L.M. AND OTHERS v. RUSSIA JUDGMENT 31 above). The centre was staffed with medical professionals who provided the necessary care to the inmates, including the applicants (see paragraph 59 above). B. The Court’s assessment 131. The Court has previously found the conditions of detention at some Russian facilities for foreign nationals to be in breach of Article 3 guarantees. In doing so, the Court has had regard to constant overcrowding which was severe enough to justify, in its own right, the finding of a violation of Article 3 of the Convention, seen against the background of virtually non-existent outdoor exercise and deficient hygiene facilities (see Kim v. Russia, no. 44260/13, § 32, 17 July 2014). 132. In so far as the applicants complained about the material conditions, the Government presented a detailed description of the accommodation facilities, accompanied by relevant documents and other evidence. L.M. confirmed in his interview of 17 December 2014 that the material conditions of accommodation had not posed any particular problems in terms of overcrowding, personal space, hygiene and bathing facilities or access to regular outdoor exercise (see paragraph 52 above). M.A. did not make any specific submissions on that subject. 133. Having regard to the parties’ submissions, the Court is satisfied that the conditions of the applicants’ detention at the Kaluga detention centre corresponded to the description contained in the Government’s submissions (see paragraph 129 above). Taking into account the cumulative effect of those elements, it does not appear that the material conditions of the applicants’ detention could be regarded as inhuman or degrading. 134. In so far as the applicants complained of ill-treatment and verbal abuse by the centre guards, the Court notes that the information about two such incidents in August 2014 had been raised by L.M. and M.A. on 17 December 2014 during meetings with their representatives (see paragraphs 52 and 53 above). No further details are available; these statements are not corroborated by any other relevant evidence, such as complaints to the relevant authorities or medical evidence. 135. In so far as the applicants complained of a lack of medical treatment which could reach the threshold of treatment in breach of Article 3, the Court notes that the medical records submitted by the Government indicate that A.A. and L.M. had sought medical assistance on several occasions and that the administered treatment had led to an improvement in their conditions. No medical complaints were raised by the applicants in December 2014 or later. In fact, L.M. indicated that the detention centre had been staffed with four nurses who had administered treatment as needed (see paragraphs 52 and 59 above).
