but a clever case has recently been made by Powicke, who, minimizing the importance of the accepted argument from the silence of immediate contemporaries, argues, on the basis of the Annals of Margam, that there probably was a second condemnation in 1204. After all, the question is of subordinate importance, for Philip's effective action was based on the trial of 1202, and by John's fate was already sealed.
