Key legal question
Whether Art. 21 SBBG bars cantonal and municipal real estate gains tax on SBB property not necessary for railway operations.
Extracted holding
No. The exemption under Art. 21 SBBG applies only to activities linked to public transport; property without a necessary operational connection may be taxed, including real estate gains tax.
Extracted reasoning
The Court held that the special wording and legislative history of the new SBBG showed a restriction of the former broad exemption. The SBB's transformation into a special statutory company justified narrower tax immunity and alignment with competitive neutrality.
