The family of the slain peace activist Rachel Corrie is asking a federal appeals court to reinstate its lawsuit against Caterpillar Inc. Corrie was crushed to death beneath a 60-ton Caterpillar bulldozer as she tried to stop an Israeli soldier from demolishing a Palestinian home in the Gaza Strip in March 2003. The Corrie family’s suit says Caterpillar sold the Israeli government the bulldozers despite knowing they would be used for human rights abuses. Four Palestinian families with relatives killed or injured during Israeli home destructions have joined the Corries in the case. The suit was dismissed in 2005 after a district judge backed Caterpillar’s argument that it isn’t responsible for how the Israeli military uses its bulldozers.
