The case, filed in Manhattan federal court Monday, follows reports from around the country last month of Jewish and pro-Israel groups who said their planned transportation to and from the November 14 rally in the nation’s capitol fell through at the last minute. Hundreds of people, affiliated with several different groups from Detroit, New York, Connecticut and other regions, were reported stranded, which they allege was a coordinated effort motivated by antisemitism. New York groups said they were never picked up; groups from Detroit said they were unable to get to the rally once they landed at Washington’s Dulles airport.

The lawsuit was filed on behalf of two Jewish New York residents and a travel company that chartered the bus service. It is seeking certification as a class action, which if granted would allow it to potentially represent groups of people across the country who lost out on transit service that day.

The lawsuit accused US Coachways of Staten Island, New York, of civil rights violations, negligence and breach of contract. US Coachways operates a national network of transit service providers delivering people to tens of thousands of events per year. Company representatives did not respond to requests for comment. Other bus companies have also been sued over the allegations, and it was not clear that US Coachways was the service provider in all of the instances.

The New York plaintiffs allege they paid nearly $19,000 to Coachways to charter five buses that day to Washington, D.C. But the buses never arrived at the pick-up points, and the passengers were notified minutes before they were scheduled to leave that the charters had been canceled because of scheduling errors, driver availability and other reasons.

In fact, the complaint claimed, drivers coordinated the walk-out through text messages, calls and emails to prevent the protestors from getting to the rally.
