A Bronx court has dismissed a driving while intoxicated (DWI) charge against C. Palacios, ruling that the evidence presented was insufficient to support the accusation. The decision, made on April 9, 2026, affects how similar cases may be prosecuted in the future, particularly regarding the use of retrograde extrapolation to establish blood alcohol content (BAC) levels.

The ruling comes after Palacios was charged with multiple DWI offenses following an incident where he allegedly rear-ended another vehicle. The case has drawn attention due to the legal implications surrounding the evidence used to charge him and the standards for proving intoxication.

Background

C. Palacios was arrested on September 21, 2025, after reportedly causing a car accident at approximately 4:05 a.m. An officer noted signs of possible intoxication, including bloodshot eyes and slurred speech. However, Palacios did not exhibit the smell of alcohol on his breath and stated he had consumed only one beer.

Following his arrest, a breath test was conducted about eight hours later, revealing a BAC of .045, which is below the legal limit of .08 for intoxication. Despite this, the prosecution charged Palacios with driving while intoxicated, driving while intoxicated per se, and driving while ability impaired, relying on a theory called retrograde extrapolation to argue that his BAC was above the legal limit at the time of the accident.

The Ruling

Judge David L. Goodwin of the Criminal Court of the City of New York ruled that the charge of driving while intoxicated per se was facially insufficient. The court stated, "The People concede that the § 1192(2) count is facially insufficient because no valid chemical test shows a BAC at or above .08." This ruling was based on the lack of a valid chemical test conducted within the required timeframe and the fact that retrograde extrapolation is not recognized as a valid chemical test under New York law.

The judge noted that while the other charges against Palacios could proceed, the per se DWI charge was dismissed due to the absence of a chemical test result that met the legal requirements. The ruling emphasized that retrograde extrapolation, which estimates a person's BAC at an earlier time based on later test results, cannot substitute for a valid chemical test required by law.

Impact

This ruling has significant implications for future DWI cases in New York. It clarifies that prosecutors must rely on valid chemical test results conducted within a specific timeframe to support per se DWI charges. The court's decision reinforces the importance of adhering to established legal standards when presenting evidence in intoxication cases.

The ruling may also influence how law enforcement and prosecutors handle DWI cases moving forward, particularly in situations where there is a delay in administering breath tests. The court's dismissal of the per se charge highlights the challenges that prosecutors face when relying on retroactive methods to establish intoxication.

What's Next

While the per se DWI charge against Palacios has been dismissed, the remaining charges of driving while intoxicated and driving while ability impaired will proceed. The prosecution may still appeal the ruling regarding the dismissed charge, but details on any potential appeal were not available in the court filing. The outcome of this case may set a precedent for how similar cases are handled in the future.
