23N   Right to interpreter  

Where an investigating official believes on reasonable grounds that a person who is under arrest or a protected suspect is unable, because of inadequate knowledge of the English language or a physical disability, to communicate orally with reasonable fluency in that language, the official must, before starting to question the person, arrange for the presence of an interpreter and defer the questioning or investigation until the interpreter is present.
