One commonly adopted description of the contents of administrative                      law is that administrative law covers both substantive and                      procedural administrative law. This description limits the                      contents of administrative law to legislation. However, a                      review of academic works indicates that there is also another                      element - administrative law theory- which should be treated                      as an essential component of administrative law. 
Apart from administrative reconsideration and litigation,                      there are two more means currently available, under which                      the relevant parties may bring an action against administrative                      organs. These are part of procedural administrative law, laying                      down the legal procedures for those under administration to                      bring legal actions to challenge the activities of administrative                      organs. Another part of procedural administrative law includes                      legislation with which administrative organs must comply in                      undertaking administrative activities. 
With regards to the classification of the contents of administrative                      law, the broad approach holds that administrative law covers                      both substantive law and procedural law and has recently been                      adopted and widely accepted. The narrow approach maintains                      that administrative law should be restricted to procedural                      administrative law. 
Unlike what is generally accepted in common law jurisdictions,                      where administrative law is almost equivalent to judicial                      review, the concept of administrative law in China seems more                      adequate if the brad approach is adopted. It covers administrative                      law theory, and substantive and procedural administrative                      law.
