E/C.12/GC/17 page 7 Limitations 22. The right to the protection of the moral and material interests resulting from one’s scientific, literary and artistic productions is subject to limitations and must be balanced with the other rights recognized in the Covenant.16 However, limitations on the rights protected under article 15, paragraph 1 (c), must be determined by law in a manner compatible with the nature of these rights, must pursue a legitimate aim, and must be strictly necessary for the promotion of the general welfare in a democratic society, in accordance with article 4 of the Covenant. 23. Limitations must therefore be proportionate, meaning that the least restrictive measures must be adopted when several types of limitations may be imposed. Limitations must be compatible with the very nature of the rights protected in article 15, paragraph 1 (c), which lies in the protection of the personal link between the author and his/her creation and of the means which are necessary to enable authors to enjoy an adequate standard of living. 24. The imposition of limitations may, under certain circumstances, require compensatory measures, such as payment of adequate compensation17 for the use of scientific, literary or artistic productions in the public interest. III. STATES PARTIES’ OBLIGATIONS General legal obligations 25. While the Covenant provides for progressive realization and acknowledges constraints based on limits of available resources (art. 2, para. 1), it also imposes on States parties various obligations that are of an immediate effect, including core obligations. Steps taken to fulfil obligations must be deliberate, concrete and targeted towards the full realization of the right of everyone to benefit from the protection of the moral and material benefits resulting from any scientific, literary or artistic production of which he or she is the author.18 26. The progressive realization of that right over a period of time means that States parties have a specific and continuing obligation to move as expeditiously and effectively as possible towards the full realization of article 15, paragraph 1 (c).19 27. As in the case of all other rights contained in the Covenant, there is a strong presumption that retrogressive measures taken in relation to the right to the protection of the moral and material interests of authors are not permissible. If any deliberately retrogressive measures are taken, the State party has the burden of proving that they have been introduced after careful consideration of all alternatives and that they are duly justified in the light of the totality of the rights recognized in the Covenant.20 28. The right of everyone to benefit from the protection of the moral and material benefits resulting from any scientific, literary or artistic production of which he or she is the author, like all human rights, imposes three types or levels of obligations on States parties: the obligations to respect, protect and fulfil. The obligation to respect requires States parties to refrain from interfering directly or indirectly with the enjoyment of the right to benefit from the protection of the moral and material interests of the author. The obligation to protect requires States parties to
