This article explores the different ways governments express dissent in the Council of the European Union (EU) through ‘No’ votes, abstentions and recorded negative statements. A game‐theoretical model is presented that studies voting behaviour and analyses how the national parliaments’ levels of control over their governments’ EU policies affect it. It is concluded that governments that are strongly controlled by their parliaments are not more likely to express dissent. However, when they do express dissent, they vote ‘No’ more often. Parliamentary control depends on the presence of formal oversight institutions as well as the motivation of parliamentarians to hold their governments accountable. Empirical support is found in an analysis of votes on 1,387 legislative proposals that represent more than a decade of Council decision making in the period 2004–2014. This article contributes to the discussion on the involvement of national parliaments in EU affairs, and clearly distinguishes the different forms of dissent in Council decision making.
