James Rudisill served during periods that made him eligible for benefits under both the Montgomery and Post-9/11 GI Bills. After using part of his Montgomery benefits, he sought to use Post-9/11 benefits for graduate education. The Department of Veterans Affairs applied a coordination provision that would have limited his additional benefits to the unused portion of his earlier entitlement. The Supreme Court of the United States held that the statute permitted Rudisill to receive the separate Post-9/11 entitlement, subject to the overall statutory cap, because the coordination provision did not reduce benefits earned through distinct qualifying periods of service in this circumstance. The Court reversed the Federal Circuit and remanded. Separate opinions questioned the development and use of a veteran-favoring interpretive canon, and one dissent would have enforced the statutory coordination mechanism as written.
