Key legal question
Whether the cantonal and municipal tax burden amounted to confiscatory taxation in violation of property protection.
Extracted holding
No confiscatory taxation was established; the strict conditions developed by the Federal Supreme Court were not met.
Extracted reasoning
Although the burden was high, the taxpayers' income was not entirely taxed away, their assets increased substantially over several years, and there was no deprivation of substance or prevention of wealth creation. The court also noted that the duration, cumulation of taxes, and lack of transferability did not suffice to show confiscatory taxation in this case.
