Key legal question
Whether the direct postal service of the bankruptcy warning to Germany was permissible.
Extracted holding
No. The direct postal service violated applicable treaty rules and was therefore null.
Extracted reasoning
For service of enforcement documents abroad, foreign authorities must generally be used; direct postal service is allowed only if a treaty permits it or the receiving state consents. Germany and Switzerland had both objected under the Hague Service Convention, and the relevant bilateral arrangements required judicial assistance rather than direct postal delivery.
