The probe of Amy Winehouse's death has been reopened following the resignation of Suzanne Greenaway and subsequent questions as to her the validity of her legal credentials, CNN reports.

Greenway, the coronoer who ruled the singer died of alcohol poisoning, was appointed by her husband, London Coroner Andrew Reid. However, it was discovered that she had not been a registered lawyer in the United Kingdom for the requisite five years, which has lead Winehouse's case to be re-visited. The pathologist's tests revealed that Winehouse's blood-alcohol level was 416 milligrams per 100 milliliters of blood. The level considered lethal is 350 milligrams per 100 milliliters of blood, and the legal limit to drive in Britain is 80 milligrams of alcohol. A new coroner's inquest into Winehouse's death will begin on January 8, London's Camden Council announced Monday.

Found dead after a very public battle with drugs and alcohol in her north London home on July 23, 2011, Winehouse's death hit The U.K hard. The Grammy award-winning artist's success came with her 2007 album "Back to Black." She dominated the 2008 Grammys, winning five awards that night. Her niche style, candid nature and undoubtable talent made her one of Britain's most loved talents. Her first album, "Frank," debuted in 2003, when she was just 19.
