The state Court of Appeals on Monday upheld the conviction of political consultant John Haggerty for siphoning $750,000 from the 2009 re-election campaign of then-New York City Mayor Michael Bloomberg.

The 6-0 decision tossed Haggerty’s appeal after he was convicted in 2011 and sentenced to 1-1/3 to 4 years in state prison.

Haggerty, a well-known operative in Republican circles, had received a $1.2 million from the mayor earmarked for the Independence Party to help with security for ballots on Election Day.

It was later revealed Haggerty only spent a fraction of that money for poll watchers, and his lawyers later said he used the money to purchase his childhood home in Queens.

Haggerty’s effort for a new trial centered on whether it was improper for a lower court judge to allow testimony from an official from the trust who had provided Bloomberg’s $1.2 million payment.

But the state’s highest court determined in its ruling the official didn’t impact the lower court jury’s decision.
