The parties shall mutually agree on the methods of stratification, computation of ratio and selection of the parcels to be appraised, the number of such parcels and the number of witnesses to be heard with respect to such issue. Such parcels shall be selected so as to constitute a stratified random sample of all locally assessed taxable parcels on the assessment roll containing the assessment under review or the latest assessment roll sampled by the board in establishing the state equalization rate for such roll; provided, however, for assessments on rolls completed after December thirty-first, nineteen hundred eighty-one, in special assessing units such parcels shall constitute a stratified random sample of all locally assessed taxable property in the major type of property in which the property under review is classified; provided further, however, for assessment rolls completed after December thirty-first, nineteen hundred eighty-one, in special assessing units public utility property shall be sampled as the parties agree, or if the parties fail to agree, as the court directs. In special assessing units for assessment rolls completed prior to January first, nineteen hundred eighty-two and in other than special assessing units public utility property shall be added to the parcels selected for the stratified random sample when such property is a significant portion of the total locally assessed taxable assessed value of the assessing unit; in such case, representative parcels shall be agreed upon by the parties or selected by the court if no such agreement is reached. In the event that proceedings for more than one year are consolidated for trial, evidence may be introduced to adjust the ratio derived from the selected parcels provided for in this subdivision so as to make such ratio applicable to the other assessment rolls included in such consolidation. For the purpose of this subdivision, stratification shall be based on major type of property and assessed value within each such major type; provided however, that for assessments on rolls completed after December thirty-first, nineteen hundred eighty-one, in special assessing units stratification shall be based on the assessed value of parcels within the major type of property in which the assessment under review is classified. Nothing in this subdivision shall prevent the parties from agreeing, with approval of the court, to any other method of stratification in place of or in addition to major type of property or assessed value of property. Stratification shall be made in accordance with the information contained on the assessment roll from which the parcels to be appraised are to be selected. The assessment under review shall be excluded from the stratification and the sample.
In addition to the selected parcels, additional parcels shall be selected in the same manner for use as substitutes for selected parcels for which the parties agree that an appraisal cannot be made. If the parties fail to agree on the feasibility of appraising a selected parcel or an appropriate substitute the court shall make such determinations.
In the event the parties fail to agree on such methods or selected parcels or on the number of witnesses, upon application of either party the court or referee shall select a qualified expert, who shall devise such methods and select the parcels to be appraised, or shall determine the number or witnesses, or both, as the case may be. Before any testimony is given by either party as to the value of such parcels, each party shall simultaneously file with the court or referee, on a date fixed by the court or referee, a written statement or tabulation of the appraised values placed upon such parcels by the witnesses of the respective parties, and each party shall serve on the other at the same time a copy of such statement or tabulation of values stated by his witnesses.
The parties shall be limited in their proof on the trial of such issue to such parcels and witnesses, except that in any event, whether or not parcels are selected as hereinabove provided, evidence may be given by either party as to the following:
