Laval's next conflict was with Dumesnil, an advocate of the Parliament of Paris, and the agent of the Company of New France. While in Paris, the bishop was instructed by the Government to choose a governor to his own liking. He selected Saffray de Mézy, of Caen, for the governorship, and with him he sailed for the colony, arriving on the 15th of September, 1663. Immediately on arriving, Laval and the Governor proceeded to construct the new Council. Virtually all the nominations were made by the bishop, who knew everybody, while the Governor knew absolutely no one in the whole country. The new Council formed, Dumesnil at once pressed the long pending claims of his company for settlement. The Council was composed of ignorant and corrupt men, several of whom were actually defaulters to the company represented by Dumesnil, and Laval was much blamed for placing them in an office which rendered them judges in their own cause. The Attorney-General demanded in Council that the papers of Dumesnil should be forcibly seized and sequestered. To this the Council at once agreed, and that night Dumesnil's house was entered and ransacked for the papers, which on being found were seized. The agent himself barely escaped with his life. He fled to France, and succeeded in gaining the ear of Colbert, the King's minister, who promptly moved in the matter.
Mézy, though he owed everything to the bishop, determined that he would be his mere instrument and tool no longer. The old war between Church and State broke out again. Mézy was a bigot, who stood in mortal terror of the power of the Church, and whose whole life was made up of the veriest superstition, but he rebelled against Laval. Discovering that the Council was composed of creatures of the bishop, he, on the 13th of February, 1664, ordered three of the most notorious members to absent themselves from the Council. At the same time he wrote to the bishop and informed him of what he had done, and asked him to acquiesce in the expulsion of his favourites. Of course Laval refused to do anything of the kind. Mézy then caused his declaration to be announced to the people in the usual way, by means of placards posted about the city, and by sound of the drum. The bishop, however, had the best of the encounter. Mézy learned to his horror and consternation that the churches were to be closed against him, and that the sacraments would be refused him. In his despair he sought counsel from the Jesuits, but the comfort which he received from them was to follow the advice of his confessor--also a Jesuit. In the meantime Laval had become unpopular through a tithe which he had caused to be imposed, and the people were clamouring for a settlement of the difficulty. Mézy called a public meeting, appointed a new Attorney-General, and declared the old one excluded from all public functions whatever, pending the King's pleasure in the matter. All through this conflict of authority, the sympathy of the people was with the Governor, though the latter was denounced from the pulpits. Mézy appealed to the populace for justice, and by this act signed the warrant of his own doom. Laval reported the circumstance to the King, and the Governor was peremptorily recalled.
