In what many see as a landmark victory, the ECtHR rejected Switzerland's appeal to convict Turkish politician Dogu Perincek, over the denial of the Armenian genocide.
The ECtHR concuded that denying the genocide was not at attack on the dignity of individuals in the Armenian community.
Perincek, who is the chairman of the Turkish Workers' Party made the above mentioned statement in 2005 in Switzerland. Shortly after, a lobby group calling themselves Switzerland -Armenia filed a criminal complaint against Perincek in July using the legal pretext- it is illegal to deny the genocide in Swiss anti-racism law.
In 2007, a court in Switzerland found Perincek guilty of racial discrimination and fined in the amount of 3000Swiss franks.
In June 2008, Perincek lodged an official application to the ECtHR saying his freedom of expression was breached.
In December 2013, the ECtHR said his convinction in Switzerland was "unjustified" and ruled in favor of Perincek. The verdict was appealed by Switzerland.
This time Armenia requested to join the lawsuit as co-plaintiff and was represented by human rights lawyer Amal Clooney.
In his tweet shortly after the hearing Perincek said, "This is a history discussion, not a legal dispute. This is defense of ones motherland! This is war of independence!"
