Email chains, gross misconduct and the experts who count the cost

Mrs Justice Joanna Smith provides an incredibly useful judgment following the hearing at the High Court in March of this year. Previous case law and legal tests for gross misconduct were addressed and applied given that such allegations underpinned the case.  The parties adduced expert evidence to establish the value of shares on the assumption that warranties had been breached.This update focuses on both experts’ evidence given that the approaches were significantly different and that one was clearly preferred over the other.

Legal teams need to observe Expert’s fatigue & concentration

This was a significant and well reported patent case which was determined in the Intellectual Property List within the High Court last autumn.   

The technical aspects of the case required significant expert input from the panel involved.  The cross-examinations performed by leading Counsel for the parties were lengthy and complicated.  This led to confusion over what evidence was given when the transcripts were re-visited on subsequent trial days. The case shows how consideration should be given to experts who are being cross-examined so not to overload them with questions and information on the stand.

Navigating the excessive difference in valuations from  two Expert Quantity Surveyors

Navigating the excessive difference in valuations from two Expert Quantity Surveyors

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.

How not to use AI in expert evidence

In this US case, an expert in fiduciary services used Microsoft’s Copilot to cross-check calculations he used in expert evidence. He was unable to recall the prompts he used, state the sources Copilot relied on, or explain how the tool worked and arrived at its outputs. The judge provided some useful insight into the challenges with using AI in expert evidence.
