Tornetta’s lawyers argued the Tesla board had a duty to offer a smaller pay package or look for another CEO and they should have required Musk to work full-time at Tesla instead of allowing him to focus on other projects, like running Twitter.

Tornetta wants some or all of the package to be rescinded.

Musk, who founded rocket company SpaceX, admitted during his testimony that his pay package provided funds he would use to finance interplanetary travel.

“It’s a way to get humanity to Mars,” he testified. “So Tesla can assist in potentially achieving that.”

His lawyers also argued the pay plan benefited shareholders by increasing the value of their stock 10 times.

Chancellor Kathaleen McCormick of Delaware’s Court of Chancery must determine if the Musk, who owned 22 percent of Tesla stock in 2018, controlled the company through board ties and his personality, which will shape the outcome of the case.
