A Dubai court on 12 September refused Denmark's request to extradite British hedge fund trader Sanjay Shah over an alleged $1.7bn tax scheme fraud.

The court requested on 9 September that authorities submit the necessary documentation for the extradition, according to a report in The National

Danish officials had signed an agreement in March this year allowing for extradition between the United Arab Emirates and Denmark.

In a statement on 3 June, Dubai police Brigadier General Jamal al-Jallaf had said that the emirate received an international arrest warrant from Denmark for Shah, who is accused of a fraud that saw foreign businesses pretend to own shares in Danish companies and claim tax refunds for which they were not eligible.

"The fraud scheme, known as ‘cum-ex' trading, involved submitting thousands of applications to the Danish Treasury on behalf of investors and companies from several countries around the world in order to receive dividend tax refunds," al-Jallaf had said.

In the latest court ruling on Monday 12 September, The National reported that senior judge Rashid Al Smairi  said according to article (11) of the Law on International Judicial Co-operation, original copies of all official investigations carried out must be attached to the extradition request.

He said the copies must include records of witnesses' testimonies signed by them and by police officers, details of the arrest, inspections and other evidence, such as accounting and technical reports related to proving the accusation against the person, The National said. 

The case is open to appeal but lawyer Ali Al Zarouni, representing Shah, told The National he believed it was unlikely Danish authorities will be successful.
