A Greek court ruled on Wednesday that the far-right Golden Dawn party was operating as a criminal organization, delivering landmark guilty verdicts following a politically charged five-year trial against dozens of defendants.  The court ruled that seven of the 18 former lawmakers, including Nikos Michaloliakos, the head of the party which had become Greece’s third largest during the country’s financial crisis, were guilty of leading a criminal organization. The others were found guilty of participating in a criminal organization.

As news of the guilty verdicts broke, cheers and celebrations erupted among the crowd of at least 20,000 people gathered in an anti-fascist rally outside the Athens courthouse. A small group threw Molotovs and stones, with police responding with tear gas and water cannon. The marathon trial had been assessing four cases rolled into one: the 2013 fatal stabbing of Greek rap singer Pavlos Fyssas, physical attacks on Egyptian fishermen in 2012 and on left-wing activists in 2013, and whether Golden Dawn was operating as a criminal organization.

The 68 defendants included the 18 former lawmakers from the party that was founded in the 1980s as a neo-Nazi organization and rose in prominence during the country’s decade-long financial crisis. Prime Minister Kyriakos Mitsotakis said the verdict “ends a traumatic cycle” in the country’s public life.  “Its political dimension has, fortunately, been judged by the victory of democracy, which expelled the Nazi formation from Parliament (in elections),” he said. “Now, the independent judiciary is giving its own answer.”

The three-member panel of judges also found Giorgos Roupakias guilty of the murder of Fyssas, prompting applause inside the courtroom and among the crowd outside. Roupakias had been accused of being a party supporter who delivered the fatal stab wounds to Fyssas. Another 15 defendants ? none of them former lawmakers ? were convicted as accomplices. Leaving the courthouse, Fyssas’ mother Magda Fyssa, who had attended nearly every court session over the last five years, raised her arms and shouted: “Pavlos did it. My son!”
