Public interest law is defined broadly to include all legal work which serves underrepresented people or causes, or which attempts to positively affect society at large. This includes traditional public interest work, such as legal services for the poor, organizations that protect the constitutional rights of traditionally underserved people, and public defenders. Public interest work also includes pro bono work at law firms. It includes jobs in all domestic and international employment fields. Private sector and public interest jobs differ less in their practice areas than in their philosophical orientations.
Public interest law offers diverse and exciting practices, and public interest lawyers are found all across the nation and throughout the world. In Wyoming, public interest work includes working for the public defender's office, for Legal Aid, working in a non-profit conservation organization, working for the Legal Services Clinic, the Domestic Violence Program or Defender Aid. The work of public interest lawyers encompasses a broad spectrum of lawyering activities.
