CONSTITUTIONAL LAW AND ADMINISTRATIVE LAW IN INDIA

India has a written Constitution which is the grundorm of the legal system in country. It conditions and overrides all legislative and administrative action. The fact, however, remains that administrative law has become today sui juris and is recognised as a separate, independent branch of the legal discipline though at times constitutional law and administrative law may overlap.
As regards the relationship between constitutional law and administrative law, the correct position may be said to be that if one draws two circles of administrative law and constitutional law, at a certain place they may overlap and this area may be characterised as the ‘watershed’ in administrative law.’

As regards Indian position, one can include in the watershed the whole system of control mechanism which has been embodied in the Constitution for the control of the actions of administrative authorities i.e. Articles 32, 226, 136, 227, 300 and 311.
Moreover, in the area of watershed may also come those administrative agencies which are provided for by the Constitution itself e.g.,

Moreover, the constitutional limitations on delegation of powers to the administrative authorities and constitutional provisions relating to Fundamental Rights which impose fetters on administrative action are also included in the watershed.
