807.15.Penalty for certain actions by prisoners.

Section 807.15 addresses actions and special proceedings, including a petition for a common law writ of certiorari, brought by a prisoner, as defined in Section 801.02 (7)(a)2. under subsection (1). Subsection (2) lets the court, on its own motion or on any party’s motion, order the department of corrections to extend the prisoner’s mandatory release date calculated under Section 302.11 (1) or the prisoner’s eligibility for release to extended supervision under Section 302.113 (3)(bm) or 302.114 (3)(c), or order the sheriff to deprive the prisoner of good time under Section 302.43, if the court finds that the action or proceeding was filed for a malicious purpose, was filed solely to harass the party against which it was filed, or that the prisoner testified falsely or otherwise knowingly offered false evidence or provided false information to the court.

Subsection (3) puts limits on that penalty. Any order extending a release date or eligibility date, or depriving good time, must specify the number of days involved. An order extending a mandatory release date or depriving good time may not require the prisoner to serve more days than the prisoner’s sentence provides. And an order affecting extended-supervision eligibility for a prisoner subject to Section 302.113 may not require the prisoner to serve more days in prison than the total length of the bifurcated sentence. Subsection (4) limits the section as a whole to prisoners who committed their offense on or after September 1, 1998.
