Key legal question
Whether the confiscated postage stamps had to be destroyed or could be devalued and returned to the owner.
Extracted holding
The stamps may be confiscated, but destruction is disproportionate if devaluation can reliably prevent reuse; after devaluation they must be returned.
Extracted reasoning
Postage stamps are official value marks and may be confiscated under Art. 249 StGB. However, proportionality requires the least intrusive effective measure. Since devaluation removes any risk of confusion and the items can still have collector value, destruction was unnecessary.
