Book excerpt: Countless interest groups representing governments and civil societies try to lobby the European Union effectively in pursuit of the desired legislation, subsidies and more. This book describes the everyday practice of lobbying in Brussels, drawing on extensive research and the author's personal experience. The objective of these interest groups is to influence the EU decision-making, of which they see themselves as a stakeholder. To the existing representative bodies such as the Parliament and the Council, they add their practice of lobbying for a desired outcome by making their interests present or represented at the EU level. In a roundabout way, they contribute to the EU integration and also to its democracy, so long as the following conditions are fulfilled.
