Work Instruction 8:
Assessment of Evidence





This work instruction describes how inspectors should assess evidence collected during the investigation.

reviewing the information and evidence collected to date to determine whether any conclusions drawn are supported by the information and evidence and are robust;
determining the value, quality and reliability of information and evidence collected so far;
cross-reference to the original objectives of the investigation to ensure they have been achieved;
determining whether further investigation is needed to achieve the objectives and/or to further establish the circumstances;
applying the principles of EMM to decide on any appropriate enforcement action;
enabling decisions to be made about stopping the investigation because the objectives have been achieved or further investigation is disproportionate in accordance with the examples given in the investigation policy.

There are four key activities

KA 1

Assessment and verification of information and evidence obtained

KA 2 Investigation review
KA 3 Informal review
KA 4 Application of EMM

Inspectors should also refer to the appropriate parts of the Enforcement Handbook - England and Wales, and the Enforcement Handbook - Scotland for guidance concerning taking statements and taking physical evidence. The Handbooks also contain information concerning liaison with and use of expert evidence which may be relevant to the investigation process.



Key activity 1

ASSESSMENT AND VERIFICATION OF INFORMATION AND EVIDENCE OBTAINED
2 Inspectors should continually assess the evidence collected in order to determine whether the objectives of the investigation are likely to be achieved (see Work instruction 1 Key activity 1). They should identify potential offence(s) at this stage. They should identify elements necessary to prove an offence(s) against existing evidence. Inspectors should also ask the following questions when assessing evidence; does it:
(1) establish the circumstances satisfactorily or do grey areas or inconsistencies exist?
(2) provide sufficient evidence to prove a breach, ie are all points to prove covered?
(3) provide sufficient information to establish no breach has been made?
(4) identify all reasonable lines of enquiry?
(5) identify any potential defences?
(6) contain sufficient support from other sources such as physical evidence and expert witnesses?
3 The following format of table may be useful when assessing evidence.

4 Assessment of evidence may identify other witnesses who may be able to offer more information concerning underlying causes/management issues, eg supervisors/managers. Evidence from such witnesses may add considerable value.
5 Inspectors should keep an open mind when assessing evidence and attempt to separate facts from preconceptions or opinions because reliance on the latter may undermine a later prosecution. Avoid dismissing evidence advantageous to any potential defendant. Ensure evidence against, is sufficient to overcome it.
6 Inspectors should also verify information and evidence obtained to date. Interviews with witnesses or statements will usually form the bulk of the information and evidence collected so far. It should be reviewed to ensure it is reliable and accurately reflects the circumstances.
7 The evidence of witnesses may not always be reliable. They may:
(1) be unable to remember key details;
(2) have an inaccurate perception of events; or
(3) be untrustworthy.
8 Inspectors should, so far as possible, and to the extent appropriate in the circumstances, determine the truth and accuracy of a witnessâs evidence by:
(1) checking it against the evidence of others and against independent facts;
(2) assessing and testing the probability and credibility of the allegations against other reasonable explanations for the incident;
(3) where necessary, planning to carry out further interviews with the injured person (IP) or others using suitable questioning techniques aimed at helping the interviewee overcome any difficulty in remembering details.
9 If the truth of any person's evidence is crucial to significant enforcement action, ie prosecution, inspectors should be careful to validate the evidence as described. Inspectors should remember that the conviction with which details are recounted is not a measure of their accuracy. If misleading evidence is not detected during an investigation it may have serious consequences for any prosecution resulting from the investigation.
10 When interviewing IPs, inspectors should be aware that historically, and rarely, IPs have been influenced by a potential civil claim, and to an extent have concealed their contribution to the accident. This contribution has varied from interfering with safety devices or equipment provided to failing to follow instructions.
11

The outcome of the assessment process could be one of the following:

(1)

Conclusion of the investigation due to

(a) no breach identified,
(b) insufficient evidence to prove a breach,
(c) not having a realistic prospect of conviction,
(d) breach identified but action by dutyholder since taken and application of the EMM do not justify action,
(e) disproportionate effort required to secure sufficient evidence,
(f) a defence likely to fatally undermine any case has been identified
(2) decision to propose prosecution on strength of evidence collected to date;
(3) target effort towards further investigation to establish the circumstances and/or to strengthen evidence pending potential prosecution;
(4) decision to pursue alternatives to prosecution such as notices, letter, advice.
12 Inspectors and their line managers should record and agree the reasoning behind any decision to suspend or terminate any investigation to justify action if questioned later.
13 Inspectors should consider other enforcement outcomes, when prosecution is not considered, such as notices, letters or advice in order to facilitate improvement. More investigation may be required for this purpose, eg to enable an inspector to gather further information demonstrating underlying management failures.
14

Inspectors should also give appropriate consideration to other enforcement outcomes such as:
(1) recommendation for a revocation of an asbestos licence if relevant to an investigation; or
(2) prosecution for a failure to have ELCI cover at the time of an incident.

Key activity 2

INVESTIGATION REVIEW

15 For more complex investigations, inspectors should review the investigation with their line manager. The factors outlined in paras 2-14 can be used to guide such discussion. Such discussions have benefits in that the line manager is kept informed of developments and progress and can monitor whether the investigation continues to be proportionate. Matters concerning inspector workload and stress can also be addressed. Decisions relating to the outcome, ie to conclude, abort, pursue further investigation etc can also be made. Sufficient information and evidence to complete a FOCUS investigation report (see Work instruction 9) which satisfies the objectives for the investigation and achieves relevant performance standards, will justify a conclusion.
16 An investigation review can benefit the inspector in that reasonable lines of enquiry can be confirmed or modified. Informal review can also play an important part in the review process (see Key activity 3).
17 If an investigation has not been completed after 2 months, a meeting between the line manager and the investigating inspector should take place. The purpose of the meeting is to carry out an investigation review, decide on future action and identify specific reasonable time-scales, which should normally be at 2-monthly intervals, after which another review will be undertaken if the investigation has not been concluded. The purpose of the review is to ensure an investigation does not stagnate and to take into consideration matters such as witness availability, inquest hearings and expert witness reports, when agreeing any extension.
18 The 2-month period is that period from the inspectorâs receipt of any notification of an incident to the achievement of the performance standards relevant to the investigation. The period also requires the completion of a report into the investigation which, depending on its complexity and enforcement outcome, may range from a FOCUS investigation report and associated contact entries, to full investigation/prosecution reports. If the report has not been completed at the 2-month review, then the inspector and line manager should agree an action plan for completion of the report. This should normally be within one month or in agreement with the line manager (see also Work instruction 9).

Key activity 3:

INFORMAL REVIEW

19 Inspectors should engage in informal review with colleagues, when appropriate, as it may help with the process of assessing evidence. An informal chat with colleagues can often help confirm or redirect your thoughts concerning an investigation.
20 Informal review is a means to improve consistency. It is also a vehicle for providing suggestions and constructive criticism to help progress the investigation. It is not just a tool for identifying weaknesses. Inspectors can cross-reference their views and actions with those of their colleagues to try and gain some sort of a consensus of opinion that the investigation is going along the right lines.
21 Reviews, particularly with experienced inspectors, and those in the sector can often introduce a fresh perspective and can help identify possible new lines of enquiry or expose potentially fatal flaws with information or evidence. They can help redirect or target an investigation and can often suggest useful sources of information, including guidance etc, to help focus investigative effort.

Key activity 4

APPLICATION OF EMM


22 The systematic application of EMM is defined by the procedure itself, eg all fatal accidents. Inspectors should apply the principles of EMM to all other investigations to facilitate the enforcement decision-making process in relation to the information and evidence obtained to date. See Enforcement Management Model.
23 Inspectors should apply the principles of EMM throughout the investigation procedure, eg establishing benchmarks; deciding on early enforcement action, eg PN. They will also apply the principles when they have obtained sufficient information and evidence from the investigation to enable judgements to be made concerning any risk gap and subsequent enforcement expectation.
24 Inspectors should then take into account local and strategic factors together with targets for action before making a final enforcement decision. A decision to enforce, may require further investigation to complete the evidence collection process. Following any further investigation, inspectors should apply the principles of EMM to facilitate final enforcement decisions.
25 Justification for concluding the investigation can now be agreed in consultation with a line manager providing all the circumstances are known and the risk of reoccurrence is removed or minimised. A decision not to enforce following the application of the principles of EMM, should result in a prompt and appropriate contact with the dutyholder, eg letter, advice or request for an action plan. Inspectors should also inform other interested parties, such as those directly affected, relatives and employee representatives.
26 Where the EMM has been applied systematically, a copy of the EMM proforma should be kept with the analysis papers. This should also include a record of any differences between the outcome indicated by the EMM, and the action proposed, along with the reasons for the final enforcement action.
