Key legal question
Whether the waiver of a purchase right in favor of a third party triggers transfer tax under § 206 Abs. 1 lit. b StG.
Extracted holding
Yes. A waiver of the exercise of a purchase right in favor of a third party is a taxable transfer when it causes a change in economic control over the property.
Extracted reasoning
The court held that the tax applies to economic transfers of real estate. For a purchase right, tax is due once the holder not only acquires the right but also disposes of it by exercising it or waiving it in favor of a third party. Here, X. enabled Z-AG to acquire the parcel, so the statutory taxable event occurred.
