Marjanović was first elected as mayor of Boljevac in the
2004 Serbian local elections as a candidate of the
Democratic Party of Serbia (Demokratska stranka Srbije, DSS). He continued as mayor under the same party's banner following the
2008 Serbian local elections. Marjanović also was included on the DSS's coalition
electoral list with
New Serbia in the
2008 Serbian parliamentary election, in the 141st position.[2] The list won thirty mandates, and he was not included in his party's assembly delegation. (From 2000 to 2011, parliamentary mandates were awarded to sponsoring parties or coalitions rather than to individual candidates, and the mandates were often assigned out of numerical order. Marjanović could have received a parliamentary mandate despite his list position, but in the event he did not.)[3]
He subsequently left the DSS and joined the
United Regions of Serbia (URS), which he led to victory in Boljevac in the
2012 Serbian local elections.[4][5] He also appeared in the thirty-fourth position on the URS's electoral list in the
2012 parliamentary election.[6] Following a 2011 electoral reform, assembly mandates were awarded in numerical order to candidates on successful lists; the list won sixteen mandates, and he was not returned.
^Serbia's Law on the Election of Representatives (2000) stipulated that parliamentary mandates would be awarded to electoral lists (Article 80) that crossed the
electoral threshold (Article 81), that mandates would be given to candidates appearing on the relevant lists (Article 83), and that the submitters of the lists were responsible for selecting their parliamentary delegations within ten days of the final results being published (Article 84).
