Bahrain is to retry in a civilian court a group of 20 medical staff found guilty in a military trial after unrest earlier this year.
The convictions drew criticism on human right grounds.
"The Public Prosecutor announced today that a new trial has been ordered for a group of 20 medical staff ... found guilty in initial trials in the National Safety Court," said a statement from the Gulf Arab state's Information Affairs Authority.
Bahrain jailed the 20 doctors last Friday, including six associated with the Royal College of Surgeons in Ireland, on charges relating to unrest in the Gulf kingdom.
The doctors were sentenced to between five and 15 years on charges of stealing medicine, stockpiling weapons and occupying a hospital.
The verdict was met with outrage by campaigners for the Irish-trained doctors.
It has been reported that the announcement of a civilian trial effectively nullifies last week's verdict.
RCSI-trained doctors, Dr Ali al-Ekri, Dr Bassam Dhaif, and Dr Ghassan Dhaif received 15-year sentences.
Dr Zahra al-Sammak, who also trained in Dublin, Dr Fatima Haji, who was a lecturer at the RCSI campus in Bahrain, and Rola al-Saffar, president of the Bahrain nursing society, received five-year sentences for allegedly being involved in the riots.
