The city [New York City] will appeal a Supreme Court ruling this week requiring City Hall to release a scathing analysis of the city’s trouble-plagued 911 system.

Fire Department unions have subpoenaed the analysis and all of its drafts but the city has objected to their release, saying the report is not ready for public viewing.

The existence of the report, first denied by City Hall, was disclosed by The Post last week.

On his weekly radio show yesterday, Bloomberg said the damning report, officially called “911 Call Processing Review,” “was just a bunch of stuff thrown together.”

The mayor commissioned the review after the city’s disastrous response to the 2010 Christmas blizzard.
