Neelima Vanguri was named The Legal’s 2018 Attorney of the Year on Wednesday night at a celebratory event in Philadelphia, honored for her pioneering work on the transgender rights case Blatt v. Cabela’s Retail.

In Blatt, Vanguri became the first attorney in the country to argue that a company can violate the Americans with Disabilities Act by denying a transgender person use of a bathroom that corresponds with the gender they identify with. Vanguri successfully convinced the U.S. District Court for the Eastern District of Pennsylvania that her client, Kate Lynn Blatt, a transgender employee of outdoor retailer Cabela’s, should be allowed to move forward with a claim of Americans with Disabilities Act discrimination based on the condition of gender dysphoria. The case eventually settled, cementing the district court’s ruling that gender dysphoria is a debilitating condition that is covered under the ADA.
