WASHINGTON, Aug 11 (Reuters) - A group of current and former Palestinian students and staff have sued Columbia University, alleging ‌discriminatory treatment by the school against its Palestinian community since ‌late 2023, according to a court filing in New York.

• The lawsuit said the university ​failed to protect its Palestinian members from harassment and targeted them through what it cast as "unfair and biased disciplinary hearings."

• Columbia has previously denied being discriminatory and has condemned hate. Local media reported that it declined to comment ‌on pending litigation. It did ⁠not respond to a Reuters request for comment.

• Protests took place at Columbia and around the U.S. after the ⁠start of Israel's assault on Gaza following a deadly Palestinian Hamas attack in October 2023.

• Protesters demanded an end to U.S. support for its ally ​and called ​for the divestment of funds by ​universities from companies supporting Israel.

• ‌In May 2025, Columbia suspended more than 65 students for their role in shutting down the university's main library in a pro-Palestinian demonstration.

• That demonstration came as the university was negotiating with President Donald Trump's administration, which had cut its federal funding after accusing the university of tolerating antisemitism ‌during pro-Palestinian protests.

• Protesters, including some Jewish ​groups, say opposing Israel's assault on Gaza ​and its occupation of Palestinian ​territories is not antisemitic and advocacy for Palestinian rights ‌should not be conflated with supporting extremism.

• ​Columbia agreed to ​pay over $200 million to the U.S. government to resolve federal probes and restore most of the federal funding in July last year.

• ​Free speech groups condemned ‌Columbia's protest crackdown in which students faced arrests, suspensions, expulsions and ​degree revocations.
