Both Kirchheimer and Neumann were active as lawyers in the later 1920s and early 1930s, the latter especially having a close connection with trade union legislation and labour law. From their viewpoint as Social Democrats and lawyers they present incisive analyses of the problems confronted by the attempt to realize the ideal of a social in a political environment increasingly dominated by forces on left and right which saw constitutional order only as a means to seize power, and not as a legitimate form of order in itself. In these circumstances, political issues translated into constitutional issues, and thus could be analysed in terms of the aims and objectives of a given constitutional order. A substantial introduction by the volume’s editor, Keith Tribe, presents the political and theoretical background to these essays, which range over questions of industrial democracy, political representation, parliamentary rule and the role of judicial review. These issues are once more on the political agenda of Western industrial democracies, and the analyses of Kirchheimer and Neumann have lost none of their force and relevance, despite the catastrophic ‘failure’ of Weimar democracy in 1933.
