Academics from the University of Sydney are protesting against the bestowal of an honorary doctorate on John Howard, saying the former Prime Minister is "considered a racist and a war criminal" and "not a fit recipient of the university's highest honour".

The university said it is conferring the honour "in acknowledgement of his achievements including world-leading gun law reform, leadership in East Timor and contribution to Australia's economic reform".

But about 112 academics from the university had by Wednesday afternoon signed a petition opposing Friday's planned ceremony with Chancellor Belinda Hutchinson.

"To confer a doctorate on him is an insult to Indigenous people, refugees, and anyone committed to multiculturalism, peace and social progress in this country and in the world," the petition says.
