Under certain circumstances, a unilateral declaration of a State may give rise to legally binding obligations onto the declaring State.[1] The binding character of such a declaration is based on the principle of good faith.[2]
States regularly resort to unilateral declarations in the cyber context, including declarations on the possible content of confidence-building measures for cyber space,[3] declarations of disapproval regarding specific cyber behaviour by other States,[4] declarations regarding the attribution of specific cyber attacks, and national position papers on cyber space. [5] It is, however, doubtful that these declarations fulfil the criteria for binding unilateral declarations.
For a unilateral declaration to be legally binding, the following criteria must be met:
The declaration must be made publicly.[6] It may be expressed either in oral or written form.[7] The declaration may be addressed to a specific subject of international law, i.e., a State, or to the international community as a whole.[8]
The declaration must express the will of the declaring State to be bound by the declaration.[9] To determine whether a declaration is binding, its content, all the factual circumstances in which it was made, and the reactions to which it gave rise must be considered.[10]
The declaring state organ must be authorized to make the according declaration,[11]as is presumed for heads of State, heads of Government, and ministers for foreign affairs.[12]
The content of the declaration must be sufficiently clear and specific.[13] The obligations themselves must be interpreted primarily considering the text together with the context and the circumstances in which it was formulated.[14] In case of doubt, a restrictive interpretation should be chosen.[15]
