Cvijan was later an independent representative in the parliament and an active dissident for a short period until his unnoticed disappearance in 2014.

Before that, there was no single trace of his fate, except for some tabloid claims that he allegedly fled the country to the United States in 2017.

[7] He was the target of public criticism as the legal representative of Sreten Jocić, better known as Joca Amsterdam, in the trial for the murder of the Croatian journalist Ivo Pukanić.

[6] He left the staff of the Presidency in March 2010, according to him, due to disagreements over the re-election of judges, and joined the emerging Serbian Progressive Party (SNS) the following month.

In February 2021, Srđan Milivojević of the opposition Democratic Party, gave an interview stating that Cvijan could be one of the victims of Veljko Belivuk's criminal organization, which was accused of abductions and murders of several people in Serbia and Montenegro.

[24][better source needed] On the same day, the Bar Association of Serbia announced that Cvijan had been removed from the register of active lawyers, "due to his death".

President of the Bar, Viktor Gostiljac told the media that this was done after learning that Cvijan had died, but he could not specify when that had occurred.

[26] The same day, the Higher Public Prosecutors Office revealed that Cvijan had drowned in the Danube river in Belgrade on 5 January 2018.

[33] On 23 March 2021, it was revealed that Cvijan was cremated and buried on 19 January 2018 at the Lešće cemetery, and the urn with his remains is only identified by his first name.

[36] Opposition activist, former head of the Military Security Agency, founding member and MP of the ruling SNS, Momir Stojanović, stated on 17 March 2021, that Cvijan knew a lot about the activities of the SNS-led government and that he most likely "suffered" because of that knowledge.
