 The number of the members was not fixed ; it varied from over 200 ( with 289 in 1782 and 213 in 1817 ) to as low as 41 ( in 1834 ) ; in most years the Sejm had averaged 60 to 80 deputies . They were composed of clergy , nobility ( either titled or above a certain , relatively high , income level ) , two deputies from the city of Lviv representing the burghers and later , chancellor of the University of Lwów . The members were not elective , holding the mandates due to their offices , titles or wealth . This made the Sejm not representative , and rather conservative .
