Convicted criminals could walk free under a new ruling by the Law Lords, a Birmingham defence solicitor has said.
But Nicholas Roy, a partner at Corporation Street-based Jonas Roy Bloom, said the decision was vital for the fair course of justice.
Mr Roy represents Nathan Martin, one of the four men convicted of killing Birmingham students Charlene Ellis and Letisha Shakespeare in 2003.
At least two of the men jailed for the murders will be appealing their decisions after five law lords, on Wednesday, overturned the verdict against a London man accused of a double murder because witnesses gave evidence anonymously.
The trial of the alleged killers of Charlene and Letisha was the first time witnesses had been allowed to stay anonymous for their own protection.
The Government has signalled that it was prepared to change the law following the House of Lords’ ruling which Mr Roy said was likely to lead to more appeals from convicted criminals in cases where witnesses were protected because of the risk of violence.
He said: “It may ensure that guilty people are acquitted, that I accept.
“I would have thought that anyone who has been convicted of an offence with the use of anonymous witnesses may very well want to appeal.”
The four men convicted of killing Charlene and Letisha are Martin (26), of South Road, Smethwick (pictured); Marcus Ellis (24), of Devonshire Avenue, Winson Green; Michael Gregory, (23), of Ryland Street, Ladywood; and Rodrigo Simms (20), of Whitehouse Drive, Smethwick.
Errol Robinson, the solicitor representing Ellis and Simms, said he would be lodging an application in the next few days to the Criminal Cases Review Commission asking for their cases to be referred for appeal.
Mr Robinson said he was pleased to see Law Lords recognise a position that he had always held over the conviction of his clients.
He said he had appealed twice before, unsuccessfully, on the grounds that the trial was unfair because an anonymous witness had been used.
Mr Roy said he had not received any instructions from Martin, but if asked he would advise his client to try for an appeal.
The solicitor, a former member of the Birmingham Law Society, represented Tafarwa Beckford, who was also accused of the murder of Charlene and Letisha, after the shootings.
Beckford, the step-brother of R&B singer Jamelia, was cleared of all charges.
