When you are at an inquiry, the coroner can choose what evidence to accept. The coroner can accept evidence even if it would not be allowed in a court of law. You need to know that the coroner must think the evidence is necessary or desirable for the inquiry's purposes, as stated in section 57. If a witness gives evidence for the inquiry, but not at an inquest, it must be written down. The witness must check the written evidence and sign it. This is what happens if the coroner accepts the evidence. The coroner has to follow certain rules when deciding what evidence to accept. These rules help the coroner make fair decisions about what evidence is important for the inquiry. You can find more information about these rules in other parts of the law.
