Key legal question
Whether a long-term cohabiting partner must be exempted from inheritance tax like spouses or registered partners.
Extracted holding
No. The statutory exemption for spouses and registered partners does not extend to concubine partners.
Extracted reasoning
The wording of the cantonal tax act is clear, the legislative history shows a deliberate decision not to privilege concubinage, and no later societal change justifies departing from that clear text.
