These results proved to be extremely contentious, and the legitimacy of the Bosniak Cultural Community's victory was contested by both the Serbian government and Ugljanin's party.
[4][5] Elfić resigned as assistant to Novi Pazar's mayor in September 2010, citing what he described as government discrimination against the Bosniak community and attempts by the state to utilize waqf property for secular purposes.
[6] In September 2010, Elfić was chosen as leader of the newly formed Bosniak Democratic Union (Bošnjačka demokratska zajednica, BDZ), a political party closely associated with Zukorlić's movement.
"[9] In January 2012, Elfić condemned Serbian president Boris Tadić for attending a twentieth-anniversary celebration of the Republika Srpska in Banja Luka (commemorating the anniversary of the entity's de facto creation prior to the Bosnian War, not its sanctioned establishment in the Dayton Agreement).
Elfić argued that the event commemorated the foundation of a "parastate and paramilitary" that committed aggression against Bosnia and Herzegovina and ethnic cleansing against the Bosniak community.
[10] The BDZ contested the 2012 Serbian parliamentary election as part of the All Together alliance, which also included parties representing Serbia's Croat, Slovak, and Hungarian communities.
After leaving parliament, Elfić became aligned with Rasim Ljajić's Sandžak Democratic Party (Sandžačka demokratska partija, SDP).
