Scope and Content Note

The series consists of microfilm copies of the case files of the First District Public Service Commission (1907-1921), with jurisdiction in New York City, and case files. Also included is so-called "supplemental case file material" (those materials not filmed because of size or condition, including maps, drawings and/or exhibits; or materials filmed but for which the film was found to be of poor quality). Case files typically include petitions, briefs, orders, correspondence, exhibits and testimony.

Both the First District case files and the Minutes of the Transit Commission (Series 19595) are arranged by the same numerical scheme, and occasionally records from both bodies are contained on the same microfilm reel. As a result the records are difficult to access. The "supplemental material" contains both minutes and case file records.
