Let Not Triepel Triumph – How To Make the Best Out of Sentenza No. 238 of the Italian Constitutional Court for a Global Legal Order

Written by

The Italian Constiutional Court’s decision no. 238 of 22 Oct. 2014 (unofficial translation into English) already inspired a flurry of comments in the blogosphere (see in EJIL talk! Christian Tams (24 Oct. 2014) and Theodor Schilling (12 Nov. 2014); on the Verfassungsblog amongst others Filippo Fontanelli (27 Oct. 2014); on Opinio Juris Andrea Pin (19 Nov. 2014); on the Völkerrechtsblog Felix Würkert (11 Dec. 2014)).

In that Sentenza, the Corte refused to give effect to the ICJ’s judgment (in) Jurisdictional Immunities of the State (Germany v. Italy) of 3 February 2012, in which the ICJ had upheld the principle of state immunity against allegations of serious human rights violations of German state organs committed during the Second World War.

Sentenza No. 238 is important not only because it concerns the persisting tension between respecting (state) immunity and protecting human or fundamental rights (see for a recent publication Anne Peters/Evelyne Lagrange/Stefan Oeter/Christian Tomuschat (eds), Immunities in the Age of Global Constitutionalism (Leiden: Brill 2015)), but – maybe even more importantly – because it concerns the relationship between international law (in the shape of a judgment by the ICJ) and domestic law, as applied by a domestic (constitutional) court.

Just the latest item in the sequence of domestic courts’ resistance against decisions of international bodies  

The Corte relied on its established case-law on the effects of European Union law, notably on the doctrine of controlimiti in order to erect a barrier to the “introduction” of the ICJ judgment into the domestic legal order: “As was upheld several times by this Court, there is no doubt that the fundamental principles of the constitutional order and inalienable human rights constitute a ‘limit to the introduction (…) of generally recognized norms of international law’ (…) and serve as ‘counterlimits’ [controlimiti] to the entry of European Union [and now international] law” (Sentenza No. 238, in “The law”, para. 3.2.).

The Italian controlimiti-approach to European or international court decisions is by no means an outlier. Quite to the contrary, the Sentenza No. 238 is just one more building block in the wall of “protection” built up by domestic courts against “intrusion” of international law, relying on the precepts of their national constitution. Ironically, this front of resistance (which now deploys effects “against” Germany) had been spearheaded by the German Constitutional Court (Bundesverfassungsgericht, BVerfG). In the 1970s, that Court mounted critique against an insufficient respect for human rights by the then European Community (BVerfGE 37, 271 (1974) – Solange I) and threatened to scrutinize EC-acts against the yardstick of domestic fundamental rights and to refuse to allow their application in Germany. In 2004, the BVerfG denied a strictly binding effect of the ECHR and ECtHR-judgments, and instead (only) ordered German authorites and courts to “take into account” the Convention and Strasbourg judgments, and only within the confines of the German Basic Law (BVerfGE 111, 307 (2004) – Görgülü).

How do these domestic decisions resemble each other and in what respects do they differ, on a purely technical level and in their tone? Sentenza No. 238 repeats that any international norm (or international judgment) which stands in conflict with “principi fondamentali dell’ ordinamento costituzionale” may not be applied by domestic institutions. The German BVerfG in Görgülü had marked the boundary of applicability of judgments of the ECtHR with exactly the same wording (“tragende Grundsätze der Verfassung”).

The referring court of Florence had quoted a previous constitutional judgment pointing to the “identità” of the Italian legal order. There, the Corte had “reaffirmed the principle that ‘the tendency of the Italian legal order to be open to generally recognized norms of international law and international treaties is limited by the necessity to preserve its identity; thus, first of all, by the values enshrined in the Constitution’” (Sentenza No. 238, facts, para. 1.2., quoting Judgment No. 73/2001). This is exactly what other European courts have done before (albeit with regard to EU law): the Spanish Constitutional Court (declaration DTC 1/2004 of 13 December 2004, Sec. II para. 3), the French Conseil constitutionnel (décision no 2006-540 DC of 27 July 2006, para. 19) and the German Constitutional Court (2 BvE 2/08 of 30 June 2009, para. 340 − Treaty of Lisbon). (See also Constitutional Court of Lithuania, case no 17/02-24/02-06/03-22/04 on the priority of the state constitution over EU law, 14 March 2006, sec. III. para. 9.4.).

Just like the US Supreme Court’s Medellín decision (Medellín v. Texas, 552 U.S. 491 (2008)), Sentenza No. 238 is directed against an ICJ judgment. Medellín also had to do with constitutional principles, namely with federalism and the separation of powers: the domestic issue here was that the US President had ordered implementation of the ICJ Avena judgment in the different states. Medellín was however not concerned with respect for fundamental rights of individuals. Another difference is that Medellín held that an ICJ judgment was not in itself self-executing but needed a federal law to be implemented domestically. Sentenza No. 238 was not concerned with self-executingness, because Italy had, in the statute incorporating the UN Convention on State Immunity, which was adopted after the ICJ judgment, inserted a specific provision which obliged Italian judges to adapt themselves to judgments of the ICJ (Law no. 5 of 14 January 2013). Exactly that provision (Art. 3) was now declared unconstitutional.

Sentenza No. 238 is in some way a follower of the ECJ Kadi decision (ECJ, 3 September 2008, Kadi and Al Barakaat, joint cases C-402/05 P and C-415/05 P, ECR 2008, I-6351), which the Corte quotes. But unlike Kadi, which mounts resistance against the Security Council and thus against a partly unelected and not fully representative body, Sentenza No. 238 is directed against the International Court of Justice, a body of elected judges who represent all regions of the world (is it enough to consider it representative?). Generally speaking, this Court has so far enjoyed a high degree of acceptance. The de facto-disobedience to the ICJ seems less justified as a matter of principle, and implies more serious damage to the normativity of the international legal system than disobeying the Security Council.

Just like Kadi, Sentenza No. 238 insists on the fact that it has nothing to do with “outbound” compliance of the state (Italy) with international law, but only concerns the internal compatibility of two Italian laws with the Italian constitution: “The result is a further reduction of the scope of this norm, with effects in the domestic legal order only.” (in “The law”, para. 3.3., emphasis added). Put differently, the Corte neatly distinguishes “internal” and “external” effects of an international norm: “The impediment to the incorporation of the conventional norm [Article 94 of the United Nations Charter] to our legal order – albeit exclusively for the purposes of the present case – has no effects on the lawfulness of the external norm itself, and therefore results in the declaration of unconstitutionality of the special law of adaptation, insofar as it contrasts with the abovementioned fundamental principles of the Constitution“ (in “The law“, para. 4.1, emphasis added). So technically (in a dualist world view), the case is not about supremacy but about incorporation: “Accordingly, the incorporation, and thus the application, of the international norm would inevitably be precluded, insofar as it conflicts with inviolable principles and rights. This is exactly what has happened in the present case.” (in “The law”, para. 3.4, emphasis added).

The pretense that the “internal” unconstitutionality basically does not concern international law, and that the decision does not formally accord any priority or supremacy to internal law is as unpersuasive as it has been in the ECJ Kadi judgment (ECJ, Kadi, paras 287-288 and 299). That distinction between inside and outside resonates the good old 19th century dualism as formulated by Heinrich Triepel, according to which international law and domestic law are “two circles which at best touch each other but which never intersect” (Heinrich Triepel, Völkerrecht und Landesrecht (Leipzig: Verlag von C. L. Hirschfeld 1899), p. 111, my translation).

The Court’s consolation that “in any other case, it is certainly clear that the undertaking of the Italian State to respect all of the international obligations imposed by the accession to the United Nations Charter, including the duty to comply with the judgments of the ICJ, remains unchanged.” (Sentenza No. 238, in “The law”, para. 4) does not help much for managing the practical problem at stake.

What can Germany do in the short term?

Which venues are open for Germany to react lawfully against Sentenza No. 238? First, Germany might have recourse to the UN Security Council under Art. 94(2) UN Charter. This provision is applicable as soon as a UN member states “fails to perform the obligations incumbent upon it under a judgment rendered” by the ICJ. The admission of complaints against Germany by Italian courts constitute such a failure, because it disregards the procedural barrier to domestic judicial proceedings against a state protected by immunity. Decisions of Italian courts are imputable to Italy (cf. Art. 4 of the ILC articles on state responsibility).

A lex specialis to Art. 94(2) UN Charter seems to be Art. 39 of the European Convention for the Peaceful Settlement of Disputes of 29 April 1957, the convention which was the jurisdictional basis for the ICJ proceedings that had led to the 2012 judgment. Under Art. 39, Germany could appeal to the Committee of Ministers of the Council of Europe, which could with a 2/3 majority “make recommendations with a view to ensuring compliance with the (…) decision” directed at Italy.

Instead (in any case after failure of diplomatic representations), Germany might institute a new complaint against Italy for violation of state immunity, as authoritatively spelled out by the ICJ judgment. Remember that the ECtHR in Case of Jones and others v. UK (appl. nos. 34356/06 and 40528/06, judgment of 14 Jan. 2014) had held that the judgment of the ICJ in Germany v. Italy “must be considered (…) as authoritative as regards the content of customary international law” (para. 197).

Res iudicata does not stand against the institution of ICJ-proceedings, because the disregard of the ICJ judgment of 2012 constitutes a new issue. Also, the possibility of having recourse to the Security Council under Art. 94(2) of the UN Charter does not preclude such a complaint, because the two venues are in nature distinct (calling on the Security Council is a political path as opposed to a judicial path) and can be resorted to cumulatively. (On 25 Nov. 2014, one month after the Sentenza No. 238, Italy declared its general recognition of the jurisdiction of the ICJ under the optional clause of Art. 36(2) ICJ Statute), implicitly inviting a second proceeding.)

Sentenza No. 238 itself does not yet constitute an internationally wrongful act, because it does not in itself disregard state immunity. What counts are the lower courts’ reconsiderations of the claims, their decisions on holding them admissible by setting aside state immunity. Arguably, already the re-opening of those proceedings, not only decisions on their merits or the execution of a judgment, constitute internationally wrongful acts. The content of Italian state responsibility would then be primarily restitution in kind which would in our case mean to somehow strike down the proceedings against Germany.

Moroever, any execution of a substantive judgment would in addition violate post-judgment immunity against execution. The relevant parts of the pertinent provision of Art. 19 of the UN Convention on State Immunity of 2004 seem to express customary international law. The most attractive German object of execution, the Villa Vigoni, is protected, because it serves governmental objectives in a wider sense, including cultural policy, and it has a non-commercial character (ICJ, Jurisdictional Immunities, para. 119).

Art. 60 sentence 2 of the ICJ-Statute does not prevent a new proceeding before the ICJ, because this provison is not applicable (Cf. ICJ, Request for Interpretation of the Judgment of 31 March 2004 in the Case Concerning Avena and Other Mexican Nationals (Mexico v. United States of America), judgment of 19 January 2009). The issue is not a one of clarifying the meaning of the ICJ judgment of 2012. There is no “dispute as to the meaning or scope” of that judgment.

Another pertinent provision is Art. 30 of the European Dispute Settlement Convention of 1957 which deals with the situation that the state found in breach of international law by the ICJ does not or cannot honour the ICJ judgment: “[I]f the municipal law of that party [in our case Italy] does not permit or only partially permits” to make good the breach of international law found by the ICJ, “the Court (..) shall, if necessary, grant the injured party equitable satisfaction.” But such a potential new decision by the ICJ could only confer “equitable satisfaction”, and this is not what serves Germany.

What should everybody (notably courts) do in the long term?

Beyond these conventional, more confrontational means of reacting to the Italian breach of international law as it stands, all parties are advised to better prevent and manage such regime collisions. What is needed is the further development of procedural mechanisms of reciprocal restraint, respect, and cooperation needed for the adjustment of competing claims of authority, in order to realize what has been called a “pluralisme ordonné” (Mireille Delmas-Marty) – as opposed to a dualism à la Triepel.

Domestic (constitutional) courts do and should take into consideration international law in good faith and interpret the domestic constitution in the light of international law. Along this line, the Corte could have interpreted the (constitutional) right of access to a court under Art. 24 of the Italian Constitution in the light of ECtHR, Sfountouris v Germany, appl. no. 24120/06 (31 May 2011) which implicitly held that access to domestic courts (in Germany) in suits for damages on account of German World War II-crimes appear to satisfy the standards of Art. 6 ECHR (pp. 16-18; this decision on inadmissibility found a claim based on Art. 1 AP 1 in conjunction with Art. 14 ECHR to be inadmissible ratione materiae).

The Corte could have used a more more “harmonising” approach à la Jones. Here the ECtHR had insisted that both different issue areas of international law, the law of immunities, and human rights law, must be reconciled, acknowledging “the need to interpret the Convention so far as possible in harmony with other rules of international law of which it forms part, including those relating to the grant of State immunity” (ECtHR, Jones para. 189). This led the ECtHR “to conclude that measures taken by a State which reflect generally recognised rules of public international law on State immunity cannot in principle be regarded as imposing a disproportionate restriction on the right of access to a court” (ibid).

Third, the Corte could have applied the Bosphorus strategy (ECtHR, Bosphorus v. Ireland, appl. no 45036/98, 30 June 2005). In that approach, courts should employ a legal presumption that a legal act performed by a body rooted in “another” legal system is in conformity with the “own” standards, coupled with the reciprocal recognition of such acts, “as long as” some minimum requirements are not undercut. In this scheme, domestic courts renounce on revisiting (judicial or quasi-judicial) decisions taken by an international body on the basis of the rebuttable presumption that the respective international regime, or another state’s domestic legal system (in our case Germany) offers a functionally equivalent legal protection.

Most importantly, conflicts between international law and constitutional law should be resolved by balancing in the concrete case, not on the basis of a normative hierarchy or the norms’ expression in international law as opposed to domestic law. Less attention should be paid to the formal sources of law, and more to the substance of the rules in question. The ranking and effects of the norms at stake should be assessed in a more subtle manner, according to their substantial weight and significance. Such a nonformalist, substance-oriented perspective implies that on the one hand certain less significant provisions in state constitutions would have to give way to important international norms. Inversely, fundamental rights guarantees should prevail over less important norms (independent of their locus and type of codification). The fundamental idea is that what counts is the substance, not the formal category of conflicting norms. (Admittedly, this new approach does not always offer strict guidance, because it is debatable which norms are “important” in terms of substance). Still, such a flexible approach appears to correspond better with the current state of global legal integration than does the idea of a strict hierarchy, particularly in human rights matters. From this perspective, international law, constitutional law, and other states’ constitutional law, too, find themselves in a fluent state of interaction and reciprocal influence, based on discourse and mutual adaptation, but not in a hierarchical relationship.


The stability of the inter-state system which state immunity seeks to protect is sustainable only if it is perceived as being fair. The persistence of a de facto non-accountability for state-sponsored crimes undermines this sustainability. Concedely, the widespread unease about upholding immunity even against allegations of serious human rights violations is particularly pronounced in the context of criminal proceedings against individual officials who are suspect of being personally responsible for ordering or commiting crimes. For example, in a criminal proceeding in Switzerland against a former Algerian minister of defence, instituted for torture, the Swiss Federal Criminal Tribunal granted no immunity ratione personae for acts which the minister had allegedly committed when still in office (Swiss Federal Criminal Tribunal, decision of 25 July 2012, BBl. 2011, 140).

It is often said that the so-called “civil” (rather “public law”) proceedings against states (adressed as juridical persons), such as the case underlying Sentenza No. 238, should in normative terms be assessed differently from criminal proceedings against individuals, and that – if at all – a human rights exception is more appropriate in the latter context. I hesitate to agree. In cases of torture and the like, the criminals are normally office holders whose actions are imputable to states, so that both tracks (individual criminal responsibility and state responsibility) will normally be pursued in parallel. From the perspective of the victim, it is not self-evident that the claim against a juridical person which seeks a statement of state responsibility and damages should be less worthy of being honoured than the request for a criminal penalty against a perpetrator. For example, the recent important ECtHR case, Jones v. UK, was a case on state immunity (involving Saudi Arabia) against allegations of torture. Here the ECtHR observed that “in light of the developments currently under way in this area of public international law, this is a matter which needs to be kept under review” (para. 215). However, in comparison to such type of dispute about torture of current or recent regimes, the issue of the Italian prisoners of war makes a bad case for two reasins. First, an international law-based entitlement of victims of of violations of the law of armed conflict to financial compensation is still denied by most domestic courts. Second, the claim concerns crimes committed more than one generation ago. Even if we do not accept any formal prescription for the prosecution of such egregious crimes, the lapse of time does weaken the claims.

Is the openness of the question “who decides who decides” and the lack of an ultimate authority – in our context for example a tribunal sitting over and above the ICJ and the Italian Corte Costituzionale – a merit of the global order? In theory, such openness constitutes an additional mechanism for limiting power and seems to allow for a heterarchical adjustment of regimes. Within this paradigm, the constitutional resistance of the Corte Costituzionale might be interpreted as the pulling of an “emergency brake” whose availability had been the pre-condition for the opening-up of the states’ constitutions towards the international sphere in the first place. Along this line, one could argue that – in the absence of a super-arbiter − the Italian courts are entitled to act as “guardians” of rights of the victims or their descendants “as long as” a customary human rights exception to state immunity has not cristallized or until a special agreement between Germay and Italy, on a special indemnation programme or a special claims tribunal, has been concluded.

In the long run, reasonable resistance by national actors – if it is exercised under respect of the principles for ordering pluralism, notably in good faith and with due regard for the overarching ideal of international cooperation – might build up the political pressure needed for promoting the progressive evolution of international law in the direction of a system more considerate of human rights. Indeed, such domestic resistance has in the past had salutary effects in the sense that it stimulated an improvement of the attacked regime’s fundamental rights protection: In reaction to the German Constitutional Court’s Solange I decision, the EC/EU formalised its scheme of fundamental rights protection culminating in the European Charter of Fundamental Rights and – perhaps – the accession of the EU to the ECHR. Arguably, it has been in reaction to the ECJ’s Kadi decision and its progeny that the United Nations 1267-sanctions regime was complemented with an ombudsman procedure (UN SC Res 1904 (2009)) which has been gradually improved (UN SC Res. 1989 (2011)).

Superficially, the Sentenza No. 238 strengthens the position of the individual against the state. But on a more profound level, it strengthens unilateralism over universalism: It gives priority to one (state’s) national outlook about what constitutes a proper legal order over the universal standard pronounced by an international court. Concededly, this ICJ-standard is unsatisfactory and seems to be biased in favour of the stability of an inter-state system. On the other hand it still has the merit of being universal. The lack of an ultimate arbiter tends to result in the political dominance of the more powerful actors which are normally the domestic ones such as the Italian Constiutional Court. And a stiff dualism à la Tripel and Tesauro bears the real risk of reinforcing the perception that international law is only soft law or even no law at all.

Despite its staunch dualism, the Corte insinuates that (somehow), the two legal circles (to use Triepel’s term) may interact: “At the same time, however, this [declaration of unconstitutionality] may also contribute to a desirable – and desired by many – evolution of international law itself” (ibid., in “The law”, para. 3.3.). However: You cannot have the cake and eat it, too.

Dear Ms. Peters, thank you for your insightful and quite exhaustive review of the Corte's decision and its possible consequences, desirable or otherwise. I see however a certain contradiction between two of your proposals for future dealings with similar constellations. On the one hand, you claim, correctly in my view, that "What is needed is the further development of procedural mechanisms of reciprocal restraint, respect, and cooperation needed for the adjustment of competing claims of authority", and offer three very plausible possibilities. On the other hand, you advocate a "substance-oriented perspective" under which "fundamental rights guarantees should prevail over less important norms". This, it seems to me, is the very opposite of a procedural mechanism, and it also seems to justify the Corte's decision which you otherwise appear to criticise. In the end however, you clearly privilege universalism over unilateralism. But doesn't this imply, in the final analysis, that fundamental rights ought to prevail in case of conflict with other norms only if they are championed by international courts? Such a result would be difficult to reconcile with your hope that "national actors ... might build up the political pressure needed for promoting the progressive evolution of international law in the direction of a system more considerate of human rights." Or do you see all these aspects, and others you mention, as elements of a very complex balancing act? Again, thanks for your very stimulating piece.

Dear professor Dr Peters,
Allow me to congratulate you on the thorough and highly exhaustive doctrinal analysis of the CC’s judgment and its impact vis-à-vis the international legal order. Your learned contribution, as a specialist of international constitutional law, is evidently much appreciated.
However, I can’t help wondering what is the whole point of proclaiming humanity as the “Alpha and the Omega (Α/Ω)” of sovereignty, to cite your most influential article, if we are to conclude that war crimes’ atrocities and the individual compensatory claims arising out of them are to enjoy full impunity/immunity (respectively) on the grounds that the foreign sovereign does not wish or favour the reparation of an already stipulated injustice? If, ultimately, sovereignty implies responsibility and the acceptance of fundamental human rights as preponderate standards vis-à-vis the classical westphalian notions of the "suprema potestas" as a prerogative of mutual abstention, why not favouring a pro-human rights (pro-fundamental norms, to pose it in a slighlty more generalized manner) interpretation, no matter what the domestic court contends to have applied (internal fundamental law, regional human rights treaties etc.)? Furthermore, if we are to safeguard, on doctrinal terms, the universality of the legal system against the menace of unilateralism, I just wonder why the ICJ would remain the only “custodian” who (shall) “custodiet ipsos custodes (i.e. States)”? If universality is the greater stake, then why compliance with the universal standards forming part of the international community’s unwritten constitution (jus cogens norms, and especially fundamental human rights) cannot be rendered the ultimate telos of either domestic or international adjudication? All in all, universality is not just a procedural concept favouring cooperation through processes against unilateral State action, but also a core-idea regarding the order of values within the international sphere. To conclude, it is definitely agreed that the dualism "à la Triepel" must be repudiated; but does the same not apply on “souveraineté à la Bodin”?

From the U.S.: Medellin was more complex (see http://ssrn.com/abstract=1484842 ). The decision, constitutionally, left the State of Texas where it had been before President Bush issued his directive to the U.S. Att'y Gen. to communicate with state att'ys gen. that the ICJ decision was to be followed. See concurring opinion, etc. Under article VI, cl. 2 of the U.S. Const., "all" treaties are supreme law of the land binding the states. Not all of our judges realize that the word "all" means ALL treaties (even non-self executing treaties) but that is what the Founders and Framers and early cases recognized and expected. The U.S. Chief Justice obviously never took a course in international law (or did rather poorly) and demonstrated ignorance with respect to the U.S. Const. (e.g., stating several times that the U.S. Senate ratifies treaties of the U.S. and once that "Congress" (the full Congress) does so despite the well-known fact that the President makes and ratifies treaties).
Nonetheless, although rare, when there is an unavoidable clash between the U.S. Const. and treaty law of the U.S., the U.S. courts will follow the Const. even though the U.S. remains bound by the treaty and can suffer certain sanctions. E.g., Reid v. Covert (U.S. 1957).
It may be that most countries will do the same.

Thank you for this Christmas gift, Anne! I think you've reached a perfect balance with your comment. Others (see Theodor Schilling's comment above) would tell you that 'You cannot have the cake and eat it, too'. As far as I'm concerned, I don't want to disturb your admirable balance, except to recall that Italian prisoners of war (rectius: internees denied POW status) were in fact denied a meaningful remedy before the German courts. And that, Sfountouris aside, the ECtHR's approach to proportionality in state immunity cases appears entirely unsatisfactory. However, your post remains food for thought for everybody interested in commenting sentenza 238.

Caro Ricardo,
I hope you got some better Christmas presents than comments on sentenza No. 238! Thank you for your important clarifications. My contribution was primarily interested in the interaction between international law and domestic law, and among the different “regimes” (general international law versus human rights law), and how to coordinate/manage those. The field of immunities is just one example which illustrates the necessity to invent and apply accommodating devices /techniques. But it also shows that abstract principles of “accommodation" need to be tested on the ground! Input by you as one of the best connaisseurs of the intricacies of the law of immunities is most welcome.
