The head of the District Attorneys Association of New York slammed Gov. Andrew Cuomo and the Legislature for leaving prosecutors in the lurch — saying they approved an overhaul of criminal justice laws without providing adequate funding.

Albany approved new laws this year that end cash bail for 90% of low-level crimes, reduce the length of time before cases are brought to trial and bar prosecutors from withholding evidence until the day a trial begins.

“There is no money in the New York State budget for criminal justice reform. The process by which they brought about their ‘reform’ was reckless and irresponsible and now this idea that the state is providing the county with resources is just insulting,” seethed David Soares, president of the NYS District Attorneys Association and the Albany County DA.

“What is remarkable is our lawmakers passed what they considered to be historic criminal justice reforms without speaking to anyone besides the activists. No chiefs of police, or the DA’s association, or the Sheriff’s Association,” the Democrat groused.

He estimated the district attorneys office would need a 50% budget increase to account for extra staff, updated software, expedited transcripts, body camera storage, etc.

Manhattan DA Cyrus Vance’s office estimates the changes require “millions.”

“Lawmakers did not provide any funding for the new mandates. This was a missed opportunity to transform New York’s criminal justice system into a national model. Without adequate funding, the patchwork of reforms simply will not be as successful as they intended to be,” Vance said in testimony before the City Council in May on the funding issue.

The nonprofit Vera Institute of Justice estimates pretrial services will cost the state an annual $75 million. New Jersey spent $62 million on 33,741 cases last year.

Cuomo’s budget office insisted there’s adequate funds in the budget for DA’s offices and said prosecutors would derive savings by diverting many defendants from jail pending trial.

“The FY 2020 Enacted Budget includes groundbreaking legislation going into effect next year that dramatically reforms New York’s bail system, ensuring that approximately 90% of cases where people are charged, but not yet convicted, will remain out [of] jail before their day in court,” state Division of Budget spokesman Freeman Klopott said.

“This will provide savings for local governments, which have always supported pretrial services, as the Enacted Budget delivers more than $200 million to county governments through new revenue sources.”

He added, New York State is spending $7 billion on criminal justice this year, and the resources for the implementation of these critical reforms will be available.

Yet Soares blasted the figures as misleading, saying county governments can spend their share of the funds in any way they please — such as diverting the funds to roads or bridges ahead of law enforcement needs.

The state Senate and Assembly declined comment.
