Democratic Party of Japan kingpin Ichiro Ozawa sued the government Friday, claiming a judicial panel's move to indict him for falsifying political funds reports is illegal and invalid.

Ozawa's lawyer also filed for an injunction to stop the Tokyo District Court from selecting attorneys who will act as prosecutors in the trial. The court has asked the Daini Tokyo Bar Association to recommend three lawyers for the post by Oct. 22.

It is unclear how Ozawa's lawsuit will affect this move.
