[14] The Council has not prosecuted anyone for a development offence pursuant to Division 4 Part 3 of IPA, nor did it give the respondents an enforcement notice pursuant to s.4.3.11 of IPA. It is arguable that the time for prosecuting the respondents has now passed: s.4.4.2 IPA. A prosecution for an offence against s.4.3.3(1) attracts the criminal standard of proof. Council has elected to proceed by way of declaratory relief pursuant to s.4.1.21 of IPA. Mr Couper, senior counsel for the Council, submits that these proceedings are civil in nature and that the civil standard applies. He concedes that given the serious consequences to the respondents of a finding of deliberate contravention, the top of the range in the sliding scale contemplated in Briginshaw v.Briginshaw [1938] HCA 34; (1938) 60 CLR 336 per Dixon J at 362-3 is appropriate. The respondents submit that the appropriate standard is the criminal standard, and rely on Gold Coast City Council v. California Court Pty Ltd [2000] QPELR 24 at 31, approved in Patterson v. Redland Shire Council & Anderson [2002] QPEC 68 at [6] and Mareeba Shire Council v. Laghaifar [1999] QPELR 179 at 180. In California Court, Newton DCJ seems to have assumed without discussion that the appropriate standard for the issue of an enforcement order based on the commission of a development offence was the criminal standard. In Patterson Britton SC DCJ followed California Court, again without detailed analysis; and on the basis there that the parties to the proceedings agreed that the criminal standard applied. In both cases, the applicants were seeking declaratory relief. In Laghaifar, Daly DCJ considered that in relation to the making of an enforcement order pursuant to s.4.3.25 of IPA, he was required to be satisfied to the criminal standard that (in that case) an offence will be committed unless restrained. The wording of s.4.3.25(1) "if the court is satisfied", does suggest to me that the draftsperson did turn his or her mind to the level of proof required, however no guidance as to the required standard is given in s.4.1.21. In my opinion, given the absence of binding authority on the point, as a matter of principle, relief sought under s.4.1.21 is classically civil in nature. The section is not penal. It is common ground that this Court's powers to make orders pursuant to s.4.1.22 (if satisfied that a development offence has been committed) does not include power to impose pecuniary or other penalties. The power to make orders pursuant to s.4.1.21 (including the orders sought in paragraph (g) of Council's application) is discretionary in nature, and, in Warringah Shire Council v. Sedevcic (1987) 10 NSWLR 335 at 341, in discussing the guidelines applicable to the exercise of such discretion, Kirby P seems to draw a distinction between proceedings of this nature and criminal prosecutions for (in that case) enforcement of environmental law in the public interest. In my opinion, the appropriate standard of proof is the civil standard subject to the Briginshaw sliding scale, and in my opinion having regard to the very significant consequences to the respondents of the making of the order sought in paragraph (g) of Council's application, the standard should be at the top of the range of that sliding scale. My conclusion is supported by the observations of Judge Robin QC in Crowther v. State of Queensland [2002] QPEC 79 in which his Honour was considering the same issue in the context of injunctive relief sought on the basis of alleged breaches of the Environmental Protection Act. In turn his Honour followed conclusions to the same effect of Judge Dodds in Caloundra City Council v. McGreath [1998] QPELR 178 at 182, and Judge Brabazon QC in Hawkins v. Izzard v. Permarig Pty Ltd & Brisbane City Council (No. 3) [2001] QPELR 423 at 429.
