A. Authorized; Conditions: Witnesses in any proceeding in the court, other than the police officers or peace officers, shall be entitled to a sum per each day of attendance, plus mileage for each mile actually and necessarily traveled in going to and returning from the place of attendance. However, no witness shall receive fees or mileage in more than one case for the same period of time or the same travel. A defendant seeking to subpoena witnesses must deposit with the court clerk a sum sufficient to cover fees and mileage for one day of attendance for each witness to be summoned, and such deposit shall be returned to the defendant if the defendant is found not guilty, but such deposit shall not be required from an indigent defendant who files an affidavit setting out:
1. The names of no more than three (3) witnesses;
2. That the defendant, by reason of his poverty, is unable to provide the fees and mileage allowed by law;
3. That the testimony of the witnesses is material; and
4. That their attendance at the trial is necessary for his proper defense.
B. Paid By City: The fees of such witnesses shall be paid by the city. (See appendix A of this code.) (1988 Code § 6-130)
