This article outlines an approach, derived from Ann and Robert Seidman’s Institutionalist Legislative Drafting Theory and Methodology (ILTAM), for drafting laws and developing implementing policies and programmes to realize legislative objectives and promote necessary behavioural change throughout a jurisdiction despite significant sub-jurisdictional socio-economic differences. ILTAM can serve as a powerful tool for catalysing the development of situationally appropriate programmes to initiate and sustain behavioural change in furtherance of legislative objectives. The article begins by discussing the movement towards legislative standardization, and its benefits and failings. It then introduces the concept of informal jurisdictions, and highlights modifications to ILTAM that improve the methodology’s efficacy in devising solutions that work in those jurisdictions. The article then describes the power of intransitive law as a mechanism for catalysing progress towards shared objectives in a manner that allows for localized approaches, promotes governmental responsiveness, brings innovation, and maximizes participatory governance. Lastly, it describes the importance that Ann and Robert Seidman placed on institutionalizing on-going monitoring, evaluation and learning processes; and describes how intransitive drafting techniques can focus implementation on motivating behavioural change while systematically identifying needed policy and law reforms in response to suboptimal legislative outcomes.
