The case was taken by the NAGP, which opposes the government’s scheme.
It is understood that the NAGP withdrew the case following legal advice and because of possible cost implications.
“For families across Ireland, this is a positive development,” said the Minister for Health Leo Varadkar.
“Over 70 per cent of GPs have already signed up to provide free GP care, childhood health checks and asthma care to the under sixes.
“The withdrawal of this High Court case removes any remaining uncertainty and should, I hope, encourage remaining GPs to sign up.
“Of course, it remains a matter for individual GPs on whether they wish to take part in the scheme. I now look forward to engaging with GPs on a new core contract and further improvements to the scope and resourcing of primary care.”
