The convening, opening, concluding, postponing, prolonging, and dissolving of the Assembly were prerogatives of the Prince (or King). Sessions were opened by the Prince's (or King's) speech, responded to by the Assembly with the address. Voting was either individual (by name) i.e. by deputy sitting or standing, or by secret ballot.
