Maguire played a critical role in the proceedings, as a member of a panel of jurists of activists, politicians, judges and human rights experts. Over two days the esteemed jury heard evidence of the connections between the crimes against Palestinians being perpetrated by Israel on the ground, and the role of international sponsors, particularly the European Union.

For years, Israel has denied Palestine its right to self-determination by occupying its land, waging war on its citizens and blockading them economically. The goal of the Russell Tribunal was to show that Israel has not been alone in its oppression of the Palestinian people. European countries have enabled these actions by giving Israel economic, military and diplomatic support.
