The term "public interest" refers to the general well-being and welfare of society as a whole. It encompasses issues that affect people's lives, such as healthcare, education, economic development, environmental protection, and social justice. In legal contexts, public interest is often used to describe cases or causes that are considered important for the common good, and which may be taken up by lawyers or advocacy groups on behalf of a larger population. The concept of public interest is also relevant in government policies and decision-making processes, where it refers to actions that serve the best interests of citizens as a whole, rather than individual or special interest groups.
