Open Letters — Emails between Newark Mayor Cory Booker and Facebook founder Mark Zuckerberg about his $100 million donation to the city’s schools are subject to disclosure under the Open Public Records Act, a state judge ruled Thursday.

The documents aren’t entitled to executive or deliberative privilege because they don’t relate to Booker’s decision-making role and were written after the gift was accepted, Essex County Superior Court Judge Rachel Davidson ruled in a suit by a parents’ group backed by the American Civil Liberties Union of New Jersey.
