What is the test for a defendant to be found guilty of a series of criminal charges under New York State Public Prosecutions for failing to comply with the requirements of the Criminal Prosecution Service?

This action commenced on April 5, 2015, when the People served and filed a criminal court complaint charging the defendant with the afore-mentioned offenses and another offense the count of which was later withdrawn. The accusatory instrument gave the People a readiness deadline of 90 days (CPL 30.30[1][b] ). The defendant bears the burden of going forward with sworn allegations of fact to show that there has been an inexcusable delay beyond the time allowed by the statute, and then the People have the burden of justifying that delay (see People v. Santos, 68 N.Y.2d 859 [1986] ).
