Public interest law encompasses a wide range of legal work that is aimed at promoting the public good and protecting the rights of all citizens. It includes representing individuals and organizations that cannot afford legal representation, advocating for changes in laws and policies that benefit the public, and challenging government actions that violate the law.

Public interest lawyers often face a number of challenges, including limited funding and resources, hostility from government agencies and corporations, and lack of public awareness and support. These challenges can make it difficult for public interest lawyers to effectively advocate for their clients and promote the public good.

Public interest law plays a vital role in promoting social justice by helping to ensure that everyone has equal access to justice, challenging laws and policies that discriminate against marginalized groups, and advocating for policies that promote economic and social equality.

Brown v. Board of Education (1954) was a landmark case in which the Supreme Court ruled that racial segregation in public schools was unconstitutional. Obergefell v. Hodges (2015) was a landmark case in which the Supreme Court ruled that same-sex couples have the right to marry.

Individuals can support public interest law by donating to public interest law organizations, volunteering with public interest law organizations, and contacting their elected officials to advocate for public interest law funding.
