 In 2001, the Irmas Project brought landmark litigation on behalf of tenants' rights group Inquilinos Unidos against one of the most notorious landlords in Los Angeles.The lawsuit was later joined by the Los Angeles City Attorney's office, and the law firm of Gibson, Dunn & Crutcher served as pro bono counsel on the suit.This case represented a landmark victory in the battle against landlords who subject their tenants to substandard health and safety conditions and set a significant precedent in the ability of tenants' groups to successfully prosecute owners attempting to hide behind a web of business identities.
