Rights (hereinafter “the Inter-American Court”) has determined, “disrespect for human dignity cannot
137
serve as the bases for any State action.” 136
120.
Therefore, according to the jurisprudence of the Inter-American Court, while law
enforcement officials may legitimately use lethal force in the performance of their duties, this use must be
defined by exceptionality and must be planned and proportionally limited by the authorities so that “force
or coercive means may only be used once all other methods of control have been exhausted and have
138
failed.” In this sense, the use of force must be defined by its exceptionality and must be planned and
proportionally limited by the authorities. According to the Court, the use of lethal force and firearms
against persons by State security agents requires a higher degree of exceptionality, and must be
forbidden as a general rule. Its exceptional use must be determined by the law and restrictively construed
so that it is used to the minimum extent possible in all circumstances and never exceeds the use which is
139
“absolutely necessary” in relation to the force or threat to be repelled.
Whenever excessive force is
140
used, any resulting deprivation of life is arbitrary.
121.
In this regard, the IACHR has held that state agents may use lethal force “where strictly
unavoidable to protect themselves or other persons from imminent threat of death or serious injury, or to
141
otherwise maintain law and order where strictly necessary and proportionate.”
The use of force,
including lethal force, will only be lawful when nonviolent means are manifestly incapable of protecting the
142
threatened rights.
122.
For its part, the European Court of Human Rights (hereinafter “the European Court”) has
held that the term “absolutely necessary” in relation to the use of lethal force demands a test of necessity
that is stricter and more convincing than that used to determine whether State action is necessary in a
democratic society. As a result, any use of force must be strictly proportionate to the legitimate aim
pursued.143
123.
Therefore, when it is alleged that a death has occurred as a result of the excessive use of
force, the Inter-American Court has set out clear rules concerning the burden of proof. According to the
