The inquest into the death of singer Amy Winehouse is due to be reheard on Tuesday.
The Back To Black star was found dead at her north London home in July 2011, aged 27.
The move comes after an investigation found Suzanne Greenaway, who oversaw the inquest into Winehouse's death, did not have the correct qualifications for the role.
The new hearing is due to take place today at St Pancras Coroner's Court in London.
Greenaway recorded a verdict of misadventure at the original hearing in October 2011.
She was appointed to the role in July 2009 by her husband, Andrew Reid, who was the coroner for Inner North London, after she had worked as a solicitor and barrister in Australia.
But she stepped down in November when it emerged she did not have the requisite five years' experience in the Law Society.
Dr Reid resigned from his position last month after the Office for Judicial Complaints launched disciplinary proceedings against him.
Investigators found he had not "thoroughly" checked his wife had the requisite qualifications for the position.
The Lord Chancellor and the Lord Chief Justice had indicated their intention to remove Dr Reid from judicial office following the investigation.
But despite being entitled to challenge their decision, the senior coroner decided to stand down.
During her time as deputy assistant coroner, Greenaway conducted 12 inquests in Camden, but worked largely from Poplar Coroner's Court in east London.
According to British law, Ms Greenaway, who also worked as a nurse in Australia, would have needed either five years with the Law Society or five years of experience as a qualified medical practitioner.
She met neither set criteria.
A spokesman for the Winehouse family said last month when it was announced that the inquest would be reheard: "The family were happy with the way the original inquest was conducted and did not request it to be reheard.
"This seems to be a matter of procedure and the verdict is not expected to change."
Interim coroner for Inner North London Dr Shirley Radcliffe said last month: "I can confirm that an inquest into the death of Amy Winehouse will be heard at St Pancras Coroner's Court on Tuesday 8 January 2013.
"After taking the appropriate legal advice I am minded that due to the previous assistant deputy coroner's ineligibility to hold coronial office that the inquest into the death of Amy Winehouse had not technically been heard. I have therefore scheduled an inquest to take place where the evidence will be heard again in public before a judgment is made.
"Other inquests handled by Greenaway have been heard again by the coroner's court throughout the year following consultation with the next of kin.
"While I wish to ensure that due legal process is followed, I understand that these hearings have brought back many unwanted memories for the families and my sympathies are with them at this time."Suggest a correction
