 One of the demands of the Kalisz faction in 1820, regarding independence of the judiciary, led the tsar Alexander I of Russia (who was also king of Congress Poland, the Russian Empire puppet state) to suspend the Polish parliament for a period of five years; Niemojowski was dismissed from the parliament before that and subject to house arrest for over a year.After the parliament was reestablished, he was a vocal opponent to the movement to make the parliament debates secret, and criticized the tsar's and Russian officials breaking the Constitution of the Congress Poland.In 1830 tsar ordered the Senate of Poland to annul Niemojowski's and his brother's mandates on a technicality in order to bar them from attending the parliament sessions.
