A departmental investigator was asked in cross-examination what he had done to satisfy himself that a company had wilfully breached its environmental program, rather than merely breached it. He answered, “Just the mere fact that the requirements [were] not being complied with”, at [41]. He had not read the file, reviewed the history, or looked at the communications between the company and his own Department about difficulties in completing the works on time, including flooding in February 2022, at [39].
That answer sank the knowledge grounds, on which a summary prosecution time limit turned. In Chief Executive of the Department of the Environment, Tourism, Science and Innovation v Magistrate Kahlert & another [2026] QSC 217, delivered on 14 September 2026, Ryan J refused the Chief Executive’s application for an order in the nature of certiorari quashing a Magistrate’s dismissal of the complaint as out of time. The applicant pressed five grounds and lost every one.
The setting is environmental regulation, but the reasoning is not. Two questions in the judgment reach beyond it, wherever a statute lets the prosecution elect to take an indictable offence summarily and limits the time for doing so. Which limit applies once that election is made, and what must a complainant actually know before the clock starts to run?
What the Court decided
| Question | How it arose | What the Court held | Status |
|---|---|---|---|
| Does the time limit on summary proceedings apply where the offence charged is indictable? | Applicant’s ground 1 | Yes, once the prosecution elects to proceed summarily. “The time limit was triggered by the procedural choice made by the complainant”, at [56] | Held. Ground failed |
| Does s 495(2), which lets the defendant or the Magistrate override the election, disapply the limit? | Applicant’s argument on grounds 1 and 2 | No. It “does not affect the time limitation on the commencement of proceedings for an indictable offence where there has been an election made to proceed summarily”, at [23] | Held. Ground failed |
| What turns on the complaint being in time? | Consequence of the above | Jurisdiction. The Magistrate “only had jurisdiction to hear the complaint if it was made within the time prescribed by section 497(b)”, at [21] | Held |
| Are s 432(1) and s 432(2) one offence with an aggravating mental element, or two? | Necessary to identify the relevant offence | Two separate offences. “The inclusion of section 432(3) makes this plain”, at [31] | Held |
| What does “wilfully” add? | Applicant’s grounds 4 and 5 | A culpable state of mind as to the result, distinct from a willed act under s 23(1)(a) of the Criminal Code. It “elevates, as it were, the lesser offence in sub-section (2) to the indictable offence”, at [48] | Held. Grounds failed |
| Is knowledge of a contravention enough to start the clock on a charge of wilful contravention? | Applicant’s ground 6 | No. “The relevant knowledge required by the complainant was knowledge of the commission of the section 432(1) offence”, at [71] | Held. Ground failed |
No single ground decided the case. Six were advanced and five pressed, each disposed of separately, and the conclusion is two sentences at [73]. “None of the grounds are made out. The application is refused.”
The election switches on the time limit
An offence against s 432(1) of the Environmental Protection Act 1994 (Qld), wilfully contravening a transitional environmental program, carries a maximum of 6,250 penalty units or five years’ imprisonment. Because the maximum term is two years or more, it is an indictable offence under s 494(1). Section 495(1) lets the prosecution elect to take the proceeding summarily under the Justices Act 1886 (Qld) or on indictment.
Ground 1, and the first limb of ground 2, were that because the offences charged were indictable, no time limit applied at all. The second limb of ground 2, that the complaint was in time, was referred to grounds 4, 5 and 6, at [58]. The Court rejected the premise of the first. Section 497 opens with the words “A proceeding for an offence against this Act by way of summary proceeding”, and an offence against the Act includes an indictable one, at [53] and [54]. The election, not the character of the offence, is what engages the limit. At [56], “The characterisation of the offence as an indictable offence against the Act did not determine whether the time limit applied or not.”
The fallback was s 495(2), under which a Magistrate must not hear an indictable offence summarily if the defendant asks at the start of the hearing that it be prosecuted on indictment, or if the Magistrate considers that it should be. If the election can be overridden, the argument ran, it cannot fix the time limit. Reading the Act “reasonably, and as a complementary whole, and ensuring its workability”, Ryan J held at [23] that s 495(2) permits an already made election to be overridden, and does not touch the requirement that the complaint be made in time to ground jurisdiction.
In a footnote to [23] the Court added, expressly “[a]s an aside”, that this approach “is seen in numerous pieces of Queensland legislation”. That is not a holding, and no other statute was identified or construed.
Knowledge of which offence
The limitation provision that governed this complaint required a proceeding to start within one year after the commission of the offence, or within one year after the offence came to the complainant’s knowledge but within two years after its commission. Only the second limb was in play, at [9] and [10].
Two propositions about that knowledge were uncontentious, at [27]. It is “knowledge of facts sufficient to establish the offence, which was something more than having reasonable grounds for suspecting it”, citing Cross Country Realty Pty Ltd v Peebles [2006] QCA 501 at [10]. And a complainant acquires it only when they have before them such information as gives them reasonable grounds for that belief.
The live question was knowledge of which offence. Section 432 creates two. Subsection (1) is wilful contravention, indictable. Subsection (2) is contravention, carrying a lower monetary maximum and no imprisonment. The sixth ground argued that because s 432(3) lets a court not satisfied of the wilful offence convict of the simpliciter offence instead, it was enough to know facts constituting the elements of a particular offence under s 432.
That failed at its first step. The two subsections create two separate offences, not a base offence with wilfulness as a circumstance of aggravation, and s 432(3) exists precisely because the lesser offence is not the natural alternative to the greater, at [31]. So the relevant offence for the limitation provision was the one charged, at [32] and [71].
The applicant’s authority was Witheyman v Van Riet [2008] QCA 168, where Fraser JA held that a complainant can know an offence has been committed without knowing who committed it. The applicant read [15] as establishing that knowledge of facts constituting the elements of a particular offence under a section will do. Ryan J disagreed at [63], on the ground that the argument “misconceives and overvalues” the passage. In Witheyman the only thing not known was the identity of the offender, which at [67] is “obviously an element of a different kind from those which make up the offence itself”. The legal elements there were known, at [68]. Carrying the passage further “unreasonably attempts to stretch its ratio”, at [70]. Witheyman is confined, not doubted.
“Wilfully” is not the same as “willed”
The most portable part of the judgment is the shortest. Schedule 4 defines “wilfully” to mean intentionally, recklessly, or with gross negligence. The applicant contended that knowledge of that element did not require “a great deal of intellectual analysis”, and asked rhetorically what more one would expect the investigator to say, at [45].
At [46] Ryan J found that the applicant and the investigator “appear to have confused the notion of ‘wilfully’, which in this context is a culpable state of mind as to a result, with the notion of a willed act” as understood under s 23(1)(a) of the Criminal Code. At [47] the Court said that “at least prima facie” the company controlled its own action or inaction, so in that sense the conduct was willed, while footnote 11 left open whether it might have argued otherwise at a trial. Either way, that tells you nothing about its state of mind towards the resulting contravention. Wilfulness, at [48], “elevates, as it were, the lesser offence in sub-section (2) to the indictable offence”, and at [49] it requires an intention to contravene, recklessness as to a foreseeable substantial risk of contravention, or gross negligence as to a foreseeable risk of it.
The consequence is at [51]. There was “simply no evidence sought out by him or obtained by him” going to any of those three states of mind. Reasoning from the bare fact of contravention to knowledge of a wilful contravention was flawed, at [60], and the Magistrate’s finding was not merely available but, at [61], “it was the only finding available on the evidence”.
One observation runs the other way, and it is obiter. Had the Magistrate reasoned to wilfulness from the bare fact of contravention, “then her Honour would have been in error”, at [61].
The provision has changed, but not for older offences
The Court construed s 497 as in force when the complaint was filed on 15 May 2024, with its one year from knowledge limb. In a footnote to [19] it noted that the section “has since been amended and simplified” so that a summary proceeding “must start within two years after the commission of the offence”.
That describes s 497(1) of the amended section, which commenced on 16 June 2026. The section also contains s 497(2) and (3), under which a “relevant summary proceeding” must start within three years after commission, s 497(3)(a) defining that term to include a summary proceeding for an indictable offence against the Act.
None of which retires the knowledge reasoning, and this is the trap. Section 846, inserted by the same amending Act, provides that where the offence was committed before the commencement, “[f]ormer section 497 continues to apply in relation to starting the proceeding as if the amendment Act had not been enacted”. For every offence committed before 16 June 2026 the old two-limb section, knowledge limb and all, remains the governing law, and this decision construes it. The three-year limit reaches offences committed on or after that date.
The reasoning about the election, about jurisdiction, and about the difference between wilfulness and a willed act does not depend on which version applies. Where another statute uses materially similar language and has a comparable offence structure that reasoning may assist by analogy, but it does not govern, and the Court construed no other enactment.
Questions this raises
Does charging an indictable offence avoid the time limit on summary proceedings?
No, not once the prosecution elects to proceed summarily. The Court held at [55] that the election did not change the character of the offences as indictable offences, but that the limitation provision applied because of it, and at [56] that the time limit “was triggered by the procedural choice made by the complainant”.
How is the prosecution’s election identified if nobody states it?
From the complaint and summons. At [20] the Court found it clear from that document that the complainant had elected to proceed summarily, because the company was commanded to answer the complaint rather than to appear before justices taking an examination of witnesses in relation to an indictable offence. Those are the two alternatives in s 54(1) of the Justices Act 1886 (Qld), and at [18] the Court said it is by the content of the complaint that the complainant informs the defendant of the choice.
Is knowledge of a contravention knowledge of a wilful contravention?
No. At [31] the Court held that s 432(1) and s 432(2) create two separate offences rather than one offence aggravated by wilfulness, and at [71] that the knowledge required was knowledge of the commission of the offence charged, which included wilfulness as an element. At [51] it found no evidence sought or obtained about the company’s state of mind. Whether the same analysis applies elsewhere depends on whether the provision creates separate offences or one offence with a circumstance of aggravation.
What does “wilfully” require beyond doing the act deliberately?
Under this Act, a state of mind about the result. Schedule 4 defines the word to mean intentionally, recklessly or with gross negligence, and at [49] the Court framed those as an intention to contravene the program, recklessness as to a foreseeable substantial risk of contravention, or gross negligence as to a foreseeable risk of it. At [46] the Court identified the error as confusing that with a willed act under s 23(1)(a) of the Criminal Code.
Does the decision hold that the company did nothing wrong?
No, and it decides nothing of the kind. The complaint was dismissed for want of jurisdiction on limitation grounds and there was never a trial of the charges. The findings are about what the investigator knew, and when, at [50] and [51]. Whether the program was contravened, wilfully or at all, was not determined.
What the judgment leaves open
Two things bear on how far the decision can be pushed. The first is at [72]. Ryan J recorded from the Magistrate’s reasons that the complainant did not argue that, because the offences had not yet come to his knowledge, the limitation period had not yet expired. That argument was not run and was not determined, so the judgment decides nothing about whether or when the clock might start in such a case. The provision as it then stood carried an outer limit of two years from commission in any event.
The second is in a footnote to [47], where the s 23(1)(a) question was described as a possible line of defence revealed in cross-examination but “not something I need to consider”.
Three smaller matters were also not determined. The Chief Executive accepted the averment was wrong but made no application to amend it, at [25]. The investigator’s explanation for nominating 18 May 2023 was not gone into, at [35]. Ground 3 was not pressed.
The conclusion is at [73]. The application was refused, and the applicant was ordered to pay the second respondent’s costs unless a party contacted the associate within seven days to contend otherwise. The reasons are on AustLII, and the current form of the limitation provision is in the current reprint of the Act.
