Reporting
New York called the price of its own rulebook a trade secret. We did the math anyway.
Most legal research tools cite the law. We went after the record behind it: records requests, appeals, and every document published.
What we derived from the public record
$4,808.32
The State published its discounted rate and blacked out the private one. $2,884.99 divided by 0.6.
What New York disclosed on appeal
$4,808.31
On July 22, 2026 the Department of State called its own redactions incorrect and released every rate.
