Here is the account as it appears in the Catholic Encyclopedia:
In 1075 St. Bruno was appointed chancellor of the church ofReims, and had then to give himself especially to the administration of the diocese. Meanwhile the pious Bishop Gervais, friend of St. Bruno, had been succeeded by Manasses de Gournai, who quickly became odious for his impiety and violence. The chancellor and two other canons were commissioned to bear to the papal legate, Hugh of Die, the complaints of the indignant clergy, and at the Council of Autun, 1077, they obtained the suspension of the unworthy prelate. The latter's reply was to raze the houses of his accusers, confiscate their goods, sell their benefices, and appeal to the pope. Bruno then absented himself from Reims for a while, and went probably to Rome to defend the justice of his cause. It was only in 1080 that a definite sentence, confirmed by a rising of the people, compelled Manasses to withdraw and take refuge with the Emperor Henry IV.
Pretty amazing to see that the process and problems haven't changed much in the 900 plus years since this account.
