10 The data stem from the Commission's annual reports on the implementation of EU law (c.f. {http://europa.eu/generalreport/en/rgset.htm} chapters XXIII). It encompasses all infringement cases for the EU-12 member states that have been opened after 1978, have reached the ECJ and have been terminated before 31 January 2000. The total number of ECJ cases is 2343, of which 1092 have been withdrawn before a Court judgment. The duration of non-compliance is measured by the days between the ECJ judgment and the termination of the case. The European Commission is responsible for the latter and bases its decision on its assessment of compliance with the judgment.

13 Although there is no empirical evidence for such informal bargaining in publicly accessible materials (protocols of European Advocate Generals, ECJ judgments), this alternative explanation is tested in part V.

14 In this mode of action, actors are consciously motivated to become persuaded by good arguments J. Habermas, Theorie des Kommunikativen Handelns. Band 1 Handlungsrationalität und gesellschaftliche Rationalisierung (Frankfurt: Suhrkamp, 1995); H. Müller, ‘Arguing, Bargaining and all that’ p. 402ff.; H.

15 J. Habermas, Moralbewußtsein und kommunikatives Handeln (Frankfurt am Main: Suhrkamp, 1983); Deitelhoff and H. Müller, ‘Theoretical Paradise’ p 167ff.

16 These approaches assume that contextual variables accelerate the quantity of argumentative speech acts, which automatically translates into persuasion so that arguing is effective, once it takes place. (T. Risse, ‘Konstruktivismus, Rationalismus und die Theorie Internationaler Beziehungen – Warum empirisch nichts so heiß gegessen wird, wie es theoretisch gekocht wurde’, in G. Hellmann, K. D. Wolf and M. Zürn (eds), Forschungsstand und Perspektiven der Internationalen Beziehungen in Deutschland (2002), pp. 1–26).

17 There is one important exception: The ECJ can issue financial penalties since 1993 (Art. 228 ECT) if states fail to comply with its first judgment.

26 An example for a mismatch would be a narrow interpretational method applied to a complex problem. Interpreting different articles or paragraphs with the wording method can lead to completely different interpretations of the whole norm. Yet, the wording technique of interpretation cannot solve the problem of which article or paragraph (and their associated interpretations) should be given priority.

36 The empirical analysis rests on a broad range of material including interviews, protocols of the ECJ case, parliamentary speeches, newspaper articles and texts of relevant legal norms. ECJ cases are often politically sensitive and issues can be classified. Accordingly, some interviewees hesitated to give detailed information on micro processes of persuasion and adaptations. Therefore, much of the evidence for policy adaptations and underlying justifications is based on primary sources rather than interviews.

38 ‘The German Government goes on to argue that the directive does not require the incorporation in domestic legislation of the obligation of notification laid down by Article 9(1) and Article 10(3) of the directive on the ground that that obligation ensues directly from the directive.

53 For reasons of space, this article focuses on the communicational requirements. The other issue (‘states of emergency’ as precondition for exceptions) was solved early in the judicial discourse.

66 The ECJ also followed this line of argumentation and ruled in its judgment on November 1992 that the DWD required complete reports of all granted exceptions (European Court of Justice, ‘Court Judgment’, pp. 29, 31). The ECJ usually issues judgments, if legal changes are not completed during ongoing judicial discourses. Thus, Court judgments do not necessarily indicate that preceding judicial discourses failed.

70 The ministry could have relied on the (broader) systematic argument that the federal loyalty principle precludes the legalisation of any explicit information rules (as argued in the early stage of the discourse), in order to defend its initial position. But this argument would not have exactly addressed the issue at stake, would not have been compatible with the professional opinions of the advocates, and would hardly have been accepted by the European enforcement authorities. Hence, after the judicial discourse produced an interpretation that was intersubjectively valid among the advocates of the parties, it would have been irrational (since most likely unsuccessful) and inappropriate of the German government to use a deviating argument any longer.

77 In addition, the government invested 11,000,000 DM in laboratories of water providers and other institutes, in order to enable them to comprehensively check the quality of drinking water (Bundestag, ‘Plenarprotokoll vom 5.02.1992’, p. 55; Bundestag, ‘Beschlussempfehlung und Bericht des Ausschusses für Gesundheit' 07.12.1992’, p. 4).

78 The comprehensive and quick legal adaptation is remarkable. The DWP draft required the approval of the Bundesrat, because implementation issues as competencies of the Länder were at stake. However, especially CDU governed Länder opposed comprehensive reporting requirements (Bayern, ‘Antrag 24.09.1992’; Bundesrat, ‘Plenarprotokoll 25.09.1992’). Even the Bundesrat’s Committee for Health proposed scope restrictions to the informational requirements in the governmental draft DWP (Bundesratsausschuss für Gesundheit, ‘Empfehlungen zur Allgemeinen Verwaltungsvorschrift über Trinkwasser, 14.09.1992’, p. 2, Bundesrat, ‘Plenarprotokoll 25.09.1992’, p. 487). The Kohl-government managed to pass the DWP against this scepticism and prescribed communicational requirements for deviations from all parameters for geogen and for meteorological reasons. The DWP ensured the comprehensive collection of information on exceptions and derogations from local authorities to the federal ministry for health. It did not encompass windows of opportunities for future less demanding norm interpretations; did not entail unspecified or ambiguous new concepts and did not create overlaps with other bodies of law, but resembled a demanding form of compliance. (Bundesgesundheitsministerium, ‘Allgemeine Verwaltungsvorschrift zu Trinkwasser, 09.07.1992’, pp. 1, 6).

84 Even after the European Commission had closed the case, the government did not shift back towards a less demanding and less costly form of compliance, but maintained its new policies (Bundestag, ‘Plenarprotokoll vom 04.03.1993’, pp. 12355C-21360D., Bundestag, ‘Plenarprotokoll vom 20.01.1994’, pp. 17766–96.).

91 According to the directive-immanent teleological line of reasoning, communicational requirements had to be legally prescribed. Otherwise, the Commission could not fulfill its monitoring function; European Court of Justice, ‘Court Judgment of 24 November 1992’, p. 28; Advocate General, ‘Opinion of the Advocate General’, pp. 17ff.

109 Moreover, the institutional logic of judicial discourses should theoretically prevent strategic rational governments from posing restrictions on their advocates. The only change to pursue national interests at least partially before the ECJ is to convince the European advocate and the ECJ judges of the superiority of the state’s norm interpretation. Merely repeating one and the same argument, regardless of the arguments of the other party, or sticking to a judicial method which does not fit to the interpretational problem will neither convince other advocates nor the ECJ judges. In order to be persuasive, it is essential to engage in judicial argumentation and to flexibly react to the arguments of others. Hence, if governments restrict the freedom of maneuver of their advocates, they risk to be unpersuasive and to end up with suboptimal outcomes.
