Kernrechtsfrage
Whether the gain from the transfer of the land share was private capital gain or taxable income from self-employment/business assets.
Extrahierter Entscheid
The gain was taxable income from self-employment because the heirs' coordinated, planned development activity amounted to a taxable real-estate dealing business.
Extrahierte Begründung
The heirs formed a simple partnership to clarify building possibilities, cooperated with the municipality and professionals to create a development plan, and actively increased the property's value; such systematic and planned conduct exceeds mere asset management.
