Law is primarily perceived by most people to be a set of rules promulgated by a legitimate authority (such as parliament, city council, administrative councils or international body) designed to regulate societal, group or state behavior. As such is it usually seen to be simply prescriptive in identifying what kinds of acts are not allowed, thereby legalizing all other actions. Although there are laws that lay out affirmative duties (such as a duty to care for a child who belongs to one’s family, the duty of nations to collaborate to achieve some human rights objectives), the vast majority of laws are prohibitory in nature and seek to limit individual or group conduct. What is not forbidden is therefore implicitly allowed. If law is a system of enforceable rules governing social relations and legislated by a political system, it might seem obvious that law is connected to ideology. Ideology refers, in a general sense, to a system of political ideas, and law and politics seem inextricably intertwined. Just as ideologies are dotted across the political spectrum, so too are legal systems.
