As of my last update in September 2021, there are 11 fundamental duties of Indian citizens mentioned in the Indian Constitution. These duties were added by the 42nd Amendment Act in 1976. However, it's important to verify with up-to-date legal sources because constitutional amendments can occur, potentially changing the number or content of these duties after my last update.

Dr. B.R. Ambedkar described the right to constitutional remedies (Article 32) as the "heart and soul" of the Constitution. This right provides Indian citizens the freedom to approach the Supreme Court, the highest judicial body in the country, for the protection of their fundamental rights. It grants citizens the freedom to seek legal remedies when their fundamental rights are violated.

Governments are classified as unitary or federal based on the distribution of power between the central and regional authorities. In a unitary system, all power is concentrated in the central government. In federal systems, power is shared between central and regional governments, each having distinct spheres of authority.
