The High Court has approved a settlement of €850,000 in the case of a woman with cerebral palsy over the circumstances of her birth 46 years ago.
The woman's solicitor said the case was unusual as it is believed to be the first medical negligence case to deal with events from 46 years ago.
Paula Corcoran, from Sligo town, had through her late father Malachy Corcoran sued the Health Service Executive over the circumstances of her birth at Galway Regional Hospital - now University College Hospital, Galway on 8 April 1976.
The settlement against the HSE was made without admission of liability.
Solicitor David O'Malley on behalf of the family said they were delighted with the settlement and had thanked legal representatives from both sides for using mediation to bring a conclusion to a complex case.
Mr O'Malley said: "Justice delayed is still justice".
The court was told by barrister Alistair Rutherdale that proceedings were brought in the case in 2014, when Paula was 38 years of age.
In the action it was claimed that Emily Corcoran had been admitted to the hospital on 7 April, 1976 and had been advised the baby was in an abnormal position.
She went into labour overnight and Paula was delivered by emergency caesarean section but required resuscitation.
It was alleged there was a failure to adopt a clear plan for active or expectant management on admission and a failure to maintain vigilant supervision through labour.
It was also claimed there was a failure to carefully assess and reassess the situation when labour started spontaneously.
All the claims were denied.
Approving the settlement, Mr Justice Garrett Simons said it was the Corcoran case that the position the baby was lying in before birth should have been given particular attention and there allegedly should have been one to one monitoring and earlier intervention.
The judge said the case had to be viewed from the medical practice standards of the time.
He said the defence were denying all claims and contended that the birth was carefully monitored and proper due care and attention was given to the mother and baby.
The HSE had also raised the issue of the delay in bringing the proceedings and a motion to strike out the case on the grounds of delay had been part heard by the courts.
The judge said the €850,000 settlement figure represented half the notional full value of the case.
He noted the exceptional care Paula's family had given her throughout the years and said they had made an excellent contribution, adding that she was "very, very lucky".
