“23. I think what I have said above is basic principle. In the light of Miss Gumb’s argument I will add a little more on the question of divisibility. It is helpful to cite a passage from Devlin LJ in Dingle [ v Associated Newspapers Ltd[1961] QB 162 ] at pages 188 to 189: “This conclusion appears to me to be in accordance with, and indeed to exemplify, a fundamental principle in the law of damage. Where injury has been done to the plaintiff and the injury is indivisible, any tortfeasor whose act has been a proximate cause of the injury must compensate for the whole of it. As between the plaintiff and the defendant it is immaterial that there are others whose acts also have been a cause of the injury and it does not matter whether those others have or have not a good defence. These factors would be relevant in a claim between tortfeasors for contribution, but the plaintiff is not concerned with that; he can obtain judgment for total compensation from anyone whose act has been a cause of his injury. If there are more than one of such persons, it is immaterial to the plaintiff whether they are joint tortfeasors or not. If four mean, acting severally and not in concert, strike the plaintiff one after another and as a result of his injuries he suffers shock and is detained in hospital and loses a month’s wages, each wrongdoer is liable to compensate for the whole loss of earnings. If there were four distinct physical injuries, each man would be liable only for the consequences peculiar to the injury he inflicted, but in the example I have given the loss of earnings is one injury caused in part by all four defendants. It is essential for this purpose that the loss should be one and indivisible; whether it is so or not is a matter of fact and not a matter of law. If, for example, a ship is damaged in two separate collisions by two wrongdoers and consequently is in dry dock for a month for repairs and claims for loss of earnings, it is usually possible to say how many days’ detention is attributable to the damage done by each collision and divide the loss of earnings accordingly.” 24. It is, therefore, clear in principle that when there are competing causes for an injury a Court or Tribunal must consider the question of divisibility: both whether the injury is divisible and how it may be divided between the causes. The two questions go together and are essential elements of the reasoning. 25. The passage which I have quoted from Dingle also seems to me to indicate a common sense approach to divisibility. It is more likely that an injury will be held to be indivisible if the competing causes are closely related to the injury and it is difficult to separate out their consequences. Each case will depend on the evidence; the principles are the same where the injury is psychiatric but such is the complexity of the human mind that it may, in practice, be difficult to separate out the impact of different causes. This is why the application of the principles to psychiatric injury may not be straightforward: see the discussion in [ BAE Systems (Operations) Ltd v ] Konczak [[2014] IRLR 676 ] at paragraphs 34 to 39. But in each individual case the exercise must be undertaken, as [HHJ] Hand QC observed in that case.”
