Dutch judges yesterday gave the green light for a teenage girl's bid to become the youngest person to sail around the world solo, thwarting a bid to have her kept in child care.

"The court rejects the request for the extension of supervision of child care authorities over 14-year-old Laura Dekker," judge Suzanne Kuypers said in the Middelburg district court.

"The supervision of the child is lifted with immediate effect."

Child care authorities asked the court last week to extend Dekker's supervision by 12 months to August 2011 in a bid to stop her departure, citing fears for her social and emotional wellbeing.

Dekker, who has the backing of her parents, needs to complete the two-year trip before she turns 17 on September 20, 2012, to set the new record.

The dutch girl, who was not present for the judgment, hopes to set sail within the next two weeks.

Judge Kuypers said the verdict "puts the responsibility for the child back where it belongs: with the parents".

In May, Australia's Jessica Watson became the youngest person at 16 to sail around the world non-stop, solo and unassisted.
