Expert contributors ask in what way expert bodies are subject to some of the key pressures in contemporary governance, such as democratisation, politicisation and expertisation. Based on empirical studies, the book traces the multiple social ties of expert bodies and refines the common perception of expert bodies as ‘de-politicised’ institutions that are detached from political interference and societal input.
