What is the importance of Article 19 to 22 of the Indian Constitution?

Articles 19 to 22 of the Indian Constitution deal with the different facets of the Fundamental Rights. These four articles form a charter of personal liberties, which provides the backbone of the chapter on Fundamental Rights. Of these, Article 19 is the most important and it may rightly be called the key-article embodying the “basic freedoms” under the Constitution, guaranteed to all citizens.
