Legal exceptions refer to specific circumstances where the general rules of law do not apply. These exceptions allow for flexibility in the legal system, enabling courts to make decisions that consider unique situations. For example, in cases of self-defense, individuals may be legally justified in using force even if it typically would be considered unlawful. Another common legal exception is the doctrine of necessity, which permits actions that would otherwise be illegal if they are taken to prevent a greater harm. These exceptions help ensure that the law can adapt to various scenarios while still maintaining justice and fairness.
