36 MEDVEDYEV AND OTHERS v. FRANCE JUDGMENT of law; and the importance of the promptness or speediness of the requisite judicial controls under Article 5 §§ 3 and 4 (see McKay, cited above, § 30). 118. The Court also notes the importance of the guarantees afforded by Article 5 § 3 to an arrested person. The purpose of this provision is to ensure that arrested persons are physically brought before a judicial officer promptly. Such automatic expedited judicial scrutiny provides an important measure of protection against arbitrary behaviour, incommunicado detention and ill-treatment (see, among other authorities, Brogan and Others, cited above, § 58; Brannigan and McBride v. the United Kingdom, 26 May 1993, §§ 62-63, Series A no. 258-B; Aquilina v. Malta [GC], no. 25642/94, § 49, ECHR 1999-III; Dikme v. Turkey, no. 20869/92, § 66, ECHR 2000-VIII; and Öcalan, cited above, § 103). 119. Article 5 § 3, as part of this framework of guarantees, is structurally concerned with two separate matters: the early stages following an arrest, when an individual is taken into the power of the authorities, and the period pending any trial before a criminal court, during which the suspect may be detained or released with or without conditions. These two limbs confer distinct rights and are not on their face logically or temporally linked (see T.W. v. Malta [GC], no. 25644/94, § 49, 29 April 1999). 120. Taking the initial stage under the first limb, which is the only one at issue here, the Court’s case-law establishes that there must be protection, through judicial control, of an individual arrested or detained on suspicion of having committed a criminal offence. Such control serves to provide effective safeguards against the risk of ill-treatment, which is at its greatest in this early stage of detention, and against the abuse of powers bestowed on law enforcement officers or other authorities for what should be narrowly restricted purposes and exercisable strictly in accordance with prescribed procedures. The judicial control must satisfy the following requirements (see McKay, cited above, § 32): (a) Promptness 121. The judicial control on the first appearance of an arrested individual must above all be prompt, to allow detection of any ill-treatment and to keep to a minimum any unjustified interference with individual liberty. The strict time constraint imposed by this requirement leaves little flexibility in interpretation, otherwise there would be a serious weakening of a procedural guarantee to the detriment of the individual and the risk of impairing the very essence of the right protected by this provision (see Brogan and Others, cited above, § 62, where periods of four days and six hours in detention without appearance before a judge were held to be in violation of Article 5 § 3, even in the special context of terrorist investigations).
