Answer:
The president has to sign it.
Step-by-step explanation:
In the last phase of the legislative process, draft laws will be forwarded to the President of the Republic for sanction or veto.
The sanction shall express the agreement of the President with the content of the bill approved by the Legislature. The veto, on the contrary, will demonstrate its opposition, total or partial, to the text of the proposition, which can not be transformed into a law unless the veto is rejected by the National Congress.
