An appeals court today upheld the firing of the MTA’s former security chief for insubordination stemming from a corruption probe.

The U.S. Second Circuit Court of Appeals unanimously tossed claims by Louis Anemone that the transit agency acted against him for blowing the whistle on widespread wrongdoing.

The decision says “any reasonable jury would have to find that Anemone would have been suspended and then terminated even absent any retaliatory intent on defendants’ part engendered by his allegedly protected speech.”

Anemone, formerly the NYPD’s chief of department, was axed in 2003 after publicly charging that officials were impeding corruption investigations and undermining efforts to safeguard the rails against terrorism.

The Manhattan appeals court noted that Anemone “routinely disregarded the chain of command” and “either recklessly misled or outright lied to his superiors” regarding a non-existent confidential informant.

Anemone’s lawyer, Matthew Brinckerhoff, said it would be “tragic” if Anemone doesn’t get his day in court, noting that his allegations of improper “wining and dining” of then-LIRR President Kenneth Bauer by a contractor were later confirmed by the MTA’s inspector general.

“We’re disappointed and were evaluating our next steps,” Brinckerhoff said.
