16 U.S.C. § 410f — Limitation of Federal action during reservation period

This section limits what the federal government can do to landowners who kept a "reservation" right under subsection (1) of section 410e of this title. A reservation right lets certain owners keep some interest in their land — such as a lease — even after the government has otherwise acquired the property. As long as an owner's reservation period is still running, the federal government cannot take a series of specific actions regarding any lease that applies to that owner's land: it cannot purchase the lease, acquire it some other way, terminate it, or otherwise interfere with it. The only way the federal government can take any of these actions during the reservation period is if the owner consents. In other words, this section protects the owner's control over their retained lease rights against unwanted federal interference for as long as the reservation lasts.
