Suzanne Greenaway, the coroner who oversaw the Amy Winehouse death examination, resigned in November, after authorities found out she lacked the proper credentials. The resignation was made public Wednesday. Now the late star's family is thinking of asking for a new investigation. Greenaway resigned after authorities' learned that the coroner had not been a registered U.K. lawyer for five years.

The London coroner who appointed her is Andrew Reid, her husband.

I appointed my wife as an assistant deputy coroner as I believed at the time that her experience as a solicitor and barrister in Australia satisfied the requirements of the post. In November of last year it became apparent that I had made an error in the appointment process and I accepted her resignation, Reid said in a statement on Wednesday.

Greenway had originally practiced law in her Australian homeland. In 2009 she was appointed the assistant deputy coroner in London by Reid.

The matter is being investigated by Britain's Office for Judicial Complaints. But, according to Boston.com, local authority, Camden Council, believes that Reid had made an error in good faith.

Although the London Coroner maintains that the inquest of Winehouse's death, along with the others Greenaway oversaw, were done correctly, USAToday.com states that he is offering the families of the deceased the option of holding the inquests over again.

According to USAToday.com, Winehouse's family had not yet decided what to do. The family released a statement saying that they are taking the advice on the implications of this and will decide if any further discussion with the authorities is needed.

In October, Greenaway ruled that Winehouse suffered accidental alcohol poisoning. Evidence from a pathologist and Winehouse's doctor were included in the inquest; as were statements from the security guard, who found her, and a detective, who witnessed the three empty vodka bottles found in her room.
