Limit Of House-tax Increase By Civic Authorities

Is the limit of increase in Property Tax under revision of sub-rule (3) of the Taxation Rules in Chapter VIII of Schedule D of the Maharashtra Municipal Corporation Act 40% of the amount of the Property Tax payable in the year immediately preceding the year or such revision. If so, what can a grieving member of public do after receiving the Notice for 100% increase in Property Tax and the Civic body failing to respond in over a year and no response to the complaint lodged to the District Collector in over a month?
