After summarising the case law, the court in this case stated that there is a high threshold to be reached in order for ill health or physical disability to impinge upon the court's approach to assessing the appropriate method of sentencing an offender. This is not to say that ill health or disability will never be taken into consideration as is indicated by these terms: ‘not generally’, ‘not automatically’, ‘can take account’, ‘may enable’, ‘not in itself’, ‘it may be permissible’, ‘in appropriate cases’, ‘permissible to have regard’ and ‘purely on the basis’.

Lavery, R v (Sentencing Remarks) [2026] NICC 5

The parties disagreed on the extent of the repairs required to the joists, and the manner in which the repairs should be effected, following the collapse of part of the ceiling in a building owned by the Claimant and partly leased by the Defendant. The Judge found that the Defendant’s expert’s failure to engage with all the available evidence and to seek to undertake a fuller examination of the joists meant that his evidence did not fully address the issues before the court.

The case concerned around 40 studio recordings of performances which were given by the members of the Jimi Hendrix Experience.

The judge found that the accountancy reports were not expert evidence but simply aids to understanding the details in a complex case.

The dispute was between a former husband and wife, who were Russian nationals, about a post-nuptial agreement. The judge found that much of the expert evidence on Russian law was misdirected and misspent, and of limited use. He emphasised that both experts acted at times as surrogate advocates on behalf of their instructing parties.

The claimant was suing for the unpaid balance of the purchase price of assets used in its high-pressure aluminium diecasting business. The defendants’ expert received instructions that limited the scope of his investigation and analysis. While the judge accorded less weight to his evidence, he did not accept the claimant’s suggestion that the defendants’ expert ought to have either declined the instructions or proffered his opinion on wider valuation issues even in relation to issues outside of his instructions.
