In 2002, the
United Nations High Commission for Refugees (UNHCR) published updated guidance for the interpretation of the PSG category.
Broad guidelines • The PSG category is not meant to be used as a catch-all, and a PSG cannot be defined
exclusively based on persecution. In other words, just the fact that a person is persecuted does not make the person a member of a PSG. • There is no
closed list of PSGs. Rather, membership in a PSG should evolve over time, based on the diverse and changing nature of different groups and evolving international human rights norms. • The Convention grounds are not mutually exclusive. A person may claim refugee status based on membership in a PSG as well as the other grounds such as religion or political opinion, if they apply.
Two approaches: protected characteristics (immutability) and social perception The UNHCR document identified two approaches have been used to determine membership in and legitimacy of PSGs: • The
protected characteristics (or
immutability) approach: This approach examines whether a group is united by one of these: • An innate
immutable characteristic (such as sex or ethnicity) • An immutable characteristic that is not innate but is unalterable for other reasons (such as the historical fact of a past association, occupation, or status) • A characteristic that is so fundamental to human dignity that a person should not be required to change it. • The
social perception approach: This approach examines whether or not the group shares a common characteristic which makes them a cognizable group or sets them apart from the society at large. The UNHCR document provides the following guidance regarding the interpretation of the protected characteristic approach: A particular social group is a group of persons who share a common characteristic other than their risk of being persecuted, or who are perceived as a group by society. The characteristic will often be one which is innate, unchangeable, or which is otherwise fundamental to identity, conscience or the exercise of one’s human rights.
Additional observations The UNHCR document offered the following additional guidelines regarding PSG membership: • Persecution cannot alone be used to define PSG status, but it can be part of the social perception case for PSG status, i.e., the fact that people having a characteristic are persecuted is evidence that that characteristic is socially perceived as making them a distinct group. • The PSG need not be cohesive, i.e., the members may not know one another or be coordinating towards any common goal. • Not all members of the PSG need be persecuted. The document notes that members of the group may not be at risk if, for example, they hide their shared characteristic, they are not known to the persecutors, or they cooperate with the persecutor. • The size of a PSG should not be a relevant consideration. PSGs can range from small minorities to groups such as "women" (who constitute about half the population). • Persecution by non-state actors is relevant if either the persecution itself is targeted based on membership in the PSG,
or the state's unwillingness to help the victim of persecution is due to the victim's membership in the PSG. == United States ==
