The decision in City Inn vs Shepherd Construction is a victory for common sense over philosophical arguments about causation, says the lawyer who acted for Shepherd
Since the introduction of the Construction Act, JCT disputes regarding loss and expense and extensions of time have, in the main, been resolved by adjudication. This is perhaps one reason for the high level of interest in the November 2007 opinion of Lord Drummond Young in the case of City Inn vs Shepherd Construction. However, what really provoked discussion was Drummond Young鈥檚 apparent rejection of detailed critical path analysis in favour of a more practical assessment of the impact of delay events, together with an 鈥渁pportionment鈥 exercise where there was no 鈥渄ominant cause鈥 of delay.
City Inn appealed against Drummond Young鈥檚 decision, arguing that his approach was misconceived. The Scottish Court of Appeal issued its judgment on 22 July, and it amounts to an endorsement of Drummond Young鈥檚 approach.
City Inn employed Shepherd under an amended JCT80 contract to construct a hotel in Bristol. The project ran late, and after a series of adjudications Shepherd was awarded a five-week extension. Thereafter, City Inn raised proceedings in the Court of Session seeking a declaration that Shepherd was not entitled to a single day鈥檚 extension, and therefore was liable for liquidated damages. The evidence appeared to suggest that there was 鈥渃oncurrency鈥 between certain relevant events and other causes of delay. It was against that background that Drummond Young reviewed the authorities on clause 25 of JCT.
Whether or not the relevant event causes delay is not an issue to be resolved on philosophical principles
In summary, he concluded that the task of the decision maker under clause 25 was to arrive at a 鈥渇air and reasonable鈥 decision on an extension. Where the relevant event and the contractor risk event existed at the same time, irrespective of when the events began (or ended), in the absence of one being 鈥渄ominant鈥, achieving a fair and reasonable outcome may involve an apportionment exercise.
In reaching this view, Drummond Young also noted that the 鈥渂ut for鈥 test of causation did not apply in the context of clause 25. He went on to find Shepherd entitled to a nine-week extension. City Inn appealed.
All three appeal judges rejected City Inn鈥檚 grounds of appeal. The main opinion was delivered by Lord Osborne. He endorsed the approach taken by Drummond Young and set out five propositions relative to the proper approach to the application of clause 25.
n Before any claim for an extension can succeed, it must be shown that the relevant event is likely to delay or has delayed the works.
n Whether or not the relevant event actually causes delay is 鈥渁n issue of fact that is to be resolved, not by the application of philosophical principles of causation, but rather by the 鈥 principles of common sense鈥.
n The decision maker can decide the question of causation by the use of whatever evidence they consider appropriate. If demonstrated to be sound, this may take the form of a critical path analysis, but the absence of such an analysis does not mean the claim will necessarily fail.
n If a dominant cause can be identified in respect of the delay, effect will be given to that by leaving out of the account any cause or causes that are not material. If the dominant cause is not a relevant event, the claim will fail.
n Where there are two causes behind the delay, neither of which is dominant and only one of which is a relevant event, a contractor鈥檚 claim for an extension will not necessarily fail. Rather, it is for the decision maker 鈥渁pproaching the issue in a fair and reasonable way, to apportion the delay in completion of the works 鈥 between the relevant event and the other event鈥.
Osborne appears to be unimpressed by the attempts to classify 鈥渃oncurrent delay鈥 or 鈥渃oncurrent delaying events鈥 stating that 鈥渄iscussion of whether there is true concurrency, in my opinion, does not assist in the essential process to be followed under clause 25鈥.
The decision does not amount to a rejection of critical path analysis, and in many circumstances it may well be appropriate for the decision maker to have regard to it. But in its absence, a claim will not necessarily fail.
Taken together, the decisions amount to an endorsement of the application of common sense and a rejection of what the court described as 鈥減hilosophical鈥 arguments about concurrency and causation.
