Čabradi led the Green Party's electoral list in the 2016 Serbian parliamentary election, in which the party ran in an alliance with Jan Paul's Slovak Party and other smaller groups. The party received 23,890 votes, well below the five per centelectoral threshold normally required for representation in the assembly. As the list was recognized as representing the country's Slovak minority, however, the threshold requirement was waived, the party was awarded one seat, and Čabradi was duly declared elected. In September 2016, a group of dissident Green Party members sought to remove Čabradi as party president. The rebels, led by Slavica Vasilijević, charged that Čabradi was governing the party in an arbitrary fashion and particularly opposed his decision to support a resolution on the Srebrenica massacre that, in their view, described the Serbian people as genocidal. The Slovak Party, which also opposed the Srebrenica resolution, urged Čabradi to resign his mandate. Online sources do not indicate exactly how this situation was resolved, though it seems to have resulted in a party split. By March 2017, the Green Party's website continued to list Čabradi as president, while the website for a rival group called the "Green Party of Serbia" listed Vasilijević as president. Following his election to the assembly, Čabradi originally served in a parliamentary group with Nenad Čanak's League of Social Democrats of Vojvodina. He left the group in February 2017, ironically after Čedomir Jovanović of the Liberal Democratic Party had agreed to join it to ensure it would not lose its official status in the assembly. Since then, Čabradi has not been aligned with any parliamentary group. In June 2017, Čabradi introduced a bill to legalize medicinal marijuana in Serbia. Although he is not formally aligned with Serbia's coalition government, he voted in favour of Serbian president Aleksandar Vučić's nomination of Ana Brnabić for prime minister later in the same month after the government agreed to establish a ministry of environmental protection. Early in his mandate, Čabradi was a member of the parliamentary environmental protection committee and the committee on the rights of the child, and a deputy member of the agriculture, forestry, and water management committee. He is a member of the parliamentary friendship groups for Austria, Germany, Spain, and Sweden.
