Marshall was involved in the struggle over the estate of J. Howard Marshall II, which included Stern v. Marshall, a case that reached the United States Supreme Court.
He was disinherited by his father, J. Howard Marshall II, after siding with William Koch in Koch's attempt to take over Koch Industries, Inc. from his brother, Charles Koch; Marshall II, who was a board member of the company, and his other son, E. Pierce Marshall, supported Charles.
