Jim Matthews, a British national who had been assisting the Kurdish population in Rojava against the Islamic State was acquitted in Britain of terrorism-related charges.

Matthews was arrested two years and five months ago after returning to London. He had been assisting Kurds and Western Coalition Forces in Rojava against the onslaught of ISIS.

As his lawyers at Birnberg Peirce Solicitors recalled, Matthews was accused of attending "a terrorist training camp organised by the YPG, an entirely lawful Kurdish organisation".

After two years the Crown Prosecution Service decided that there was sufficient evidence to prosecute him and that it was in the public interest to do so.

Seven months later, said his lawyers, they "now say they have discovered new evidence that led them to drop the case". This new evidence, though, has not been disclosed.

While clearly satisfied with the acquittal decision, Matthews' lawyers said that their client is entitled to a full explanation of what happened.  "As the High Court Judge hearing the case has indicated that it is now a matter for the Attorney General to explain to Parliament, we urged him to do so as soon as possible", said the lawyers.

Indeed the lawyers have argued throughout the case that in fact "there was never a credible case of terrorism to be made against Mr. Matthews, either factually, morally or legally".

Furthermore "when Matthews was arrested the YPG was a politically necessary ally of the UK", added the lawyers who explained that things changed in light of Turkey "being an important market for British arms sales". Thus the lawyers asked: "Was this the reason the Attorney General decided that an otherwise implausible prosecution be brought?"

After the stress and anxiety of two years waiting followed by seven months on bail, and several court appearances, said the lawyers "Jim Matthews is entitled to an answer".
