Are the court systems in England, Wales, Scotland, and Northern Ireland identical?

The legal landscape across the UK isn't a uniform field; it's more like a patchwork quilt, with each country having its own distinct legal system. England and Wales share a legal system, but Scotland and Northern Ireland each operate independently. This stems from the Acts of Union in 1707, which united England and Scotland, and subsequent historical developments. Scotland, for instance, retained its unique legal traditions, influenced by Roman and civil law, which differ significantly from the common law system used in England and Wales. Northern Ireland's legal system is based on common law principles but has its own distinct courts and legislation, reflecting its specific historical and political context. So, while there are overarching UK laws, the administration of justice and the specifics of legal proceedings vary considerably, making the idea of identical court systems a misconception.
Imagine a quartet playing different tunes—each country's court system plays to its own beat.
