in the appeal. By his judgment dated March 5	 1965 Chandrachud J.	 allowed the appeal and reversed the judgment of the Additional Commissioner and granted the application for compensation. The view taken by Chandrachud J.	 was that the death of the seaman in this case must be held to have occurred on account of an accident which arose out of his employment. The principal question that arises in this appeal is whether the accident arose in the course of employment and whether it arose out of employment within the meaning of 'section 3 of the Act which states: "(1) If personal injury is caused to a workman by accident arising out of and in the course of his employment	 his employer shall be liable to pay compensation in accordance with the provisions of this Chapter: Provided that the employer shall not be so liable (a) in respect of any injury which does not result in the total or partial disablement of the workman for a period exceeding three days; (b) in respect of any injury	 not resulting in death	 caused by an accident which is directly attributable (i) the workman having been at the time thereof under the. influence of drink or drugs	 or (ii) the willful disobedience of the workman to an order expressly given	 or to a rule expressly framed	 for the purpose of securing the safety of workmen	 or (iii) the willful removal or disregard by the workman of any safety guard or other device which he knew to have been provided for the purpose of securing the safety of workmen. To come within the Act the injury by accident must arise both out of and in the course. of employment. The words "in the course of the employment" mean "in the course of the work which the workman is employed to do and which is incidental to it. " The words "arising out of employment" are understood to mean that "during the course. of the employment	 injury has resulted from some risk incidental to the duties of the service	 which unless engaged in the duty owing to the master	 it is reasonable 873 to believe the workman would not otherwise have suffered." In other words there must be a causal relationship between the accident and the employment. The expression "arising out of employment" is again not confined to the mere nature of the employment. The expression applies to employment as such to its nature	 its conditions	 its obligations and its incidents. If by reason of any of these factors the workman is brought within the scene of special danger the injury would be one which arises 'out of employment '. To put it differently if the accident had occurred on account of a risk which is an incident of the employment	 the claim for compensation must succeed	 unless of course the workman has exposed himself to an added peril by his own imprudent act. In Lancashire and Yorkshire Railway Co. vs Highley(1) Lord Sumner laid down the following test for determining whether an accident "arose out of the employment": "There is	 however	 in my opinion	 one test which is always at any rate applicable	 because it arises upon the very words of the statute	 and it is generally of some real assistance. It is this: Was it part of the injured person 's employment to hazard	 to suffer	 or to do that which caused his injury ? If yea	 the accident arose out of his employment. If nay	 it did not	 because	 what it was not part of the employment to hazard	 to suffer	 or to do	 cannot well be the cause of an accident arising out of the employment. To ask if the cause of the was within the sphere of the employment	 or was one of the ordinary risks of the employment	 or reasonably incidental to the employment	 or conversely	 was an added peril and outside the sphere of the employment	 are all different ways of asking whether it was a part of his. employment	 that the workman should have acted as he was. acting or should have been in the position in which he was	 whereby in the course of that employment he sustained injury. " In the case of death caused by accident the burden of proof rests upon the workman to prove that the accident arose out of employment as well as in the course of employment. But this does not mean that a workman who comes to court for relief must necessarily prove: it by direct evidence. Although the onus of proving that the injury by accident arose both out of and in the course of employment rests upon the applicant these essentials may be inferred when the facts proved justify the inference. On the one hand the Commissioner must not surmise	 conjecture or guess; on the other hand	 he may draw an inference from the proved facts so long as it is a legitimate inference. It is of course impossible to. lay down any rule as to the degree of (1) 874 proof which is sufficient to justify an inference being drawn	 but ' the evidence must be such as would induce a reasonable man to draw it. Lord Birkenhead L.C. in Lancaster vs Blackwell Colliery Co. Ltd.	 ( 1 ) observed: "If the facts which are proved give rise to conflicting inferences of equal degrees of probability so that the choice between them is a mere matter of conjecture	 then	 of course	 the applicant fails to prove his case because it is plain that the onus in these matters is upon the applicant. But where the known facts are not equally consistent	 where there is ground for comparing and balancing probabilities as to their respective value	 and where a reasonable man might hold that the more probable conclusion is that for which the applicant contends	 then the Arbitrator is justified in drawing an inference in his favour." In cases of the unexplained drowning of seamen	 the question has often arisen as to whether or not there was evidence to justify the inference drawn by the Arbitrator that the seaman met his death through accident arising out of and in the course of his employment. The question was considered by the House of Lords in Kerr or Lendrum vs Ayr Steam Shipping Co. Ltd.(a) in which the steward of a ship	 which was in harbour	 was lying in his bunk	 when he was told by the captain to prepare tea for the crew. He was shortly afterwards missing	 and the next day his dead body	 dressed ' in his underclothes only	 was found in the sea near the ship. The bulwarks were 3 feet 5 inches above the deck. The steward was a sober man	 but was subject to nausea. Murder and suicide were negatived by the Arbitrator	 who drew the inference that the deceased left his bunk	 went on deck	 and accidentally fell overboard and was drowned. He accordingly held that the accident arose out of and in the course of his employment as steward. The Court of Sessions reversed his decision on the ground that there was no evidence to support it. The House of Lords (Earl Lorebum	 Lord Shaw of Dunfermline and Lord Parmoor	 Lord Dunedin and Lord Atkinson dissenting)	 however	 upheld the decision of the Arbitrator on the ground that	 although upon the evidence it was open to him to have taken a different view	 his conclusion was such as a reasonable man could reach. "I should state my main proposition thus	 said Lord Shaw of Dunfermline, that we in this House are not considering whether we would have come to the same conclusion upon the facts stated as that at which the (1) 1918 W.C. Rep. 345. (2) [1195] A.C. 217. 875 learned Arbitrator has arrived. Our duty is a very different	 a strikingly different one. It is to consider whether the Arbitrator appointed to be the judge of the facts	 and having the advantage of hearing and seeing the witnesses	 has come to a conclusion which could not have been reached by a reasonable man." Lord Parmoor said: I wish to express no opinion either way on the reasonableness of the finding in itself as long as it is possible finding for a reasonable man	 whilst Earl Loreburn observed that they should regard these awards in a very broad way and constantly remember that they were not the tribunal to decide. In the case of unexplained drowning of seamen	 the English Court of Appeal have drawn some very fine distinctions. In Bender vs Owners of S.S. "Zent"(1) the chief cook on board a steamship fell overboard and was drowned while the ship was on the high seas. He was seen at 5.25 a.m. looking over the side; 5.30 a.m. was his usual time for turning out; and he was last seen at 5.35 a.m. going aft. The weather was line at the time	 it was daylight	 the ship was steady	 and there was no suggestion that the duties of the deceased would lead him into any danger. There was a 4 ft. rail and bulwark all round the ship and there was no evidence to show how the deceased had fallen overboard. The County Court Judge drew the inference that his death was caused by an accident arising out of and in the course of his employment	 but the Court of Appeal held that there was no evidence to warrant such inference	 Cozens Hardy	 M.R. pointing out that	 although it was conceivable that he might have been engaged on some ship 's work	 it was equally conceivable that he had been larking or had committed suicide. Bender 's case(1) was followed in Marshall vs Owners of S.S. "Wild Rose(2) where an engineer came on board his vessel	 which was laying in a harbour basin	 shortly after 10 p.m. Steam had to be got up by midnight. He went below and took off his clothes	 except his trousers	 shirt and socks. It was a very hot night	 and he subsequently came out of his berth	 saying that he was going on deck for a breath of fresh air. Next morning his dead body was found at the side of the vessel	 just under the place where the men usually sat. It was held by the Court of Appeal	 reversing the County Court Judge	 that there was no legitimate ground for drawing the inference that the engineer died from an accident 	arising out of his employment. Farwell	 L.J. said: "If an ordinary sailor is a member of the watch and is on duty during the night and disappears	 the in ference might fairly be drawn that he died from an acci (1) (2) [1909] 2 K.B. 46. 876 dent arising out of his employment. But if	 on the other hand	 he was not a member of the watch	 and was down below and came up on deck when he was not required for the purpose of any duty to be performed on deck	 and disappeared without our knowing anything else	 it seems to me that there is absolutely nothing from which any Court could draw the inference that he died from an accident arising out of his employment." This decision was upheld by the House of Lords by a majority of one (Lord Loreburn	 L.C. and Lord James of Hereford dissenting) Lord Shaw of Dunfermline saying: "The facts in every case may leave here and there a hiatus which only inference can fill. But in the present case	 my Lords.	 the name of inference may be apt to be given to what is pure conjecture. What did the sailor Marshall do when he left his berth and went on deck ? Nobody knows. All is conjecture. Did he jump overboard	 walk overboard	 or fall overboard ? One can infer nothing	 all is conjecture. Was there an accident at all	 or how and why did the deceased unhappily meet his fate ?. There can be	 in my view	 nothing dignified with the name of an inference on this subject	 but again only conjecture. " But in Rice vs Owner of Ship "Swansea Vale" (1) where the deceased was a "seaman" in the strict sense of the term that is to say	 one whose duty it was to work on deck and not a ship is cook	 'as in Bender 's case	 nor an engineer as in Marshall 's case	 a different conclusion was arrived at. In that case the chief officer of a vessel	 who was on duty on deck	 disappeared from the ship in broad daylight. No. one saw him fall overboard	 but there was evidence that not long before he had complained of headache and giddiness. It was held	 (Buckley	 L.J. dissenting) that there was evidence from which the Court might infer that he fell overboard from an accident arising out of and in the course of his employment. The cases of Bender and Marshall were distinguished	 as in those cases the men 's duties were below deck and at the time they lost their lives they had certainly no duties which called them on the deck. In the House of Lords	 Lord Lorebum	 L.C. having discussed the various things that might have happened	 said: "The other alternatives were suicide or murder. If you weigh the probabilities one way or the other	 the probabilities are distinctly greater that this man perished through an accident arising out of and in the course of his employment. " (1) 877 In Gatton vs Limerick Steamship Co.(1) a night watchman on board a vessel	 whose hours of duty were from 7 p.m. to 7 a.m. when he awoke the crew	 was last seen on board at 6 a.m. but on that morning he did not awake the crew. His cap was. found on the deck	 and his body was found in the harbour some months afterwards. The County Judge held that it was not proved that the accident arose "out of ' his employment and the Court of Appeal on the ground that this was a finding of fact with evidence to support it	 refused to interfere. Holmes	 L.J.	 however	 stated that the County Court Judge might have arrived at a different conclusion of fact	 whilst Cherry	 L.J.	 said that	 if he had been the Arbitrator	 he would have found that the deceased had met with his death by accident arising out of and in the course ' of his employment. In another similar case Rourke vs Mold & Co. (2) a seaman disappeared during his spell of duty at the wheel in the wheel house in the centre of the flying deck and was not afterwards seen. The night was rough	 the sea choppy but the vessel was steady. The flying deck was. protected by a rail. There was no evidence as to how the man met his death and in spite of the presumption against suicide the County Court Judge was unable to draw the inference that the death was due to accident. It was held by the Court of Appeal that in the circumstances the conclusion of the County Court Judge was right. At p. 321 of the Report O 'Brien	 L.C. said: "In this case we cannot interfere with the finding of the County Court Judge. The post of duty of the deceased was at the wheel and to steer a certain course until ordered to change it	 but nobody knows how the man disappeared	 or how he came to leave his post. It is conceivable that he may have fallen overboard in such circumstances as to entitle his widow to claim compensation on the ground that his death was due to an accident arising out of and in the course of the employment; but the onus of proof is on the applicant. That onus is not discharged by asserting that we must assume that the deceased was at his allotted employment when he fell overboard	 although the natural inference would be that he was not	 and that we should then draw the conclusion that the accident arose out of and in the course of the employment. " In Simpson V.L.M. & section Railway Co.(3) Lord Tomlin reviewed all the previous authorities and stated the principle as follows: " . from these passages to which I have referred I think this rule may be deduced for application to (1) (2) [1917] 2 It. Rep. 318 at 321. (3) 878 that class of case which may be called unexplained accident cases namely	 that where me evidence establishes that in the course of his employment the workman properly in a place to which some risk particular thereto attaches and an accident occurs capable of explanation solely by reference to that risk	 it is legitimate	 notwithstanding the absence of evidence as to the immediate circumstances of the accident	 to attribute the accident to that risk	 and to hold that the accident arose out of the employment; but the inference as to the origin of the accident may be displaced by evidence tending to show that the accident was due to some action of the workman outside the scope of the employment. Such a rule so stated seems to me to be consistent with all the previous decisions of your Lordships ' House including Marshall vs Owners of S.S. Wild Rose(1) where there was some evidence from Which it could be inferred that the seaman who fell overboard had by action of his own outside his employment added a peril to his position. " In the same case Lord Thankerton expressed the principle in similar language. Lord Thankerton said at p. 371 of the Report: " . the principle to be applied in such cases is that if the accident is shown to have happened while the deceased was in the course of his employment and at a place where he was discharging the duties of his employment	 and the accident is capable of being attributed to a risk which is ordinarily inherent in the discharge of such duties	 the arbitrator is entitled to infer	 in the absence of any evidence tending to an opposite conclusion	 that the accident arose out of the employment." In a later case in the House of Lords	 Rosen vs S.S. "Querous" :(Owners) Lord Buckmaster explained that in that passage in Lord Thankerton 's speech in Simpson 's case(2) the place referred to was not the exact spot at which the accident may have occurred	 but meant	 in that case the train on which the workman was traveling and in the later case in the House of Lords the ship on which the workman was employed. The same principle applies in Indian law as the language of section 3 of the Indian Act is identical with section 1 of the English Workmen 's Compensation Act of 1925. What are the facts found in the present case ? Shaikh Hassan Ibrahim was employed as a deck hand	 a seaman of category II on the ship. The medical log book of the ship showed that on (1) (2) 879 December 13	 1961 Shaikh Hassan complained of pain in the chest and was	 therefore	 examined	 but nothing abnormal was detected clinically. The Medical Officer on board the ship prescribed some tablets for Shaikh Hassan and he reported fit for work on the next day. On the 15th	 however	 he complained of insomnia and pain in the chest for which the Medical Officer prescribed sedative tablets. The official log book of the ship shows that on the 16th when the ship was in the Persian Gulf	 Shaikh Hassan was seen near the bridge of the ship at about 2.30 a.m. He was sent back but at 3 a.m. he was seen on the Tween Deck when he told a seaman on duty that he was going to bed. At 6.15 a.m. he was found missing and a search was undertaken. The dead body	 however	 was not found either on that day or later on. The evidence does not show that it was a stormy night. The Commissioner made a local inspection of the ship and saw the position of the bridge and deck and found that there was a bulwark more than 31/2 feet. Nobody saw the missing seaman at the 'so called place of accident. The Additional Commissioner held that there was no material for holding that the death of the seaman took place on account of an accident which arose out of his. employment. In our opinion the Additional Commissioner did not commit any error of law in reaching his finding and the High Court was not justified in reversing it. For these reasons we hold that this appeal must be allowed and the judgment of the Bombay High Court dated March 5	 1965 must set be aside. R.K.P.S. Appeal allowed.

S who was employed as a deck hand on a ship was found missing on board. The respondent filed an application under section 3 of the Workmen 's Compensation Act claiming compensation for the death of S which according to him occurred on account of a personal injury caused by an accident arising out of and in the course of employment. The Additional Commissioner held that there was no evidence to show that the seaman was dead and there was in any event no evidence to justify the inference that the death of the seaman was caused by an accident which arose out of employment. The High Court reversed the judgment of the Additional Commissioner. In appeal to this Court	 HELD: The Additional Commissioner did not commit any error of law in reaching his findings and the High Court was not justified in reversing them. To come within the Act the injury by accident must arise both out of and in the course of employment. The words "in the course of employment" mean in the course of work which the workman is employed to do and which is incidental to it. The words "arising out of the employment" are understood to mean that during the course of the employment	 injury has resulted from some risk incidental to the duties of the service	 which	 unless engaged in the duty owing to the master	 it is reasonable to believe the workman would not otherwise have suffered. The expression is not confined to the mere nature of the employment but applies to the employment as such to its nature	 its conditions	 its obligations and its incidents. [872 H] Although the onus of proving that the injury by accident arose both out of and in the course of employment rests upon the applicant these essentials may be inferred when the facts proved justify the inference. On the one hand the Commissioner must not surmise	 conjecture or guess; on the other hand he may draw an inference from the proved facts so long as it is a legitimate inference. The evidence must be such as would induce a reasonable man to draw the inference. [873 H] Lancashire and Yorkshire Railway Co. vs Highley	 	 Lancaster vs Blackwell Colliery Co. Ltd. 1918 W.C.
