Constitutional flexibility refers to the ability of a constitution to adapt to changing circumstances and societal needs. This can occur through formal amendments or informal practices that allow for interpretation and application of constitutional principles over time. Such flexibility helps ensure that a constitution remains relevant and effective in governing a nation. In many countries, including the United States, constitutional flexibility is achieved through mechanisms like judicial review, where courts interpret laws and the constitution itself. This process allows for adjustments in legal frameworks without the need for a complete overhaul, promoting stability while accommodating progress and change.
