The Comprehensive Multidimensional Legitimacy Model: A Methodology for Applied Ethics Evaluation, Institutional Diagnosis and Practical Reform Development

This paper develops a comprehensive multidimensional legitimacy model that provides a generic framework for exploring legitimacy in institutions – including the legitimacy of rules, codes, collective activities and organisations themselves. Through the use of 10 dimensions, covering concerns with fairness, efficacy, integrity, expectations, inclusive decision-making and more, the model aims to capture the full suite of distinct features that may be morally relevant in any given case. Each dimension is a continuum and can provide reasons for moral challenge, toleration or pro-active support. The model can be used to diagnose ethical risk areas, to compare reform initiatives and to inform empirical studies of descriptive legitimacy and the social licence to operate. It may also be used as an applied ethics methodology to evaluate overall institutional moral legitimacy; the paper discusses the contextual judgments required for this, including the way that some legitimacy factors can operate as defeaters, such that a serious failure on a pivotal dimension cannot be overcome by support from other dimensions.
