A man​ who has been in jail for 26 years ​based on a case made ​by discredited ​NYPD ​homicide Det. Louis Scarcella will get a new murder trial, a judge has ruled.

Brooklyn Supreme Court Justice Desmond Green found that there is “reasonable probability” that the confession Scarcella allegedly elicited from Shabaka Shakur in the 1988 double-murder case “was indeed fabricated,” according to court papers.

Green also said “certain witnesses were found to be more credible than others” in granting Shakur a new trial.

Shakur, 50, was found guilty​ at trial​ and sentenced to two consecutive 20-to-life terms.

Scarcella’s reputation as a star homicide detective has been tarnished by allegations of rampant misconduct, including coaching witnesses, made-up confessions and using a crack-addicted prostitute as a witness in multiple murder cases.

So far, convictions in six Scarcella-involved cases have been overturned and some 7​​0 others are under review.

Green said the “new evidence” of Scarcella’s decades-old wrongdoings and his “propensity to embellish or fabricate … necessitates a new trial” in Shakur’s case.

“We are extremely grateful to the court for a full and fair hearing, and Justice Greene’s recognition of the importance of Scarcella’s misconduct,” said Shakur’s attorney Ron Kuby.

“We have no doubt that we will prevail at a new trial, should the Kings County District Attorney be so foolish as to try to perpetuate this injustice further.”

“We are reviewing the decision and considering our options,” said a spokeswoman for the Brooklyn DA’s office.

In hearing last year on whether to grant Shakur a new trial, prosecutors argued they would’ve gotten a conviction even without Scarcella’s testimony, saying there was no indication it was “fabricated.”

Scarcella’s lawyer called the judge’s decision “mistaken.”

“[Scarcella] took a statement in this case, not a confession, violated no police procedures and did nothing wrong,” said Scarcella’s lawyers Alan M. Abramson and Joel Cohen.
