Advanced Advocacy Training

On 3-4 June 2023, IILAT organised a 2-day Advanced Advocacy Training course for mid-level and senior advocates, in partnership with the Honourable Society of the Inner Temple (UK). 

The training brought together a dynamic blend of 18 experienced prosecutors, defense and victims’ counsel from all over the world.

Participants focused on enhancing advocacy skills in all areas associated with a criminal trial, in small groups, under the guidance of experienced trainers. The Training Faculty for the course included a judge of the international criminal court, senior UK barristers and senior lawyers, all of whom have extensive experience in teaching advanced advocacy.

The training was free of charge and was held in person at the premises of the International Criminal Court (ICC) in The Hague.

Advocacy Training for Junior Lawyers

​IILAT organised the Advocacy Training for Junior Lawyers on 10-11 December 2022 in The Hague. We received a total of 103 applications, more than seven times the places available. This demonstrates the interest in and need for this type of trainings in The Hague.

The training was aimed at young practitioners with no or limited experience in the courtroom. We welcomed 12 trainees of 11 different nationalities who are practising in The Hague, either with the Prosecution, Defence, Legal Representatives of Victims or working as legal officers with the judges. They were taught about and practised the skills of examination and cross-examination of witnesses, using a mock case scenario.


It was an excellent opportunity for junior lawyers to improve their advocacy skills with the help of some of the most experienced and respected advocates in the field of international criminal law and interact with fellow legal professionals from different institutions in The Hague. 

The trainers at the event were Joanna Korner KC, Simon Laws KC, Douglas Stringer KC, Beti Hohler, Kamran Choudhry and Leonie von Braun.

Workshop: Witness Preparation

On 28 November 2022, IILAT held a succssful workshop on how to prepare witnesses for trials before international criminal courts and tribunals. The workshop explored what practitioners can do to ensure that witnesses provide relevant, accurate and structured testimony. It also explored the differences in approach when preparing vulnerable witnesses.


The workshop was a hybrid (online) event that took place at the International Criminal Court. It was provided by:

  • Elizabeth Geddes - former US Federal Prosecutor who spearheaded the successful prosecution of R.Kelly in New York and is a founding partner of the law firm, Shihata and Geddes LLP

  • Nicole Samson - Senior Trial Lawer with the Office of the Prosecutor at the International Criminal Court

Thank you to Liz Geddes and Nicole Samson for sharing their experience with legal practitioners and talking about best practices.

The IILAT 2022 Debate

On 3 October 2022, IILAT held its annual debate which addressed a topic that has for years divided international legal practitioners from all sides of the courtroom: witness preparation. 


An esteemed panel comprised of His Honour Judge Bertram Schmitt, Her Honour Judge Joanna Korner CMG KC; Ms. Brenda Hollis and Mr. Rodney Dixon KC debated whether "failing to prepare is preparing to fail?".  The panel discussed the advantages and disadvantages of witness preparation in international criminal courts and tribunals. They also considered how witness preparation should be conducted in cases where it was permitted.

IILAT Workshop with Haitian Lawyers

On 9 September 2022, IILAT Directors Johann Soufi and Julian Elderfield led a workshop, facilitated by Avocat sans frontières Canada, with Haitian lawyers from the Bar Association of Haiti.

The interactive session focused on human rights violations in Haiti and potential legal avenues to accountability at the local and international level.

The IILAT Directors shared their views on the likelihood of a variety of mechanisms, including their pros and cons.

IILAT’s First Training the Trainers Course

From February 19-20, 2022, in collaboration with The Honorable Society of the Inner Temple, IILAT conducted an exclusive “Train the trainer” event at the International Criminal Court in The Hague titled: Advocacy in the international Courtroom. ​

The purpose of the training was to train six experienced lawyers and judges in the use of the Hampel method, a recognized and effective tool for teaching oral advocacy. ​ Trainees came from three international jurisdictions in The Hague: the International Criminal Court (ICC), the Kosovo Specialized Chambers (KSC) and the International Residual Mechanism for Criminal Tribunals (IRMCT).

Nine other lawyers were given the opportunity to act as Counsel during the training. ​The training was delivered by Her. Hon. Justice Joanna Korner CMG QC, Justice Martin Griffiths and Rehana Azib QC.
