Question: Sovetskaya Litva found itself free at the same time as the fall of Supreme Soviet of the Lithuanian SSR, what change allowed both of the actions to happen?

<P0-S0> The Byelorussian Soviet Socialist Republic (BSSR, or Byelorussian SSR; Belarusian: Bielaruskaja Savieckaja Sacyjalistyčnaja Respublika or Bielaruskaja SSR , Russian: Belorusskaya Sovetskaya Sotsialisticheskaya Respublika or Belorusskaya SSR ), also referred to as the Soviet Byelorussia was a client state of the Soviet Union (USSR). <P0-S1>  It existed between 1920 and 1922, and from 1922 to 1991 as one of fifteen constituent republics of the USSR, with its own legislation from 1990 to 1991. <P0-S2>  To the west it bordered Poland. <P0-S3>  Within the Soviet Union, it bordered the Lithuanian SSR and the Latvian SSR to the north, the Russian SFSR to the east and the Ukrainian SSR to the south. <SEP> <P1-S0> The Supreme Soviet of the Lithuanian SSR (Lithuanian: "Lietuvos TSR Aukščiausioji Taryba" ; Russian: Верховный Совет Литовской ССР , "Verkhovnyy Sovet Litovskoy SSR") was the supreme soviet (main legislative institution) of the Lithuanian SSR, one of the republics comprising the Soviet Union. <P1-S1>  The Supreme Soviet was established in August 1940 when the People's Seimas declared itself the provisional Supreme Soviet. <P1-S2>  According to the constitution it was very similar to modern democratic parliaments: it was elected every four (later five) years and had the power to create, amend and ratify the constitution, laws, and treaties and appoint officials in the Council of Ministers (the executive branch). <P1-S3>  The political power shifted from CPL to the Soviet, which adopted a number of important constitutional amendments and laws, paving the way for the independence. <P1-S4>  However, in reality the elections were staged, the Soviet had very little actual power and carried out orders given by the Communist Party of Lithuania (CPL). <P1-S5>  The situation changed in 1988, when the Lithuanians began seeking independence from the Soviet Union. <P1-S6>  The first free elections were held in February 1990 and were won by pro-independence Sąjūdis. <P1-S7>  During its first session the Supreme Soviet adopted the Act of the Re-Establishment of the State of Lithuania and renamed itself the Supreme Council of the Republic of Lithuania. <SEP> <P2-S0>  After the restoration of Lithuania's independence in 1990, the newspaper became an independent daily under the name Echo Litvy (literally: "Echo of Lithuania"; Russian: Эхо Литвы ). <P2-S1> Sovetskaya Litva (literally: "Soviet Lithuania"; Russian: Советская Литва ) was a Russian-language daily newspaper published in the Lithuanian SSR. <P2-S2>  In tandem with the Lithuanian-language "Tiesa", it was the official newspaper of the Communist Party of Lithuania, the Supreme Soviet of the Lithuanian SSR, and the Council of Ministers of the Lithuanian SSR. <P2-S3>  Its circulation was 79,000 copies in 1981, 26,000 copies in 1993, and 12,000 copies in 1997. <P2-S4>  It discontinued publication in 2001 due to financial difficulties. <SEP> <P3-S0> The Lithuanian legislative elections for 141 seats in the Supreme Soviet of the Lithuanian SSR were held in the Lithuanian SSR on 24 February with run-off elections on 4, 7, 8 and 10 March 1990. <P3-S1>  In six constituencies voter turnout was below required minimum, therefore a third round was held on April 7 and 21. <P3-S2>  For the first time since the election to the People's Seimas in 1940, non-communist candidates were allowed to run. <P3-S3>  It was the first and the only free multi-party elections in Soviet Lithuania. <P3-S4>  Pro-independence Sąjūdis movement refused to become a political party and endorsed candidates of various other political parties based on their personal merits. <P3-S5>  These endorsements often meant more than official party affiliations, and Sąjūdis-backed candidates won 91 out of 135 seats. <P3-S6>  During its third session on 11 March 1990, the Supreme Soviet of the Lithuanian SSR adopted the Act of the Re-Establishment of the State of Lithuania thus declaring Lithuania's independence from the Soviet Union.
