Cooperation between public and private actors are becoming more common and it means that the public sphere is organized differently than before. The new form of control is carried out through horizontal relationships, as a result governance. A form of governance is the PPP (private-public partnership), which involves public and private actors getting together to solve problems. In order to explain the relation between PPP and Elster triangle dilemma I have chosen to make an empirical case study of the development Strängnäs Business Park (SBP) in Strängnäs. I have studied three high-ranking roles involved in the project. I have used a theoretical interpretation and the starting point of the essay has been the interviews and SBP development plan. The study is based on two issues that is to understand how the different actors understand the partnership and what relationships they have to Elster three requirements (democracy, efficiency and the constitution). The results of the study show that the different actors have diverse interpretations of what a partnership is and who the partners are. The result also shows that SBP today work more with efficiency than democracy and the rule of law.   Keywords: Governance, partnership, public-private partnership (PPP), constitutional, efficiency, democracy
