190.45 - Grand jury; waiver of immunity.

§ 190.45  Grand jury; waiver of immunity.    1.    A  waiver  of  immunity  is a written instrument subscribed by a  person who is  or  is  about  to  become  a  witness  in  a  grand  jury  proceeding,   stipulating   that   he   waives   his  privilege  against  self-incrimination and any possible or prospective immunity to which  he  would otherwise become entitled, pursuant to section 190.40, as a result  of giving evidence in such proceeding.    2.  A waiver of immunity is not effective unless and until it is sworn  to  before  the  grand  jury  conducting  the  proceeding  in  which the  subscriber has been called as a witness.    3.  A person who is called by the people as a witness in a grand  jury  proceeding and requested by the district attorney to subscribe and swear  to  a  waiver  of  immunity before giving evidence has a right to confer  with counsel before deciding whether he will comply with  such  request,  and, if he desires to avail himself of such right, he must be accorded a  reasonable  time  in  which  to  obtain and confer with counsel for such  purpose.  The district attorney must inform  the  witness  of  all  such  rights before obtaining his execution of such a waiver of immunity.  Any  waiver  obtained,  subscribed or sworn to in violation of the provisions  of this subdivision is invalid and ineffective.    4.  If a grand jury witness subscribes  and  swears  to  a  waiver  of  immunity  upon  a  written agreement with the district attorney that the  interrogation will be limited to certain specified subjects, matters  or  areas  of  conduct, and if after the commencement of his testimony he is  interrogated and testifies concerning another subject, matter or area of  conduct not included in such written  agreement,  he  receives  immunity  with  respect to any further testimony which he may give concerning such  other subject, matter or area of conduct and the waiver of  immunity  is  to that extent ineffective.
