The statutes of 1353, 1365, 1393 were attempts to prevent the referral of English court judgements to a foreign state - which in effect meant appeals to the papacy, thus invoking papal authority. Later Henry VIII would use them in his conflict with Cardinal Wolsey in 1529. [Lat. praemunio = safeguard, fortify, defend in advance]
