However, as far as undeveloped properties are concerned, until the first six-yearly review, account will be taken of changes in rental values since 1st January 1961.
II. – The coefficients referred to in I are set, for undeveloped properties, by departmental agricultural or forestry region and by group or sub-group of type of crop or property and, for developed properties, by geographical sector and by type or category of property.

The coefficients are notified to the mayors of the municipalities concerned and to the presidents of the public establishments for inter-municipal cooperation for their own tax purposes. After application of the posting procedure under the conditions provided for in article 1510 they may, within thirty days, be the subject of an administrative appeal by the mayor or the taxpayers’ representatives sitting on the advisory commission. This appeal is made to the commission set up by Article 1651, which shall take a final decision.
