The head of a political group that filed a criminal complaint against former Foreign Minister Makiko Tanaka requested Wednesday that the prosecutors' decision to drop the case be reviewed. The request was filed with the Tokyo Committee for the Inquest of Prosecution.

In the original complaint, filed in April 2002, the Nara-based political organization alleged that Tanaka misappropriated some 6 million yen from the government, because the salary of a secretary was in fact being paid by Echigo Kotsu Co., a bus firm in Nagaoka, Niigata Prefecture, with close ties to the Tanaka family.

The secretary was on loan from Echigo Kotsu.

The Tokyo District Public Prosecutor's Office decided late last month not to press charges against Tanaka, saying the secretary was actually working for her.
