In the case of Berry et al., constituting the Board of Parole of Iowa, et al. v. Davis in 1916, the U.S Supreme Court dealt with issues related to parole and imprisonment. The petitioner, Davis was serving a life sentence for murder when he was paroled by the Governor of Iowa under a state law that allowed such action if it appeared "to be for the best interests of society." However, after being released on parole, Davis moved out-of-state without permission which resulted in his re-arrest and return to prison. He filed a writ of habeas corpus arguing that once paroled he could not legally be returned to prison unless convicted for another crime or violating conditions set forth at time of release - neither condition applied as moving out-of-state wasn't explicitly forbidden in his parole terms nor had he committed any new crimes. The Supreme Court ruled against him stating that while on parole an individual remains "in legal custody and under control" until their full term is served or they are pardoned; thus can be returned to prison if found necessary by authorities even without explicit violation terms stated at time of release.

In the dissenting opinion for Berry et al., Constituting The Board of Parole of Iowa, et al. v. Davis, it was argued that the majority's decision to uphold a law allowing life prisoners to be paroled after serving 20 years undermined the power and discretion of juries in determining appropriate sentences. It was contended that this ruling effectively allowed parole boards to alter jury-imposed sentences without any clear guidelines or standards, which could lead to arbitrary and inconsistent decisions about when a prisoner is ready for release. This lack of consistency would not only violate principles of fairness but also potentially endanger public safety by releasing dangerous criminals prematurely. Furthermore, it was suggested that such laws might discourage juries from imposing life sentences if they believed these could easily be reduced later on by parole boards.
