CONCORD — Police personnel files did not magically become public records last week, despite a New Hampshire Supreme Court ruling that threw out a 27-year-old legal precedent that had kept them locked away from public access, lawyers in the case said.

Anyone who wants access to the personnel file of a police officer or any public employee will have to show good reason, most likely to a judge, why the file should be open, according to Gilles Bissonnette, legal director of ACLU New Hampshire, which prevailed in the two decisions.
