What is the principle of legality?

The principle of legality is a legal principle that means that any exercise of a public power must be carried out in accordance with the current law and its jurisdiction, not according to the will or discretion of the people.

This implies that:

1. Clear and accessible laws: This avoids arbitrariness.
2. Respect for individual rights.
3. Protection against abuse of power or acting arbitrarily by the authorities.
4. Separation of powers: means that the legislative branch must be independent of the executive branch and the judicial branch.

Thus, this principle is essential to guarantee a rule of law in which all citizens can live under a clear and fair legal framework, which provides legal certainty and protects individual rights and freedoms, avoiding abuse of power and arbitrariness in the actions of the government and authorities.
