PARIS (Reuters) - France's highest administrative court said on Wednesday it had awarded 15,000 euros ($16,320) in damages to a family after border police failed to stop their teenage daughter from boarding a plane to Turkey before traveling to Syria.
The girl, who was aged 17 at the time, had been put on an internal watchlist after fleeing home in June 2013.
Despite being sought, officials at Paris' second-largest airport let her embark on a plane for Istanbul in November even though French law prevents minors leaving the country without parental approval.
"The Council of State recognizes that the negligence of the police services was an error that establishes the liability of the State," a statement from the court said.
"There is no particular reason to justify a loosening of surveillance for the departure of minors from the territory and there is no sign that Mademoiselle K (the minor) used any methods to trick the police."
The statement said the girl had reached Syria, but did not say whether she had joined Islamist militants or whether she had now returned to France.
