A BUSINESS expert who was detained during a doomed Rangers fraud probe is planning to take his multi-million-pound compensation claim to Britain’s highest court.

David Grier, 60, told on Wednesday of how he is instructing his lawyers to go to the UK Supreme Court to continue his long-running legal battle against Scottish prosecutors. 

He is seeking compensation from the Lord Advocate Dorothy Bain KC because he believes the prosecution against him was malicious and has damaged his ability to make a living. 

On Wednesday, his advocate Roddy Dunlop KC failed to persuade appeal judges at Edinburgh’s Court of Session to grant him permission to proceed to the Supreme Court. 

However, Mr Grier’s lawyers plan to approach the UK Supreme Court directly in the next few months. 

Mr Grier, who comes from Barrhead, Renfrewshire, said: “I’m unfortunately not surprised that the Inner House have refused to allow us to appeal to the Supreme Court.

“However, we do intend to take the matter directly to the Supreme Court.” 

The Court of Session has previously heard how Mr Grier was taken into custody during an investigation into alleged criminal wrongdoing at the club. 

Detectives and prosecutors believed that the law had been broken during the time the club was sold to businessman Craig Whyte. 

Prosecutors claimed that Mr Grier participated in a fraud with Mr Whyte. They claimed that Mr Whyte broke the law by using cash from a firm called Ticketus to acquire the finance to buy Rangers. 

Mr Grier was prosecuted alongside other men who were said to be involved in the alleged wrongdoing. However, everybody arrested during the probe was acquitted of any wrongdoing. 

This prompted Mr Grier to launch a £7 million compensation action against the police and Crown Office, claiming his arrest had affected his ability to maintain his job in financial services. 

Prosecutors previously admitted David Whitehouse and Paul Clark were wrongfully arrested and prosecuted - and the two men settled their action with both the Crown Office and Police Scotland with each of them receiving £10.3 million each - their legal bills, thought to be worth £3 million each, were also paid for.

Mr Grier's lawyers told judge Lord Tyre at the Court of Session that both law enforcement agencies had acted maliciously against him, entitling him to compensation. 

Lord Tyre also heard claims that the police officer leading the investigation - Detective Chief Inspector Jim Robertson - had acted inappropriately during the investigation. 

Nevertheless, Lord Tyre ruled that Mr Grier’s lawyers hadn’t shown that the prosecution service had acted maliciously. 

However, he said some of DCI Robertson’s evidence was “evasive” and “unreliable” and that some of his actions during the probe were “reprehensible”.

This prompted lawyers for Mr Grier to appeal to the Inner House of the Court of Session. 

On Wednesday,  Mr Grier’s lawyer Roddy Dunlop KC told civil appeal judges that the legal tests needed for the Court of Session to allow cases to go to the Supreme Court had been passed. 

He told Lord Carloway Lord Pentland and Lord Woolman: “There is a genuine need for someone who has been caught up in such a scandal to have effective public remedy. 

“There are good grounds available in this case to allow it to proceed.”

The Lord Advocate’s lawyer Gerry Moynihan KC said that he disagreed that the legal tests needed had been passed.

He added: “The question is whether there was an ulterior motive in prosecuting Mr Grier. The answer is that there is none. The prosecution was conducted in the reasonable belief that there was a reasonable belief that there was evidence available. 

“Your lordships should not grant permission to proceed.”

Lord Carloway and his colleagues concluded that the tests needed for the case to proceed to the UK Supreme Court had not been passed.
