Treaty flexibility unilaterally boosted: Reservations to European Social Charters

Thus far, research into reservations to treaties has often overlooked reservations formulated to both European Social Charters (and its Protocols) and the relevant European Committee of Social Rights practices. There are several pressing reasons to further explore this gap in existing literature. First, an analysis of practices within the European Social Charters (and Protocols) will provide a fuller picture of the reservations and responses of treaty bodies. Second, in the context of previous landmark events it is worth noting the practices of another human rights treaty monitoring body that is often omitted from analyses. Third, the very fact that the formulation of reservations to treaties gives parties such far-reaching flexibility to shape their contractual obligations (à la carte) is surprising. An important outcome of the research is the finding that, despite the far-reaching flexibility present in the treaties analysed, both the States Parties and the European Committee of Social Rights generally treat them as conventional treaties to which the general rules on reservations apply. Consequently, there is no basis for assuming that the mere fact of adopting the à la carte system in a treaty with no reservation clause implies a formal prohibition of reservations or otherwise discourages their formulation.
