“1. Duty of occupier to persons other than his visitors (1) The rules enacted by this section shall have effect, in place of the rules of the common law, to determine — (a) whether any duty is owed by a person as occupier of premises to persons other than his visitors in respect of any risk of their suffering injury on the premises by reason of any danger due to the state of the premises or to things done or omitted to be done on them; and (b) if so, what that duty is... (3) An occupier of premises owes a duty to another (not being his visitor) in respect of any such risk as is referred to in subsection (1) above if — (a) he is aware of the danger or has reasonable grounds to believe that it exists; (b) he knows or has reasonable grounds to believe that the other is in the vicinity of the danger concerned or that he may come into the vicinity of the danger (in either case, whether the other has lawful authority for being in that vicinity or not); and (c) the risk is one against which, in all the circumstances of the case, he may reasonably be expected to offer the other some protection. (4) Where, by virtue of this section, an occupier of premises owes a duty to another in respect of such a risk, the duty is to take such care as is reasonable in all the circumstances of the case to see that he does not suffer injury on the premises by reason of the danger concerned. (5) Any duty owed by virtue of this section in respect of a risk may, in an appropriate case, be discharged by taking such steps as are reasonable in all the circumstances of the case to give warning of the danger concerned or to discourage persons from incurring the risk. (6) No duty is owed by virtue of this section to any person in respect of risks willingly accepted as his by that person (the question whether a risk was so accepted to be decided on the same principles as in other cases in which one person owes a duty of care to another)”
“34. In the ordinary run of litigation in the courts the legal rights of the parties fall to be decided in accordance with the facts as they appear to the first instance judge. There is little room for the admission of evidence of changed circumstances at the hearing of an appeal. From time to time, however, such evidence was admitted. Case law reveals the following examples under the pre-CPR regime: i) Where there has been a change of circumstances after the granting of an interlocutory injunction such that if the new circumstances had been before the judge they would have justified the variation of the injunction (Hadmor Productions Ltd v Hamilton[1983] 1 AC 191 , 220D); ii) More generally, where a change of circumstances since the trial has falsified the basis on which discretionary relief was granted (Attorney General v Birmingham, Tame and Rees District Drainage Board[1912] AC 788 , 802); iii) Where the passage of time since a trial has falsified a conclusion of the trial court based on complaints of delay (EMA v ACAS (No 2)[1980] 1 WLR 302 , 320F); iv) From time to time, on the basis that the court should not speculate where it knows, damages will be assessed on the facts as they appear at the date of the appeal hearing (Curwen v Jones[1963] 1 WLR 748 , 753; Lim Poh Choo v Camden and Islington AHA[1980] AC 174 , 194E). 35. In Murphy v Stone-Wallwork (Charlton) Ltd[1969] 1 WLR 1023 HL it was said that the power to admit fresh evidence which showed that damages had been assessed on a false basis should be exercised very sparingly in view of the importance of the principle of finality in litigation (see Lord Pearce at p 1028B and Lord Upjohn at p 1031A). 36. RSC Order 59 Rule 10, which was the rule in force in the Court of Appeal prior to2nd May 2000 , provided that: “(2) The Court of Appeal shall have power to receive further evidence on questions of fact…but in the case of an appeal from a judgment after trial or hearing of any cause or matter on the merits, no such further evidence (other than evidence as to matters which have occurred since the date of the trial or hearing) shall be admitted except on special grounds. (emphasis added) (3) The Court of Appeal shall have power to draw inferences of fact and to give any judgment and make any order which ought to have been given or made, and to make such further or other order as the case may require.” 37. It is noticeable that the court’s willingness to admit evidence of changed circumstances was exercised in particular when it was determining whether a restraint as to future conduct should be retained in force or lifted, or whether an award of damages which contained a significant element of crystal-gazing should be altered when more of the material facts had become known. In all these cases the court possessed an appellate jurisdiction over both fact and law”. “(2) The Court of Appeal shall have power to receive further evidence on questions of fact…but in the case of an appeal from a judgment after trial or hearing of any cause or matter on the merits, no such further evidence (other than evidence as to matters which have occurred since the date of the trial or hearing) shall be admitted except on special grounds. (emphasis added) (3) The Court of Appeal shall have power to draw inferences of fact and to give any judgment and make any order which ought to have been given or made, and to make such further or other order as the case may require.”
“In deciding whether the Appellant was a licensee, the question was, not whether his activity or similar activities might have been foreseen, but whether they had been impliedly assented to by the [occupier]…When a council licenses the public to use its land for recreational purposes, it is consenting to normal recreational activities, carrying normal risks. An implied licence for general recreational activity cannot, in my view, be stretched to cover any form of activity, however reckless.”
