Commonwealth Consolidated Regulations Commonwealth Consolidated RegulationsIn these Regulations, a period expressed in months and dating from an event, ends:
(a) on the day, in the relevant subsequent month, which has the same number as the day of the event; or
(b) if the relevant subsequent month has no day with the same number--on the last day of the month.
Note: This provision expresses a contrary intention to section
2G and subsection 36(1) of the Acts Interpretation Act 1901 , and is in
accordance with the Madrid Protocol. The difference between the two
occurs when the initiating event is on the last day of a calendar month, which
has fewer days than the month in which the period ends. For example, a
period of 3 months from an event on 30 September ends on 30
December under this rule; it would end on 31 December under the
Acts Interpretation Act 1901 provisions.
