Under the Hawai’i Rules of Penal Procedure and the Constitution you have the right to have your case heard in a timely fashion. Hawai’i penal procedure Rule 48 says that you have to be brought to trial within 180 days of your arrest or charging. Certain periods of time can be excluded, giving the government more time.
The Constitutional requirements don’t have a specific time requirement but look at a variety of factors like the cause of the delay and the prejudice the defendant has suffered in deciding if there is a speedy trial violation.
