Abstract
In late June 2021, the Republic of Nauru invoked a legal provision known as the ‘two-year rule’ at the International Seabed Authority (ISA), which effectively obliges the Council of the ISA to complete the elaboration of the mineral exploitation regulations within the prescribed time of two years, that is, by 9 July 2023. This article provides an update on recent developments at the ISA since the invocation of the two-year rule, outlining six options that appear to be available to the ISA Council in response to the invocation of the rule.
