Senate approves limits on defense subpoenas after contested floor debate

The Iowa Senate approved Senate File 571, which places limits on the use of defense subpoenas in criminal discovery by requiring defendants to apply to the court and to prove by a preponderance of evidence that requested materials are material, necessary, exculpatory and admissible and that there is a compelling need that cannot be satisfied by other sources.

Sponsor Senator Taylor said the bill would require judicial oversight for defense subpoenas and include provisions to appoint counsel for an indigent person or entity served with a subpoena. Opponents warned the measure could make it harder for defendants to obtain evidence needed to mount an effective defense. One floor speaker said, “The bill in front of us would make it harder for innocent people to earn their freedom,” arguing the existing rules already provide high standards and court oversight.

Proponents, citing victim privacy concerns and a chilling effect on victims and witnesses, said the bill strikes a balance between defendant rights and protection for third parties. After debate, the Senate read the bill for the final time and the chamber recorded a roll call of 34 ayes and 15 nays; the bill was declared to have passed by a constitutional majority.

The bill’s text tightens procedures for defense subpoenas and clarifies that private information of crime victims and unrelated third parties should not be subject to routine defense fishing expeditions without court review.
