NEWARK — With the accreditation of Essex County College on the line, the school is slipping into deeper turmoil as two of its top administrators accuse each other of misusing funds.

Anthony Munroe, president of the college since June 1, wrote to the board of trustees on Sept. 6 asking that Joyce Harley, the vice president of administration and finance, be suspended and investigated for buying a half-million-dollar commercial copier without proper approval. The letter, which was obtained by The New York Times, also said Ms. Harley used school money to pay her personal cellphone bill and took improper leaves.

Ms. Harley denied the allegations and countered, accusing Mr. Munroe of misusing relocation funds to pay homeowner fees and his children’s tuition and to buy a television. Mr. Munroe also denied wrongdoing.

The accusations are the latest controversy in yearslong turmoil among the two-year school’s leadership since the 2010 resignation of its longtime president, A. Zachary Yamba. The continuing conflict has caused the Middle States Commission on Higher Education to warn that the college is in danger of losing its accreditation because it lacks financial controls, has a poor governance structure and conflict-of-interest rules, and struggles to retain students. The school has also been warned by the U.S. Department of Education for submitting late audits.
