A more thorough explanation:

N.Y.S.

N.Y.S. stands for New York Supplement. It is a publication that contains court cases from the state of New York that were not included in the official reports.

For example, if a court case was heard in New York and was not included in the official reports, it may be published in the N.Y.S. instead. This allows lawyers and judges to access a wider range of legal precedents when making decisions.

Another example would be if a lawyer is researching a case and finds a relevant decision in the N.Y.S., they can use that case to support their argument in court.

These examples illustrate how the N.Y.S. is a valuable resource for legal professionals in New York, as it provides access to a wider range of legal precedents and decisions.
