The ACLU, Americans for Peace Now, Center for Constitutional Rights, Foundation for Middle East Peace, and Palestine Legal, along with 37 other organization signatories, wrote a letter expressing strong objection to the reference to the “International Holocaust Remembrance Alliance (IHRA) working definition of antisemitism” in proposed American Bar Association resolution 514 (Resolution 514). Addressed to the co-sponsors of the proposed resolution, the letter explains how the IHRA definition has been continually instrumentalized to delegitimize critics and criticism of Israel and its policies, as well as suppress voices and activism in support for Palestinian rights. Consequently, any embrace of the IHRA definition by the ABA would undermine fundamental rights of free speech, freedom of assembly and protest, and academic freedom. Moreover, the reference to the IHRA definition in the ABA resolution would undermine the ABA’s own ability to engage on key issues related to Palestinian rights, including in support of human rights defenders who are increasingly under attack.
