Doug joined Deans Court Chambers in September 2014. Prior to being called to the Bar in 2004, he worked for many years in the insurance industry, for Royal Insurance (now RSA), for NEM/AGF (now Allianz) and for the Iron Trades (now Chester Street Insurance Holdings and QBE) where he became the Regional Claims Manager. Most of this time was spent dealing with Employers’ and Public Liability cases, in latter years predominantly disease claims.
His work is almost exclusively for Defendants, insurers, large corporate clients, public authorities or funds. The vast majority of his work concerns occupational disease claims, predominantly in respect of medical causation. The vast majority of his work is multi track work given the complexity of the issues.
Clinical Negligence is a growing area of Doug’s practice. Two relevant cases this year concern neck surgery in which it was alleged that the surgeon had directed a facial nerve and abdominal surgery in which it was alleged that the surgeon had damaged the ileum, causing faecal peritonitis to develop. The Defendant was successful in both cases.
Doug also handles Product Liability claims and is regularly instructed by manufacturers of allegedly defective products.
Industrial Disease - Deafness Claim
Holloway -v- Tyne Thames Technology Limited (2015)
The only issue before the court was whether the Claimant’s noise induced hearing loss was sufficient to sound in damages. Exposure, that such exposure was in breach of duty, limitation and causation were not in issue.
The court was asked to decide if a hearing loss of between 0.8dB and 1.3dB (measured at the conventional speech frequencies of 1, 2 and 3kHz) or the diminution of the Claimant’s ability to hear sounds at 4kHz by about 10-15dB, was sufficient to sound in damages.
His Honour Judge Freedman heard evidence from Professor Homer for the Claimant and Professor Lutman for the Defendant and made the following findings:
1. A hearing loss at the conventional speech frequencies of 1, 2 and 3kHz of 3dB or less would not cause sufficient disability for the same to sound in damages.
2. The /f/, /th/ and /t/ sounds were heard over a range of frequencies and therefore a hearing loss of 10-15dB at 4kHz was insufficient to cause disability, given they would be perceived at other unaffected frequencies.
3. Although the sound /s/ may be frequency specific to 4kHz when made by some people, the Claimant’s hearing loss of 10-15dB at 4kHz would only cause her perception of such sounds to be diminished between about 40 and 55dB (she would have had similar disability as a consequence of age anyway between 30 and 45dB) but would have been unchanged at the level at which quiet conversational speech was perceived. Such a narrow ‘window of opportunity’ within which any theoretical disability may be manifest was insufficient to give rise to a claim for damages: de minimis non curat lex.
Personal Injury - Disease
Cran -v- Perkins Engines Limited (January 2013)
This was the first trial in which asymmetric hearing loss was alleged to be due to symmetric noise exposure. A copy of the judgment can be provided on request.
Personal Injury - Disease
Hughes -v- Rhondda Cynon Taf County Borough Council (3rd August 2012, Cardiff CC)
This was the first deafness case in which the principle of de minimis non curt lex was applied to noise damage. The Defendant successfully argued that the Claimant’s hearing loss at 4kHz (which was due to noise) did not cause him to be ‘appreciably worse off’ as his hearing at the speech frequencies of 1, 2 and 3kHz was well preserved.
Personal Injury - Hand Arm Vibration
Owens v Gwent CC
Case regarding the date of knowledge of local authorities regarding the use of gardening equipment (strimmers etc).
