In J. L. v. Latvia (2012), the European Court of Human Rights found that Latvia had failed to comply with its obligation under Article 3 of the European Convention on Human Rights to carry out an effective investigation into allegations of ill-treatment, because it had failed to properly investigate a prisoner's allegations of rape and assault by fellow inmates, who sought revenge against the victim due to his co-operation with the police.
Letonia (2012), a condamnat Letonia pentru că nu a respectat obligația prevăzută in articolul 3 din Convenția Europeană a Drepturilor Omului de a efectua o investigație corecta a acuzațiilor de viol împotriva unui deținut, care fusese abuzat de alți deținuți drept pedeapsă pentru cooperarea cu poliția.
