The Austrian Supreme Court has confirmed the sentences in the high-profile Buwog corruption case, involving former Finance Minister Karl-Heinz Grasser and ex-FPÖ official Walter Meischberger.

Grasser, initially sentenced to eight years, will now serve four years due to the "exorbitant duration" of the legal process.

Meischberger's sentence was reduced to 3.5 years.

Both were convicted of corruption, including embezzlement and bribery, linked to the Buwog housing sale.

Despite the reductions, both men claim the rulings are unjust and plan to appeal to the European Court of Human Rights.

The case, which began in 2009, has become a symbol of Austria's fight against political corruption.
