Constitutional rigidity refers to the difficulty of amending a constitution. In systems with high rigidity, changes require a complex process, often involving supermajority votes or approval from multiple governing bodies. This ensures stability and continuity in the legal framework but can also hinder necessary reforms. In contrast, constitutional flexibility allows for easier amendments, enabling governments to adapt to changing societal needs. While rigidity protects fundamental rights and principles, it may also lead to outdated laws that do not reflect current realities, creating a balance between stability and adaptability in governance.
