'Just for fun' bonitation in Osieczna (PL)

[Rona]

Could somebody help me understand how the bonitation cards circulation operate?

Are the empty cards (and later, the bonitation documents) strictly registered and numbered by the national CSV clubs? Or, if the bonitation is organized in another country, can they be issued by the local national CSV clubs in their language and registered there?
What if there is no country CSV club? Where do the original bonitation cards of the bonitated dogs go in that case?

Is it enough, if the bonitation cards are signed only by the judge or do they need to be signed by the whole commission? Is it possible to issue copies in other languages or only in the original language?

I'm just curious because we are having a lively discussion on the Polish forum re the bonitatin formalities and opinion of people who organize bonitations in various countries would be appreciated.
