I saw a similar comment in the last week or so (might have been on TikTok?) but it was specifically Japanese court that they'd said they'd never lost in. I don't know if it's accurate though, took it at face value and didn't really think much about it.
Japanese courts have a 99% conviction rate or something. Saying you've not lost in a Japanese court is like saying 99% of the time you've been to the airport, you got on a plane.
