WHEREAS at an ordinary meeting, held on the 8th day of March 1977, the Masterton County Council (in this Act referred to as the Council) passed a special order pursuant to section 87 of the Counties Act 1956 declaring that section 107 of that Act shall cease to apply to the Masterton County and adopting a system of differential rating: And whereas that special order was invalid by virtue of the fact that the second public notice of the date, time, and place fixed for the meeting at which it was to be confirmed was not given within the time prescribed by section 87 of that Act: And whereas that special order was further invalid by virtue of the fact that a plan of the said county showing the boundaries of the proposed differential rating areas was not deposited in the office of the Council as prescribed by section 111B(3) of that Act: And whereas that special order was further invalid by virtue of the fact that a statement specifying the matters taken into account as the basis for the pro-posed division of the said county and the general effect that the division is expected to have on the incidence of general rates as between the several proposed differential rating areas was not deposited in the office of the Council as prescribed by section 111B(3) of that Act: And whereas that special order was further invalid by virtue of the fact that public notice of the times when and the place where inspection of the plan and statement may be made was not given and the plan and statement was not made open for inspection by the public as prescribed by section 111B(4) of that Act: And whereas that special order was further invalid by virtue of the fact that it did not describe the differential rating areas as prescribed by section 111B(1)(a) of that Act: And whereas in reliance on that special order the Council has made and levied certain rates throughout the County for each of the 3 rating years beginning on the 1st day of April 1977: And whereas it is desirable that the said special order and the said rates be validated:
