The adoption of article 64 of the ELAN law, in 2018, marks the end of the implementation of the principle of “accessibility for all to everything” established by the law of February 11, 2005. The deletion of this right from the texts is surprising, as this provision was hardly implemented. This article seeks to understand how a right dies. The right to accessibility was a moral and legal obligation that tolerated numerous derogations. Its abolition might have seemed unnecessary and costly. An analysis of the adoption of the Elan law highlights the specific conditions in which a right can disappear. Far from leading to only limited effectiveness, the successive derogations and simplifications have had an effect on written law by forging new categories of public action. We also show that the disappearance of the right to accessibility is linked to its competition with another right, the right of use.
