A Medical Council fitness-to-practise committee has found Dr Sabah Al-Zayyat guilty of professional misconduct on one count.
It found that she failed to inform Tallaght Hospital that conditions had been attached to her registration by the UK's General Medical Council when she applied for a post in November 2008.
The GMC interim conditions were attached to Dr Al-Zayyat in the public interest, arising from her examination of a 17-month-old child in Britain on 1 August 2007, who died two days later in a controversy known as the 'Baby P' case.
Dr Al-Zayyat of Brookfield, Mullingar, Co Westmeath and an address in Essex, England, failed to attend today's hearing and was not legally represented.
Barrister Ronan Kennedy, for the council, told the inquiry that Dr Al-Zayyat was registered in Ireland with the Medical Council in July 2002 and worked in Ireland up to 2006.
She worked at St Anne's Hospital in London in 2007-2008.
On 9 November 2008, she applied to Tallaght Hospital for a post as a part-time locum consultant paediatrician with a special interest in community child health.
Today's inquiry heard she failed to notify Tallaght Hospital of the conditions on her practice when she applied online.
The GMC in the UK attached interim conditions to Dr Al-Zayyat's continued practice from 11 August 2008 to 21 November 2008.
She was required to notify the GMC if she applied for any job outside the UK and to notify any prospective employer of the conditions and restrictions on her practice.
It followed her examination of 'Baby P' in Britain on 1 August 2007, a child on the child protection register, who had unexplained injuries.
Peter Connolly was found dead at home two days after the examination.
He had significant injuries, including a broken back and had suffered child abuse.
He was referred to as 'Baby P' in investigations into his death.
Subsequently, a number of individuals were found guilty of causing or allowing his death and were imprisoned.
The GMC decided that risks were posed by Dr Al-Zayyat's continued unrestricted practice.
Today's inquiry heard that on 11 February 2011, the GMC granted voluntary erasure from the register to Dr Al-Zayyat.
Mr Kennedy told the inquiry today that the Medical Council has been unable to contact Dr Al-Zayyat, despite extensive efforts.
In a statement, Tallaght Hospital said that Dr Al-Zayyat had worked there, through an agency, on a number of occasions between 2002 and 2006.
It said that, as is standard practice for the use of agency staff, all appropriate due diligence was undertaken.
In addition, no issues have been raised regarding the care she provided while working in Tallaght Hospital.
It said she applied for a post in 2008, but disqualifying information relating to the conditions of her registration in the UK was identified as part of the hospital's robust vetting procedures.
