In its corporate capacity the chapter takes charge sede vacante of a diocese. In England, however (except as regards Salisbury and Durham),[8] this custom has never obtained, the two archbishops having, from time immemorial, taken charge of the vacant dioceses in their respective provinces. When, however, either of the sees of Canterbury or York is vacant the chapters of those churches take charge, not only of the diocese, but of the province as well, and incidentally, therefore, of any of the dioceses of the province that may be vacant at the same time.
