Three general methodologies have emerged in State practice.
58
Initially, the
scope of State immunity was determined on the basis of the so-called “purpose”
test. Pursuant to this view, immunity attached if the relevant act was performed for
a sovereign or governmental purpose. The vast majority of States have, however,
abandoned this position because of its overinclusiveness as all acts of States are
ultimately, directly or indirectly, for sovereign or public purposes.
The predominant position today is the “nature-of-the-act” approach,
59
pursuant
to which the decisive factor for the question of immunity is the nature, not the
purpose, of the particular act. If the act is by its nature a commercial or private-law
act, then it is
acta jure gestionis
, and it makes no difference whether that act serves some
sovereign or public purpose. While the “objective” nature-of-the-act criterion would
appear to be simple to apply, in practice it also tends to be underinclusive if strictly
construed. In common law countries, which do not readily distinguish between private
and public law, it additionally merely postpones the difficulty. Most importantly, the
nature-of-the-act approach fails to fully describe how courts actually adjudicate in hard
cases. Although the criterion works quite well in a strictly commercial context, States
seem to consider it much less satisfactory in other areas, including employment and
tort cases.
60
Consequently, a “context” approach has been articulated as an alternative,
demanding that the whole context of the State’s activity be considered. It takes the
position that an isolated characterization of an activity without regard to its meaning
is often misleading, and while the purpose may not be decisive (as it would turn
virtually every act of a commercial agent of the State into
acta jure imperii
), it may
clarify what was actually done.
61
The UN Convention in this respect represents a compromise designed to
accommodate the various State practices. Although it provides, in its Article 2(2)
that
“[i]n determining whether a contract or transaction is a ‘commercial transaction’ …
reference should be made primarily to the nature of the contract or transaction”
, it also
retains a (limited) role for the ‘purpose’:
“[P]urpose should also be taken into account if
the parties to the contract or transaction have so agreed, or if, in the practice of the State

In employment cases, it does not provide any scope for the recognition of sovereign activity. Crawford J.,
Brownlie’s Principles of Public International Law, 497. In tort cases, the distinction between
acta jure
gestionis
and
acta jure imperii
has proved to be largely irrelevant as the forum States interest in asserting
jurisdiction over the tort which has occurred within its territory prevails. Yang X., State Immunity in
International Law, 207-215.
