Left-wing group the Socialist Alternative was deregistered as a club by the Monash University Student Association on Tuesday, the same day a student from the same group at La Trobe University was threatened with expulsion following allegations of harassment of a Jewish student on campus.

The Monash association has simply said the Socialist Alternative is "prejudicial to the interests of clubs and societies", but the Socialist Alternative has blamed a recent article by Education Minister Christopher Pyne to The Australian calling on universities to respond to increasing anti-Semitic behaviour on campus.

The deregistration would mean the group can no longer hold political meetings or information stalls at Monash University's Clayton campus.

Socialist Alternative member Sarah Garnham, said the delisting was an "extremely harsh measure" and the group has said it would consider pursuing a legal case against the Monash Students Association.

The events at Monash University follow investigations by La Trobe University into allegations of harassment and intimidation of a Jewish student on campus.
