The Regional Tax Court of Muenster held that a loss from the exchange of profit participation rights for shares in a registered cooperative ("eG") and bonds may be set off against income from capital investments. Thus, the tax office's attempt to regard the loss as belonging to the non-taxable private asset portfolio of the plaintiff failed.
The ECJ has held that if a country excludes capital gains and losses on investments from taxation, the exclusion may also extend to that part of the loss that directly resulted from exchange rate fluctuations.
