Question

why is it essential to include into constitution ?​

Answer 1

Answer:

In providing fundamental rules about the source, transfer, accountability and use of political power in a society, a constitution introduces a separation between the permanent, enduring institutions of the state, on the one hand, and the incumbent government, on the other.

Answer 2

Answer:

Within states, a constitution defines the principles upon which the state is based, the procedure in which laws are made and by whom. Some constitutions, especially codified constitutions, also act as limiters of state power, by establishing lines which a state's rulers cannot cross, such as fundamental rights.
