Part 1: Environmental Governance Chapter 2: The Office for Environmental Protection Section 34: Duty to keep complainants informed
This section deals with the procedure for the OEP to inform complainants about whether an investigation following a complaint will be carried out and the progress of the investigation.
	The OEP must inform the complainant if the complaint will not be considered for further investigation on the basis that it is not a valid complaint. For example, the complaint may not be concerned with a valid matter (a breach of environmental law by a public authority), it may not have been submitted in accordance with the specified procedure, or it may have been submitted after the time limit without any exceptional basis for the OEP to reasonably accept it. This is covered in subsection (2)(a) of this section.
	Where a complaint has been made in accordance with section 32, the OEP must inform the complainant about whether or not an investigation into that complaint will be carried out; this is covered in subsections (2)(b) and (c). This reflects the fact that the OEP has discretion in choosing which cases to investigate, prioritising cases in line with its enforcement policy.
	When a report on an investigation under section 33(5) has been provided to the public authority in question, paragraph (d)(i) requires that the OEP must inform the complainant of this, although it is not obliged to disclose that report to the complainant at that stage unless it has been published under section 33(9).
	Where the OEP applies for an environmental review, or for permission to apply for a judicial review, or statutory review in relation to the failure that was the subject of the complaint, paragraph (d)(ii) requires the OEP to inform the complainant.
	Where the OEP publishes a report following the investigation of a complaint, it must provide the complainant with a copy of that report as published in full or in part, as required by paragraph (e). This could be done by electronic means, or by referring the complaint to a published report that is available online, rather than necessarily requiring a hard copy of the report to be provided in every case.
