To the common petition of the Welsh of north Wales that they should be able to buy and sell lands in Wales: this would be a change in the law of those parts since none of them could sell land or let it for a term, except for a term of four years. And although they say that the king granted this article, it does not appear to the prince nor to his council that it was granted to them by the king, since those things granted to them by the king are expressly contained in his grant made to them, namely in the Statute of Rhuddlan, in which no mention was made of that article,nor does the prince intend to change the law in this case [which was] by decree of the king himself, because the king handed that land over to him to hold to himself and his heirs of the kings of England.
