Ann Al-Bahish litigates environmental and commercial matters across the country and has tried cases in both state and federal courts, before juries and judges. Her clients have included railroads, energy companies, manufacturers, healthcare entities, and state governments, among others.
As an attorney with a Ph.D., Ann is highly adept in presenting and analyzing expert testimony and evidence, including scientific and economic evidence essential to liability and damages findings in civil cases. Ann successfully represented a major energy company in a five-week jury trial of environmental contamination claims. Plaintiffs claimed personal injury and property damage from an alleged neighborhood cluster of asthma, lupus and autoimmune diseases. Plaintiffs’ counsel sought multi-million dollar damages, including punitive damages. The jury returned a verdict for the company on all claims.
In 2018 Ann tried and obtained a complete defense judgment on a $90 million environmental allocation claim brought against her client in federal district court in Tacoma, Washington. She tried an environmental indemnity dispute before a jury in 2017, striking all claims for profits and achieving damage reductions for her client.
Ann has led trial teams and has tried cases in Delaware, New Mexico, Texas and Washington and has additional litigation and appellate experience in California, New Jersey, New York, and Oregon and Vermont. She has tried, litigated and resolved environmental cost recovery claims under CERCLA and state analogs and has also handled other complex litigation including natural resource damages claims and products liability, personal injury, and property damages cases.
Because of her public health background, Ann has also advised clients on emerging legal issues related to medical technology and medical or consumer products. She has also handled emergency response matters that require dispute resolution and/or legal, safety, health and risk communication with multiple stakeholders. Ann has published and spoke on diverse environmental and health topics.
Using her litigation abilities, Ann also has helped her clients prevent and/or mitigate losses and disputes through the negotiation and creation of clear, cohesive documents that aid and promote successful business relationships and allocate risk. Ann strives to responsively provide practical, creative and useful legal advice, and believes in investing her own time to better learn and understand the needs of her clients.
Clients appreciate that Ann not only offers them consistently on-point advice, but that she is also easy to work with, responsive, flexible and down-to-earth, and delivers continually meticulous attention to detail. Ann is dedicated to understanding what her clients need, and then effectively developing the case around those goals.
