This article analyzes the recurrent “erosion thesis” in the governance literature, arguing that bureaucratic or procedural public-sector institutions have come to play a less significant role in public-policy formation. Evidence from the Swedish policy-making institutions referred to as “governmental commissions” and adoption of the perspective of interest organizations support the claim. Using various theories of institutional change, I show that increased government control has reduced the influence of governmental commissions on policy, but not eliminated the belief held by interest organizations that the commissions are legitimate institutions.
