HRS §281-21
Subpoenas and witness fees for liquor hearings
This section says who can deliver subpoenas for liquor hearings and who pays witnesses. Police officers, investigators, or other law enforcement can serve them. Witnesses get fees as set by another law, paid by the liquor commission/board or by the party who asked for the subpoena.
