In convention 182, the International Labor Organization defines what it calls the "worst forms of child labour". The Harkin-Engel protocol specified a deadline in 2005, to eliminate these from cocoa production. Because the cocoa industry did not meet this deadline, a lawsuit was filed against Nestlé and others on behalf of three Malian children. The suit alleged the children were trafficked to the Ivory Coast, forced into slavery, and were frequently beaten on a cocoa plantation.
