A former city principal has been out of work for months because he was falsely accused by a district superintendent of turning a school protest into a “riot,” he claims in a lawsuit.

Everett Hughes, 63, had been working for the Center for Educational Innovation since 2011 — a job that required school access.

On Sept. 17 last year, he attended a demonstration at IS 292 in East New York, Brooklyn, where parents protested the removal of a principal. Hughes claims he observed from the parking lot of the school, while parents rallied in front. District 19 Superintendent Joyce Stallings-Harte drove by.

Before he knew it, Hughes charges in the Manhattan Supreme Court suit against the city, he was fired because Chancellor Carmen Fariña banned him from schools.

Stallings-Harte told Fariña that Hughes “orchestrated” the protest and “caused a riot,” Hughes claims.

“None of these things were true,” he says.
