was to send a delegation to Saint Petersburg, petitioning Catherine to guarantee the liberties of the Republic, and allow the proper legislation to be settled by the Russian ambassador at Warsaw. With Russian troops sent to "protect" the various pro-Russian factions and this carte blanche in his pocket, Repnin proceeded to treat the deputies of the Sejm as if they were already servants of the Russian empress. The opposition was headed by four bishops: Bishop of Lwów Wacław Hieronim Sierakowski (1699–1784), Bishop of Chełm Feliks Turski (1729–1800), Bishop of Cracow Kajetan Sołtyk (1715–1788), and Bishop of Kiev Józef Andrzej Załuski (1702–1774). To break the opposition, Repnin ordered the arrest of four vocal opponents of his policies in the Polish capital, namely bishops Józef Andrzej Załuski and Kajetan Sołtyk and hetman Wacław Rzewuski with his son Seweryn. All of them members of the Senate of Poland, they were arrested by Russian troops on October 13, 1767 and imprisoned in Kaluga for 5 years. Through the Polish nobles that he bribed (like Gabriel Podoski, Primate of Poland) or threatened by the presence of over 10,000 Russian soldiers in Warsaw and even in the very chambers of the parliament, Repnin, despite some misgivings about the methods he was ordered to employ, de facto dictated the terms of that Sejm. The intimidated Sejm, which met in October 1767 and adjourned till February 1768, appointed a commission (the so-called Delegated Sejm) which drafted a Polish–Russian treaty, approved in a "silent session" (without debate) on February 27, 1768. The legislation undid some of the reforms of 1764 under King Poniatowski and pushed through legislation which ensured that the political system of the Commonwealth would be ineffective and easily controlled by its foreign neighbours. The liberum veto, wolna elekcja (free election), neminem captivabimus, rights to form the confederation and rokosz — in other words, all the important privileges of the Golden Liberty, which made the Commonwealth so ungovernable — were guaranteed as unalterable parts in the Cardinal Laws. The Sejm, however, also passed some more beneficial reforms. Russia, which had used the pretext of increased religious freedoms for the Protestant and Orthodox Christians to destabilize the Commonwealth in the first place, now had to push those reforms through the Sejm to save face. Thus, the legislation of the Sejm granted those religious minorities the same status as that of the previously dominant Roman Catholics, and some privileges
