HRS §480-23
Immunity from prosecution
This section covers what happens when someone refuses to testify or produce evidence in an antitrust investigation because it might incriminate them. If a court orders them to do so, they must comply, and in exchange, they cannot be criminally charged for what they reveal. Lying or disobeying the order is still a crime.
