Law’s certainty depends directly on its predictability, in the sense both of the predictability that consequences predetermined by norms will occur and of the predictability that the predetermined consequences will not occur. The existence of a right is independent of the existence of guarantees, which is, on the contrary, one of the conditions of its certainty, in the sense that its factual effectiveness is predictable. Nevertheless, secondary guarantees in particular can also be ineffective and, as a consequence, formally guaranteed law can become ineffective. The ineffectiveness of secondary guarantees may be caused by a variety of factors: government policies, the policies practised by governance agencies or cultural circumstances (the "case of the anti-Antigone"). This last area, in particular, takes the form of inertia on the part of the owners of guaranteed right, who fail to activate the guarantees provided for protecting certain rights.
