Article 11 is closely related to Article 8(2), which requires proscription against being held in ‘servitude’. That term comprises two practices of relevance: debt bondage, typically associated with feudal systems of slave labour, but also found in various contemporary forms of exploitation; and bonded labour, which still survives within the traditional practices of certain countries. Among the differences between Articles 8 and 11 is that Article 11 precludes imprisonment as a consequence of inability to fulfil a contractual obligation, whereas servitude within Article 8 typically concerns exploitation for commercial gain devoid of any contractual background.
