He has served several terms in the National Assembly of Serbia as a member of the far-right Serbian Radical Party and was justice minister for the Federal Republic of Yugoslavia from 1999 to 2000.
[10] In April 2000, he urged the United Nations Security Council to release former Bosnian Serb leader Momčilo Krajišnik from custody in The Hague, saying that he had been arrested "in a terrorist fashion.
"[11] On May 24, 2000, Jojić released a twenty-five-page open letter to the international tribunal that, among other things, described the court as "not an international legal institution but a criminal organization that consists of mercenaries, spies, scumbags, America's and NATO's servants," and accused chief prosecutor Carla del Ponte of "running the dungeon which, like the worst whore, you have sold out to the Americans and to which you bring innocent Serbs by force, by kidnapping and murder.
[13] Days after his appointment as justice minister, Jojić warned leaders of a planned opposition rally in Belgrade that the state would respond with "all available means" if protesters committed any acts of violence.
While he advised opposition leaders (some of whom he described as "Western stooges") that they had a legal right to hold the rally, he added that state institutions would be obligated to take "timely and effective" measures if "the smallest incident, or an attempt to instigate violence" occurred.
He wrote, "the applicants have been acting illegally for some time and in violation of our regulations, for instance by organizing public meetings and inciting citizens to revolt in order to bring down the constitutional system.
"[15] In September 1999, Jojić said that Yugoslavia's new penal code (which, among other things, abolished capital punishment and replaced it with life sentences), would be valid in the whole of the country – including in Montenegro, where some had questioned its implementation.
[16] He later said that the government of Montenegro's amnesty to 14,000 Montenegrin citizens who refused to join the Yugoslav army during the NATO bombing would undermine Yugoslavia's legal system.
[17] Jojić helped steward the passage of an electoral reform law in July 2000 that, along with other changes, permitted Yugoslav president Slobodan Milošević to seek re-election.
Before leaving office, Jojić refused an order from Koštunica to begin clemency hearings for Flora Brovina, a Kosovar Albanian who had been convicted of aiding separatists in Kosovo and Metohija and was widely regarded as a political prisoner.
[31] Jojić was elected to the Pančevo municipal assembly in 2008 at the head of the local Radical Party list and served in opposition to the city's coalition government for the next four years.
[38] Foreign affairs minister Ivica Dačić responded in August 2016 that Serbia's law on extraditions had been adopted by the Serbian parliament in cooperation with international agencies, that no objections were raised at the time, and that the tribunal had no authority to propose changes.
