Exploitation has been given a prominent place in the definition of ‘human trafficking’ found in the 2000 United Nations Palermo Protocol. It is identified as the specific aim of the crime of trafficking: all human trafficking is for the purpose of exploitation. But while the protocol lists some examples of exploitation, including slavery, servitude, or forced labour, it does not define the term itself. Nor do the numerous other international instruments that reference the term. And so, as Susan Marks has rightly wondered, we must ask ourselves: “When activists invoke international law to challenge exploitation, when lawyers advise on rights and duties regarding exploitation under international law, and when academics discuss the theme of exploitation in international legal writing, what is it that they have in mind?”
I recently proposed a tripartite definition of exploitation, which I argue underpins practices commonly referred to as ‘modern slavery’. While ‘modern slavery’ is not a legal category per se, I use it as an umbrella term for the practices of human trafficking, slavery, servitude, and forced or compulsory labour. These are jointly prohibited in many human rights instruments, either expressly, as in the EU Charter of Fundamental Rights or the Arab Charter on Human Rights, or implicitly, as in the case of the European Convention on Human Rights. Exploitation is a distinct harm that binds together practices captured by the human rights prohibition against ‘modern slavery’, which includes both actual manifestations of exploitation in the form of slavery, servitude, and forced or compulsory labour, and intended exploitation as part of human trafficking. The latter, if uninterrupted, always results in actual exploitation.
The three elements of my proposed definition are: “(a) abuse of vulnerability of an exploitee; (b) excessive (disproportionate) gain acquired through the actions of an exploitee; (c) sustained action (the practice takes place over a period of time)”. We will cover each element in turn below. Before we do that, however, I must first note that my proposed definition of exploitation applies only to practices of ‘modern slavery’ and represents the severity threshold for triggering important state obligations to protect victims under human rights law. Accordingly, while we may consider exploitation as a continuum, it is important to distinguish practices that trigger state obligations required by international human rights law from lesser forms of exploitation that warrant different types of action, or no action at all.
