Since its founding in 2003, Motley Rice has expanded its practice beyond traditional mass torts to cover areas including securities fraud, aviation and anti­terrorism. There’s one constant: a commitment to “causes, and not just cases,” said founding member Joseph Rice.

Rice has served as a lead settlement negotiator for plaintiffs with civil claims related to the 2010 Deepwater Horizon oil spill. In early September, Halliburton Energy Services Inc. agreed to a more than $1 billion settlement.
