l Appeal No 1827 of 1967
Appeal by special leave from the judgment and order dated the 29th April 1966 of the Rajasthan High Court at Jodhpur in D B Civil Regular First Appeal No 57
U N Trivedi and Ganpat Rai for the Appellants
Sobhagmal Jain for the respondent
The Judgment of the court was delivered by MATHEW J
This is an appeal by special leave against the judgment and decree of the High Court of Rajasthan setting aside decree for recovery of damages under the Patel Accidents Act 1855 hereinafter referred to as the 551 Navneetlal was a resident of Udaipur
He was in the employment of the State of Rajasthan and was at the material time working in the office of the Executive Engineer Public Works Department Bhilwara as a Store Keeper
In connection with the famine relief works undertaken by the department he was required to proceed to Banswara
For that purpose he boarded truck No RJE 131 owned by the department from Bhilwara on May 19 1952 and reached Chittorgarh in the evening
Besides himself there were Fateh Singh Fundilal and Heera Singh the driver cleaner and a stranger in the truck
On May 20 1952 they resumed the journey from Chittorgarh at about 11 A M and reached Pratapgarh in the same evening
The truck started from Pratapgarh to Banswara at about 10 AM on May 21 1952
After having travelled for 4 miles from Pratapgarb the engine of the truck caught fire
As soon as the fire was seen the driver cautioned the occupants to jump out of the truck
Consequently Navneetlal and the other persons jumped out of the truck
While doing so Navneetlal struck against a stone lying by the side of the road and died instantaneously
Parwati Devilwidow of Navneetlal brought a suit against the State of Rajasthan for damages under the provisions of the Act The plaintiff alleged that it was on account of the negligence of the driver of the truck that a truck which was not road worthy was put on the road and that it caught fire which led to the death of Navneetlal and that the State was liable for the negligence of its employees in the course of his employment
The plaint also alleged that the decreased had left behind him his widow  namely the plaintiff two minor sonsone minor daughter and his parents
The plaintiff claimed damages to the tune of Rs 20000 and prayed for a decree for that amount
The State contended that the truck was quite in order when it started from Bhilwara and even when it started from Pratapgarh to Banswara and that if it developed some mechanical troubles suddenly which resulted in its catching fire the defendant was not liable as there was no negligence the part of the driver
The trial court found that the act of the driver in putting the truck on the road was negligent as the truck was not roadworthy and since the driver was negligent the State was vicariously liable for his act
The Court assessed the damages at Rs 14760 and granted a decree for the amount to this plaintiff
It was against this decree that the State appealed to the High Court
The High Court came to the conclusion that the plaintiff had not proved by evidence that the driver was negligent that the mere fact that the truck caught fire was not evidence of negligence on his part and that the maxim res ipsa loquitur had no application
The Court said that the truck travelled safely from Bhilwara to Pratapgarh and that the engine caught fire after having 552 travelled a distance of 4 miles from Pratapgarh and that there was nothing on record to show that the engine of the truck was in any way defective or that it was not functioning properly
The Court was of the view that the mechanism of an automobile engine is such that with all proper and careful handling it can go wrong while it is on the road for reasons which it might be difficult for a driver to explain
The Court then discussed the evidence and came to the conclusion that no inference of negligence on the part of the driver was possible on the basis that the engine of the truck got heated of and on and that water was put in the radiator frequently or that it took considerably long time to cover the distance between Bhilwara and Chittorgarh and that between Chittorgarh and Pratapgarh
The High Court therefore allowed the appeal
The main point for consideration in this appeal is whether the fact that the truck caught fire is evidence of negligence on the part of the driver in the course of his employment
The maxim res ipsa loquitur is resorted to when an accident is shown to have occurred and the cause of the accident is primarily within the knowledge of the defendant
The mere fact that the cause of the accident is unknown does not prevent the plaintiff from recovering damage if the proper inference to in drawn from the circumstances which are known is that it was caused by the negligence of the defendant
The fact of the accident may sometimes constitute evidence of negligence and then the maxim res ipsa loquitur applies
The maxim is stated in its classic form by Erle C J  Where the thing is to shown to be under the management of the defendant or his servants and the accident is such as in the ordinary course of things does not happen if those who have the management use proper care it affords reasonable evidence in the absence of explanation by the defendants that the accident arose from want of care
 The maxim does not embody any rule of substantive law nor a rule of evidence
It is perhaps not a rule of any kind but simply the caption to an argument on the evidence
Lord Shaw remarked that if the phrase had not been in Latin nobody would have called it a principle 2
The maxim is only a convenient label to apply to a set of circumstances in which the plaintiff proves a case so as to call for a rebutting from the defendant without having to allege and prove any specific act or omission on the part of the defendant
The principal function of the maxim is to prevent injustice which would result if a plaintiff were invariably compelled to prove the precise cause of the accident and the dependent responsible for it even when the facts bearing on the matter are at the outset unknown to him and often within the knowledge of the defendant
But though the parties  relative access to evidence is an influential factor it is not controlling
Thus the fact that 1 See SCOtt vs London St Katherine Docks   601
2 See Ballard vs North British Railway Co 1923 section C HL 43
553 the defendant is as much at a loss to explain the accident or himself died in it does not preclude an adverse inference against him if the odds otherwise point to his negligence see John G Fleming The Law of Torts 4th ed p 264
The mere happening of the accident may be more consistent with the negligence on the part of the defendant than with other causes
The maxim is based on common sense and its purpose is to do justice when the facts bearing on the causation and on the care exercised by defendant are at the outset unknown to the plaintiff and are or ought to be within the knowledge of the defendant see Barkway vs section Wales Transport1
The plaintiff merely proves a result not any particular act or
omission producing the result
If the result in the circumstances in which he proves it makes it more probable than not that it was caused by the negligence of the defendant the doctrine of res ipsa loquitur is said to apply and the plaintiff Will be entitled to succeed unless the defendant by evidence rebuts that probability
The answer needed by the defendant to meet the plaintiff Is case may take alternative forms
Firstly it may consist in a positive explanation by the defendant of how the accident did in fact occur of such a kind as to exonerate the defendant from any charge of negligence
It should be noticed that the defendant does not advance his case inventing fanciful theories unsupported by evidence of how the event might have occurred
The whole inquiry is concerned with probabilities and facts are required not mere conjecture unsupported by facts
As Lord Macmillan said in his dissenting judgment in Jones vs Great Western 2 The dividing line between conjecture and inference is often a very difficult one to draw
A conjecture may be plausible but it is of no legal value for it sessense is that it is a mere guess
An inference inthe legalsense on the other handis a deduction from the evidence and if it is are a sonable deduction it may have the validity of legal proof
The attribution of an occurrence to a cause is I take it always a matter of inference
The cogency of a legal inference of causation may vary in degree between practical certainty and reasonable probability
Where the coincidence of cause and effect is not a matter of actual observation there is necessarily a hiatus in the direct evidence but this may be legitimately bridged by an inference from the facts actually observed and proved
 In other words an inference is a deduction from established factsand an assumption or a guess is something quite different but not necessarily related to established facts
1 1950 1 All England Reports 392 399
7 M 45 Sup CI75 2 554 Alternatively in those instances where the defendant is unable to explain the accident it is incumbent upon him to advance positive proof that he had taken all reasonable steps to avert foreseeable harm
Res ipsa loquitur is an immensely important vehicle for importing strict liability into negligence cases
In practice there are many cases where res ipssa loquitur is properly invoked in which the defendant is unable to show affirmatively either that he took all reasonable precautions to avoid injury or that the particular cause of the injury was not associated with negligence on his part
Industrial and traffic accidents and injuries caused by defective merchandise are so frequently of this type that the theoretical limitations of the maxim are quite overshadowed by its practical significance 1
Over the years the general trend in the application of the maxim has undoubtedly become more sympathetic to plaintiffs
Concomitant with the rise in safety standards and expanding knowledge of the mechanical devices of our age less hesitation is felt in concluding that the miscarriage of a familiar activity is so unusual that it is most probably the result of some fault on the part of whoever is responsible for its safe performance see John G Fleming The Law of Torts4th ed p 260
We are inclined to think the learned District Judge was correct in inferring negligence on the part of the driver
Generally speaking an ordinary road worthy vehicle would not catch fire
We think that the driver was negligent in putting the vehicle on the road
From the evidence it is clear that the radiator was getting heated frequently and that the driver was pouring water in the radiator after every 6 or 7 miles of the journey
The vehicle took 9 hours to cover the distance of 70 miles between Chittorgarh and Pratapgarh
The fact that normally a motor vehicle would not catch fire if its mechanism is in order would indicate that there v as some defect in it
The District Judge found on the basis of the evidence of the witnesses that the driver knew about this defective condition of the truck when he started from Bhilwara
It is clear that the driver was in the management of the vehicle and the accident is such that it does not happen in the ordinary course of things
There is no evidence as to how the truck caught fire
There was no explanation by the defendant about it
It was a matter within the exclusive knowledge of the defendant
It was not possible for the plaintiff to give any evidence as to the cause of the accident
In these circumstances we think that the maxim res ipsa loquitur is attracted
It was however argued on behalf of the respondent that the State was engaged in performing a function appertaining to its character as sovereign
as the driver was acting in the course of his employment in connection with famine relief work and therefore even if the driver 1 See Millner  Negligence in Modern Law
555 was negligent the State would not be liable for damages
Reliance was placed on the ruling of this Court in Kasturilal Ralia Ram Jain vs State of Uttar Pradesh 1 where this Court said that the liability of the State for a tort committed by its servant in the course of his emp loyment would depend upon the question whether the employ ment was of the category which could claim the special characteristic of sovereign power
We do not pause to consider the question whether the immunity of the State for injuries on its citizens committed in the exercise of what are called sovereign functions has any moral justification today
Its historic and jurisprudential support lies in the oftquoted words of Blackstone2  The king can do no wrong
The king moreover is not only incapable of doing wrong but even of thinking wrong he can never mean to do an improper thing  in him is no folly or weakness
In modern times the chief proponent of the sovereign immunity doctrine has been Mr Justice Holmes who in 1907 declared for a unanimous Supreme Court3  A sovereign is exempt from suit not because of any formal conception or obsolete theory but on the logical and practical ground that there can be no legal right as against the authority that makes the law on which the right depends
 Today hardly anyone agrees that the stated ground for exempting the sovereign from suit is either logical or practical
We do not also think it necessary to consider whether there is any rational dividing line between the so called sovereign and proprietary or commercial functions for determining the liability of the State
We are of the view that as the law stands today it is not possible to say that famine relief work is a sovereign function of the State as it has been traditionally understood
It is a work which can be and is being undertaken by private individuals
There is nothing peculiar about it so that it might be predicated that the State alone can legitimately undertake the work
In the view we have taken on the merits of the case we do not think it necessary to canvass the correctness of the view expressed by the High Court that the appeal by the State before the High Court did not abate even though the legal representatives of the plaintiff respondent there were not impleaded within the period of limitation
In the result we set aside the decree of the High Court restore the decree and judgment passed by the District Judge and allow the appeal with costs
