No, you got it quite right I think. The government agency in question has a deal with Postnord (owned mainly by the Swedish state) to utilise them for all mail services. License plates has to be sent by mail. Postnord employees refuses to do so to Tesla. I believe they've also said they'd refuse to hand them out to Tesla should they come asking for them. In effect, not legal way for Tesla to sell cars in Sweden at this point.
