Andras Baka, a strong advocate for judicial independence, becomes Tisza’s pick for Hungary’s next president.

Hungary’s governing Tisza party has nominated Andras Baka, a former Supreme Court chief removed from his post by Viktor Orban’s government in 2012, as its candidate for the country’s presidency.

The nomination, announced Saturday by Prime Minister Peter Magyar, marks the latest step in Tisza’s effort to dismantle Orban’s influence over state institutions since the party’s landslide election victory in April ended his 16-year rule.

The decision to nominate Baka for the presidency comes weeks after Tisza used a constitutional amendment to remove Orban-era President Tamas Sulyok from office.

On Tuesday, Baka, 73, is expected to be elected by parliament, where Tisza holds a constitutional majority.

Magyar wrote on Facebook that the nomination, made by secret ballot within the party’s parliamentary group, was “one of its most important decisions so far”.

Tisza lawmakers said Baka had always “attached paramount importance to the principle of separation of powers, consistently standing up for the rule of law and judicial independence”, adding that his experience represented “a significant asset” as the party lays “the foundations for Hungary’s new constitutional order”.

Fidesz, the party now in opposition, said it would boycott the vote, accusing Tisza of authoritarian tactics – allegations it denies.

Baka served two terms as a judge on the European Court of Human Rights in Strasbourg before being elected head of Hungary’s Supreme Court in 2009.

He was removed two years later after publicly criticising Orban’s government reforms, which he said threatened judicial independence. The European court later ruled that his dismissal had violated his rights to a fair trial and freedom of expression, a judgement the Council of Europe said Hungary failed to fully implement.

Hungary’s presidency carries mostly ceremonial powers, with limited authority to veto or refer legislation, though the nomination is being treated as a heavily symbolic move.
