No... "...A part of Magna Carta originally applied to Wales, as it specified "English law shall apply to holdings of land in England, Welsh law to those in Wales, and the law of the Marches to those in the Marches." This was dropped in the 1297 version.
However, Magna Carta never applied in Scotland, and the writ of habeas corpus, which was standardised in England under the Habeas Corpus Act of 1679, has no meaning in Scotland. It was not until 1887 that the Criminal Procedure Scotland Act introduced the equivalent requirements for a prompt trial. Ireland had its own Habeas Corpus Act in 1782."
