1. All the administrative actions are not subject to judicial control. There is much kind of administrative actions which according to the constitution cannot be reviewed by the law courts. There is also a tendency on the part of the legislature to exclude by law certain administrative acts from the judiciary.
2. Even in those administrative actions which are within its jurisdiction, the judiciary cannot by itself take cognizance of excesses on the part of officials. It can intervene only on the request of somebody who has been affected or is likely to be affected by an official action.
3. The judicial process is very slow and cumbersome. The courts follow certain set of technical pattern of procedure beyond the comprehension of a layman and then the procedure is so long that it cannot be known as to when the final judgement shall be given. There have been cases which are pending with the courts for years together.
4. Sometimes the remedies offered by the law courts are inadequate and ineffective. In many cases, especially relating to business activities, mere announcement of an administrative action may cause an injury to the individual against which not even a suit can be filed in the law Court.
5. The government may deprive the person of the remedy granted to him by the court by changing the law or rules thereof.
6. Judicial action is incredibly expensive and cannot therefore be taken advantage of by many people. Filling a suit means paying the court fee, fee of the lawyer engaged and cost of producing witness etc., which only few can afford.
7. The highly technical nature of most of the administrative actions saps the force of judicial review. That is why the modern trend is towards the establishment of Administrative Tribunals which consist of persons experts in technical matters.
