The Chiba District Court has denied an insurance payment to a woman over the 1998 death of a man she was living with, ruling she is not eligible to receive the money because the man was apparently poisoned -- possibly by her.

The Chiba District Court's Sakura branch handed down the ruling Wednesday in the civil suit filed by a 38-year-old Filipino woman registered as the beneficiary in the man's life insurance policy, court sources said Thursday. Their names have not been released.

The man, a construction worker, died in August 1998 at age 34.

"It can be assumed that the man died because of acute poisoning for insurance money," Judge Junichi Takeuchi said in the ruling.
