It was not until later in 1906, with the revolution in retreat, that the Kadets abandoned revolutionary and republican aspirations and declared their support for a constitutional monarchy. The government remained suspicious of the Kadets until the fall of the monarchy in 1917. Finnish liberal politician and professor of jurisdiction and politology Leo Mechelin was expelled 1903–1904 when the Kadets were preparing to form a party. Mechelin cooperated with them and wrote them a liberal constitution for Russia to be enforced when they would get into power. At the time of Vyborg Manifesto, Mechelin was already the leader of the Finnish government, or "Mechelin's senate" (1905–1908), which implemented the universal right to vote and freedoms of expression, press, congregation and association.
