Three senior judges have ruled that Dominic Grieve, the attorney general, acted unlawfully when he blocked the publication of letters written by Prince Charles to government ministers.Leave has been granted to appeal to the Supreme Court, so release could still be overturned. But in the meantime, its an important victory of transparency over secrecy, and law over monarchical privilege.
The ruling, led by Lord Dyson, the head of the civil judiciary in England and Wales, paves the way for the release of the letters which reveal how the prince lobbied government ministers to change official policies.

Dyson, the master of the rolls, said Grieve "did not have reasonable grounds" for issuing the veto "merely because he disagrees with the decision" of the tribunal.
Grieve "could point to no error of law or fact in the [tribunal's] decision, and the government departments concerned did not even seek permission to appeal it", he added.
As for the wider issue: if the UK government is worried about the monarchy's political neutrality, maybe they should place the blame where it lies: on Charles Windsor. And start returning his letters unopened.
