The complexities of this case required both parties to engage expert quantity surveyors.  Both sides approached their instructions to their expert from different angles which caused difficulties at trial.  This explained why the valuations were worlds apart (or as the judge commented they had a “manifestly excessive difference”) and needed some careful scrutiny and assessment by the judge. Whilst the approach of examining both valuations is very case specific, there are some fundamental tests which can be taken away.  An objective test was used several times as a benchmark looking at the scope of works that a ‘reasonable owner’ or ‘purchaser’ would require.  The key legal issue of “proportionality” was also visited frequently throughout the assessment of valuations.

Gareth Jenkins gave evidence to the Post Office Horizon IT Inquiry from 25 to 28 June on the expert evidence he provided on the Horizon IT system. Mr Jenkins told the Inquiry that he had been unaware of his duties as an Expert Witness and had not been offered any training to support his role. The EWI offers comprehensive training on the core competencies of an Expert Witness. We urge policy and rule makers, and the judiciary, to consider how to ensure that Expert Witnesses fully understand their duties and know how to apply them.
