Liam Óg Ó hAnnaidh, also known by his stage name “Mo Chara”, appeared before Westminster Magistrates’ Court last September to face charges relating to a Kneecap concert in London in November 2024.

Mr Ó hAnnaidh was accused of breaching sections 13(1)(b) and (3) of the Terrorism Act 2000 by allegedly displaying the flag of Hezbollah, a proscribed organisation in the UK since 2019.

However, the case collapsed after Judge Paul Goldspring said the proceedings were not instituted in line with statutory requirements — missing a six-month time limit by a single day.

Mr Óg Ó hAnnaidh’s solicitor Darragh Mackin, partner at Belfast firm Phoenix Law, hailed the outcome as a victory for freedom of expression.

The Crown Prosecution Service (CPS) announced in October 2025 that it would appeal the decision “as we believe there is an important point of law which needs to be clarified”.

In a social media post, Kneecap said the appeal would be heard in the Royal Courts of Justice on Wednesday 14 January.

“It is the view of our legal team that there is not an iota of logic for this [appeal], it is without any sound legal basis,” Kneecap added.

“It is another flailing arm to distract from, and to try and silence those who stand on the right side of history as they are complicit.

“As Israel today moves to ban charitable organisations providing lifesaving aid and primitive shelter to millions, the British state once again turns to vilify those who oppose genocide.”
