Commonwealth Consolidated Acts

INTERSTATE ROAD TRANSPORT ACT 1985 - SECT 4A

             (1)  In this section:

"index number" , in relation to a quarter, means the All Groups Consumer Price Index number, being the weighted average of the 8 capital cities, published by the Australian Statistician in respect of that quarter.

"relevant amount" means:

                     (a)  the amount specified in subsection 3(11) ; or

                     (b)  the amount specified in subsection 56(4).

"relevant year" means the period of 12 months commencing on 1 July 1990, and each subsequent period of 12 months.

             (2)  Subject to subsection (3), if at any time, whether before or after the commencement of this section, the Australian Statistician has published or publishes an index number in respect of a quarter in substitution for an index number previously published by the Australian Statistician in respect of that quarter, the publication of the later index number is to be disregarded for the purposes of this section.

             (3)  If at any time, whether before or after the commencement of this section, the Australian Statistician has changed or changes the reference base for the Consumer Price Index, then, for the purposes of the application of this section after the change took place or takes place, regard is to be had only to the index numbers published in terms of the new reference base.

             (4)  Where the factor ascertained under subsection (5) in relation to a relevant year is greater than one, this Act has effect as if for each relevant amount there were substituted, on the first day of that relevant year, an amount calculated by multiplying by that factor:

                     (a)  in a case to which paragraph (b) does not apply--the relevant amount; or

                     (b)  if, by virtue of another application or other applications of this section, this Act has effect as if another amount or amounts were substituted for that relevant amount--the substituted amount or the last substituted amount, as the case requires.

             (5)  The factor to be ascertained for the purposes of subsection (4) in relation to a relevant year is the number (calculated to 3 decimal places) ascertained by dividing the index number for the March quarter immediately preceding that relevant year by the index number for the March quarter immediately preceding that first‑mentioned March quarter.

             (6)  Where the factor ascertained in accordance with subsection (5) in relation to a relevant year would, if it were calculated to 4 decimal places, end with a number greater than 4, the factor ascertained in accordance with that subsection in relation to that relevant year is taken to be the factor calculated to 3 decimal places in accordance with that subsection and increased by 0.001.
