This chapter examines how the same complex dynamics that shape FOI formulation continue after the passage of legislation. This chapter looks across the country cases, beginning with the UK, to see how FOI interacts with its wider environment and new ideas around openness (Posen 2013). It examines thematically the role of various, sometimes competing and contradictory, influences on the legislation post-implementation: including high profile scandal Lock-in of FOI legislation with the gradual ‘normalising’ of openness systems within bureaucracies over time, assisted by the integration of independent appeal bodies, helping to entrench FOI within systems as an ‘everyday’ activity (Hazell and Worthy 2010: Kimball 2012). It looks at attempts to strengthen FOI and attempts to weaken FOI. The chapter ends by mapping out the complex dynamics and pattern of post –implementation FOI. It examining what groups (government factions, users, media) and what events, both real and symbolic, (crisis, electoral victory, reform programmes) can help trigger the different dynamics and how they can change (Hillebrandt, Curtin and Meijer 2012).
