What duty does an expert have when giving evidence in court?

The proper duty of an expert when giving evidence in court is to assist the court. This obligation stems from the recognition that an expert's primary role is not to support any party's case, but rather to provide impartial, objective information that aids the court in understanding complex matters related to their expertise.

When experts testify, they are expected to present their findings and opinions based on their specialized knowledge, helping the judge or jury make informed decisions. This duty is foundational in ensuring that legal proceedings are fair and that judgments are made based on a comprehensive understanding of the evidence presented.

While experts may be hired by a particular party and can be paid for their services, their testimony must remain unbiased and focused on what is in the best interest of the judicial process. This principle helps preserve the integrity of the legal system and ensures that the expert's evidence is credible and reliable.
