In a 4-2 decision, New York’s highest court agreed with two lower courts that New York City’s attempted ban on sugary drink portions over 16 ounces exceeded the powers of the city’s Department of Health. [Bloomberg News coverage]

That’s exactly in line with what I wrote at earlier stages of the case. At the time, some national commentators did not seem to have checked out the actual reasoning of Judge Milton Tingling’s decision, which rested squarely on a distinctive 1987 New York precedent called Boreali v. Axelrod which had struck down the state health department’s attempt to regulate smoking in public places as beyond its properly delegated authority. The soda case was (as they say) on all fours with Boreali, and although the Court of Appeals could have overturned Boreali, as some academics urged, or found grounds to dodge its effect, as the two dissenters did, the court instead chose to apply the precedent as it stood. That confirms that the Bloomberg-appointed Board of Health, in its eagerness to assert powers not rightly its own, had casually broken the law.

One of the two dissenters was Chief Judge Jonathan Lippman, the latest of many indications that he is inclined to pull the Court of Appeals away from many of the positions and habits that have given it a centrist reputation among state courts.
