Does the face fit?
Case Updates

Does the face fit?

Experts are advised, if possible, to avoid expressing opinions on the basis of possibility. The usually applicable stand of proof is the civil standard – the balance of probabilities or more probable than not. The criminal standard of proof is beyond reasonable doubt (and not beyond all reasonable [sic] doubt as it is sometimes misquoted). In this case it was submitted that the expert used the terms "possibility", "high possibility" and "extremely high possibility" interchangeably and that this was insufficient to satisfy the criminal standard of proof. However, when the court analysed the expert’s report as a whole, it was clear that a tribunal of fact could safely conclude that the criminal standard of proof was satisfied.

Not a bridge too far – dental negligence
Case Updates

Not a bridge too far – dental negligence

The detail of this case is of relevance to dental experts and attention is drawn to the clarity and particularity with which Professor Harding set out the instances of treatment of the Claimant which was below the standard she could reasonably have expected and then identified the consequences thereof. There is a gastroenterological and pharmacological dimension to the case because it was alleged, and found, that the pain resulting from the negligent dental treatment necessitated treatment with NAISDs which caused ischaemic colitis.
