Biography

Deirdre Marie-Iha is a civil litigator and appellate practitioner with Goodsill Anderson Quinn & Stifel. Her appellate experience is extensive spans more than 18 years in both federal and state court. She has argued numerous times before the Ninth Circuit Court of Appeals, the Hawai‘i Supreme Court, and the Intermediate Court of Appeals.  Deirdre has personally handled well over a hundred appellate proceedings, and over the years her caseload has generated more than 40 published opinions in the state and federal appellate courts.  Most recently her appellate work includes corporate governance, banking, other business matters, and trust litigation.  She also routinely handles complex civil matters in the trial courts, particularly business disputes and trust disputes. 

Before joining Goodsill, Deirdre practiced for 14 years as deputy attorney general at the Hawai‘i AG’s office, where she handled a number of high-profile, high-stakes matters, including the furloughs during the 2008-2009 financial crisis; the enactment and subsequent defense of the Marriage Equality Act in 2013-2015; and complex litigation regarding the State’s retiree health benefits.  She was also instrumental in the State’s challenge to the Muslim ban, Hawai’i v. Trump.

Deirdre has been practicing for more than 20 years. In 2003-2004, Deirdre clerked for the Honorable Corinne K. A. Watanabe, Associate Judge of the Hawaiʻi Intermediate Court of Appeals (now retired). Before that, Deirdre practiced in California. She graduated from the University of Colorado School of Law in 1999. Her undergraduate degree is in History, from Cornell University, where she graduated Phi Beta Kappa.

Deirdre is the 2021-2022 Chair of the HSBA Appellate Section, and is actively involved with the Appellate Pro Bono Program. The Appellate Pro Bono Program looks to match income-eligible pro se appellate litigants with attorneys willing to represent them pro bono in proceedings before the ICA and Hawaiʻi Supreme Court.

Deirdre is admitted to practice before all Hawai‘i state courts; the federal District Court for the District of Hawai’i; the Ninth Circuit Court of Appeals; and the United States Supreme Court.

OUTSIDE THE OFFICE

Deirdre enjoys family time with her husband and two sons. She is also a super-fan of the musical Hamilton – don’t ask her about it unless you are prepared to recite a line or two!
