The man whose office issued arrest warrants for Vladimir Putin and Benjamin Netanyahu cannot currently practice law in the country that trained him. The Bar Standards Board of England and Wales has upheld the suspension of Karim Khan, the International Criminal Court's chief prosecutor, following allegations of sexual misconduct made by a female member of his staff. The decision keeps Khan locked out of the English bar at precisely the moment his career at The Hague is hanging by a thread.

The timing is not incidental. The ICC's Assembly of States Parties — the governing body of 124 member nations that collectively oversee the court — is scheduled to vote later this month on whether to remove Khan from office entirely. The Bar Standards Board's ruling lands as a formal institutional verdict, not a media allegation, and it will be impossible for Khan's defenders to wave it away as a political hit job from governments angry about his prosecution choices.

Khan, 56, has served as ICC Prosecutor since 2021 after a career as a prominent international defense and prosecution lawyer. His tenure has been operationally significant: the arrest warrant for Putin over the alleged deportation of Ukrainian children was issued under his watch, as was the controversial warrant application targeting Israeli Prime Minister Benjamin Netanyahu and former Defense Minister Yoav Gallant over the conflict in Gaza — a move that drew furious pushback from the United States, Israel, and several European governments. His supporters have long argued that the misconduct allegations are a manufactured campaign by states that want the court neutered.

That argument is now harder to sustain. The Bar Standards Board is not a geopolitical actor. It is a domestic professional regulator, and its decision to uphold — not merely impose — a suspension signals that it reviewed the underlying basis for the original ban and found it sound. The board does not publicize the full evidentiary record, but the standard for upholding a suspension requires the regulator to be satisfied that the conduct alleged is sufficiently serious to warrant continued exclusion from practice pending a final determination.

The female aide at the center of the allegations has previously given a formal account to ICC investigators. The court's own Independent Oversight Mechanism — the body mandated under the Rome Statute to investigate misconduct by senior officials — has been examining the case. Multiple staff members have also reportedly provided corroborating testimony to that body, according to accounts given directly to the Assembly of States Parties during closed consultations. Khan has denied the allegations and characterized them as politically motivated.

What the ICC faces now is an institutional stress test with no clean exit. If the Assembly votes to remove Khan, the court enters a period of prosecutorial vacuum at a moment when active investigations span Ukraine, Gaza, Sudan, and Myanmar. If it votes to retain him, it does so against the backdrop of a sitting suspension from his own national bar and an ongoing oversight investigation — a posture that will be used by every defendant and hostile government to attack the court's legitimacy for years. There is no good procedural outcome here, only a choice between different kinds of damage.

The broader irony is sharp enough to cut. The ICC was built on the premise that no one — no head of state, no general, no minister — is above accountability. Khan's office has spent three years testing that premise against some of the most powerful actors on earth. The institution is now being asked to apply the same standard to its own leadership, in public, with the world watching. How it handles that is, in a very real sense, the court's most important case right now.

The Assembly of States Parties session is expected to convene before the end of the month. Members have received briefings from the Independent Oversight Mechanism and are operating under ICC rules that require a two-thirds majority to remove a prosecutor. Whether that threshold is met will depend partly on which governments treat this as a matter of institutional integrity — and which treat it as an opportunity to settle scores with a court they have always resented.
