Presidential Veto Powers

A presidential veto is a constitutional rule that enables a president (or elected head of state who might, in some cases, go by another title) to refuse assent to a bill that has been passed by the legislature, and thereby to stop the bill from becoming law. The grounds on which the veto power may be exercised and the difficulty of overturning the veto vary between jurisdictions.

International IDEA’s Constitution-Building Primers are designed to assist in-country constitution-building or constitutional-reform processes by helping citizens, political parties, civil society organizations, public officials and members of constituent assemblies make wise constitutional choices. They also provide guidance for staff of intergovernmental organizations and other external actors working to provide well informed, context-relevant support to local decision-makers.

Each Primer is written as an introduction for non-specialist readers, and as a convenient aide-memoire for those with prior knowledge of, or experience with, constitution-building. Arranged thematically around the practical choices faced by constitution-builders, the Primers aim to explain complex constitutional issues in a quick and easy way.
