On 13 May 2022, the Association of European Administrative Judges (AEAJ) and the US National Conference of Administrative Law Judges (NCALJ) - American Bar Association (ABA) - concluded a Memorandum of Understanding to provide a framework for their friendly transatlantic relations.

The signature of the original Memorandum was preceded by early contacts between former AEAJ president Edith Zeller and hon. Ed Felter, Alex Manuel and Julian Mann, from the Judicial Division of the American Bar Association.

By signing the renewal of this memorandum on 9 January 2025, the two associations commit, once again, to "mutually promote education and understanding about the work of each other's organizations".

In the framework of this memorandum, AEAJ president Sylvain Mérenne attended to the ABA annual conference in Chicago in July 2024 and made a presentation to US participants on European administrative justice systems.

Hon. Mimi Tsankov was elected chair of NCALJ chair the following day in Chicago.
