Manhattan District Attorney Cyrus R. Vance Jr. issued guidelines to prosecutors Friday intended to promote uniformity and transparency in the filing of criminal charges against businesses and other organizations.

Daniel R. Alonso, Mr. Vance’s top deputy and author of the guidelines, said that as far as he knows the policy is the first of its kind to be issued by a state prosecutor’s office. They are modeled after guidelines promulgated by the U.S. Justice Department.
