1. Inspectors appointed by an enforcing authority under section 19 HSWA have extensive powers to carry into effect any of the relevant statutory provisions.1 The powers set out in sections 20(2) and 25 HSWA include powers to:
2. Inspectors are also given any other power which is necessary for the purpose of carrying into effect the relevant statutory provisions.12
3. These powers are wide-ranging and it is a matter for your discretion as to whether, and in what circumstances, you exercise them. You may be able to obtain any evidence you require voluntarily, without recourse to your powers.
4. As a public authority, HSE must act in a way that is compatible with the European Convention on Human Rights (ECHR).13 You should be mindful that use of your powers may interfere with the human rights of a person (including a corporate body), such as the right to respect for a private life, home and correspondence, and the right to peaceful use of personal property.
5. Any use of your powers must be necessary, justified and proportionate: see Judge over HSE’s shoulder for further guidance. You should record any decision to exercise your powers, together with the reasons for it.14 In major investigations, it may be appropriate to record the decision and supporting reasons in the key decision log.
6. Whenever you use or seek to use any of your powers, you must produce your warrant if asked.15
7. If you obtain evidence improperly, for example by exceeding any of the powers set out in HSWA, by failing to follow a PACE Code when required to do so, or by acting in a way that is incompatible with the ECHR, a court may rule that the evidence would have such an adverse effect on the fairness of the proceedings that it should not be admitted in evidence. Any unjustified use of your powers could also provoke a civil action for damages. 16 If the impropriety is sufficiently serious, it may form the basis of an abuse of process argument.
8. You have the power to require any person to produce any books or documents required to be kept under any of the relevant statutory provisions, and any other books or documents which are necessary for you to see for the purposes of your investigation. 17 This would include any document which assists you in deciding whether you should prosecute.
9. You have the power to inspect and take copies of such documents. If you do not take a copy, you should carefully note the contents in your notebook. Section 20(2)(k) does not give you the right to seize original documents. If you need to do this, you should refer to the section on 'Original documents or copies?'.
10. Where you do not have access to copying facilities on site, you may need to remove the original for copying. In such cases, you should give a responsible person a notice on form LP24, identifying the document and stating that you have taken possession of it using your s.20 powers 18 but will return it as soon as the necessary copy has been made. You should record in your notebook as to why you took the original for copying and also note when you returned the original.
11. You may have to go back and ask a witness about documents or objects that you have subsequently obtained. If you have already taken a statement from the witness, you may have to take a further statement to record their response.
12. For example, where a document has been produced by a potential defendant to show the steps taken with regard to safety, you should refer these to any witness who should have been aware of those steps or protected by them, in order to discover whether they knew of the document and whether such steps were in fact taken.
13. You may also wish to ask your expert to comment, for example, on whether measures had been taken to reduce the risk so far as was reasonably practicable.
14. Section 20(2)(j) allows inspectors to seek and obtain information. In normal circumstances, you will seek to obtain the information by interviewing a person and taking a witness statement. However, if this is not possible or appropriate, the section entitles you to seek and, if necessary, require information in writing, for example by correspondence. 19
15. Generally, it is not the computer itself which is evidence in a case, but the information held within the computer. In straightforward cases, if you require information which you know is held on the computer, you should ask the duty holder to print out the information for you, using section 20(2)(m) powers.
16. You should ask the duty holder if the computer is working properly as far as s/he knows. In less straightforward cases (for example, where you need to prove that an entry was falsely dated, or in cases where the duty holder is not cooperative), you may need to take a computer expert with you, using section 20(2)(c) powers, who can examine it and extract any necessary information.
17. Greater interference with a computer, such as seizure, will need to be carefully considered. Whether section 20(2)(m) permits interference in any particular case will depend on whether use of the power would be necessary, justified and proportionate. Alternative courses of action should be considered; for example, in an exceptional case, where a large amount of relevant material was known to be held on computer, you may consider using your power under s.20(2)(m) to direct a computer expert to ‘image’ the computer’s hard drive and take the image away to obtain the necessary material. This would reduce the impact of your actions on the duty holder as the computer would be unavailable for the minimum length of time. In each case, however, you would also need to consider how to preserve, and ensure continuity of, any evidence.
18. Requests for specialist help should be done through the normal channels in your Directorate/Division.
19. You have power to direct that the premises, or any part of them, or anything in them, be left undisturbed for so long as is reasonably necessary for the purpose of your investigation. 20 This power may be exercised, for example, where:
20. You may be able to arrange informally with a duty holder that the item or area is left undisturbed, but where you are not certain that s/he will comply, you should issue a formal notice. A formal notice to leave undisturbed should be in writing and include:
21. You should not rely on the fact that an employer is going to obtain a report on equipment, because that report may be the subject of legal professional privilege and therefore may not be disclosed to you. "Legal professional privilege" is considered in more detail later in this section.
22. You have power to take possession of any article or substance which appears to you to have caused, or to be likely to cause, danger to health or safety in order to examine it, ensure that it is not tampered with, or ensure that it is available for evidence in a prosecution. 21
23. When you do so, you must leave a notice with a responsible person at the premises or, where this is impracticable, fix the notice in a conspicuous position:
24. Unless it is not practicable, before taking possession of an article or substance using your s.20(2)(i) power, you should leave a marked sample of the substance or article with a responsible person on the premises. 23
25. You have power to take samples of any articles or substances and to take atmospheric samples. 24 The occupier or other responsible person must always be informed of the intention to take samples for analysis.
26. When the sample has been collected it should be divided into three parts. One part should be given to the occupier, another sent for analysis and the third retained by the inspector.
27. Each item must be uniquely identified by a label and recorded, using the proper containers, packing, labels and seals. The labels should state the premises of origin, a description of the sample, a number (if there is more than one sample), the date, and your name and title.
28. Samples are dealt with in more detail in "Expert Evidence".
29. You have the power to dismantle, or subject to any process or test, any article or substance which appears to you to have caused, or be likely to cause, danger to health or safety. 25
30. Where any person responsible for the premises from which the article was taken asks to be present when the dismantling or testing is carried out, this should be allowed. 26 You should also contact them if the test will irreversibly alter the article to give them an opportunity to be present.
31. So far as possible, you should retain enough of the item to facilitate further independent tests. If this is not possible, you should video, photograph or otherwise record the test to ensure that the results can be proved in court.
32. You have the power to take such measurements and photographs, and to make such recordings, as you consider necessary to your investigations. 27
33. All the circumstances surrounding the taking of a sample or the taking possession of an article for tests should be noted carefully in your notebook and included in your statement.
34. HSWA does not include a power of search and seizure. If you enter premises using your section 20 powers, the Police and Criminal Evidence Act 1984 Revised Code of Practice B on search and seizure does not apply (Code B, paragraph 2.5).
35. However, very rarely, circumstances may arise where, for the purposes of your investigation, you wish to conduct a search. In such circumstances, you could only do so with consent and you would have to follow those provisions of Code B that relate to voluntary searches.
36. These include a requirement that you secure written consent from a person entitled to grant entry to the premises. Before seeking consent, you should inform the person of the purpose of the proposed search, that s/he is not obliged to consent and that anything seized may be produced in evidence.
37. Searches must be conducted at a reasonable hour, only to the extent necessary to achieve the object of the search and with due consideration for the property and the privacy of the occupier. A search record will need to be made setting out the details identified in paragraph 8.1 of the Code. If you consider that a search of premises is necessary in a particular case, you should first seek legal advice.
38. Your powers under section 20 cannot compel the production of documents which are entitled to be withheld on grounds of legal professional privilege. 28
39. There are two types of legal professional privilege: advice privilege and litigation privilege.
40. Legal advice privilege extends to all confidential communications between a lawyer and client that are made for the purpose of giving or obtaining legal advice.29 This can include statements, reports and other information. Legal advice privilege does not cover communications sent to or from a third party.30
41. Litigation privilege extends to documents created for the dominant purpose 31 of existing or contemplated adversarial legal proceedings (such as civil litigation or criminal proceedings but not, for example, investigative inquiries).
42. Litigation privilege attaches to communications between solicitors and expert witnesses, including any written expert report which has been prepared for a dutyholder's solicitor in contemplation of legal proceedings. The expert's opinion on the case may not be privileged, depending on whether that opinion was based on consideration or privileged material or discussions, and there may be occasions where HSE can still call a dutyholder's expert to give oral evidence or put our own questions to them, even if we cannot access their report due to privilege. If you are considering this, it would be wise to speak to either LAO / your instructed solicitor agent. However, you should also note the requirements relating to disclosure of expert evidence in criminal proceedings: guidance can be found in the section 'Approach to common categories of material', both for investigations commenced before 4 April 2005 and those begun on or after 4 April 2005.
43. The privilege belongs to the client and not the lawyer; a duty holder has the ability to waive any privilege and show you the document in question, for example to assist, or to cooperate with, your investigation. Similarly, a client may choose to waive privilege in order to use the document in evidence.
44. If a company has prepared an incident report, litigation privilege may be claimed if the dominant purpose of creating the document was to obtain legal advice in relation to legal proceedings. An engineer’s report, for example, that was obtained for the purpose of deciding whether to contest proceedings (civil or criminal) will be protected by privilege. However, this will not be the case if the report was prepared simply because there had been an incident 33, or to avoid further incidents. In such circumstances, you are entitled to require production of the report if it is necessary for the purposes of carrying into effect any of the relevant statutory provisions. 34
