Law clerks in NY Supreme Court (for non-New Yorkers, that's the major trial court, not an appellate court) are lawyers characterized by their excellent credentials.
Unlike in federal court where clerks get their jobs right out of school and serve a few years, the NY law clerks serve as long as the judge, or longer if a successor judge is pleased with the work.
Usually attorneys trying to contact a judge contact the law clerk first.
