HRS §124B-72
What happens if a civilian ignores a military court subpoena
This section says that if a person who is not in the military gets a valid subpoena from a military court, is paid witness fees, and then willfully refuses to show up, testify, or provide evidence, they commit a state offense. The military court can punish them like a civil court would.
