Also, I believe your WI statute reference is incorrect, there isn't an 806.7.
However, there is an 806.07 which I think is the one that you were intending to reference. It says:
"806.07 Relief from judgment or order.
(1) On motion and upon such terms as are just, the court, subject to subs. (2) and (3), may relieve a party or legal representative from a judgment, order or stipulation for the following reasons:
(a) Mistake, inadvertence, surprise, or excusable neglect;
(b) Newly-discovered evidence which entitles a party to a new trial under s. 805.15 (3);
(c) Fraud, misrepresentation, or other misconduct of an adverse party;
(d) The judgment is void;
(e) The judgment has been satisfied, released or discharged;
(f) A prior judgment upon which the judgment is based has been reversed or otherwise vacated;
(g) It is no longer equitable that the judgment should have prospective application; or
(h) Any other reasons justifying relief from the operation of the judgment.
(2) The motion shall be made within a reasonable time, and, if based on sub. (1) (a) or (c), not more than one year after the judgment was entered or the order or stipulation was made. A motion based on sub. (1) (b) shall be made within the time provided in s. 805.16. A motion under this section does not affect the finality of a judgment or suspend its operation. This section does not limit the power of a court to entertain an independent action to relieve a party from judgment, order, or proceeding, or to set aside a judgment for fraud on the court."
If that is the statute you were referencing, then you would have to make a motion for the court to reconsider, include your basis for the reconsideration (FACTUAL, not 'how abouts'), and ask that the court reverse its prior ruling.
