Rhode Island General Laws Title 12. Criminal Procedure § 12-16.1-3. Court order

If at the hearing the judge determines: (1) that the witness may be material and necessary, (2) that his or her attending and testifying are not adverse to the interests of this state or to the health or legal rights of the witness, (3) that the laws of the state in which he or she is requested to testify will give him or her protection from arrest and the service of civil and criminal process because of any act committed prior to his arrival in the state under the order, and (4) that as a practical matter the possibility is negligible that the witness may be subject to arrest or to the service of civil or criminal process in any state through which he or she will be required to pass, the judge shall issue an order with a copy of the certificate attached, directing the witness to attend and testify, directing the person having custody of the witness to produce him or her, in the court in which the criminal action is pending or where the grand jury investigation is pending, at a time and place specified in the order, and prescribing any conditions that the judge shall determine.
