Alex Menson and Others against the United Kingdom (Application no 47916/99) (Decision)
A selection of key paragraph(s) can be found below the document.
Page 13-14: While there may be obstacles or difficulties which prevent progress in an investigation in a particular situation, a prompt response by the authorities in investigating a use of lethal force may generally be regarded as essential in maintaining public confidence in their adherence to the rule of law and in preventing any appearance of collusion in or tolerance of unlawful acts (see, for example, the Hugh Jordan judgment, cited above, §§ 108, 136-140).
Although there was no State involvement in the death of Michael Menson, the Court considers that the above-mentioned basic procedural requirements apply with equal force to the conduct of an investigation into a life-threatening attack on an individual regardless of whether or not death results. The Court would add that, where that attack is racially motivated, it is particularly important that the investigation is pursued with vigour and impartiality, having regard to the need to reassert continuously society’s condemnation of racism and to maintain the confidence of minorities in the ability of the authorities to protect them from the threat of racist violence.”
