(1)    Except as otherwise specifically provided by law, any person aggrieved by a decision specified in s. 227.52 shall be entitled to judicial review of the decision as provided in this chapter and subject to all of the following procedural requirements:

      (a)   

         1.    Proceedings for review shall be instituted by serving a petition therefor personally or by certified mail upon the agency or one of its officials, and filing the petition in the office of the clerk of circuit court for the county where the judicial review proceedings are to be held. If the agency whose decision is sought to be reviewed is the tax appeals commission, the banking institutions review board, or the credit union review board, the petition shall be served upon both the agency whose decision is sought to be reviewed and the corresponding named respondent, as specified under par. (b) 1. to 4.

         2.    Unless a rehearing is requested under s. 227.49, petitions for review of contested cases shall be served and filed within 30 days after the service of the decision of the agency upon all parties under s. 227.48. If a rehearing is requested under s. 227.49, any party desiring judicial review under this subdivision shall serve and file a petition for review within 30 days after service of the order finally disposing of the application for rehearing, or within 30 days after the final disposition by operation of law of any such application for rehearing. The 30-day period for serving and filing a petition under this subdivision commences on the day after personal service or mailing of the decision by the agency.

         2m.    Petitions for review of cases other than contested cases shall be served and filed within 30 days after personal service or mailing of the decision by the agency.

         3.    If the petitioner is a resident, the proceedings shall be held in the circuit court for the county where the petitioner resides, except that if the petitioner is an agency, the proceedings shall be in the circuit court for the county where the respondent resides and except as provided in ss. 73.0301 (2) (b) 2., 77.59 (6) (b), 108.227 (6), 182.70 (6), and 182.71 (5) (g). If the petitioner is a nonresident, the proceedings shall be held in the county where the property affected by the decision is located or, if no property is affected, in the county where the dispute arose. If all parties stipulate and the court to which the parties desire to transfer the proceedings agrees, the proceedings may be held in the county designated by the parties. If 2 or more petitions for review of the same decision are filed in different counties, the circuit judge for the county in which a petition for review of the decision was first filed shall determine the venue for judicial review of the decision, and shall order transfer or consolidation where appropriate.

      (b)    The petition shall state the nature of the petitioner’s interest, the facts showing that petitioner is a person aggrieved by the decision, and the grounds specified in s. 227.57 upon which petitioner contends that the decision should be reversed or modified. The petition may be amended, by leave of court, though the time for serving the same has expired. The petition shall be entitled in the name of the person serving it as petitioner and the name of the agency whose decision is sought to be reviewed as respondent, except that in petitions for review of decisions of the following agencies, the latter agency specified shall be the named respondent:

         1.    The tax appeals commission, the department of revenue.

         3.    The credit union review board, the office of credit unions.

         4.    The banking institutions review board, the division of banking, except if the petitioner is the division of banking, the prevailing parties before the banking institutions review board shall be the named respondents.

      (c)    A copy of the petition shall be served personally or by certified mail or, when service is timely admitted in writing, by first class mail, not later than 30 days after the institution of the proceeding, upon each party who appeared before the agency in the proceeding in which the decision sought to be reviewed was made or upon the party’s attorney of record. A court may not dismiss the proceeding for review solely because of a failure to serve a copy of the petition upon a party or the party’s attorney of record unless the petitioner fails to serve a person listed as a party for purposes of review in the agency’s decision under s. 227.47 or the person’s attorney of record.

      (d)    Except in the case of the tax appeals commission, the banking institutions review board, and the credit union review board, the agency and all parties to the proceeding before it shall have the right to participate in the proceedings for review. The court may permit other interested persons to intervene. Any person petitioning the court to intervene shall serve a copy of the petition on each party who appeared before the agency and any additional parties to the judicial review at least 5 days prior to the date set for hearing on the petition.

   (2)   Every person served with the petition for review as provided in this section and who desires to participate in the proceedings for review thereby instituted shall serve upon the petitioner, within 20 days after service of the petition upon such person, a notice of appearance clearly stating the person’s position with reference to each material allegation in the petition and to the affirmance, vacation or modification of the order or decision under review. Such notice, other than by the named respondent, shall also be served on the named respondent and the attorney general, and shall be filed, together with proof of required service thereof, with the clerk of the reviewing court within 10 days after such service. Service of all subsequent papers or notices in such proceeding need be made only upon the petitioner and such other persons as have served and filed the notice as provided in this subsection or have been permitted to intervene in said proceeding, as parties thereto, by order of the reviewing court.
