(In third paragraph, corrects number of vehicles already exported to 20 from 10)
BERLIN, Dec 3 (Reuters) - A German court on Tuesday annulled a de facto export ban that had prevented arms manufacturer Rheinmetall from exporting armoured vehicles to Saudi Arabia, saying German authorities had not followed correct procedures.
In November last year, Germany imposed a ban on future arms sales to Saudi Arabia and temporarily halted deliveries of previously approved kit after Saudi journalist Jamal Khashoggi was murdered in Riyadh's diplomatic mission in Istanbul.
But the court ruled that authorities had failed to follow proper procedures in revoking a previously issued licence allowing the sale of 110 vehicles to Saudi Arabia, 20 of which had already been sent by the end of last October.
A legal source said the company in question was Rheinmetall.
The court said the manner in which the export licence had been revoked indicated that authorities were trying to avoid being forced to pay compensation. The German government can appeal the ruling.
The economy ministry, which is in charge of arms export licences, and Rheinmetall were not immediately available to comment.
