Interesting part of the judgement:
"The judge determined the pre-race agreement between Ota and the organizers not to pursue legal action in the event of an accident was unacceptable.<sup id="cite_ref-Mainichi_2-7" class="reference"></sup> Despite his written pledge to organizers not to seek compensation in the event of an accident, which all drivers were required to sign, the judge ruled it unfair and said it runs counter to public order and morals.
