New York’s Court of Appeals is set to review the first in a potential steady stream of suits challenging the broad application of a law shielding certain documents in the personnel files of police officers and other public employees from public exposure.

The suit, filed by the New York Civil Liberties Union, will be the biggest civil liberties test yet for the young court. All the judges were appointed under the current governor, Andrew Cuomo, with the longest-serving judge, Jenny Rivera, having been on the bench for less than four years.
