A battle for a district that includes parts of northern Westchester, Putnam and Dutchess.

New York State Sen. Terrence Murphy engaged in “unfair” campaign practices in his race against Democrat Pete Harckham, a nonpartisan committee found.

The Westchester County Fair Campaign Practices Committee issued four findings in a report released Sunday, saying Murphy made unsubstantiated and misleading claims including a “knowing mischaracterization” of one of the committee’s previous rulings.

Murphy, a Yorktown Republican, is seeking his third two-year term in the Senate’s 40th District, which includes parts of northern Westchester, Putnam and Dutchess counties. Harckham, of Lewisboro, is a former county legislator and worked in the administration of Gov. Andrew Cuomo.

Murphy’s campaign has contends the final ruling was based on an inaccuracy that A-Home wasn’t involved in the Conifer project. A-Home Community was listed as the nonprofit for its project in media, but later changed its name to Allied Community Development.

The nonpartisan committee has the stated purpose to promote honesty and fairness in campaigns. Campaigns may choose to issue complaints to the committee, which may then rule on whether the complaints are fair or unfair.

Its rulings aren’t binding.
