A doctor accused of failing to spot signs that Baby P was being abused has had her application to be removed from the medical register rejected.
Dr Sabah Al-Zayyat, who is facing disciplinary action over her conduct, had applied for "voluntary erasure" from the medical register.
This would have avoided the need for a full misconduct hearing.
The General Medical Council has ruled that the "serious" allegations against her should be heard in public.
The GMC could ban her from UK working.
Chairman Ralph Bergmann said: "The panel considers that to accede to the application for voluntary erasure would avoid a public, and necessary, examination of the facts of this case."
Dr Al-Zayyat saw 17-month-old Peter Connelly at St Ann's Hospital in Haringey days before his death in 2007.
She is accused of failing to carry out an "adequate examination", investigate his injuries or admit him to hospital.
A post-mortem examination found he had probably suffered serious injuries, including a broken back and fractured ribs, before he was examined by Dr Al-Zayyat.
Dr Al-Zayyat is also accused of knowing Peter was on the child protection register.
She had her contract with Great Ormond Street hospital terminated after details of Peter's case came to light.
Dr Al-Zayyat, who did not attend this latest hearing, was originally due to face GMC disciplinary action in February.
The earlier session was adjourned after the panel heard she was "suicidal", unfit to defend herself and had left the country.
Mary O'Rourke QC, for Dr Al-Zayyat, told the GMC panel she would go to the High Court to seek a judicial review of its decision not to allow voluntary erasure
