The cabinet had appealed the first court's decision in the eavesdropping case filed by law firm Prakken d'Oliveira. The General Intelligence and Security Service (AIVD) had been tapping calls between the firm's lawyers and their clients. In the appeal decision, the judge in The Hague ruled that the AIVD and MIVD (military intelligence) aren't allowed to monitor such phone calls, which are covered by attorney-client confidentiality. Monitoring is only legal under independent supervision, which is currently lacking.
