Why do we need rights in a democracy and why the rights should be included in the Constitution?

(a) Rights are necessary in a democracy due to following factors:
(i) It is the basis of successful democracy because in a democracy, every citizen has to have the right to vote and the right to be elected to government. During elections it is necessary for every citizen that they should have the right to express their opinion, form political parties and take part in political activities.
(ii) Rights protect minorities from the oppression of majority. They ensure that the majority cannot do whatever it likes. They guarantee that the majority cannot take rights away the of minority particularly when the majority want to dominate the minority.
(b) The rights should be included in the Constitution to protect them from the arbitrary policies of the government because sometimes a government may go against the rights of their own citizens. So, rights should be placed higher than the government or included in the Constitution so that the government cannot violate these rights. For example in India, rights have been included in the constitution and cannot be taken-away in ordinary circumstances.
