Kazushige Yamashita, director of the division in charge of screenings, said the ruling is reasonable because it confirmed the legitimacy and need for the screenings.

The Yokohama District Court partially accepted Takashima's claim in April 1998 and ordered the state to pay 200,000 yen in compensation to him, but the Tokyo High Court overturned the lower court ruling in May 2002.

The district court found that two of the four changes the then Education Ministry told Takashima to make were illegal.
