In 1997-1998 Biletzki helped establish the human rights movement “Open Doors” which worked on the problems of administrative detention in Israel. She has also been active as one of the leaders of Hacampus Lo Shotek – “The Campus Is Not Silent” – at Tel Aviv University, and was on the board of FFIPPI-Faculty for Israeli-Palestinian Peace. She was chairperson of the board of B’Tselem – the Israeli Information Center for Human Rights in the Occupied Territories – during the second intifada (2001-2006). In 2005 she was chosen as one of “50 most influential women in Israel” by Globes, the Israeli business monthly, and was nominated among the “1000 Women for the Nobel Peace Prize 2005”.
