Our Firm

“It is impossible to overstate the commitment of Arnold & Porter in the fight for racial equity and for equal justice. The firm’s dedication to ensuring the law is used in the services of good is built in its DNA…We are proud to partner with a firm that treats its pro bono clients with the same dignity, respect, and urgency as those who pay a fee.” - Jonathan M. Smith, Washington Lawyer’s Committee for Civil Rights and Urban Affairs

What Pro Bono Means to Us

Pro bono is key to who we are and the reason many of our attorneys make Arnold & Porter their professional home. Our attorneys provided more than 130,000 hours of pro bono work during 2022. From our early days defending the rights of those persecuted during the McCarthy hearings and arguing for a right to counsel in Gideon v. Wainwright, to securing the right to vote in recent elections, we are driven to provide equal access to justice.

We have a long history of taking on matters to redress injustice, before courts and administrative tribunals (including the U.S. Supreme Court), before legislative and regulatory bodies, and in support of nonprofits. Our lawyers around the globe deliver extensive pro bono services that include cutting-edge impact litigation aimed at systemic change, individual representation for people who cannot otherwise afford counsel, regulatory and public policy advocacy, and nonprofit counseling.

The broad spectrum of pro bono work we undertake is driven by our dedication to amplifying the voices of those who might not otherwise be heard.
