“Charles Hall, a spokesperson for the Administrative Office, told The Post via e-mail that the change was made on Aug. 11 in preparation for an overhaul of the the PACER architecture, including the implementation of the next generation of the Judiciary’s Case Management and Electronic Case Files System. “NextGen replaces the older CM/ECF system and provides improvements for users, including a single sign-on for PACER and NextGen,” he wrote. However, as a result of the changes the locally developed legacy case management systems of some courts were no longer compatible with PACER, he says. Since PACER works as a sort of distributed network of different archives rather than one centralized database, that’s a major problem. However, Hall says, the dockets and documents no longer available through the system could still be obtained directly from the relevant court and “all open cases, as well as any new filings, will continue to be available on PACER.”
