Judicial system

The judiciary (also known as the judicial system or court system) is the system of courts that interprets and applies the law in the name of the state. The judiciary also provides a mechanism for the resolution of disputes. In some nations, under doctrines of separation of powers, the judiciary generally does not make law (which is the responsibility of the legislature) or enforce law (which is the responsibility of the executive), but rather interprets law and applies it to the facts of each case. In other nations, the judiciary can make law, known as Common Law, by setting precedent for other judges to follow, as opposed to Statutory Law made by the legislature. The Judiciary is often tasked with ensuring equal justice under law.

In many jurisdictions the judicial branch has the power to change laws through the process of judicial review. Courts with judicial review power, may annul the laws and rules of the state when it finds them incompatible with a higher norm, such as primary legislation, the provisions of the constitution or international law. Judges constitute a critical force for interpretation and implementation of a constitution, thus de facto in common law countries creating the body of constitutional law. For a people to establish and keep the 'Rule of Law' as the operative norm in social constructs great care must be taken in the election and/or appointment of unbiased and thoughtful legal scholars whose loyalty to an oath of office is without reproach. If law is to govern and find acceptance generally courts must exercise fidelity to justice which means affording those subject to its jurisdictional scope the greatest presumption of inherent cultural relevance within this framework.

In the US during recent decades the judiciary became active in economic issues related with economic rights established by constitution because "economics may provide insight into questions that bear on the proper legal interpretation". Since many countries with transitional political and economic systems continue treating their constitutions as abstract legal documents disengaged from the economic policy of the state, practice of judicial review of economic acts of executive and legislative branches have begun to grow.
