An amicus curiae (literally, 'friend of the court') is a person or organisation that is not a party in a case before court, but is allowed to intervene in a case and make legal or factual submissions. For an amicus to be admitted, the submissions made must be relevant to the proceedings and introduce information or arguments that are different to those raised by the parties, and which are useful to the Court. An amicus usually makes written submissions, but can also be allowed by the court to present oral argument to the court. CLC has intervened as amicus curiae in three cases in which key issues relating to the enforcement of socio-economic rights were involved.
