Kernrechtsfrage
Whether the cantonal judgment could be served directly by post to the representative in Germany.
Extrahierter Entscheid
Yes. Direct postal service was permissible under Art. 32 of the 1964 Switzerland-Germany social security agreement; the FZA and its coordination regulations did not exclude that method.
Extrahierte Begründung
The FZA suspended bilateral social security treaties only where it regulated the same subject matter. The coordination regulations do not positively or negatively regulate direct judicial postal service, so the bilateral rule remained applicable.
