During the 1990s, most members of the Kosovo Albanian community boycotted Serbian state institutions and participated in parallel governing structures. Jonuzi was elected to the "parallel" parliament as a LDK member in the 1992 general election.[2] In February 1998, he was elected to the LDK's general council.[3] He assisted internally displaced Albanians from the Vushtrri area in the early period of the Kosovo War (1998–99).[4]
Jonuzi appeared in the second position on the LDK's electoral list for Vushtrri in the 2000 Kosovan local elections and was elected when the list won twenty mandates.[5][6] He served for one term and did not seek re-election in 2002.
Jonuzi appeared in the twenty-eighth position on the LDK's list in the 2001 Kosovan parliamentary election, which was held under closed list proportional representation, and was elected when the party won a plurality victory with forty-seven seats.[7][8] The LDK formed a coalition government after the election; Jonuzi served as a supporter of the administration and was a member of the assembly's trade and industry committee.[9]
He was promoted to the twenty-sixth position on the LDK's list in the 2004 parliamentary election and was re-elected when the list again won forty-seven mandates.[10] The LDK formed a new coalition government after the election, and Jonuzi continued to serve as a government supporter. In his second term, he chaired the assembly committee on economy, trade, industry, energy, transport, and telecommunications.[11]
All parliamentary elections in Kosovo since 2007 have been held under open list proportional representation. In the 2007 parliamentary election, Jonuzi finished in fifty-sixth place among the LDK's candidates.[12] The list won twenty-five seats, and he was not re-elected.
Jonuzi ran for mayor of Vushtrri in the 2009 local elections and finished third. He has not returned to active political life since this time.
