Sima Radulović

In 2000, the GSS joined the Democratic Opposition of Serbia (Demokratska opozicija Srbije, DOS), a broad and ideologically diverse coalition of parties opposed to Slobodan Milošević's administration. Milošević was defeated by DOS candidate Vojislav Koštunica in the 2000 Yugoslavian presidential election, a watershed moment in Serbian politics. In the concurrent 2000 Serbian local elections, Radulović won election to the City Assembly of Niš as a DOS/GSS candidate in the twenty-fifth division.^[2] The DOS parties won a landslide victory in city and afterwards formed a new coalition government. The GSS took part in the administration, and Radulović was appointed as a vice-president of the city's executive board, initially with responsibility for economy and finance and later with responsibility for civil administration reform.^[3][4]

Following Milošević's defeat in the Yugoslavian election, a transitional government was established in Serbia and a new Serbian parliamentary election was called for December 2000. Radulović received the seventy-first position on the DOS's electoral list and was awarded a mandate after the coalition won a landslide victory with 176 out of 250 mandates.^[5] (From 2000 to 2011, all mandates in Serbian parliamentary elections were distributed to candidates on successful lists at the discretion of the sponsoring parties or coalitions, irrespective of numerical order. Radulović did not automatically receive a mandate by virtue of his list position, though he was included in the GSS delegation all the same.)^[6] He took his seat when the assembly convened in January 2001 and served as a government supporter.^[7]

In July 2003, Radulović was appointed as a parliamentary delegate to Serbia's lustration commission, which was to review the responsibility of individuals in human rights violations starting from 23 March 1976, when the International Covenant on Civil and Political Rights came into effect.^[8] He was later chosen as president of the body, although his appointment ended when his parliamentary term expired. In standing down from the committee, he complained that its work had not begun and that it seemed likely the country's incoming government would abandon it entirely.^[9]

The GSS contested the 2003 Serbian parliamentary election on the electoral list of the Democratic Party (Demokratska stranka, DS), and Radulović was included in the 221st position.^[10] The list won thirty-seven mandates, and he was not included in the GSS's delegation afterwards.^[11] His term in the assembly ended in early 2004.

The GSS board in Niš subsequently became divided into rival camps. Radulović resigned from the presidency of the board in March 2003 and also stood down from his role as a party representative in the city's administration.^[12] He later withdrew from the party entirely and started an independent political movement called the "League for Niš."^[13][14]

Serbia introduced the direct election of mayors in the 2004 Serbian local elections. Radulović ran for mayor of Niš under the banner of the "League for Niš" and finished last in a field of nine candidates. He later rejoined the GSS after a change in its leadership and served on the party's presidency.^[15] The GSS contested the 2007 Serbian parliamentary election on the list of the Liberal Democratic Party (Liberalno demokratska partija, LDP); Radulović appeared in the 185th position and did not receive a new mandate after the list won fifteen seats.^[16] He appears to have withdrawn from political life after this time.
