"If in the course of his work the Plaintiff came across a window the cleaning of which presented some unusual difficulty, and the Plaintiff was in doubt whether he could clean it safely, then the system was that be should leave the window uncleaned, report the fact to the Defendants, and ask for further instructions. He was told to do this when he first joined the Defendant firm in 1942. Mr. Waller says that to call that a system was putting the matter higher than the evidence justified. But I do not think that that criticism is made out. Then the learned Judge continued: "
"The next question is whether the contractors are liable to their workman, the plaintiff. Counsel for the contractors argued that employers who send their men out to work on the premises of other people have no responsibility for the safety of those premises. Be cited Taylor v. Sims & Sims in support of that proposition. He said that it was for the occupier to see that the premises were safe for the workman and not for the employer to do so. I cannot agree with that proposition. Until recently many people thought that an occupier was bound to use reasonable care to see that his premises were safe for workmen he invited on them, but that is no longer true. The decision of the House of Lords in London Graving Dock Company Limited v. Horton shows that an occupier can allow his premises to remain defective and dangerous with impunity so long as he gives the men warning that the risk or the danger is so obvious that they must be aware of it. If this is so, I think it must follow that it is for the employer, who sends his men to the premises, to take reasonable care to see that the premises are safe for the men, or else take proper steps to protect the men from the dangers to which he sends them. The learned Lord Justice was in effect saying that Horton's case had left a gap which must be filled by imposing on the employer a liability for dangers for which the invitor might no longer be liable. The learned Judge observed that the other members of the Court of Appeal had based their Judgments on somewhat different grounds and that in the House of Lords the decision in the Plaintiff's favour was based on a shortcoming in the system employed to clean the windows rather than a failure to inspect the windows before each periodical cleaning. He then referred to Cilia v. James & Sons and. Taylor v. Sims & Sims , in each of which cases the learned Judges held that where an employer sent out his men to work on the premises of others there was no duty of care on him in respect of those premises and that, if there were, the duty had, on the particular facts of each case, been discharged. He also referred to Hodgson v. British Arc Welding Company Limited (1946 King's Bench, page 302), in which Mr. Justice Hilbery dealt with a similar point in a somewhat different and, as it seems to me, a preferable way. The implications of his Judgment are' not that the employers had no duty at all in respect of things over which they had no control but that the discharge of that duty was of a wholly different kind from that where the master was in control. The learned Judge then continued as follows: "
"Rare, again, I agree with the view of the Scottish courts that it was not proved to be part of the regular practice or course of duty of stevedoring firms to make such inspection"
"In my opinion, if the employer uses plant which is net his own for the purpose of doing something which he has engaged to do, it cannot possibly be said that he has no duty whatever in relation to that plant. Otherwise he would be able to take anything that came from anybody and to use anything in the work he was engaged upon without making any inquiry at all, and then say, in the event of an injury arising from a defect in the plant, that he had nothing to do with it, and so escape liability. That, to my mind, is unreasonable, and is not consistent with the second section. What I take to be the meaning of that is that if the employer uses plant which does not belong to him, he may have a duty in regard to the persons employed to take reasonable care to see that it is proper for the purpose for which it is need. It may be that in a case of this character, although he had that duty, yet, if he had dealt with these shipowners before and had never had any cause for complaint, the jury might think that he had reasonably discharged that duty. On the other hand, when you have evidence that the plant was old and had been in use for a long time, the jury might say they ware not satisfied that reasonable care had been taken to see that it was in a proper condition. Once establish the duty the question la, What would the jury consider a discharge of that duty?"
