Assembly of States Parties to the first bench of the ICC. She was one of seven women and the only judge elected from the Eastern Europe group. She was sworn in at the inaugural session of the court on March 11, 2003. After this first election of judges to the ICC, the President of the Assembly of States Parties drew lots to assign the eighteen judges to terms of three, six or nine years. Only the judges who received terms of three years were eligible for re-election. Ušacka, having received a three-year term, was therefore eligible for re-election, and was subsequently re-elected in 2006 (with the highest number of votes, 77 from 100). Her non-renewable nine-year term expired in 2015. Upon their inauguration to the ICC in 2003, the ICC judges were assigned to judicial divisions. During her first term, Ušacka was assigned to the Trial Division. However, from 2007 to 2009, she was temporarily attached to Pre-Trial Chamber I, which presided over the second ever confirmation of charges hearing at the ICC in the case of the Prosecutor v. Germain Katanga and Mathieu Ngudjolo Chui. During the period of her temporary attachment to Pre-Trial Chamber I, this Chamber was also the first of the ICC to issue a warrant of arrest for a sitting head of state, in the case of the Prosecutor v. Omar Al Bashir. In March 2009, Ušacka was reassigned by the plenary of judges to the Appeals Division where she served for six years. From April 2011 to March 2012, she has been the Appeals Division's president. During her whole tenure as an ICC judge, Ušacka issued several strong and much noticerd dissenting opinions, namely in the cases Lubanga (https://www.icc-cpi.int/RelatedRecords/CR2013_04193.PDF), see pages 17–22, Nourain and Jamus (https://www.icc-cpi.int/RelatedRecords/CR2012_06628.PDF), Libya (https://www.icc-cpi.int/RelatedRecords/CR2014_06758.PDF), Kenya-Ruto (https://www.icc-cpi.int/RelatedRecords/CR2013_07732.PDF), Kenya-Kenyatta (https://www.icc-cpi.int/CourtRecords/CR2011_16047.PDF), Lubanga (https://www.icc-cpi.int/RelatedRecords/CR2014_09850.PDF), and Al-Bashir (https://www.icc-cpi.int/CourtRecords/CR2009_01517.PDF, after page 95) Activities Ušacka has lectured and published extensively in various fields of law, including public law and administration, international and comparative law, international criminal law and human rights, see in particular the following publications: “The International Criminal Court in Action: Challenges in Fighting Impunity”, IUS NOVUM, no. 1 (2014), pp. 11–45. “Promises Fulfilled?
