Amy Winehouse’s family were shocked to learn on Wednesday that the coroner at their daughter’s inquest was actually unqualified.

Suzanne Greenaway was appointed to the role of assistant deputy coroner by her husband Dr. Andrew Reid, who was confident that she would be able to handle the inquests appropriately. However, she resigned a month after she ruled that Amy had died from accidental alcohol poisoning.

The Back to Black star’s family have now enlisted the help of lawyers and the Office for Judicial Complaints to investigate Greenaway and her husband. Coroners in the UK must be in the Law Society for five years before they can become fully qualified and although Greenaway had been a lawyer in Australia for 10 years, she had only been a lawyer in England for two-and-a-half years.

Mitch Winehouse told The Sun:

We were very shocked when we were informed the coroner was not suitably qualified. It’s hard to believe her credentials weren’t fully checked. You’d assume this sort of thing can’t happen. We’ve been informed the coroner was taking guidance from more experienced professionals and the verdict doesn’t appear to be in any doubt, but it’s upsetting to have to go through all this again. We just hope that matters can be resolved soon.
