This contribution will engage with an aspect of the many issues of international humanitarian law (IHL) arising from the Indonesian invasion and occupation of East Timor, and 1999 retreat. It will rely for the factual assertions on the report of the East Timor Reception, Truth and Reconciliation Commission (CAVR), Comissão de Acolhimento, Verdade e Reconciliação de Timor Leste in Portuguese. This report is called Chega! (the exclamation mark is deliberate, and Chega! means ‘no more, stop, enough’). It contains the only detailed account of the intra-Timorese civil war of 1974–1975, followed by the invasion and occupation by, and eventual departure, of Indonesia from the one-time Portuguese non-self-governing territory. Certain limitations must be acknowledged. Important as it is, Chega! does suffer from the fact that Indonesia did not participate.
