Professor Stephen Hawking is backing the academic boycott of Israel by pulling out of a conference hosted by Israeli president Shimon Peres in Jerusalem as a protest at Israel's treatment of Palestinians.

Israel Maimon, chairman of the presidential conference said: "This decision is outrageous and wrong.
"The use of an academic boycott against Israel is outrageous and improper, particularly for those to whom the spirit of liberty is the basis of the human and academic mission. Israel is a democracy in which everyone can express their opinion, whatever it may be. A boycott decision is incompatible with open democratic discourse."

In 2011, the Israeli parliament passed a law making a boycott call by an individual or organisation a civil offence which can result in compensation liable to be paid regardless of actual damage caused. It defined a boycott as "deliberately avoiding economic, cultural or academic ties with another person or another factor only because of his ties with the State of Israel, one of its institutions or an area under its control, in such a way that may cause economic, cultural or academic damage".
