Jurisdiction context
Not a civil service jurisdiction
This department is not among the NJCSC Appendix A jurisdictions, so major discipline here follows a different statutory track (generally N.J.S.A. 40A:14), with appeals that usually go to the Superior Court rather than the Civil Service Commission.
See the context on non-civil-service departments.
