On 18 September 2009, the Supreme Court ruled that undeclared savers in danger of being caught must also answer the tax authorities' questions. A black saver argued that the tax authorities were not allowed to force him to answer through the civil courts. Moreover, the black saver was of the opinion that he did not have to cooperate with his own conviction. The Supreme Court rejected the taxpayer's position and ordered the taxpayer to pay the tax authorities' legal fees and litigation costs, something that does not happen very often. Black savers would be wise to choose eggs in time for their money.
