In the 2014 elections, Vetëvendosje received 13,59% (99.397 votes), remaining the third strongest political force in the Kosovo Assembly with 16 seats. Despite PDK's electoral victory, Vetëvendosje, along with the LDK-AAK-Nisma coalition, tried to thwart PDK by attempting to form a new government together. A decision by the Constitutional Court of Kosovo that deemed Isa Mustafa's election as Chairman of the Assembly of Kosovo unconstitutional, led to the breakup of the LDK-AAK-Nisma coalition and LDK joining a coalition with PDK, in which Isa Mustafa assumed the position of prime minister. This led to Vetëvendosje taking the role of leader of the opposition, with AAK and NISMA being part of it. The Vetëvendosje-led opposition was very aggressive, opposing the border demarcation between Kosovo and Montenegro and the formation of the Association of Serb Municipalities. LDK was accused of betraying the opposition and keeping PDK in power. The opposition organized massive demonstrations on the streets, and it used tear-gas to block meetings of the parliament.
