Legal certainty refers to the principle that laws should be clear, publicized, and stable, allowing individuals and businesses to understand their rights and obligations. This clarity helps prevent arbitrary decisions by authorities and promotes trust in the legal system. When laws are predictable, people can make informed choices and plan for the future. Additionally, legal certainty supports the rule of law, ensuring that everyone is treated equally under the same set of laws. It is essential for fostering a stable environment for businesses, encouraging investment, and protecting individual rights. Without legal certainty, the legal system can become chaotic and unpredictable.
