On 18 January 2022, the Court of Appeal will hear the appeal of the Counsel General for Wales against the High Court’s refusal to grant permission to bring a judicial review of the United Kingdom Internal Market Act 2020 (UKIMA) on grounds of prematurity. As Lord Justice Singh stated when granting permission to appeal, ‘the case raises important issues of principle going to the constitutional relationship between the Senedd and the Parliament of the UK.’ The original claim sought advisory declarations that UKIMA must be read down to prevent the ambit of the Government of Wales Act 2006 – a constitutional piece of legislation which protects the devolved powers of the Senedd and Welsh Government –  from being cut down, either by implication or by secondary legislation.

Helen Mountfield QC and Mark Greaves are instructed by the Welsh Government Legal Services on behalf of the Counsel General.
