Key legal question
Whether the appellant, as both legatee and sole heir, is subject to Solothurn estate tax on the bequeathed property.
Extracted holding
Yes. As sole heir for the whole estate, she is liable for the Solothurn estate tax; the fact that the apartment was also a legacy does not exclude liability.
Extracted reasoning
The estate tax applies to the net estate, and liability attaches to heirs. A legacy only creates a claim to transfer a specific asset; it does not remove that asset from the inheritance relationship of the sole heir.
