The draft amendment would allow to implement the European Court of Human Rights' ruling in the Paksas case.
Under the amendments proposed by Žemaitaitis, a person removed from office through impeachment, or a person who lost his/her parliamentary mandate, may no run for parliament for four years.
If the Constitutional Court rules that a person has breached an oath, he/she will not be able to run for parliament for eight years after the ruling comes into force, according to the proposal.
Žemaitaitis also suggests including a provision into the Constitution that a person, who has been recognized by the Constitutional Court as having breached an oath, cannot assume an office involving a constitutional oath for eight years following the ruling.
The Seimas of Lithuania is currently hearing a proposal to ban individuals removed from office through impeachment to run for parliament for ten years.
Last December, the Seimas gave its initial backing to a draft constitutional amendment banning such people to run for parliament for four years.
The Constitutional Court of Lithuania has ruled that a person removed from the office of president, Constitutional Court president or judge, Supreme Court president or judge, the Court of Appeals' president of judge, or a person who lost his/her parliamentary mandate can never assume any office involving a constitutional oath.
The ECHR later ruled that such a lifelong ban is not proportionate and ordered to change legal regulation.
In Lithuania, at least 94 members of the Seimas need to vote two times for proposed constitutional amendments.
Paksas was removed from his presidential office through impeachment in April 2004 over a breach of the oath and gross violation of the Constitution after granting Lithuanian citizenship to his key campaign sponsor Yuri Borisov.
