'The 'one in, one out' principle - A real better lawmaking tool?' published

6 November 2023

The study was written by Professor Helen Xanthaki, member of the UCL Faculty of Laws. It was commissioned and edited by the European Parliament's Policy Department for Citizens’ Rights and Constitutional Affairs.



The 'one in, one out' principle - A real better lawmaking tool? proposes that the EU's ‘one in, one out’ policy, which aims to reduce regulatory burdens for businesses, is "a tool for less, not better, regulation and legislation, and, as such, it is not a suitable instrument for better law-making."

Professor Helen Xanthaki is a leading expert in legislation, legislative drafting and legislative quality in the UK, the Commonwealth and the UK. She is a consultant to governments and international and regional organisations both as a trainer and a drafter.

Prof. Xanthaki's research focuses on the quality of EU legislation and of transposition. Her latest study was commissioned by the European Parliament’s Policy Department for Citizens’ Rights and Constitutional Affairs at the request of the Committee on Legal Affairs (JURI).

Beyond submitting that the current 'one in, one out' regulatory model is not suitable, the study posits that "to achieve effectiveness of legislation, the EU must reform its law-making policy holistically by placing the citizen at the core of its legislative communication. Prof. Xanthaki also calls for the formation of a "Working Group dedicated to Better Regulation, to assure a constant reflection on better regulation with the support of a network of European academic experts."

Helen Xanthaki is a Professor at UCL's Faculty of Laws.
