A purely ceremonial and even ornamental role is given to the Head of State if the bill becomes a law whether or not he or she signs the bill as envisaged in the constitution. Hence, the act is not legal prerequisite to enact a law. In other constitutions, the president’s action is an essential part of the process but he or she is directed to sign. Similarly, many constitutions require the president or king to sign without using an affirmative language. In all of these examples, the Head of State is expected not to interfere.
