Purpose This study aims to explore how corporate discourses enact legitimation strategies aimed at repairing pragmatic, moral and cognitive legitimacy types (Suchman, 1995) after a scandal involving sustainability, namely, the Volkswagen’s 2015 diesel scandal. Design/methodology/approach By drawing on the discursive nature of legitimacy, this study conducts a critical discourse analysis to identify how the scandal is depicted and which semantic, grammatical and lexical features characterise discourses. It then relates discourses and their features to legitimation strategies that help repair diverse types of legitimacy. Findings To repair pragmatic legitimacy, discourses on a few actors and processes enact strategies of creating monitors and avoiding panic. Such discourses include grammatical features only. Discourses on the event, actors, processes and topics of apology, trust and integrity aim to repair moral legitimacy. Enriched with grammatical and lexical features, they mobilise disassociation, excuse, justify and restructure strategies. Discourses on the event, actors, processes and topics of corporate qualities, history and future strategy help repair cognitive legitimacy by enacting an avoiding panic strategy. Grammatical, lexical and semantic features characterise such discourses. Research limitations/implications The study reveals the potentials of critical discourse analysis to bring out from texts practical modes of communicating, and specifically those discourses and features of discourses that serve legitimacy purposes. Originality/value This study offers insights into the connection among discourses, relegitimation strategies and legitimacy types by combining the discursive nature of legitimacy with critical discourse analysis. It also contributes to the growing literature on how organisations face the legitimacy challenges raised by scandals involving sustainability.
