# About Public Interest Experts

###### EXPERTS

 

## What is an expert?

"An expert witness is a person with specialized knowledge, skills, education, or experience in a particular field who is called upon to provide their expertise in legal proceedings to assist the court with understanding complex technical or scientific issues."([Cornell Law School](https://www.law.cornell.edu/wex/expert_witness))

An essential quality of an expert witness is the independence of their opinion. While experts are engaged by attorneys, their primary duty is to the integrity of their analysis and the ideas they present, ensuring their testimony remains impartial and unbiased.

In Litigation:  
An expert witness brings specialized knowledge to assist the court in understanding complex matters. They may provide testimony on issues ranging from economic damages and forensic accounting to technical or scientific complexities. Once accepted by the court as an Expert Witness, the expert's opinions are considered admissible evidence in the case, playing a crucial role in shaping the outcome of legal proceedings.

In Advocacy:  
Experts use their authority to analyze and promote specific ideas of public interest. Through white papers, op-eds, regulatory comments, and speaking engagements at conferences or before legislative bodies, they advocate for policies or concepts that shape public discourse and influence decision-making.
