In Olga Tellis vs. Bombay Municipal Corporation case, the judges said that the Right to Livelihood was part of the Right to Life. They stated that life does not merely imply an animal existence; it cannot be lived without a means of living, that is, "the means of livelihood". In the case of Olga Tellis vs Bombay Municipal Corporation, the people live in slum. They have small jobs in the city and for them there is nowhere else to live. The eviction of their slum will lead to deprivation of their livelihood and consequently to the deprivation of life.
Thus, it can be said that Right to Life means the need of basic requirements of livelihood i.e., food, shelter and cloth.
