Officer Daniel Pantaleo was “untruthful” during his interviews with investigators after the death of Eric Garner, according to an administrative judge for the NYPD — who blasted the Staten Island cop’s repeated chokehold denials as “implausible and self-serving” in a 46-page opinion on Sunday.

“[Pantaleo’s] use of a chokehold fell so far short of objective reasonableness that this tribunal found it to be reckless — a gross deviation from the standard of conduct established for a New York City police officer,” wrote Deputy Commissioner of Trials Rosemarie Maldonado, who oversaw Pantaleo’s departmental trial back in May and June.

“Moreover, [Pantaleo’s] glaring dereliction of responsibility precipitated a tragic outcome,” Maldonado said. “The credible medical evidence and expert testimony demonstrated that [Pantaleo’s] recklessness caused internal hemorrhaging in Mr. Garner’s neck and was a significant factor in triggering the acute asthma attack which contributed to his death.”

Pantaleo’s “egregious misconduct” ultimately led “to the deadly consequences his training anticipated and which the prohibition was designed to prevent,” Maldonado added. “As noted in Disciplinary Case No. 7616112 (March 28, 2017), the tribunal cannot ‘overlook’ the fatal consequences of an officer’s reckless disregard of Department procedure.”

Maldonado’s report was first obtained by the New York Times on Sunday and later confirmed by an official who spoke to The Post.

In it, the judge describes how Pantaleo denied using a chokehold on Garner and acted “disingenuous” when viewing cellphone video of his encounter with him on July 17, 2014.

Pantaleo “denied using a chokehold, even though his actions were completely consistent with his own erroneous and restrictive definition of the Patrol Guide prohibition,” Maldonado said. “The preponderance of the credible evidence contradicted his rationalization that the positioning of his elbow protected Mr. Garner’s neck and that he exerted no pressure to the throat. Specifically, [Pantaleo’s] self-serving version of events failed to satisfactorily account for the uncontroverted medical evidence of hemorrhaging in Mr. Garner’s anterior neck muscles and this tribunal’s own assessment of the video evidence capturing [Pantaleo] clasping his hands and pressing his forearm against Mr. Garner’s neck.”

According to Maldonado, NYPD officers who testified on behalf of Pantaleo were “unhelpful or unreliable.”

“In fact, the more central the factual inquiry was, the more vague recollections became,” Maldonado said. “In sum, having carefully considered the video and medical evidence, in conjunction with witness testimony and applicable NYPD procedure, this tribunal finds that [Pantaleo] used a prohibited chokehold as defined by the Patrol Guide during this physical encounter.”

Maldonado’s report comes as NYPD officials prepare to deliver a decision on whether Pantaleo will be allowed to keep his job. The judge had previously recommended in a non-binding verdict that he be fired. Officials from the Civilian Complaint Review Board have also come out and said Pantaleo used a prohibited chokehold.

“The CCRB has proved its case and recommended termination,” said CCRB chairman Fred Davie in a statement last Wednesday.

Pantaleo was able to dodge criminal and federal civil rights charges back in July — with Attorney General William Barr dropping the case due to “insufficient evidence.” The only punishment he faces now is being fired from the NYPD.

“This tribunal finds that there is only one appropriate penalty for the grave misconduct that yielded an equally grave result — [Pantaleo] can no longer remain a New York City police officer,” said Maldonado.

“ln making this penalty recommendation this tribunal recognizes that from the outset Mr. Garner was non-compliant and argumentative, and further notes that the Patrol Guide allows officers to use ‘reasonable force’ when necessary to take an uncooperative individual into custody. What the Patrol Guide did not allow, however, even when this individual was resisting arrest, was the use of a prohibited chokehold. Having considered relevant precedent, in conjunction with the arguments, caselaw, and evidence presented at trial, it is recommended that [Pantaleo] be DISMISSED from the New York City Police Department.”
