Kenneth Rigby


Kenneth Rigby – NY State Bar #2345189



Who: Law professors filed a grievance regarding Kenneth Rigby’s serious misconduct while prosecuting Sami Leka on behalf of the Kings County District Attorney’s Office (KCDAO). Despite Rigby’s misconduct, at the time of the complaint, Rigby had no record of public discipline in the New York Attorney Detail Report.

What they did: In People v. Leka, the United States Court of Appeals determined that Rigby committed a Brady violation. The court reversed Leka’s conviction for murder.

The court found that a police officer named Garcia was a witness to the crime whose testimony made it very unlikely that Leka had shot the victim and the testimony would have had a “seismic impact” on the trial. Prosecutor Rigby had told Leka’s attorney two years before trial that an officer witness would identify Leka as the shooter. Then, only three business days before trial and two years after first disclosing that he had an officer witness, Rigby finally disclosed the officer’s name. That same day, Rigby finally disclosed that the officer would actually not identify Leka. Rigby asked the court for an order barring the defense from speaking to the officer, which the court granted. But Rigby never called Garcia to testify.

In finding this to be a Brady violation, the Court reasoned there was “no doubt that the prosecutor had that information from the beginning of the case: Garcia was a police officer who witnessed a murder. And it [was] clear that the information was favorable to the defense. So there is really no question but that the government suppressed information that it was required to turn over.” The court found that Rigby “actively suppressed” the information for years leading to trial. The Court of Appeals noted, “[I]t is ridiculous to think that the prosecution did not know what a police officer saw as a witness to a shooting; yet the last-minute disclosure consisted of nothing but Garcia’s name and perhaps his address.”

The late disclosure left the defense in an investigative and tactical disadvantage too close to trial, rendering the late disclosure insufficient. As the Court of Appeals explained, “The opportunity for use under Brady is the opportunity for a responsible lawyer to use the information with some degree of calculation and forethought. A responsible lawyer could not put Garcia on the stand without essential groundwork. And a responsible lawyer in the midst of the pressures and paranoias of trial may well deploy scarce trial resources doing other things… the options left open to the defense were to expend and perhaps waste scarce trial resources on a possible dry hole, or to call a witness cold, which would be suicidal. These are not opportunities for use. It is not enough for the prosecution to avoid active suppression of favorable evidence; Brady and its progeny require disclosure.”

The court reversed the conviction and Leka was finally freed after 11.5 years in prison. 

Why it’s wrong: One of the most damaging forms of prosecutorial misconduct is the Brady violation—when law enforcement suppresses exculpatory or impeachment evidence. When provided in a timely and transparent fashion, Brady disclosures can permit the defense to investigate and litigate different leads, present evidence that the prosecution’s case is inaccurate, present evidence that the testimony of the prosecution’s witnesses is inaccurate or false, present evidence of the accused’s innocence to the jury, and ultimately, protect the accused from a wrongful conviction. It is unsurprising, then, that the National Registry of Exonerations found that suppression of Brady evidence played a role in over 44 percent of known wrongful convictions and 61 percent of known wrongful convictions for murder.

Prosecutors wield immense power, the power to seek punishment on behalf of the state, and should be held to the highest ethical standards.  The grievance identifies the following then-applicable ethical rules that Rigby’s conduct may implicate:

  • Rule DR 7-103(b) (from the Code of Professional Responsibility, later replaced by the Rules of Professional Conduct)  required a prosecutor to make timely disclosure of the existence of evidence known to the prosecutor that tends to negate the guilt of the accused, mitigate the degree of the offense or reduce the punishment.
  • Rules DR 7-102(a)(3) and DR 7-109(a) similarly required disclosure, and prohibited knowing concealment, of evidence.
  • Rule DR 7-102 stated attorneys were not to knowingly make a false statement to the court or use evidence they knew to be false.
  • Rule DR 1-102 prohibited attorneys from engaging in conduct involving dishonesty, fraud, deceit or misrepresentation.
  • Rule DR 1-102 prohibited attorneys from engaging in conduct that was prejudicial to the administration of justice, or engaging in any other conduct that adversely reflected on their fitness to practice law.

What can be done about it: The grievance calls for the committee to investigate and issue public discipline, including disbarment (revoking Rigby’s law license). It also calls for a broader investigation into other cases prosecuted by the same prosecutor, and to determine whether the KCDAO supervising and managing attorneys complied with their duties under Rule 5.1 of Professional Conduct.
