Gambling with Lives suggested that another way of collating statistics about the numbers of gambling-related suicides might be through changes to medical recording and the coronial process https://www.suissecasinoenligne.com/casino-en-direct/.
It is not, and never has been, part of the duties of coroners to record the reason for a death; they have always been limited to discovering “who, when, where and how”, but not “why” a person died; indeed there is a statutory prohibition on such a finding.
There is a good reason for this: “why” often involves deciding that a criminal offence has been committed, often with an indication of the likely perpetrator, and this would impact on the criminal process and might prejudice a fair trial. But the result is that a finding that a death was the result of suicide will not say that the suicide was caused in whole or in part by gambling, even if the coroner believes that this was the case. Coroners’ offices therefore have no record of gambling-related suicides.
