State v. Michelle R. Popenhagen, 2008 WI 54, reversing 2007 WI App 16
For Popenhagen: James B. Connell
Issue: Whether statements made when confronted with documents produced in violation of § 968.135 subpoena procedure are suppressible.
Holding:
¶81 The defendant’s motion to suppress the incriminating statements in the present case is substantially similar in nature to a motion to quash the subpoena. Both motions prevent the State’s using evidence derived from the subpoena. The documents are derived from the unlawful subpoena and the incriminating statements are derived from the documents derived from the unlawful subpoena.
…
¶87 When the legislature allows a motion to quash or limit a subpoena to prevent the State from enforcing a subpoena issued in violation of Wis. Stat. § 968.135, it is absurd and unreasonable to allow the State to use incriminating statements derived directly from such a subpoena and to gain an advantage by violating the statute. The legislature could not have intended that the statute would be interpreted in such a way to allow circumvention of the carefully drafted legislative requirements and safeguards for the issuance of a subpoena under Wis. Stat. § 968.135. [42]
