Political activity
From the outset, the work of the Supreme Council on 11 March 1990, Lithuania adopted the Act of the Re-Establishment of the State of Lithuania. On March 12, the Supreme Council adopted Resolution, that declared USSR universal military service law of 12 October 1967, invalid within the Republic of Lithuania. The council also nationalized all the assets of the USSR, that were located in Lithuania. But just three days later, on 15 March, the Soviet Congress of People's Deputies adopted a resolution, in which restoration of the independence of the Republic of Lithuania was declared null and void. Congress passed this resolution with 1,463 people's deputies voted for, 98 voted against and 128 abstentions.

Economic blockade has suspended the country's economic growth and the foreign states would not recognize the independence of Lithuania. But on 6 September 1991, after failed 1991 Soviet coup d'état attempt, the Soviet federal government has officially recognised independence of Lithuania and other Baltic states, and lifted blockade.

In the first half of 1992, parliament's majority changed. Until the end of 1991, the United Sąjūdis parliamentary group held majority. Its members by late 1991 and early 1992 gradually switched to other parliamentary groups (e. g. Seventh/Moderates' parliamentary group). This led to the infighting between United Sąjūdis parliamentary group (along with Vagnorius-led government) and so-called the 'New Majority' (naujoji dauguma).

It caused gridlock in the parliament as both groups held their sessions separately or the United Sąjūdis parliamentary group boycotted official ones. On July 9, 1992, Supreme Council voted for the snap elections, which took place on October 25, 1992.
