In the western context, law has two functions. It upholds normative expectations and it transforms social phenomena. The latter is expressed through the form-giving function of law, as law designates particular social phenomena, such as, for example, economic, political or religious. Inside such overarching categories, further subcategories can moreover be observed. In relation to economic processes, the legal institutions of competition, contract, corporation and property are, for example, classical examples of the form-giving function of law. The dual function of law is briefly illustrated through a genealogy of imaginaries of law distinguishing between four historically dominant types of law: ‘Law as purpose’; ‘law as a tool’; ‘law as an obstacle’; and ‘law as reflexivity-initiation’. On this background, ten core dimensions of what might become a new episteme of transformative law are fleshed out with the aim of answering the question to what extent it can act as an alternative to the previous four types of law.

The rule of law has emerged both on the domestic and international levels as a promise of longstanding democracy, economic development and peace. On both levels, the rule of law is often associated with the longstanding character of institutions and the predictability of rules, meaning that ‘citizens are entitled to laws that are neither murky nor uncertain’. However, does this always mean in practice that the rule of law can only be concretized by laws and legal institutions that last forever? More specifically in the international context, can we guarantee the consolidation of the international rule of law through the coexistence of both permanent and temporary institutions and instruments? In this chapter, I analyse the meaning of the rule of law at the domestic and international levels and discuss its complex relationship with time. I argue that the past, present and future of the rule of law can be, in some cases, united by the use of temporary institutions such as international criminal tribunals or truth commissions, rules and measures. Temporariness can be essential to react swiftly to humanitarian crises, provide transitory justice, gradually concretize the rule of law in fragile democracies, and adapt legal orders to evolving economic and political circumstances.
