Readjustment of the principle of sustainability in administrative law, in particular in environmental and planning law - Reassessing the dogmatics of sustainability following the New Zealand model

可持续发展如今被广泛接受为一项国际规范性原则。尽管其确切的法律含义尚未最终确定，但确保生物系统随着时间的推移保持多样性和生产力的想法已经被引入欧洲法律，部分被引入德国宪法。可持续性也影响到德国的行政法，它本应能够将可持续性融入日常现实，但实际上却显示出缺陷。例如，可持续性只是作为一种抽象的指导原则被提及，而没有法律规范。此外，在价值增值的情况下，可持续发展可以在规划法中被超越(ABWägangsenscheidung)，或者在环境法中往往仅限于其生态领域。因此，本研究项目试图重新解释德国法律的可持续性，以弥补其缺陷。它寻求新西兰法律的支持，因为新西兰不仅通过法定措施而且将可持续性应用于行政和监管的所有领域，从而将可持续发展纳入国内法律。新西兰的独特之处在于，它将可持续性作为一项可执行和积极的原则，这为综合环境管理模式和新西兰环境法院提供了基础。该研究项目旨在受益于新西兰法律在可持续性原则方面取得的理论和实践经验。它的目的是分析技术文献和相关法律案例。所有努力都将导致应用可持续性的模式，使我能够反思德国对可持续性的做法，并为在行政程序中优化应用提出建议。

Sustainability is nowadays widely accepted as an international normative principle. Although its precise legal meaning is not yet finally defined, the idea to ensure that biological systems remain diverse and productive over time has been introduced to European Law and partly to the German constitution. Sustainability also affects German administrative law, which should be in a position to integrate sustainability into everyday reality but which in fact shows shortcomings. For example, sustainability is only mentioned as an abstract guiding principle without legal specifications. Furthermore, sustainability can be overridden in planning law in the event of an appreciation of values (Abwägungsentscheidung), or it is often reduced merely to its ecological domain in environmental law. Therefore, this research project seeks to reinterpret sustainability for German law in order to compensate its deficits. It looks for support in New Zealand law, as New Zealand has incorporated sustainability into domestic law by applying sustainability not just through statutory measures but across the full spectrum of administration and regulation. New Zealand is unique in the way it has created sustainability as an enforceable and active principle, which provides the basis for an integrated environmental management model and the New Zealand environmental court. The research project intends to benefit from the theoretical and practical experiences New Zealand law has gained with the principle of sustainability. It aims to analyse the technical literature and the relevant law cases. All effort shall lead into a model of applied sustainability that allows me to reflect on the German approach to sustainability and to offer proposals for an optimized application within the administrative procedure.
