The desire of the Burgundian princes to consolidate their dominions into a unified sovereignty found itself thwarted by many obstacles and especially by the lack of any supreme tribunal of appeal. It was galling to them that the _Parlement_ of Paris should still exercise appellate jurisdiction in Crown-Flanders and Artois, and the Imperial Diet in some of the other provinces. Already in 1428 Philip had erected the Court of Holland at the Hague to exercise large powers of jurisdiction and financial control in the provinces of Holland and Zeeland; and in 1473 Charles the Bold set up at Mechlin the body known as the Great Council, to act as a court of appeal from the provincial courts. It was to be, in the Netherlands, what the _Parlement_ of Paris was in France. The Great Council, which had grown out of the Privy Council attached to the person of the prince, and which under the direction of the Chancellor of Burgundy administered the affairs of the government, more particularly justice and finance, was in 1473, as stated above, re-constituted as a Court of Appeal in legal matters, a new Chamber of Accounts being at the same time created to deal with finance. These efforts at centralisation of authority were undoubtedly for the good of the country as a whole, but such was the intensity of provincial jealousy and particularism that they were bitterly resented and opposed. In order to strengthen the sovereign's influence in the towns, and to lessen the power of the Gilds, Philip established in Holland, and so far as he could elsewhere, what were called "vaste Colleges" or fixed committees of notables, to which were entrusted the election of the town officials and the municipal administration. These bodies were composed of a number of the richest and most influential burghers, who were styled the Twenty-four, the Forty, the Sixty or the Eighty, according to the number fixed for any particular town. These men were appointed for life and their successors were chosen by co-option, so that the town corporations gradually became closed hereditary aristocracies, and the mass of the citizens were deprived of all voice in their own affairs. The _Schout_ or chief judge was chosen directly by the sovereign or his stadholder, who also nominated the _Schepens_ or sheriffs from a list containing a double number, which was submitted to him.
