Public interest law is a legal practice that focuses on serving the interests of the public, particularly marginalized or disadvantaged groups. Lawyers in this field often work on issues such as civil rights, environmental protection, and access to justice. Their goal is to promote social change and ensure that everyone has equal access to legal resources. These attorneys may work for non-profit organizations, government agencies, or as private practitioners dedicated to public service. By addressing systemic issues and advocating for policy reforms, public interest lawyers play a crucial role in shaping laws and regulations that benefit society as a whole, including areas like civil rights and environmental law.
