“The Court of Appeal or the High Court will not reopen a final determination of any appeal unless – (a) it is necessary to do so in order to avoid real injustice; (b) the circumstances are exceptional and make it appropriate to reopen the appeal; and (c) there is no alternative effective remedy.”
“27. … That is of particular relevance, because the thrust of the applicants’ case was and is that there has been an inadequate assessment of the marine risks associated with the terminal proposals. The Milford Haven Port Authority is a statutory body required to ensure the safety of waters within its jurisdiction. The evidence before Sullivan J made it clear that the Port Authority was satisfied as to the safety of the terminal proposals, so far as its own sphere of responsibility was concerned, while the Health and Safety Executive had advised that it was content so far as the land-based activities were concerned. Both these bodies had so advised the decision-makers, the County Council and the Park Authority, who were entitled to rely on the specialist advice received from those bodies. 28. In those circumstances, it seems to me that it was open to Sullivan J to conclude that the merits of the applicants’ claim did not outweigh the undue delay and the prejudice which permission to proceed would produce. This court has held that striking such a balance is a matter of discretion for the judge dealing with the application, and that this court will not intervene unless there has been an error of principle: R v. Vale of Glamorgan Borough Council, ex parte James [1997] Env. L.R. 195. I am not persuaded that any such error in Sullivan J’s approach has been shown, nor is his decision obviously wrong. He was entitled to reach the conclusion which he did. 29. That being so, it is strictly speaking unnecessary to scrutinise in greater depth the decisions of the County Council and Park Authority, who granted the planning permissions and hazardous substances consents. But we have had detailed submissions addressed to us about those decisions and the alleged deficiencies in them, and I therefore propose to address briefly the issues raised.”
“32. I do not accept that the evidence before us, including the evidence submitted on behalf of the applicants since the oral hearing, demonstrates any such arguable lacuna. One has to bear in mind in this connection the very extensive assessments carried out by the Health and Safety Executive, because these provide the context for the Port Authority’s assessment. The Health and Safety Executive did assessments which considered both the consequences and the likelihood of an escape of LNG for all land-based and jetty-based activities. Those included the risks of catastrophic failure of an LNG storage tank at the terminal; the failure of a loading arm at the jetty while LNG was being transferred from ship to shore; and “major release from a delivery ship while tied up at a jetty”: see HSE responses to Park Authority,5 March 2004 , and the HSE Summary Grounds of Resistance, paragraphs 10 and 11. Having carried out these assessments the Health and Safety Executive did not object to the proposal for either terminal on safety grounds. The applicants do not criticise the work done by the Health and Safety Executive. 33. That body made it clear in its response of March 2004 that it was not responsible for advising on accidents “whilst the ship is not attached to the jetty”
