Below is an essay for our thir­ty-day series on John Paul Stevens by James Liebman, the Simon H. Rifkind Professor of Law at Columbia Law School. Liebman was a clerk for Justice Stevens dur­ing the 1978 Term and has since argued sev­er­al cap­i­tal and habeas cor­pus cas­es before the Supreme Court.

As he pre­pares to retire from the Supreme Court, Justice Stevens is just­ly being hailed for his intel­lect, inde­pen­dence, lead­er­ship, and grace. I would add anoth­er encomi­um: inno­v­a­tive legal prob­lem solver. I don’t mean some­one who looks to the law to solve social prob­lems. I mean a judge who looks to the law to solve its own prob­lems – some­one who believes deeply in the law’s integri­ty but instead of assum­ing the law is per­fect, assumes it has a capac­i­ty for self-correction.

The mean­ing of the Eighth Amendment as applied to the death penal­ty is an exam­ple of a legal prob­lem Justice Stevens has led the Court in try­ing to solve. The Eighth Amendment is prob­lem­at­ic, of course, because it oblig­es judges to inval­i­date cru­el and unusu­al pun­ish­ments” while pro­vid­ing so lit­tle evi­dence of its mean­ing that it tempts judges to enforce their own, not the law’s, val­ues. Nor are there easy fix­es, such as Justice Scalia’s idea that the pro­vi­sion only bans pun­ish­ments not autho­rized by statute – as if cru­el and unusu­al” meant cru­el and ille­gal” and didn’t bear at all on whether, for exam­ple, Congress or a state leg­is­la­ture could pre­scribe death as a pun­ish­ment for illegal immigration.

Justice Stevens joined the Court soon after Furman v. Georgia (1972) inter­pret­ed the Eighth Amendment to bar whol­ly dis­cre­tionary death sen­tenc­ing. Every Justice wrote a sep­a­rate opin­ion, and no two of the five in the major­i­ty agreed on the same Eighth Amendment ratio­nale. Justices Brennan and Marshall thought the death penal­ty was cru­el and unusu­al per se for dif­fer­ent rea­sons. Justice Douglas found some­thing like an equal pro­tec­tion vio­la­tion in exist­ing prac­tice, giv­en dis­par­i­ties by race and wealth. Justice White found more of a sub­stan­tive due process vio­la­tion: Capital con­vic­tions too rarely prompt­ed death ver­dicts to pro­vide a deter­rent or ret­ribu­tive jus­ti­fi­ca­tion for state killing. Justice Stewart found a pro­ce­dur­al due process prob­lem: Absent stan­dards, there was no expla­na­tion for why one per­son got death and anoth­er didn’t.

In five cas­es decid­ed on July 2, 1976Gregg v. Georgia, Proffitt v. Florida, Jurek v. Texas, Woodson v. North Carolina, and Roberts v. Louisiana – Justices Stewart, Powell, and Stevens joint­ly authored opin­ions reach­ing three con­clu­sions: (1) The death penal­ty for mur­der isn’t always con­sti­tu­tion­al or uncon­sti­tu­tion­al; (2) Louisiana and North Carolina could not pun­ish all mur­ders with death and instead had to indi­vid­u­al­ize” death sen­tenc­ing; (3) on their faces, Florida, Georgia and Texas’s guid­ed dis­cre­tion” statutes held out a prospect of con­sti­tu­tion­al­ly iden­ti­fy­ing mur­ders suf­fi­cient­ly egre­gious to war­rant death, but deter­min­ing whether they did so in prac­tice would require ongo­ing scruti­ny. The remain­ing Justices vot­ed either to val­i­date or inval­i­date all five statutes, so the Stewart-Powell-Stevens opin­ions pro­vid­ed the only con­sis­tent basis for the mixed decisions.

By revers­ing the usu­al pref­er­ence for as-applied over facial review, and by vow­ing to scru­ti­nize the details of statutes and sen­tences to decide the con­sti­tu­tion­al­i­ty of par­tic­u­lar cap­i­tal-sen­tenc­ing cas­es, cat­e­gories and pat­terns, the plu­ral­i­ty com­mit­ted the Court and States to a process of coop­er­a­tive­ly resolv­ing remain­ing inter­pre­tive prob­lems. Over the next sev­en years, a series of deci­sions in which only Justices Stevens and Stewart (when the lat­ter was still on the Court) were con­sis­tent­ly in the major­i­ty fleshed out this innovative approach.

In rul­ing that death is a cru­el and unusu­al pun­ish­ment for rape (Coker v. Georgia (1977)) and for minor par­tic­i­pants in felonies result­ing in death (Enmund v. Florida (1982)), the Court used counts of state statutes and jury ver­dicts to reveal the nation’s moral going rate” for pun­ish­ing those crimes. As a bul­wark against sub­sti­tut­ing their own val­ues for the moral judg­ment the Eighth Amendment clear­ly calls for but doesn’t ful­ly define, the Justices took coun­sel from the aggre­gate con­clu­sions of oth­er demo­c­ra­t­ic insti­tu­tions. But to pre­serve its own duty to say what the law is, the Court treat­ed the head count of statutes and ver­dicts as per­sua­sive but not mechan­i­cal­ly deci­sive. Later on, the Court used the same approach to find that death is cru­el and unusu­al pun­ish­ment for men­tal­ly retard­ed offend­ers (Atkins v. Virginia (2002)) and juve­niles (Roper v. Simmons (2005)) who kill, and for the rape of a child (Kennedy v. Louisiana (2008)). In the 1980s, the Court had upheld the death penal­ty in the first two of these sit­u­a­tions. But start­ing with Justice Stevens’ pow­er­ful deci­sion in Atkins, the Court found that the demo­c­ra­t­i­cal­ly revealed moral cen­ter of grav­i­ty had shift­ed away from death more recently.

The hard­er ques­tion is how the Eighth Amendment dis­tin­guish­es between mur­ders that may and may not be pun­ished by death. Here, the Court didn’t sim­ply mine exist­ing demo­c­ra­t­ic judg­ments for evi­dence of the nation­al going rate. Instead, in cas­es such as Lockett v. Ohio (1978) and Godfrey v. Georgia (1980), the Court read the Eighth Amendment to require new pro­ce­dures through which demo­c­ra­t­ic actors in each State would iden­ti­fy the core” set of sit­u­a­tions in which its cit­i­zens con­sis­tent­ly find death to be appro­pri­ate. State leg­is­la­tures had to spec­i­fy aggra­vat­ing fac­tors beyond the ele­ments of mur­der that mark death-eli­gi­bil­i­ty. State courts had to inter­pret the fac­tors objec­tive­ly and nar­row­ly. Juries had to con­sid­er all mit­i­gat­ing fac­tors to be sure the killing remained at the core once aggra­va­tion was net­ted out by mit­i­ga­tion. Occasionally, the Court itself would look at indi­vid­ual cas­es and pat­terns of death ver­dicts to see if the State in fact had a mean­ing­ful basis for dis­tin­guish­ing death from non-death cases.

After Justice Stewart left the Court, Justice Stevens elab­o­rat­ed the approach. In Stevens’ view, States deserved flex­i­bil­i­ty in devel­op­ing strate­gies for iden­ti­fy­ing the core. For exam­ple, his major­i­ty opin­ion for the Court in Zant v. Stephens (1983) allowed States to use nar­row aggra­va­tors, a broad invi­ta­tion for mer­cy,” and appel­late review of sen­tenc­ing pat­terns to be cer­tain that cap­i­tal ver­dicts clus­ter at a dis­cern­able core and to over­turn out­liers. In a sep­a­rate opin­ion respect­ing the denial of cer­tio­rari in Smith v. North Carolina (1982), Stevens praised States that instead allowed juries to impose death only when aggra­va­tion sub­stan­tial­ly out­weighed mit­i­ga­tion. As Stevens sug­gest­ed in his dis­sent in McCleskey v. Kemp, dis­cussed below, the Court could com­plete the process of sur­fac­ing and enforc­ing a demo­c­ra­t­i­cal­ly val­i­dat­ed moral con­sen­sus about the mur­ders for which death is and is not cru­el and unusu­al pun­ish­ment” by com­par­ing each State’s core to the oth­ers and invalidating outliers.

Starting in the late 1980s, how­ev­er, a chang­ing major­i­ty of the Court backed away from this jurispru­dence. With Justice Stevens in dis­sent, the Court approved aggra­vat­ing fac­tors that hard­ly nar­row at all (Walton v. Arizona (1990); Payne v. Tennessee (1991)), refused to deter­mine if States con­sis­tent­ly apply sus­pect aggra­va­tors (Arave v. Creech (1993)), let States lim­it the uses juries make of mit­i­ga­tion (Graham v. Collins (1993)), allowed death sen­tences in cas­es nowhere near the aggra­vat­ed core, as when aggra­va­tion and mit­i­ga­tion are equal (Kansas v. Marsh (2006)), let states lim­it cap­i­tal juries to strong death penal­ty sup­port­ers (Uttecht v. Brown (2007)), and allowed state supreme courts that had promised to review death sen­tenc­ing pat­terns to stop doing so (Walker v. Georgia (2008)).

McCleskey v. Kemp (1987) was the deci­sive case. It reviewed the con­sti­tu­tion­al­i­ty of Georgia’s cap­i­tal statute as applied in light of a study show­ing that after con­trol­ling for legit­i­mate fac­tors, offend­ers con­vict­ed of killing whites were four times more like­ly to receive death than killers of blacks. Justice Powell con­clud­ed for five jus­tices that the Court had done all it could to con­trol racial­ly dis­parate death-sen­tenc­ing pat­terns. Those that remained were the price of main­tain­ing social order – a con­clu­sion Justice Powell pub­licly regret­ted after he left the Court. Justice Brennan’s pas­sion­ate dis­sent argued that racial­ly skewed deci­sions to take life are too high a price to pay for any social good.

Justice Stevens’ short dis­sent was the swan song of the prob­lem-solv­ing approach. He not­ed that the case didn’t present trag­ic choic­es; legal devices at hand could solve the inter­pre­tive prob­lem. The study before the Court showed that racial dis­par­i­ties van­ished when aggra­va­tion sub­stan­tial­ly out­weighed mit­i­ga­tion. If the Court held to its ear­li­er insis­tence that States define a core set of only the worst of the worst cas­es, and if the Court were will­ing to review States’ cores” for invalid out­liers, which Georgia’s appeared to be, the Eighth Amendment would yield a demo­c­ra­t­i­cal­ly attest­ed mean­ing that sac­ri­ficed nei­ther social order nor fun­da­men­tal prin­ci­ples of equality.

In Baze v. Rees (2008), the Court upheld exe­cu­tions by lethal injec­tion. In a sep­a­rate opin­ion, Justice Stevens wrote that he had changed his mind about the death penal­ty and now viewed it as cru­el and unusu­al pun­ish­ment in all cas­es for lack of suf­fi­cient jus­ti­fi­ca­tion. Stevens offered sev­er­al rea­sons for his change of heart, but a main one was the Court’s refusal to do its part – after many States had done theirs – to sur­face a demo­c­ra­t­i­cal­ly val­i­dat­ed nation­al con­sen­sus through which the Eighth Amendment could iden­ti­fy death ver­dicts that were and were not cru­el and unusual.

It is char­ac­ter­is­tic of Justice Stevens’ com­mit­ment to the integri­ty of the law and the Court that, even after con­clud­ing that the Court’s thir­ty-six-year effort to iden­ti­fy crimes for which death is an appro­pri­ate pun­ish­ment had failed, he nonethe­less vowed to con­tin­ue apply­ing the Court’s doc­trine as best he could. It is also char­ac­ter­is­tic of Justice Stevens that, in los­ing the bat­tle on the Court, his strong­ly rea­soned view won the day in the demo­c­ra­t­ic insti­tu­tions to which he appealed for inter­pre­tive guid­ance. Since 1999, the num­ber of death sen­tences imposed in the nation has dropped from three hun­dred to about one hun­dred a year, and the num­ber of exe­cu­tions has declined. Even vocal pro-death-penal­ty pros­e­cu­tors are com­mit­ted to lim­it­ing the death penal­ty to the worst of the worst.” One rea­son for the change is the grad­ual adop­tion by many juris­dic­tions of the nar­row­ing steps Justice Stevens advocated.

The legal prob­lems the death penal­ty and the Cruel and Unusual Punishment Clause pose are far from being solved. But by show­ing how a pro­vi­sion as prob­lem­at­ic as the Cruel and Unusual Punishment Clause can be read to enlist oth­er demo­c­ra­t­ic actors in help­ing to cure its imper­fec­tions while pre­serv­ing its integri­ty, Justice Stevens has pro­vid­ed a mod­el for solv­ing the biggest prob­lem the Court is thought to face – the counter-majoritarian difficulty.
