Expert Witness Reports - a Guide for Solicitors

Parameters of a Court-Compliant Expert Witness Report

The preparation of a Golf Expert Witness Report is governed by the Civil Procedure Rules (CPR), in particular Part 35.

An expert report must maintain clinical detachment and neutrality. A report that appears partisan, or which lacks the requisite independence, risks being rejected by the court and undermines the evidential value of the report.

Reports are often unsuccessful where they are prepared as generic health and safety audits, rather than as specialist expert evaluations suitable for litigation.

An inadequate and unsuitable risk assessment is frequently insufficient in technical scope for the issues in dispute, including ball flight trajectories and the relevant features of golf course design.

A court-compliant expert report should be grounded in empirical data and relevant, published design guidance, together with clearly stated safety margins.

The distinction between an operator’s internal risk assessment and an expert report for the purposes of Part 35 is critical for legal practitioners.

FREQUENTLY ASKED QUESTIONS.

What is a CPR Part 35 Compliant Expert Witness Report?

A CPR Part 35 compliant expert report is an evidentiary document prepared in compliance with the Civil Procedure Rules governing expert evidence in England and Wales. It prioritises the expert’s overriding duty to the court. The report must include a formal Statement of Truth and a declaration of the expert’s qualifications.

What is the Statement of Truth and the professional duty?

The Statement of Truth is a mandatory component of the report. It confirms that the expert understands and complies with their overriding duty to the court and that facts and opinions are expressed properly, honestly and to the best of the expert’s knowledge.

What are the legal implications of non-compliant evidence?

Where an expert report fails to comply with the formatting, disclosure and evidential requirements under CPR Part 35, the court may order that the report be struck out. Such failures can adversely affect the prospects of establishing breach of duty, and may leave the instructing party without adequate technical evidence necessary to prove an alleged duty of care breach.

What is the technical methodology and analysis in golf accident investigation?

A court-compliant golf expert report requires a comprehensive physical inspection of the locus.

Desk-based review using satellite or aerial imagery is unlikely to capture relevant topographical variations, the precise orientation of teeing areas, and the site-specific factors affecting visibility.

On-site, site geometry is assessed to determine whether the course design aligns with published safety margins. This includes consideration of a “safety cage”, being the area in which commonly hit shots are expected to land.

The physical findings should be cross-referenced to the requirements of CPR Part 35 documentation, to ensure the methodology and conclusions remain properly evidenced and legally defensible.

How is the site geometry and layout of hazards analysed?

The proximity of golf holes and the layout of course boundaries are recurring areas of dispute in golf-related litigation.

The report should assess lateral separation between fairways and the proximity of the layout to relevant boundary features.

Hazards are ordinarily integral to course design and may influence the designed line of play, which may not coincide with the centreline of the hole. The report should address the implications of hazards for the location and mechanism of the alleged incident.

Where safety netting or fencing is present, its height, permeability, and structural integrity should be evaluated against the trajectory of shots from the relevant strike points. Natural barriers (including tree lines) should also be assessed; however, their protective effectiveness must be evaluated against the technical requirements of safe containment.

Can ball flight and impact dynamics be recreated?

Forensic reconstruction requires assessment of likely ball speeds and resultant impact forces. Golf ball impacts from drivers can exceed 160 mph, with sufficient kinetic energy to cause serious injury or death.

While ball-flight data exists and can inform reconstruction, the dynamics of impact are inherently more difficult to model reliably. Accurate prediction of impact speed and exact impact location is often not susceptible to complete certainty.

Some aspects can be partially predicted, such as the potential for rebound or ricochet where a ball impacts a hard surface in its path.

What is foreseeability and risk mitigation in golf design?

Foreseeability is assessed by reference to the frequency and pattern of prior incidents, considered alongside the physical geometry of the site and relevant design guidance.

The report should address whether reasonable steps were taken to mitigate identified risks.

Where evidence indicates that a club or operator was aware of a high number of errant shots entering a specific zone, but failed to implement protective measures, the evidential basis for breach may be strengthened.

The assessment of whether a specific strike was reasonably foreseeable should consider the course layout in conjunction with typical player behaviour and reasonable skill levels.

Where relevant, environmental variables (including prevailing wind direction and sun glare at relevant times) should be incorporated into trajectory analysis.

Warning signage, documentation, historical incident logs, and maintenance records may provide necessary context.

A documented pattern of errant shots into a specific zone may indicate a systemic design or operational deficiency rather than an isolated player error. Where appropriate, the report should also address the evidential reliability of alleged monitoring, recording and reporting arrangements.

On the basis of the above, and applying the relevant standard of care, the report should address whether breach is established for the issues in dispute.

Are liability and negligence dealt with in an expert report?

The primary purpose of the expert report is to provide the court with a technical basis for determining whether a breach of duty has occurred.

Liability analysis requires an evaluation of the defendant’s conduct against the “standard of care” expected of a reasonable golf course operator (or other relevant party) in the circumstances.

The report should address whether hazards were identified through a suitable and sufficient risk assessment, and whether subsequent amelioration, mitigation or elimination measures (such as signage or structural barriers) were adequate to discharge the duty of care owed to players and members of the public.

The report should distinguish between inherent risks of the sport and actionable negligence.

The expert’s role is to determine whether the incident resulted from an unavoidable accident, a failure to address a design deficiency, negligence, or a breach of duty of care.

How does the Occupier’s Liability Act affect public safety?

Where non-golfers are involved, the claim may engage occupier’s liability principles under the Occupier’s Liability Acts 1957 and/or 1984 (as applicable).

A report would address the adequacy of warnings and any protective measures implemented by the club or operator. Similar issues may arise for driving ranges, where increased density of play may increase the likelihood of an incident.

Legislation is dealt with in greater detail in an article entitled Safety Legislation on the Insights page.

What is the instruction process for solicitors?

Solicitors should set clear timeline expectations for the provision of a court-ready report, particularly where deadlines have been fixed or are approaching.

In complex cases, an early preliminary evaluation may assist in identifying technical strengths and weaknesses prior to commissioning the full Part 35-compliant report, supporting an efficient and cost-effective approach to litigation.

What is the timing and instruction for litigation and insurance matters?

Solicitors should provide a clear written instruction defining the technical questions the court requires to be answered.

This ensures that the report remains focused on liability-related issues and avoids extraneous material. Full disclosure of relevant documents is required for an objective and properly evidenced analysis.

Under CPR Part 35, experts may be required to participate in discussions to produce a joint statement identifying agreed issues and areas of disagreement, thereby narrowing the matters for determination.

During meetings with counsel, the expert should provide the technical foundation for argument, consistent with the expert’s overriding duty to the court.

Is there support for insurers and claims handlers?

Insurers and claims handlers may use expert reports to assess the merits of allegations by reference to technical evidence rather than untested assertions.

Where liability is disputed, the expert’s technical evidence should provide the evidential basis for responding to allegations of negligence.

Can technical rigour support judicial admissibility?

Disputes are resolved by the movement from anecdotal assertions to evidence-based analysis suitable for scrutiny.

The expert report should provide a meticulous reconstruction of risk, anchored to the relevant technical methodologies and standards appropriate for UK civil courts.

The report should be prepared by an expert with appropriate depth of expertise in UK and international golf-related litigation, and must strictly adhere to CPR Part 35 requirements to withstand robust cross-examination.

Why is a specialised golf expert required for personal injury claims?

Specialised expertise is required because golf litigation involves technical variables, including ball flight trajectories and site-specific safety margins. A general health and safety consultant may not have the forensic basis to quantify relevant risk areas or assess deviations from established safety guidance. A specialist golf expert report provides the technical analysis necessary to establish or refute breach.

Can a golf expert report be instructed by either party?

Yes. An independent expert may be instructed by either party. The report should remain neutral and objective to assist the court in reaching a fair determination based on evidence and analysis.

What documents are required to prepare a court-compliant report?

Preparation requires disclosure of all relevant documentation, including historical incident logs, maintenance records, and existing site risk assessments. Solicitors should also provide witness statements, site plans, and photographic evidence.

How long does it typically take to produce a golf expert witness report?

Reports typically take 10–15 working days to produce following the site visit, subject to case complexity and disclosure availability.

Does the expert need to visit the golf course in person?

Yes. A physical site visit is generally required for a court-compliant report, as desk-based review cannot reliably account for site-specific topography, orientation and visibility.

What is the difference between a risk assessment and an expert report?

A risk assessment is a proactive tool used by operators to identify and manage risks before an incident. An expert report for litigation is prepared after an incident and is directed to the court’s determination of breach, based on the standard of care and the evidence disclosed.

How is liability determined in an errant golf ball case?

Liability depends on whether the incident was a reasonably foreseeable consequence of a design flaw or operational failure, evaluated against the expected standard of care. The report should compare relevant safety margins and protective measures against appropriate guidance and identify whether reasonable steps to mitigate known risks were taken.
