Member of the Belgrade city assembly (1997–2004)

The DS contested the 1996 Serbian local elections as part of the Together (Zajedno) coalition with the Serbian Renewal Movement (Srpski pokret obnove, SPO) and the Civic Alliance of Serbia (Građanski savez Srbije, GSS). All three parties were opposed to Slobodan Milošević's administration. Zajedno won a significant victory in the Belgrade city elections, and Đurišić was one of the DS candidates elected under its banner.^[2] Milošević's government initially refused to recognize the opposition's victory but accepted the outcome in early 1997 following extended street protests. The city assembly convened in February 1997, and DS leader Zoran Đinđić became Belgrade's mayor. The coalition's triumph was short-lived; the SPO left Zajedno later in the year, Đinđić was removed as mayor, and the DS moved into opposition. Đurišić later took part in public protests against Milošević's government in July 1999, following the NATO bombing of Yugoslavia.^[3]

In 2000, the DS became one of the leading parties in the Democratic Opposition of Serbia (Demokratska opozicija Srbije, DOS), a broad and ideologically diverse coalition of parties opposed to the Milošević regime. DOS candidate Vojislav Koštunica defeated Milošević in the 2000 Yugoslavian presidential election, a watershed moment in Serbian and Yugoslavian politics. The DOS also won a landslide victory in the Belgrade city assembly in the concurrent 2000 Serbian local elections. Đurišić was re-elected to the assembly for New Belgrade's third division and served as a government supporter for the next four years.^[4] He was also elected to the New Belgrade municipal assembly, where the DOS won sixty-five out of sixty-seven seats.^[5]

Serbia adopted a system of proportional representation for local elections in 2002. Đurišić appeared on the DS's electoral lists for the Belgrade city assembly and the New Belgrade municipal assembly in the 2004 local elections but was not given a mandate for a new term in either body.^[6][7]

Parliamentarian (2001–12)

The Serbian government fell after Milošević's defeat in the 2000 Yugoslavian election, and a new Serbian parliamentary election was called for December 2000. Đurišić received the ninety-fourth position on the DOS's list and was awarded a mandate when the alliance won a landslide victory with 176 seats out of 250.^[8][9] (From 2000 to 2011, assembly mandates were awarded to sponsoring parties or coalitions rather than to individual candidates, and it was common practice for the mandates to be assigned out of numerical order. Đurišić was not automatically elected by virtue of his list position, though he received a mandate all the same.)^[10] He took his seat when the assembly convened in January 2001; shortly thereafter, he accompanied DS deputy chair Boris Tadić on an official visit to Germany.^[11] During his first term, he served on the committee for international relations, the committee for transport and communications, and the finance committee.^[12]

The DS contested the 2003 Serbian election at the head of its own alliance and won thirty-seven mandates. Đurišić received the 147th position on the party's list.^[13] He was not included in the DS's initial delegation but received a mandate on 17 February 2004 as the replacement for another party member who had resigned.^[14][15] The DS served in opposition in this sitting of parliament. In August 2005, Đurišić attended an event in Poland commemorating the twenty-fifth anniversary of the founding of Solidarity.^[16]

Đurišić received the sixty-seventh position on the Democratic Party's list in the 2007 parliamentary election.^[17] The list won sixty-four seats; he was again not immediately included in his party's delegation but received a mandate on 22 May 2007 as the replacement for another member.^[18] The DS formed an unstable alliance with the rival Democratic Party of Serbia (Demokratska stranka Srbije, DSS) and G17 Plus after the election, and Đurišić again served as a government supporter. In his third term, he was the deputy leader of the DS's assembly group, a member of the defence and security committee, and the leader of Serbia's delegation to the NATO Parliamentary Assembly (where Serbia has observer status).^[19][20]

Đurišić was the chief of DS incumbent Boris Tadić's campaign staff in the 2008 Serbian presidential election, which was held over two rounds in January and February. Tadić won re-election and afterward commended Đurišić for his work on the campaign. Soon after the vote, Đurišić was described as having "bawled out" a journalist who asked a challenging question about the DS's coalition partners, and the newspaper Politika ran an editorial criticizing his actions.^[21] Tadić accused Politika of having illegally recorded a conversation with Đurišić; Politika rejected the charge and defended its actions on the basis of a commitment to the freedom of the press.^[22] These events led to some friction between the newspaper and the administration.

The DS–DSS alliance broke down in early 2008, and a new parliamentary election was held in May of that year. The DS contested the election at the head of the For a European Serbia (Za evropsku Srbiju, ZES) alliance. Đurišić received the fifty-ninth position on the alliance's list, which won a plurality victory with 102 out of 250 seats, and was afterward given a mandate for a fourth term.^[23][24] The overall result of the election was inconclusive, but ZES ultimately formed a new coalition government with the Socialist Party of Serbia (Socijalistička partija Srbije, SPS), and Đurišić again served as a government supporter. Following the consolidation of the ZES–SPS alliance at the republic level, Đurišić announced that the alliance would also cooperate in municipal governments across the province of Vojvodina.^[25] In August 2009, he expressed the view that Serbian politics was likely shifting in the direction of a two-party system, with the Democratic Party and the Serbian Progressive Party (Srpska napredna stranka, SNS) at the head of rival blocs.^[26] He continued to serve on the defence and security committee and to lead Serbia's delegation to the NATO parliamentary assembly, as well as being a deputy member of the foreign affairs committee and the committee for European integration.^[27]

Serbia's electoral system was reformed in 2011, such that parliamentary mandates were awarded in numerical order to candidates on successful lists. Đurišić received the eighty-fifth position on the Democratic Party's Choice for a Better Life coalition list in the 2012 Serbian parliamentary election and was not re-elected when the list won sixty-seven seats.^[28] He also appeared in the twenty-fourth position on the party's list for the New Belgrade municipal assembly in the concurrent 2012 Serbian local elections and was re-elected to that body when the DS won thirty-one mandates and formed a new government under the local leadership of Aleksandar Šapić.^[29][30]

The SNS and SPS formed a new coalition government at the republic level after the 2012 election, and the DS moved into opposition. After its fall from power, the DS increasingly became divided into rival wings led by Boris Tadic and Dragan Đilas. Đurišić sided with Tadić. In December 2012, he voted against an internal party decision for former ministers to return their parliamentary mandates (i.e., resign from the legislature).^[31]
