UDRP: cultural imperialism

[Marc Schneiders]

Am I very biased as a non-native speaker of English? The UDRP case
below was conducted in English even if the rules said it should/could
be in Korean and the respondent demanded that. Reason: Respondent had
replied in English, so has enough English. So never do that?

It is a most curious case in other respects as well. Complainants do
not seem to have to prove anything anymore. Mere assertions suffice.
Well.
