This decision laid down the following propositions : (i) whether the principles laid down in an impugned Act take into account all the elements to make up the true value of the property and exclude matters which are to be included is a justiciable issue; (ii) that the law fixing compensation or laying down princi ples governing its fixation cannot be questioned on the ground of inadequacy; (iii)that the connotation of "compensation" and the question of justiciability are distinct concepts and should be kept apart while considering the validity of the impugned provision; (iv) that the fact that the amended Article uses the same words, viz., "compensation" and "principles" shows that Parliament used them in the sense in which they were construed by this Court, and (v) that the legislature must provide for a just equivalent or lay down principles fixing such just equivalent and if that is done, such a law cannot be questioned on the ground of inadequacy of compensation.
