distinction The distinction is also between civilian objects
and military objectives.
It is necessary to differentiate between:
➔weapons that are employed in specific

circumstances contrary to the principle of
distinction, killing combatants and civilians
indiscriminately
➔ weapons that by their very nature or design
cannot possibly maintain the distinction in any
set of circumstances.

suffering In the words of the ICJ, it is prohibited to employ

weapons “uselessly aggravating’ the suffering of
combatants, the test being ‘a harm greater than that
unavoidable to achieve legitimate military objectives”.
In essence, the injunction against ‘superfluous injury or

unnecessary suffering’ hangs on a determination whether
injury/suffering is avoidable or unavoidable.

employment of ‘weapons calculated to cause

certain weapons may impose restrictions.
Restrictions exclude use in specified
conditions, without ruling out resort to the
same weapon on other occasions.
Weapons subject by treaty to prohibition or
restriction of use can be divided into two
wide-ranging categories:
● conventional weapons
● weapons of mass destruction.

There are a number of treaties prohibiting the

deployment of nuclear weapons in designated
areas (such as Antarctica, outer space and the
seabed), their testing, and even their
possession by certain countries; establishing
nuclear free zones; and creating
non-proliferation obligation.
ICJ’s manner of speaking strongly suggests a

non liquet, since the Advisory Opinion could
not conclude definitively whether the disputed
action is lawful or unlawful.
The accepted definition of an autonomous weapon system is:
“A weapon system that, once activated, can select and engage
Autonomous targets without further intervention by a human operator.”
weapons There are three categories of such devices:
● ‘Man-in-the-loop’, in which a human being pilots the

device by remote control. This weapon system is not
autonomous.
● ‘Man-on-the-loop’, where the machine can select and
engage targets, without additional human input
subsequent to activation, but a human operator
monitoring it can intervene. This weapon system is
semi-autonomous.
● ‘Man-out-of-the-loop’, where the system acts entirely on
its own there being no override capability reserved for
human review. This ‘fire-and-forget’ mechanism is truly
autonomous.

new weapons The sheer novelty of a weapon does not
necessarily present an insurmountable challenge
to existing LOIAC. To the contrary, LOIAC
principles show a remarkable capability of
bringing new weapons within their fold. Besides,
rather than testing the limits of these principles,
new weapons may actually facilitate their
application by enabling, e.g., a greater degree of
accuracy in targeting.
LOIAC trumps scientific and technological
developments. If a new weapon is prohibited ab
initio, its introduction into the arsenal must be
aborted. Sometimes, a significant upgrading of an
existing (lawful) weapon will also cause it to
become unlawful in its new incarnation.
