Competing for consultation: Civil society and conflict between the European Commission and the European Parliament.

This article investigates how informal rules in the European Union change in the periods between formal treaty revisions. On the basis of a case study on the White Paper on Governance presented by the European Commission in July 2001, it shows how institutional change is driven by conflict between the Commission and the European Parliament. The conflict concerns the development of informal rules to structure the interaction of the Commission and the Parliament with Europe's civil society. The interaction with civil society organisations is very important for the EU bodies because it allows them to acquire resources that are indispensable in order to fulfil and expand their organisational role. An additional aim of this article is to examine how these institutional developments might influence the long-term development of formal treaty rules. [ABSTRACT FROM AUTHOR]
