More than 100 lawyers squeezed into a courtroom on Thursday in Boise, Idaho, to argue before a panel of seven judges about which U.S. courthouse should host the massive litigation over the Deepwater Horizon oil spill.

Heyburn II of the Western District of Kentucky, asked several times how the cases, which include personal injury and environmental claims, could be effectively divided into separate proceedings.
"The magnitude of this case may be such that it may dictate several judges working in tandem together," W. Mark Lanier of the Lanier Law Firm in Houston, told the panel.
Lawyers expected the panel to decide how to handle the cases before the end of August.

The cases are separate from an MDL over sudden, uncontrolled acceleration in Toyotas. U.S. District Judge Cormac Carney of the Central District of California some of the hybrid cases. Plaintiffs' attorneys argued that he should also get the rest.
