Mixed Jurisdictions and Convergence: Scotland

There is an independent Scottish legal system today because, until the Union of the English and Scottish Crowns in 1603 and the Union of the Parliaments of the two countries in 1707, Scotland was an independent sovereign state. When King James VI of Scotland became James I of England and Great Britain in 1603, there was considerable interest in the possibility of establishing a single legal system for the newly united kingdoms, while during the Cromwellian interlude of the 1650s the possibility moved some way towards actuality. But the 1707 Act of Union showed a recognition that the establishment of a single legal system and body of law for the whole of the United Kingdom was not really a practical proposition, in articles which remain the formal basis for the continuing existence and independence of the Scottish law and legal system. Article XVIII provided for the continuation of Scots law after the Union, excepting only the ‘Laws concerning Regulation of Trade, Customs and … Excises', which were to ‘be the same in Scotland, from and after the Union, as in England.’ Change to Scots law was allowed under the Article, but in matters of ‘private right’ such change had to be for the ‘evident utility’ of the Scottish people. Only in matters of ‘public right’ might the aim be simply to make the law the same throughout the United Kingdom. Article XIX laid down that the principal Scottish courts, the Court of Session and the High Court of Justiciary, should ‘remain in all time coming’ as they were then constituted, and further provided that Scottish cases were not to be dealt with by the English courts ‘in Westminster-hall’ (which likewise continued to exist post-Union).
