The European Union first banned Hamas’ military wing, the Izz a-Din al-Qassam Brigades, in 2002, though the organization’s social and political divisions were not put on the terror list. Following a series of Hamas suicide bombings during the second intifada or uprising in September 2003, the EU extended the ban to include the organization as a whole.
On September 12, 2010, Hamas appealed the ban, largely on procedural grounds. In its complaint, the group cited a lack of due process, specifically, that it had not been properly informed the act was being implemented. It further asserted that as a “legitimately-elected government,” it cannot be labeled as a terrorist organization, saying such a designation flies in the face of “the principle of non-interference in the internal matters of a State.”
