 These two grants removed powers from the exercise of the bishop of the diocese and placed them in the hands of the Chapter.The Chapter had a set of Statutes, which were last codified in 1539 and remained in force down into the end of the 18th century.According to these statutes, a Canon might take leave of his Chapter duties for as long as three months per year, without having to have an explanation, so long as the time was not consecutive and a substitute priest or chorister was provided by the Canon so that his duties were carried out.
