Switzerland’s Candidate for Judge of the International Criminal Court 2027–36

"

Over 25 years in international criminal justice in all major international criminal tribunals.

A career devoted to law as well as independent and fair decision-making.

Justice must be consistent, effective and principled — especially when the stakes are high. For over 25 years, I have dedicated my career to international criminal justice. I have served in the ICC and every major international criminal tribunal, working on some of the world’s most complex and sensitive criminal cases. These experiences shaped my firm belief in a court that delivers fair, independent, impartial and high-quality justice for victims and communities affected by the gravest crimes.

If elected, I will bring to the ICC:

  • Integrity in decision-making and high ethical standards
