By and large, these cases are the doctrinal progeny of
Linkletter insofar as they adhere to its threefold test for retroactivity. They diverge considerably, however, on the date which they set for a retroactive limit.
Tehan followed
Linkletter in requiring that the rule with which it dealt applied to all cases on direct review at the time the rule came down.
Johnson went on to hold that
Miranda and
Escobedo were effective in all cases which went to trial after their respective dates of decision.
Stovall then moved the date forward farther still, holding
Wade and
Gilbert applicable to cases which involved confrontations occurring after their date of decision, a result followed in
Desist, Williams, Adams and, in part,
DeStefano. Two aberrations occurred in the interim separating
Stovall from
Adams; Fuller held that the exclusionary rule
of Lee v. Florida, 392 U.S. 378, 88 S.Ct. 2096, 20 L.Ed.2d 1166 (1968) — based on deterring violations of section 605 of the Federal Communications Act of 1934, 47 U.S.C. § 605, rather than the Fourth Amendment — was to apply only to trials in which tainted evidence was sought to be introduced after
Lee, while
DeStefano appeared to apply the cutoff date of
Johnson in holding that Duncan v. Louisiana, 391 U.S. 145, 88 S.Ct. 1444, 20 L.Ed.2d 491 (1968), which arguably required unanimous verdicts in criminal eases, applied only to trials which began after its date of decision, rather than to cases where a jury was charged thereafter. The reasons for these aberrations are not at all clear, nor is the reasoning which supports the date approved in
Johnson. See Schwartz, Retroactivity, Reliability, and Due Process, 33 U.Chi.L.Rev. 719, 763 (1966) ; Mishkin, Foreword: The High Court, the Great Writ, and the Due Process of Time and Law, 79 Harv.L.Rev. 56 (1965) ; The Supreme Court 1965 Term, 80 Harv.L.Rev. 91, 140-41 (1966). In any event, it is clear that appellees carry a two-fold burden on their contention that
Miller should be prospectively applied. They must show that
Miller is like
Mapp and that the advanced date approved in
Stovall, not
Johnson, is the one from which prospectivity should be measured, since the trial in this case has not yet taken place. We need not reach the second of these questions if appellees cannot prevail on the first.
