On 16 October 2012, the CJEU delivered its Grand Chamber judgment in the infringement procedure (Case C-364/10 Hungary v Slovakia) which was initiated by Hungary against Slovakia for refusing the Hungarian President entry into Slovakian territory. It is already quite rare that Member States initiate infringement procedures against each other. Normally the Commission takes up this task, as guardian of the Treaties, but it refused to do so in this case.
Mr Sólyom, the President of Hungary, was invited to a ceremony for the inauguration of a statue of Saint Stephen of Hungary (a Medieval Hungarian King) in the Slovakian town of Komárno. The ceremony was planned for 21 August 2009. 21 August is a sensitive date in Slovakia, since Warsaw Pact troops, among which were Hungarians, invaded Czechoslovakia on 21 August 1968. Therefore, Slovakian authorities found the planned visit inappropriate.
