The law really is not for those who are loaded with roses and lilly's. it is for the poores who had to do hard to earn for the meal for one time. The expansion of PIL is just commendable. Indian PIL is the extension of the American PIL but with wider wings and arms to give justice.
The relaxation of traditional locus standi rule is the strength of PIL movement. To be away from traditional adjudication needs both courage and strength. The above article is commendable in two different aspects. One, It is evolutionary in its content. And second, The justification of the Title. The whole reseach paper is the extension of the title. The features included above are exclusive and not inclusive hence the addition is invitable.
The use and abuse of the PIL is also taken into consideration by the author. But, I am a bit in disagreement with the author over the utility of the PIL. As per my view, I strongly recommend an Independent authority to do the job of PIL, instead to have regular bench hampering its work.
The features discussed by Praveen Dalal are worth quoting and discussing. To explain PIL in such a lucid way is very tough. congratualation to your site to have such a profound autor. Hoping aside you the same. The future of PIL will decide the course of Indian Welfare state.
