The council's fitness to practise committee said it was satisfied Dr Ragheb Nouman had provided information he knew to be untrue while filling out an online application form in February 2018 to register as a doctor in Ireland.
An inquiry last month heard how Dr Nouman had told the Irish Medical Council (IMC) he had never been subject to any disciplinary proceedings or complaints by another medical regulatory authority.
His application form to the IMC indicated he had never been struck off or suspended from acting as a doctor.
Committee chairperson Paul Harkin said Dr Nouman had deliberately failed to provide full, true and accurate information to the IMC. "The committee is satisfied that Dr Nouman's conduct was profoundly dishonest and that his excuses are not believable and his evidence was not credible," Mr Harkin said.
The committee said Dr Nouman's conduct was "disgraceful and dishonourable" and fell seriously short of the standards expected from doctors.
Dr Nouman (58) worked at seven hospitals here between September 2018 and April 2019 before the IMC learned he had been banned from practising as a doctor in the UK. He was suspended from practising in Ireland in May 2019.
Concern was first raised about Dr Nouman, who qualified as a doctor in Romania in 1991, when a staff member at Our Lady's Hospital, Navan, saw information about his disqualification in the UK online.
The Syrian-born medic had worked as a locum senior house officer for short periods at University Hospital Mayo, Castlebar; Connolly Hospital, Blanchardstown; Our Lady of Lourdes Hospital, Drogheda; South Tipperary General Hospital, Clonmel; Wexford General Hospital; University Hospital Galway; and Our Lady's Hospital, Navan.
Dr Nouman claimed he had made "an innocent mistake" as he found the application form complex and tiring as a foreign doctor and had forgotten what happened in the UK.
He was struck off in the UK in January 2016 after an inquiry found his clinical work "unacceptable" and that he had made racist comments about Indian people.
During the IMC inquiry, he stressed he was not a racist and there had been no complaints about his clinical work at Irish hospitals.
