Book excerpt: A radical, empirical investigation of how national courts 'react' to disputes involving international organizations. Through comprehensive analysis of the attitudes and techniques of national courts and underlying political motives, Professor Reinisch first describes various legal approaches that result in adjudication or non-adjudication of disputes concerning international organizations. Secondly he discusses policy issues pro and contra the adjudication of such disputes. His study then scrutinizes the rationale for immunizing international organizations from domestic litigations, especially the 'functional' need for immunity, and substantially debates the implications of a human rights-based right of access to court on immunizing international organizations against national jurisdictions. Finally he identifies contemporary trends, seeking to ascertain whether a more flexible principle exempting certain types of disputes from domestic adjudication might substitute for the traditional immunity concept, which would simultaneously guarantee the functioning and independence of international organizations without impairing private parties' access to a fair dispute settlement procedure.
