IACL: The International Association of Constitutional Law

The overriding objective of the International Association of Constitutional Law (IACL) is to provide a forum in which constitutionalists from all parts of the world can begin to understand each other’s systems, explain and reflect on their own, and engage in fruitful comparison, for a variety of purposes.

L'AIDC: l'Association Internationale de Droit Constitutionnel

L’objectif premier de l’AIDC est d’offrir un forum dans lequel les constitutionnalistes du monde entier puissent commencer à comprendre le système constitutionnel de chacun, expliquer et réfléchir par eux-mêmes, et se livrer à des comparaisons fructueuses, dans des buts variés.

Blog

Launched in 2018, the IACL-AIDC Blog aims to provide a user-friendly meeting place for constitutionalists around the world to present their research, share their views, and discuss crucial constitutional law topics, as well as overlooked issues and more technical discussions of constitutional law. The five values of the Blog are to be user-friendly, provide added value, and to be responsive, inclusive and truly global.

Constitutions Studies - the IACL journal

In 2025, the IACL and the Comparative Constitutions Project partnered to relaunch Constitutional Studies as an international multilingual, open access journal, publishing work on the theory and practice of constitutional government around the world. The journal engages scholars across diverse regional, linguistic, and disciplinary boundaries to expand our collective understanding of constitutional issues.

Establish a new IACL Research Group

Thematic Research Groups are a very special part of the IACL. Although hosted by, and therefore existing under the umbrella of the IACL, these Research Groups operate independently. They conduct research and publish findings, and they organise private meetings, public events and other activities. They contribute richly to the identity and reputation of the IACL and benefit from the IACL’s affiliation and endorsement.

National Associations

The IACL endeavours to ensure that its processes and activities are suited to its diverse membership, whilst at the same time retaining the scientific and scholarly approach on which the credibility of its work depends. The IACL maintains close links with many national and regional associations of constitutional law.
