Question 1(a): meaning and effect of s 29(1) of the Acts Interpretation Act
21 Section 29(2) of the AAT Act relevantly provides that the time within which a person may lodge an application for review with the Tribunal is "the period commencing on the day on which the decision is made and ending on the twenty-eighth day after … the day on which a document setting out the terms of the decision is given to the applicant".
22 Section 103X of the Child Support (Registration and Collection) Act 1988 (Cth) requires the SSAT, within 14 days of any decision on a review, to give written notice of the decision to the parties.
23 Section 28A of the Acts Interpretation Act relevantly provides that where any Act requires a document to be served on a person, whether the expression "serve", "give" or "send" or any other expression is used, the document may be served on a natural person by leaving it at, or sending it by pre-paid post to, the address of the place of residence or business of the person last known to the person serving the document.
24 Section 29 of the Acts Interpretation Act provides:
Meaning of service by post
(1) Where an Act authorises or requires any document to be served by post, whether the expression "serve" or the expression "give" or "send" or any other expression is used, then the service shall be deemed to be effected by properly addressing, prepaying and posting the document as a letter and, unless the contrary is proved, to have been effected at the time at which the letter would be delivered in the ordinary course of post.
(2) This section does not affect the operation of section 160 of the Evidence Act 1995.
25 The Decision recorded the date the Decision was posted as 13 June 2013. The covering letters to the appellant and the other party were dated 13 June 2013.
26 There was a dispute before me as to whether the reasons for decision were before the Tribunal. More importantly, however, it is plain that the Tribunal implicitly found that the reasons for decision were in the envelope under the cover of the letter from the Deputy Registrar of the SSAT dated 13 June 2013. The letter to the appellant refers to the "decision and reasons enclosed".
27 The appellant's evidence was that the envelope he received contained the letter and "documents". These likely were the Decision and reasons. I have proceeded on that factual basis.
28 The Tribunal (at [31]) concluded that written notice of the Decision was sent by pre-paid post to the address of the appellant on 13 June 2013. The Tribunal (at [32]) concluded, pursuant to s 29(1) of the Acts Interpretation Act, that service of the SSAT Registry's letter dated 13 June 2013 (Thursday), and the enclosed copy of the Decision and reasons, was deemed to have been effected at the time at which it would have been delivered in the ordinary course of post, namely on 17 June 2013 (the following Monday).
29 The Tribunal considered whether "the contrary [was] proved". It concluded that it was not. The Tribunal rejected the appellant's evidence that he did not receive the Decision until 28 June 2013: at [33]. In so finding, later in the Tribunal's reasons, when considering the same explanation by the appellant as to when and the circumstances in which he received the Decision, the Tribunal stated as follows at [41]:
In the Tribunal's opinion, the explanation provided by the applicant, in his abovementioned affidavit and in his oral evidence (see paragraphs 18-19 above), for not lodging with the Tribunal his application for review of the SSAT's decision of 5 June 2013 until 26 July 2013 is unsatisfactory.
30 The Tribunal concluded that his evidence in this respect was an implausible self-serving reconstruction and rejected it.
31 The error of law contended for under Question 1(a) has not been established.
32 The appellant relied upon the provisions of s 160 of the Evidence Act 1995 (Cth) (Evidence Act).
33 Section 160(1) of the Evidence Act provides that:
It is presumed (unless evidence sufficient to raise doubt about the presumption is adduced) that a postal article sent by prepaid post addressed to a person at a specified address in Australia or in an external Territory was received at that address on the fourth working day after having been posted.
34 The appellant submits that s 160, which is applicable to federal courts, affords a presumption as to when the article is to be taken to have been delivered, namely on the fourth working day after posting.
35 The respondent submits that there is doubt as to whether s 160 has application in this case.
36 It is not apparent that any submissions were put to the Tribunal as to the applicability or otherwise of s 160. The provision is not mentioned in the Tribunal's reasons. In any event I am of the opinion that s 160 has no application to the Tribunal.
37 The Evidence Act by s 4(1) relevantly provides that the Act applies to all proceedings in a federal court. "[F]ederal court" is defined in the Dictionary to the Evidence Act and includes within its meaning, relevantly, a body that, in performing a function or exercising a power under a law of the Commonwealth, is required to apply the laws of evidence. The Tribunal is not such a body. The procedure in the Tribunal is governed by its constituting legislation, the AAT Act. By s 33(1)(c) of the AAT Act the Tribunal is not bound by the rules of evidence but may inform itself on any matter in such manner as it thinks appropriate.
38 It follows that the Tribunal is not a "federal court". It is not a body required to apply the laws of evidence. Accordingly s 160 has no application.
39 In any event, even if the four day presumption in s 160 of the Evidence Act applies, rather than the ordinary course of post being two days, the appellant was still out of time with his Tribunal application. Service would be presumed to have been effected on 19 June 2013.
