150 Another instructive aspect of equitable practice is afforded in relation to the question of whether an ex parte injunction should be granted at all. It was summarised thus by Lord Hoffmann, delivering the opinion of the Privy Council in National Commercial Bank Jamaica Ltd v Olint Corporation Ltd :
'Although the matter is in the end one for the discretion of the judge, audi [alteram] partem is a salutary and important principle. Their Lordships therefore consider that a judge should not entertain an application of which no notice has been given unless either giving notice would enable the defendant to take steps to defeat the purpose of the injunction (as in the case of a Mareva or Anton Piller order) or there has been literally no time to give notice before the injunction is required to prevent the threatened wrongful act. … Their Lordships would expect cases in the latter category to be rare, because even in cases in which there was no time to give the period of notice required by the rules, there will usually be no reason why the applicant should not have given shorter notice or even made a telephone call. Any notice is better than none.'"
Serious question to be tried
7 I am satisfied that there is a serious question to be tried. According to the council's evidence, the respondents have carried out the works in breach of conditions of a development consent granted by the council to the first respondent in respect of a subdivision, and in breach of the terms of the subdivision construction certificate.
8 Conditions 3(a) and (c) of the development consent were in the following terms:
"3. To ensure satisfactory roads and drainage works are constructed, the following engineering conditions apply.
(a) construction of five metre bitumen sealed pavement together with 0.5 metre shoulder and necessary culverts and table drain within the proposed road reserve, to the requirements of the Engineering Works Manager.
...
(c) For the effective control of erosion and sedimentation from the subdivision, the areas of disturbance are to be minimised wherever possible. The retention of maximum ground cover and natural vegetation is critical. Therefore the applicant is advised that no clearing or under-scrubbing is to be carried out without direct consultation and direction from Council Officers and the Department of Conservation and Land Management. Any clearing works carried out without the approval of Council will cause all work within the development to be stopped until control measures have been employed."
9 On 7 October 1999 a subdivision construction certificate was issued under the Environmental Planning and Assessment Act 1979 which approved works on the road running through the proposed subdivision only from chainage 30 to chainage 180, a distance of approximately 150 metres. This constituted only a relatively small length of the road the subject of the development consent.
10 The evidence supports the council's contention that there has been a breach of the development conditions and the terms of the construction certificate in that the clearing of the road seems to have been carried out for virtually its full length and to a far wider extent than that which was permitted.
Balance of convenience
11 As for the balance of convenience, the evidence indicates that the allegedly unlawful works continued after the council issued a cease-work notice and that the works have caused and are continuing to cause environmental damage.
12 On 4 March 2010, the council served a cease-work order both personally on the plant operator on the site as well as by registered mail on each of the respondents. Clean-up notices were issued on 5 March 2010 and 21 May 2010. On 10 May 2010, a council inspection indicated that further works had been carried out. On 7 June 2010, a further council inspection did not reveal any additional clearing, but indicated that one of the existing silt fences was engorged with silt and a number of the fences required re-staking; two dams on the property were full and scouring had occurred around the outlet pipe; erosion and sediment controls on the property were inadequate and not being maintained; and soil and sediment had been washed from exposed areas into the surrounding vegetation. The evidence indicates that runoff of sediment and soil from land which has been cleared has the potential to impact on a State Environmental Planning Policy 14 Wetland and endangered ecological communities in a number of ways. There is evidence that immediate action needs to be taken to minimise or prevent further erosion and sediment runoff from the property into this wetland from the clearing and earthworks carried out on the property.
13 In the circumstances indicated by the council's evidence, particularly the need to take immediate action to protect the environment, I am persuaded that the balance of convenience favours the grant of an ex parte interlocutory injunction for a very short period until the next sitting day of the Court when the respondents will have the opportunity to be heard.
