Abstract

Recent scholarly attention to ‘legitimate expectations’ and their role in legal transitions has yielded widely varying principles for distinguishing between legitimate and non-legitimate expectations. This article suggests that methodological reflection may facilitate substantive progress in the debate. Specifically, it proposes and defends the use of a wide reflective equilibrium methodology for constructing, justifying and critiquing theories of legitimate expectations and other kinds of normative theories about legal transitions. The methodology involves three levels of analysis — normative principles, their theoretical antecedents, and considered judgements about their implications in specific cases — and iteration between these three levels in an effort to ensure coherence. The payoffs from applying this methodology to the legitimate expectations debate are illustrated through a discussion of examples from the existing literature. Some proposed innovations to the methodology, including the incorporation of insights from the ideal/non-ideal theory debate, are likely to be of wider interest to political theorists.
