A letter to Amsterdam’s Federation of Administrators, a committee consisting of the administrators of Amsterdam’s various socialist trade unions. The federation had written to Kuyper about the application of Article 10 subsection 2 of the Appeal Law, which in practice often worked out badly for the appointment of workers as members of boards of appeal. A board of appeal consisted of employers and employees. Kuyper writes that the spirit of the Appeal Law permits the flexible interpretation of this subsection and notes that he has always asked mayors (who were initially responsible for its interpretation) to apply it generously.
