In 2003, Duynhoven raised with the Speaker of Parliament his status, and whether he might have breached electoral law, thus disqualifying him from retaining his seat. The Speaker was responsible for determining whether a vacancy existed. This matter arose after Duynhoven applied to resume his citizenship of the Netherlands. His father was from the Netherlands, and Duynhoven had possessed citizenship from birth, but had temporarily lost it due to a change of Netherlands law. According to electoral law, applying for foreign citizenship would disqualify Duynhoven from retaining his seat. The Speaker ruled on 23 July 2003 that Parliament's Privileges Committee, who were until 2002 responsible for determining whether a vacancy exists, would consider the matter, and that he would be guided by their report. The Solicitor General advised the Privileges Committee that the law was clear, and that Duynhoven's seat became vacant on 11 June 2003. The majority decision of the Privileges Committee was that Duynhoven was disqualified from holding his seat, and that it had accordingly been vacated. However the government introduced an act retroactively amending the law, to allow Duynhoven to resume his seat.
