A landmark ruling which ordered the Netherlands to stop delivering parts for F-35 fighter jets used by Israel in Gaza should be upheld, the Dutch highest court has been told, AFP reports.

The advice by Supreme Court Advocate-General Paul Vlas comes after an appeals court in February ordered the Dutch state to “put an end to further export of F-35 parts to Israel”.

“The Hague Appeals Court ruling that the Dutch State must put an end to the export of F-35 parts to Israel can remain in place,” Vlas advised the Supreme Court’s judges.

Vlas’ assessment was “based on various international regulations to which the Netherlands is a party, (and) the export of military goods must be prohibited if there is such a clear risk” of breaking them, the Hague-based Supreme Court said in a statement.
