Some Slovaks who had been granted Hungarian citizenship during the last two years were prevented from voting in today’s Slovak parliamentary elections because, according to the terms of a 2010 amendment to the Citizenship Act, any Slovak who accepts the citizenship of another state automatically loses their Slovak citizenship, the TASR newswire reported.

Three inhabitants of Levice district, as well as Komárno businessman Olivér Boldoghy, who publicly announced before the election that he had been granted Hungarian citizenship, were not allowed to vote by local election committees after they showed their identity cards.

Boldoghy responded that the election commission was violating his constitutional rights and said that the Constitutional Court had already begun dealing with a complaint challenging the constitutionality of the 2010 amendment, TASR wrote.

“I think that it is very sad what happened today,” said Boldoghy, as quoted by TASR. “It is 21st-century, Europe, and they did not allow a person to vote, as if we were at some time in the 1950s.”

Boldoghy added that he was considering filing a complaint with the district court.
