Failure to file, record or send shall not invalidate the annexation and the duty to file, record or send shall be a continuing one. The ordinance that is filed, recorded or sent shall describe the annexed territory and the associated population. The information filed with the Secretary of State shall be utilized in making recommen- dations for adjustments to entitlements under the federal revenue sharing program and distribution of funds under Ch. 79, Wis.

      (1)   Time of Commencement. An action on any grounds whatsoever, whether denominated procedural or jurisdictional, to contest the validity of an annexation shall be commenced within the time after adoption of the annexation ordinance provided by Section 893.73(2), Wis. Stats.
      (2)   Preference in Circuit Court. An action contesting an annexation shall be given preference in circuit court.
   (k)   Review of Annexations.
      (1)   Annexations Within Populous Counties. No annexation proceeding within a county having a population of fifty thousand (50,000) or more shall be valid unless the person causing a notice of annexation is published under Subsection (c) shall within five (5) days of the publication mail a copy of the notice, legal description and a scale map of the proposed annexation to the clerk of each municipality affected and the Wisconsin Department of Administration (Department). The Department may within twenty (20) days after the receipt of the notice mail to the clerk of the town within which the territory lies and to the clerk of the proposed annexing village or city a notice that in its opinion the annexation is against the public interest. No later than ten (10) days after mailing the notice, the Department shall advise the clerk of the town in which the territory is located and the clerk of the village or city to which the annexation is proposed of the reasons the annexation is against the public interest as defined in Subsection (k)(2) below. The annexing municipality shall review the advice before final action is taken.
      (2)   Definition of Public Interest. For purposes of this Subsection, "public interest" is determined by the Wisconsin Department of Administration after consideration of the following:
         a.   Whether the government services, including zoning, to be supplied to the territory could clearly be better supplied by the town or some other village or city whose boundaries are contiguous to the territory proposed for annexation which files with the circuit court a certified copy of a resolution adopted by a two-thirds vote of the elected members of the governing body indicating a willingness to annex the territory upon receiving an otherwise valid petition for the annexation of the territory.
         b.   The shape of the proposed annexation and the homogeneity of the territory with the annexing village or city and any other contiguous village or city.
      (1)   Unanimous Approval Annexations. If a petition for direct annexation signed by all of the electors residing in the territory and the owner of all of the real property in the territory is filed with the city or village clerk, and with the town clerk of the town or towns in which the territory is located, together with a scale map and a legal description of the property to be annexed, an annexation ordinance for the annexation of the territory may be enacted by a two-thirds vote of the elected members of the governing body of the city or village without compliance with the notice requirements of Subsection (c) above. In such annexations, subject to Subsection (k), the person filing the copy of the scale map and a legal description of the territory to be annexed to the Wisconsin Department of Administration and the governing body shall review the advice of the Department, if any, before enacting the annexation ordinance.
   (m)   Review Requirements. The provisions of Subsection (I) do not eliminate the necessity for review as required by Subsection (k).
   (n)   Annexation of Town Islands. Upon its own motion, a city or village by a two-thirds vote of the entire membership of its governing body may enact an ordinance annexing territory which comprises a portion of a town or towns and which was completely surrounded by territory of the village or city on December 2, 1973. The ordinance shall include all surrounded town areas except those exempt by mutual agreement of all of the governing bodies involved. The annexation ordinance shall contain a legal description of the territory and the name of the town or towns from which the territory is detached. Upon enactment of the ordinance, the city or village clerk immediately shall file six (6) certified copies of the ordinance in the office of the Wisconsin Secretary of State, together with six (6) copies of the scale map. The Secretary of State shall forward two (2) copies of the ordinance and scale map to the Wisconsin Department of Transportation, one (1) copy to the Wisconsin Department of Natural Resources, one (1) copy to the Wisconsin Department of Revenue, and one (1) copy to the Wisconsin Department of Administration. This subsection does not apply if the town island was created only by the annexation of a railroad right-of-way or drainage ditch. This Subsection does not apply to land owned by a town government which has existing town government buildings located thereon. No town island may be annexed under this Subsection if the island consists of over sixty-five (65) acres or contains over one hundred (100) residents. After December 2, 1973, no city or village may, by annexation, create a town island, which is completely surrounded by the city or village.
   (o)   Effective Date of Annexations. Because the creation of congressional, legislative, supervisory and aldermanic districts of equal population is a matter of statewide concern, any annexation action that affects a tract of land that is the subject of an ordinance enacted or resolution adopted by any city during the period from January I, 1990 to April I, 1991, or any later date, expressing an intent to not exercise the city's authority to annex territory before April 1, 1991, or the specified later date, taken by a municipality during the period beginning on April 1 of the year commencing after each federal decennial census of population and ending on June 30 of the year commencing after that census, is effective on July 1 of the year commencing after that census or at such later date as may be specified in the annexation ordinance. This Subsection first applies to annexations effective after March 31, 1991.
   (p)   Annexation of Municipal-Owned Territory. In addition to other methods provided by law and subject to Sections 59.692(7), 66.0223 and 66.0307, Wis. Stats., territory owned by and lying near but not necessarily contiguous to a village or city may be annexed to a village or city by ordinance enacted by the board of trustees of the village or the common council of the city, provided that in the case of noncontiguous territory the use of the territory by the village or city is not contrary to any town or county zoning regulation. The ordinance shall contain the exact description of the territory annexed and the names of the towns from which detached and shall operate to attach the territory to the village or city upon the filing of six (6) copies of a plat showing the boundaries of the territory attached. Two (2) copies of the ordinance and plat shall be forwarded by the Wisconsin Secretary of State to the Wisconsin Department of Transportation, one (I) copy to the Wisconsin Department of Natural Resources, one (1) copy to Wisconsin Department of Revenue, and one (1) copy to the Wisconsin Department of Public Instruction.
