The coroner who presided over an inquest into Amy Winehouse's death has resigned after it emerged that she did not have the correct qualifications.
The resignation raises the possibility that the investigation into the "Back to Black" soul singer's death last July may have to be held again.
Suzanne Greenaway had been appointed assistant deputy coroner in Camden, inner north London, in 2009 by her husband, Dr. Andrew Reid, several news outlets reported.
According to the Independent, coroners in the UK — who can be either lawyers or doctors — must have been registered with a professional body there for at least five years.
Greenaway had practised as an attorney in Australia from 1999, but arrived in the UK less than three years ago, the paper wrote.
The Australian newspaper reported that Greenway is originally from Tasmania.
"I believed at the time that her experience as a solicitor and barrister in Australia satisfied the requirements of the post," Reid said in a statement reported by the Associated Press on Wednesday. "In November of last year it became apparent that I had made an error in the appointment process and I accepted her resignation."
The local authority, Camden Council, said it was confident Reid "had made an error in good faith" in appointing his wife, but he but may have breached professional guidelines, the AP wrote.
The matter was being investigated by Britain's Office for Judicial Complaints, with the UK's Chief Justice, Lord Igor Judge ordering an official inquiry into Reid's conduct.

Greenaway also reportedly oversaw 12 inquests in Camden, the borough where Winehouse lived and died, and about 30 in total over two and a half years.
Officials are now contacting the relevant families to ask if they want new inquests, The Australian wrote.
According to the AP, Winehouse’s inquest could be declared invalid if her family challenges the verdict in court.
However, the 27-year-old Grammy winner's father, Mitch, downplayed the likelihood of that Wednesday, reportedly tweeting: “Don’t worry about coroner nonsense. We are all OK.”
