In a comment piece for Le Monde he suggested the activists were "taking advantage of academic freedom" and criticised the organisers for the misuse of the term "academic conference". He also cited cases of antisemitism, including graffiti and signs equating a star of David with a swastika, affecting Jewish students at the university, as reasons for his decision.
"Mobilising for a political solution for the freedom of the Palestinian people…deserves better than this controversy," he said.
The activists went to the Paris courts to overrule the university's decision, but their request was rejected. However they stated that they would ignore Prof Binzac and hold it on campus anyway, prompting the university management to announce the closure of the university for the duration.
In a statement, the management said that the activists' dedication to "a radical" approach had forced "the worst decision".
They said the "highly polemic nature" of the event could have led to "disturbances to the public order."
