Dr Southall said he wanted to work doing "humanitarian work abroad"
Paediatrician David Southall has overturned a ban which stopped him working as a doctor.
The General Medical Council struck off Dr Southall for serious professional misconduct. His appeal is continuing.
But it admitted at the High Court it was wrong to apply 2004 guidelines retrospectively in enforcing the ban.
Dr Southall, still employed at the North Staffordshire University Hospital, remains banned from undertaking child protection work.
He was barred from working as a doctor after the GMC decided he had abused his position by accusing a mother of drugging and murdering her son.
The GMC found that Dr Southall's actions added to the distress of the mother - Mandy Morris, from Shropshire - whose 10-year-old son Lee hanged himself in 1996.
The hearing in December heard how Dr Southall made the claim in an interview with Mrs Morris about the safety of her surviving son.
The GMC also ruled Dr Southall had acted inappropriately in some cases by keeping original medical documents on children in his care separate from their medical records.
The GMC told the High Court that rules used to apply for Dr Southall's suspension were introduced in 2004.
As the allegations centred on events prior to 2004, the previous set of rules should have been applied, which would have meant the ban was not imposed.
The GMC said in a statement on Tuesday: "We can confirm that the immediate suspension imposed on Dr David Southall's registration has been lifted by mutual consent.
"The GMC supports the application to lift the immediate suspension, pending the outcome of the appeal against the panel's direction to erase Dr Southall's name from the medical register.
"Dr Southall's registration will be subject to previously imposed conditions which prevent him undertaking any child protection work."
Dr Southall said it was important for him to have the suspension overturned so he could work as a doctor for "humanitarian aid work abroad".
He added that he would be leaving his job at the hospital in Staffordshire from June.
In a separate case in 2004, he was suspended from child protection work over his role in the case of Sally Clark, wrongly jailed over the death of her two sons. Dr Southall had accused Mrs Clark's husband Steve of murdering the two boys on the basis of a television interview Mr Clark gave.
The doctor also faces another GMC disciplinary hearing into the so-called CNEP breathing tank experiments at the hospital in the 1990s.
The case is expected to start in Manchester next week and will look into the research carried out which involved placing premature babies into low-pressure incubators so they could breathe on their own.
