Suzanne Greenway, the coroner who ruled that the British singer died of accidental alcohol poisoning, resigned in November after officials learned she was not a lawyer in Britain for the necessary five years, the Associated Press reports. The news was confirmed Wednesday.

In Great Britain, “corners are independent judicial officers,” according to the Ministry of Justice.

The Winehouse family now has the option to ask for another investigation, and are “taking advice on the implications of [Greenway’s resignation] and will decide if any further discussion with the authorities is needed,” they said in a statement to the AP.

Winehouse’s father Mitch, who plans to write a memoir about his late daughter, tweeted Wednesday, “Don't worry about coroner nonsense. We are all ok.”

The 27-year-old soul singer was found dead last July in her London home. Winehouse was cremated after a private funeral service was held for friends and family. Greenway set down the verdict of alcohol induced “death by misadventure” in October.
