Who enforces the rules of politics?

Why do politicians sometimes listen to just one colleague when things get tense in the House of Representatives? And how is it that some MPs, across political divides, command authority when it comes to the rules of democracy?
These questions are central to the research project ‘Source of Authority. The role of Members of the House of Representatives as the “constitutional conscience”’. Boris van Haastrecht explores the unique role of MPs who are bestowed this honorary title by parliament. These are politicians who use their in-depth knowledge of procedures, rules and traditions to safeguard the functioning of the House of Representatives – often regardless of their own political affiliation.
One such recent ‘constitutional conscience’ is, for example, SGP MP Kees van der Staaij, and in the 1950s that honour fell to VVD politician Piet Oud. What is it that gives these particular people authority? And how do they contribute to upholding – and sometimes even restoring – the rules of democracy?
Why this research is particularly relevant now
The project runs from 2026 to 2029 and comes at a time when trust in political institutions and the handling of rules is increasingly a subject of debate. “Precisely now that informal rules and customs are under pressure, it is important to understand how they work in practice,” says Van Haastrecht.
The research looks not only at what is formally laid down, but also at the unwritten rules of the political game. By combining biographical research on MPs with parliamentary historical and constitutional analysis, a rich picture emerges of how authority is established in politics.
Broader insight into democratic practice
The findings of the project offer new insights into how democratic institutions function behind the scenes. What role do individuals play in this? And how can they contribute to the stability and reliability of the political system?
The research is supervised by Prof. Dr. Carla Hoetink (Director of DNPP) and Prof. Mr. Dr. Solke Munneke (SBB). The Staatsman Thorbecke Programme Fund is providing 200.000 euro's for the research project.
With this project, the faculty is making an important contribution to understanding the foundations of our democratic constitutional state – and the people who safeguard those foundations.
