This publication has been drafted by Dr. Fotios Fitsilis of the Hellenic Parliament and Prof. George Mikros of Hamad Bin Khalifa University. It provides an overview of the results of a European Union (EU) funded study entitled “Overview of smart functionalities in drafting legislation in LEOS”. The full study has been published on the European Commission's (EC) Joinup platform and centres on the concept of smart functionalities in law-making, i.e., advanced Information (and Communication) Technologies (I[C]T) services that assist legal drafters and policy developers in their daily work. The underlying research was conducted in view of the development of an “augmented LEOS”, an open-source solution developed by the EC for drafting legislation. The work draws on the results of a 2022 study on “Drafting legislation in the era of AI and digitisation”, referred to as the reference study. The present study offers a thorough examination of various development steps of the "augmented LEOS" system. It confirms, updates, and expands upon the findings of the reference study. Moreover, it provides a detailed assessment of the business value associated with the proposed smart functionalities. The prioritisation of these functionalities is carried out based on their perceived business value. Furthermore, the study conducts an in-depth investigation into the implementation of these functionalities, addressing their deployment. Additionally, recognising the emergence of Large Language Models (LLMs), the study explores their utilisation in drafting legislation. In this context, potential implications and applications of LLMs in the legislative processes are analysed. Finally, the study suggests a high-level framework and roadmap for further work, outlining the necessary steps and milestones for the successful realisation of the augmented LEOS system.
