Although Marshall agreed that a formal hearing was not required, he did believe that fairness required the Board to notify the inmates sufficiently far in advance to allow them to prepare their cases and retain counsel if they so desire. Marshall also believed that fundamental fairness required the Board to state the evidence on which it had relied in denying parole. This requirement would focus the Board more carefully on the statutory criteria and promote a more careful consideration of the evidence, while at the same time affording the inmates to contest factual inaccuracies in the record. The marginal increased burden on the Board was slight in comparison to the increased fairness these features would provide.
