The High Court has refused a judicial review application challenging a coroner’s verdict that Paul Byrne died by misadventure. The court held that the coroner had detailed medical evidence supporting his decision and that the applicant had not demonstrated an improper exercise of discretion or a procedural irregularity.
Fiona Byrne, Mr Byrne’s widow, had sought to quash the coroner’s determination and obtain a declaration that the Coroners Act 1962, as applied to the case, contravened the European Convention on Human Rights. Mr Byrne, aged 37, died on 9 November 2005 after suffering chest pain and dizziness. He had been hospitalised the previous month with a blood clot and was taking medication.
At the inquest in August 2006, the coroner recorded death by misadventure, citing coronary problems and cannabis use as primary and secondary causes. The final pathology report also identified steatohepatitis as a contributory factor. Mrs Byrne disputed the cannabis finding and argued that the inquest did not adequately consider other possible causes, including the effect of an ambulance delay and a possible genetic predisposition to coronary disease. She also said the inquest proceeded too quickly and in language she could not understand.
The coroner said he offered to adjourn the inquest to gather evidence and witnesses about the ambulance delay after Mr Byrne’s father refused the offer. He understood that Mrs Byrne did not object. He also relied on the pathologist’s findings and supporting medical literature concerning cannabis use and heart events. The applicant’s submissions included studies disputing that view; the court noted that no contrary evidence had been presented to the coroner or application made to obtain it.
Justice Hedigan said the judicial review concerned how the coroner reached his decision, rather than the court reconsidering the substance of the medical findings. The coroner had a detailed post-mortem and toxicology report, and the court considered this relevant evidence on which a decision could reasonably be based. The court said whether to seek differing medical viewpoints was within the coroner’s discretion.
The judge also found no impropriety in the decision not to investigate the ambulance delay further, noting Mrs Byrne was present when the adjournment was refused. He stressed that an inquest is inquisitorial and must not determine civil or criminal liability. The court refused both forms of relief sought.
