In 2016, Wolf, Justice Richard Goldstone, former Justice on the Supreme Court of South Africa and chief prosecutor of the International Criminal Tribunal for the Former Yugoslavia and the International Criminal Tribunal for Rwanda, and other colleagues, formed Integrity Initiatives International ("III", pronounced "Triple I"). III is a Boston-based non-governmental organization, which works to establish an International Anti-Corruption Court (IACC) and to promote other measures to strengthen the enforcement of criminal laws against kleptocrats. Wolf proposed an IACC in articles for the Brookings Institution and The Washington Post in 2014. He further developed the IACC proposal in a 2018 paper titled, "The World Needs an International Anti-Corruption Court," and in a 2022 paper titled “The Progressing Proposal for An International Anti-Corruption Court”, which he co-authored with Justice Richard Goldstone and Professor Robert Rotberg.
