5. Administrative functions: The judges perform certain executive functions. Appointments of officers and secants, maintenance of records, administration of staff etc. are performed by the judiciary. Superintendence over lower courts is another function of the judiciary.
6. Advisory function: The highest court of the country sometimes gives advices to the executive and the legislature on constitutional points, if sought for. Thus the Judiciary has advisory functions too. If it appears that a question of law or fact has arisen, it may be referred to the judiciary for its advice.
7. Protection of fundamental rights: The Judiciary acts as a protector of rights of the citizens guaranteed by the law of the land and the constitution. The court can declare any law which transgresses a fundamental right as invalid. In India the judiciary has the power to issue writs in the name of habeas corpus, prohibition, mandamus, quo warranto and certiorari.
8. Guardian of the constitution: The Judiciary is regarded as the guardian of the constitution. In federal States this function is discharged by the application of the power of judicial review. The Supreme Court of India enjoys limited power of judicial review in invalidating laws made by Parliament or State Legislatures.
Importance of the Judiciary: The importance of the judiciary in a democratic society can hardly be exaggerated. Judiciary is a part of the democratic process. Judiciary not only administers justice, it protects the rights of the citizens and it acts as the interpreter and guardian of the constitution. In many states the judiciary enjoys the power of judicial review by virtue of which the judiciary decides the constitutional validity of the laws enacted or of the decree issued. It can invalidate such laws and decrees which are not constitutional.
