A constitutional right is different from fundamental rights enshrined in part III of the Indian Constitution. The Supreme Court pointed out the difference between a legal right and a fundamental right in number of cases. Some significant differences are:-
(a) A legal right is the offshoot of the ordinary law framed by the legislature, whereas fundamental rights are continued in the condition and are of a transcendental character. These are protected against any violation of any authority.
(b) A Fundamental right cannot be waived, whereas there are instances where a legal right has been violated.
(c) An ordinary legal right can be taken away by the state whereas the fundamental rights are placed beyond the reach of the state except as provided by the constitution
