Any individual called to testify before a special inquiry judge, whether as a witness or principal, if not represented by an attorney appearing with the witness before the special inquiry judge, must be told of his privilege against self-incrimination. Such an individual must be informed that he has the right to have an attorney present to advise him as to his rights, obligations and duties before the special inquiry judge. Such attorney may be present as an observer and advisor during all proceedings, unless immunity has been granted pursuant to sections 19-1114, 19-1115 or 19-1122, Idaho Code. After immunity has been granted, such an individual may leave the special inquiry room to confer with his attorney.
