Explanation:

Law is a system of rules that are created and enforced through social or governmental institutions to regulate behavior. It has been defined both as "the science of justice" and "the art of justice". Law regulates and ensures that individuals or a community adhere to the will of the state.
A court is any person or institution with authority to judge or adjudicate, often as a government institution, with the authority to adjudicate legal disputes between parties and carry out the administration of justice in civil, criminal, and administrative matters in accordance with the rule of law.
Mortality rate, or death rate, is a measure of the number of deaths in a particular population, scaled to the size of that population, per unit of time.
A judge is a person who presides over court proceedings, either alone or as a part of a panel of judges. The powers, functions, method of appointment, discipline, and training of judges vary widely across different jurisdictions. The judge is supposed to conduct the trial impartially and, typically, in an open court.
