A Part 35 compliant report is an expert witness report prepared in accordance with the Civil Procedure Rules (CPR Part 35). It is designed to provide independent, professional evidence to assist the court in resolving disputes. The report must be impartial, evidence based, and clearly structured to meet legal standards.
CPR Part 35 sets out the rules governing expert evidence in legal proceedings. Its purpose is to ensure that expert opinions are independent, reliable, and focused on helping the court reach a fair and informed decision, rather than supporting one party’s position.
To be compliant, a report must include a clear statement of independence, full disclosure of methodology, supporting evidence, and a formal statement of truth. The expert must confirm that their duty is to the court and that their opinion is unbiased.
A standard witness statement presents factual evidence from an individual involved in a case, whereas a Part 35 report provides an expert opinion based on technical knowledge and professional experience. The expert’s role is to interpret evidence, not simply describe events.
A CPR compliant witness statement follows the Civil Procedure Rules for presenting factual evidence in court. It must be clear, relevant, and based on direct knowledge. Unlike expert reports, it does not include opinion unless the individual is acting as an expert under Part 35.
An expert witness must have relevant qualifications, experience, and recognised expertise in their field. This could include ecologists, arboricultural consultants, invasive species specialists, or environmental professionals, depending on the nature of the dispute.
No. An expert witness must be demonstrably independent and suitably qualified. Personal relationships or bias can undermine the credibility of the report and may result in it being challenged or dismissed by the court.
A Single Joint Expert is appointed by all parties in a dispute to provide one independent report. This approach helps reduce conflicting evidence, lowers the risk of dispute escalation, and supports a more efficient legal process.
Part 35 reports commonly address disputes involving Japanese knotweed, bamboo encroachment, tree damage or subsidence, land contamination, and environmental impacts. They are used where technical clarity is required to establish liability, causation, or future risk.
Evidence may include site inspections, survey data, historical records, mapping, photographs, and previous reports. The expert will analyse this information to form a clear, reasoned, and defensible professional opinion.
For evidence to be admissible, it must be relevant, reliable, and presented in accordance with court rules. In the case of expert evidence, it must also meet the standards set out in CPR Part 35, including transparency and independence.
The expert’s role is to assist the court by providing objective, technical insight. This includes preparing a report, answering questions from legal representatives, and, if required, giving evidence under cross examination.
Yes. Expert witnesses may be cross examined in court to test their findings, methodology, and conclusions. This is why clarity, consistency, and full compliance with Part 35 are essential.
A compliant report typically includes instructions received, scope of work, methodology, evidence reviewed, analysis, conclusions, and a statement of truth. It must be clear, logical, and capable of being understood by non specialists such as judges or legal teams.
Independence ensures the report is credible and legally valid. The expert’s duty is to the court, not the client, meaning their conclusions must remain objective regardless of the outcome for the instructing party.
Yes. While primarily used in legal proceedings, Part 35 reports can also support disputes involving planning, enforcement, or land use where technical evidence is required. This may include matters linked to Local Planning Authorities via https://www.planningportal.co.uk/, particularly where environmental or site condition issues are contested.
An expert report should not include biased opinions, unsupported assumptions, or advocacy for a particular party. It must remain factual, evidence based, and professionally objective at all times.
