ISSUE:
Whether Delhi has reached a higher pollution level, which is also affecting people's health?
Whether the existing environmental laws require the government to take measures to control air pollution in the interest of public health caused due to heavy vehicles?
RULE:
Article 21 of the constitution does not merely include the right to life and personal liberty. The right to life aspect of article 21 also encompasses a life more than a “mere animal existence” , therefore article 21 also provides for an inherent right to live in a clean and healthy environment.
