What is Welsh law? Wales has shared a legal system (being the legislature, laws and the jurisdiction of courts to enforce those laws) with England for nearly 500 years. The concept of ‘Welsh law’ as separate from the law of England and Wales is a relatively recent development. The 1997 devolution referendum led to the Government of Wales Act 1998 (GWA 1998), which created a National Assembly for Wales (subsequently renamed the Welsh Parliament or Senedd Cymru, and known since May 2020 as the Senedd), which initially exercised both parliamentary and executive functions. By virtue of the Government of Wales Act 2006 (GWA 2006), the Senedd retains the parliamentary function and the executive function was transferred to the Welsh Assembly Government (subsequently renamed the Welsh Government). The Senedd’s powers were further enhanced by the Wales Act 2017 and it now enjoys the power to pass legislation (Acts of Senedd Cymru) as it applies in relation to Wales across 20 devolved areas including agriculture, economic development, education, environment, food, health, housing,
