Campaigners trying to prevent services being scaled back at a North Yorkshire hospital say they've had to abandon plans to take legal action.
Leaders at Richmondshire Council say they've been advised by legal experts not to challenge a decision - which will reduce maternity and children's services at the Friarage hospital in Northallerton.
Doctors who are part of The Hambleton, Richmondshire and Whitby Clinical Commissioning Group (CCG) have said the plans will make care at the hospital much safer and more sustainable.
Campaigners had fought against the changes for three years.
A hospital trust has apologised to the family of a seven-year-old boy who has received a £12m compensation payout. Toby Hart will need 24-hour care for the rest of his life after staff at the Friarage Hospital in Northallerton failed to spot he had an abnormal heartbeat when he was born.
South Tees NHS Foundation Trust said:
“We are sorry that the care afforded to Mrs Hart and to Toby fell below an acceptable standard and that Toby suffered very substantial injuries as a result.
"We have apologised for the failings and that apology is repeated together with every good wish to Toby and his family.
The trust acknowledges that no amount of money can compensate adequately for the damage suffered but it is hoped at least that the agreed sum will give some financial security and provide for Toby's needs."

The hospital has apologised to the Hart family.
Callous burglars injured lambs and a horse at stables in Northallerton.
It happened between 10 am on Tuesday June 9 and Wednesday June 10 at the premises on Castle Hills in Springwell Lane.
The burglars fed something to lambs which caused them discomfort and daubed them with blue paint. The intruders also seem to have tried putting a saddle on a horse, causing an injury to its mouth.
It is not known if anything was stolen during the burglary.
"Whoever broke into this stables has left the animals suffering in pain. They need to understand the consequences of their actions and the distress they have caused.
“I need to speak to anyone who has information which could help to identify those responsible for these acts of cruelty and urge them to contact the police straight away.
“Due to the location of the stables in the Castle Hills, it is possible the offenders approached them along Springwell Lane or from Romanby. If you were in the area at the time when the animals were injured, I ask you to contact the police immediately.”
