The article assesses dynamics of regulation on parties in Hungary by distinguishing between periods of consensus characterised by a cartel-party effect and periods of conflicts characterised by a dominant-party effect. The relative stability of the party system until 2010 makes Hungary a good case to study the growing rigidity of regulation along with increasing disregard for legal constraints. The resulting loss of credibility along with the changing political logic gave way to the emergence of self-centred party regulation, which could not address the main caveats of the regulatory framework and could easily undermine the party system's stability.
