The Cardinal Laws, a quasi-constitution endorsing most of the conservative laws responsible for the inefficient functioning of the Commonwealth, were confirmed and guaranteed by the partitioning powers. The Sejm also continued enacting laws reducing religious tolerance in the Commonwealth. The passive electoral rights of the Orthodox, Eastern Catholics and Protestants were diminished, with a restriction limiting the number of non-Roman Catholic Sejm deputies to three (one from Greater Poland, one from Lesser Poland, and one from the Grand Duchy of Lithuania). They were also banned from election to the Senate or ministerial positions.
