The head of state said Constitutional Court rulings must be executed, and she refused to express her personal opinion.
"I have a varied personal opinion but, as president, I can only say this: I don’t comment on Constitutional Court rulings, they must be executed. I will keep my personal opinions to myself," the president told journalist.
Lithuania's Constitutional Court ruled on Wednesday that a law allowing Paksas to run for parliament contradicts the Constitution.
The Court said that based on a previous ruling by the European Court of Human Rights, not only a national law but also the country's Constitution should be amended.
The court ruled on the amendment adopted by the parliament last spring, which stipulated that people removed from office by impeachment cannot run for parliament for four years after impeachment. The earlier version envisaged a lifetime ban.
The ban was based on an earlier ruling of the Constitutional Court. In 2004, it said a person who has breached constitutional oath can never again hold a position that requires giving oath.
The Constitutional Court said that the 2004 legal position carried the meaning of a precedent and was binding.
Paksas was impeached and removed from office in April 2004 for breaching his oath and a gross violation of the Constitution after he granted Lithuanian citizenship by his decree to his key financial supporter Yuriy Borisov.
The Seimas elections are scheduled on 14 October.
