The lawyer has been authorized to do so by the Presidium of the Labor Party, the party's information center has said on Thursday.
The presidium believes the prosecutor, who has filed a motion to stop the merger of the Labor Party with another party, the Order and Justice, is not only politicizing but also is in breach of the Constitution.
"I don't know what motives they are going to present. If they find arguments I won't have the opportunity to reject, then I should remove myself. But I have doubts such arguments can be presented," Verseckas told BNS.
On Wednesday, the prosecutor asked the court to stop the party merger as in that case the Labor Party would cease to exist and would avoid prosecution.
In November, Viktor Uspaskich, leader of the Labor Party, tried unsuccessfully to have Verseckas removed. The court then rejected the request saying that Uspaskich failed to provide objective data to base his request.
The Councils of the Labor Party and the Order and Justice party on Sunday approved the merger. The merger convention might be held as early as April.
Vilnius Regional Court, currently hearing the Labor Party's case, has been adjourned until March 12 after Uspaskich suffered a suspected heart attack earlier this week.
The court, however, will hold a hearing on Friday to hear the prosecutor's request to restrict the Labor Party's activities.
The Labor Party is charged with failing to include more than 24 million litas (EUR 6.9m) in income and 23 million litas in spending into its books between 2004 and 2006.
Uspaskich, the Labor Party's leader, Deputy Speaker of the Seimas Vytautas Gapšys, and MP Vitalija Vonžutaitė are currently standing trial for organizing fraudulent bookkeeping while holding top positions at the Labor Party's Vilnius bureau in 2004-2006. In addition to the three parliamentarians, charges in the case have been brought against the party as a legal entity and its former financial officer Marina Liutkevičienė.
The Labor Party's members strongly deny the accusations, saying the case is politically-motivated.
Gapšys and Liutkevičienė were expected to testify on Tuesday. Uspaskich had said he would give testimony on Tuesday as well, although he refused to do so on Monday, voicing his no-confidence in the court. Meanwhile Vonžutaitė has refused to testify at all.
The hearing cannot continue without all defendants present.
The case reached court on April 14, 2008.
