When the school's principal told them not to return until they cut their hair, they went to the offices of Politika to plead their case in the national media.
Although the principal later threatened them with expulsion, they received letters of support from throughout Yugoslavia and were reportedly protected by Ivica Račan, at the time a leading figure in the League of Communists.
Serbia afterward introduced a system of proportional representation for parliamentary elections, and in the December 1992 vote Kojčić led the electoral list of Blažo Perović's Democratic Fatherland Coalition in the Belgrade constituency.
Kojčić signed a petition in late 1997 calling for the International Criminal Tribunal for the former Yugoslavia (ICTY) to suspend its proceedings against former Bosnian SDS leader Radovan Karadžić.
[8] In the same period, he travelled to Pale in the Republika Srpska to protest against the closure of the nationalist Serb Radio and Television outlet by the North Atlantic Treaty Organization (NATO).
[11] Kojčić's early years as leader of the Serb Democratic Party of Serbia coincided with a period when the Serbian National Renewal (SNO) movement was a constituent part of the organization.
Jović has said that the main board of the SDSS voted to join the Alliance for Change but that Kojčić refused to implement the decision, leading to a party split and the departure of the SNO.
Kojčić was appointed as deputy minister of relations with Serbs outside Serbia], a role he held until a new government was formed in January 2001.
[15] In November 2003, the Democratic Party of Serbia announced that Kojčić would appear on its electoral list as a representative of the SDSS in the 2003 Serbian parliamentary election.
Kojčić angrily denied reports that he had negotiated with Bogoljub Karić to join the Strength of Serbia Movement (PSS) in 2005, but he made no secret of his dissatisfaction with the DSS, saying, "It would be useful for the party for me to be vice president, but I am a nuisance to those who are afraid of my professional authority and competence."
He released a book of political philosophy entitled The Arrow of Time and the Horizon of Freedom (Strela vremena i horizont slobode), outlining a vision of national conservatism that also favoured Serbia's entry into the European Union (EU).
[28][29][30] Kojčić briefly joined the newly formed Rich Serbia (BS) party at the conclusion of these efforts, although this arrangement did not last very long.
