² Cf. Justice Holmes in Louiseville Gas & Electric Co. v. Coleman 277 US 32, 41 (1938) “When a legal distinction is determined, as no one doubts that it may be between night and day, childhood and maturity, or any other extremes, a point has to be fixed or a line has to be drawn, or gradually picked out by successive decisions, to mark where the change takes place. Looked at by itself, without regard to the necessity behind it, the line or point seems arbitrary. It might as well or nearly as well be a little more to one side or the other. But when it is seen that a line or point there must be, and that there is no mathematical or logical way of fixing it precisely, the decision of the legislature must be accepted unless we can say that it is very wide of any reasonable mark.” In the EU context the ECJ said in Case C-110/05 Commission v. Italy (Italian trailers) [2009] E.C.R I-000, para. [67] “Member States cannot be denied the possibility of attaining an objective such as road safety by the introduction of general and simple rules which will be easily understood and applied by drivers and easily managed and supervised by the competent authorities”.

¹⁶ Of course, the Court's decisions in this area do have an impact on the reverse issue of Community competence to act: any area of Member State regulation falling under one of the four freedoms becomes fair game for harmonisation under Article 95 EC. See e.g. Snell, J. “Who's Got the Power? Free Movement and Allocation of Competence in EC Law” (2003) 22 Y.E.L. 323Google Scholar; Davies, G., “Can Selling Arrangements be Harmonised?” (2005) 30 E.

¹⁸ Of course the “F” word is a controversial term to be applied to the EU. Here, I use it in its most neutral sense to describe a situation where “a society seeks to divide power between a central government and its component units”: Young, E., “Protecting Member State Autonomy in the European Union: Some Cautionary Tales from American Federalism” (2002) 77 N.Y.U. Law Rev. 1612, 1614Google Scholar. K. Lenaerts describes federalism as whenever a “divided sovereign is guaranteed by a national or supra-national constitution and umpired by the supreme court of the common legal order” (“Constitutionalism and the Many Faces of Federalism” (1990) 38 Am. J. Comp.L. 205, 263.

¹⁹ See Justice Jackson's views in Hood & Sons v. DuMond, 336 US 525, 539 (1949): the Commerce Clause embodies “the principle that our economic unit is the Nation”, a “federal free trade unit”. He continued: “Our system, fostered by the Commerce Clause, is that every farmer and every craftsman shall be encouraged to produce by the very certainty that he will have free access to every market in the Nation, that no embargoes will withhold his exports, and no foreign state will by customs duties or regulations exclude them. Likewise, every consumer may look to the free competition from every producing area in the Nation to protect him from exploitation by any.”

²³ Furthermore, because Congress has the power “to permit the states to regulate in a manner which would otherwise not be permissible” (per Chief Justice Stone in Southern Pacific Co. v. Arizona, ex rel Sullivan 325 US 761, 769 (1945)), a situation which is not permitted under EC law where the four freedoms apply equally to Community as well as to Member States measures (Case 15/83 Denkavit Nederland v. Hoofdproduktschap voor Akkerbouwprodukten [1984] E.C.R. 2171, para. [15]; Case C-51/93 Meyhui v. Schott Zwiesel Glaswerke [1994] E.C.R. I-3879, para. [11]), more attention is focused in the US on the political than the judicial level for resolving difficulties in inter-state commerce.

⁵⁴ See e.g. Case 270/83 Commission v. France (tax credits) [1986] E.C.R 273. France granted tax credits to shareholders receiving dividends from a company with a registered office in France but not to those with only a branch or agency in France (and a registered office in another Member State). By applying the principle of equal treatment to this situation the Court required the French tax system to treat a branch or agency having no legal personality in the same way as a company registered in France. If, as Banks notes (K. Banks, “The application of the fundamental freedoms to Member State tax measures: guarding against protectionism or second-guessing national policy choices” (2008) 33 ELRev. 482, 488) the Court had selected the treatment of a branch or agency of a nationally based company as the appropriate comparator, the outcome might have been different.

⁶³ His approach is based on “textualism and originalism”: S. Sachse, “United we Stand – but for How Long? Justice Scalia and New Developments of the Dormant Commerce Clause” (1999) 43 St. Louis U. L. J. 695, 703 citing Scalia J's remarks in Tyler Pipe Indus. v. Washington State Dept. of Revenue 483 US 232, 263 (1987), “historical record provides no grounds for reading the Commerce Clause to be other than what it says – an authorization for Congress to regulate commerce.” See also the analysis of Justice Scalia's contribution in Day, D., “The Rehnquist Court and the Dormant Commerce Clause: The Unsettling of ‘Well Settled Principles’” (1990–1) 22 U. Tol. L. Rev. 675Google Scholar. Chief Justice Rehnquist himself has also shown some support for their concerns: Kassel v. Consolidated Freightways 450 US 662, 689–90 (1981), considered below n.92.

⁶⁵ J. Larsen, “Discrimination in the Dormant Commerce Clause” (2003–4) 49 S. D. L. Rev. 844, 859 suggests that there might be a third category – purposeful discrimination (i.e. the situation where the purpose behind the statute is discriminatory, citing Kassel v. Consolidated Freightways Corp. 450 US 662, 678–79 although cf. discussion below at n.92ff but she admits that it is less used because it is difficult to find evidence of purpose or motive.

⁶⁶ Hughes v. Oklahoma, 441 US 322, 337 (1979), 337. Discrimination under the dormant commerce clause nevertheless attracts a less demanding strict scrutiny test than under the Equal Protection and Due Process doctrines: Grutter v. Bollinger 123 S.Ct 2325, 2336 (2003) (equal protection) and Reno v. Flores 507 US 292, 302 (1993) (due process) both of which require a “compelling state interest” and that the statute be “narrowly tailored” to promote that government interest: J. Larsen, above n.65, 850.

⁶⁷ Both limbs are required: City of Philadelphia v. New Jersey, 437 US 617, 626 (1978) because “the evil of protectionism can reside in legislative means as well as legislative ends”.

⁶⁹ One, possibly the only, example is Maine v. Taylor 477 US 131 (1986) where the Supreme Court upheld a law which prohibited the import of live baitfish to protect the state's waters from foreign species and parasites which may have affected the native population. As with the ECJ in Case C-67/97 Bluhme [1998] E.C.R I-8033, the Supreme Court upheld the state interest in protecting the environment from non-native species as legitimate and found no less discriminatory alternatives (but cf. Stevens J's dissent).

⁷⁰ West Lynn Creamery Inc v. Healy, 512 US 186, 192 (1984) “state statutes that clearly discriminate against interstate commerce are routinely struck down … unless discrimination is demonstrably justified by a valid factor unrelated to economic protectionism”.

⁷¹ Oregon Waste Systems Inc v. Dept of Environmental Quality, 511 US 93, 99 (1994) “if a restriction on commerce is discriminatory, it is virtually per se invalid”, repeated more recently in Granholm v. Heald 544 US 460, 476 (2005).

⁷² Wyoming v. Oklahoma 502 US 437, 454–5 (1992). See O'Grady, above n.55, 571 who strongly advocates a protectionist reading of the dormant commerce clause rather than a discriminatory one. See also C. Hilson, “Discrimination in Community Free Movement Law” (1999) 24 E.L. Rev. 445.

⁷³ Dean Milk v Madison 340 US 349 (1951). See also Wyoming v. Oklahoma 502 US 437 requiring Oklahoma coal fired electric generating plants producing power for sale in Oklahoma to burn a mix of coal containing at least 10% Oklahoma mined coal. The US Supreme Court said the Act discriminated both on its face and practical effect and could not be justified.

⁷⁵ Emphasis added. In respect of taxation cases, the Supreme Court in Complete Auto Transit v. Brady 430 US 274 (1977) laid down a four pronged test to evaluate state taxes (at p.279): the Court will “sustain a tax against Commerce clause challenge when the tax [1] is applied to an activity with a substantial nexus with the taxing state, [2] is fairly apportioned, [3] does not discriminate against interstate commerce, and [4] is fairly related to the services provided by the State”.

⁷⁸ The facts of Pike do not seem to support a finding of non-discrimination: Arizona state officials could refuse to allow fruit and vegetables to be taken out of the state for packaging. However, the outcome of unconstitutionality would have been the same in the EU: the Supreme Court found that the state interest in preserving the reputation of local products by ensuring they were not sold in substandard packaging was “minimal at best” and was outweighed by the burden on inter-state commerce.

⁷⁹ Regan, D., “The Supreme Court and State Protectionism: Making Sense of the Dormant Commerce Clause” (1985) 84 Mich. L. Rev. 1091CrossRefGoogle Scholar. He argues that the Court rightly has been exclusively concerned with preventing states from engaging in purposeful economic protectionism, which he defines to mean (1) the statute was adopted for the purpose of improving the competitive position of local economic actors, just because they are local, vis-à-vis their foreign competitors; and (2) the statute is analogous in form to the traditional instruments of protectionism (the tariff, quota or embargo).

⁸³ It used to be thought that the mandatory requirements and Art. 30 derogations operated differently. If a national measure could be justified by a mandatory requirement then it did not breach Art. 28. This comes closer to a genuine balancing. If, on the other hand, the national measures could not be justified then there was a breach of Art. 28 and the Member State could in principle have recourse to the derogations in Art. 30 (see, e.g. Case 25/88 Criminal Proceedings against Bouchara [1989] E.C.R 1105, para. [11], and Case 298/87 Smanor [1988] E.C.R 4489, para. [15]). However, the Court no longer makes the distinction between mandatory requirements and Art. 30 derogations, simply saying that once a breach can be established, the national measure can be justified under both Art. 30 and the mandatory requirements (see e.g. Joined Cases C-34-36/95 De Agostini [1997] E.C.R I-3843, para.45).

Midwesco Enterprises 486 US 888, 897 (1988) he said “the scale analogy is not really appropriate, since the interests on both sides are incommensurate. It is more like judging whether a particular line is longer than a particular rock is heavy”. All he would require is that “the state regulation does not facially discriminate against inter-state commerce”: American Trucking Associations Inc v. Scheiner 483 US 266, 304.

¹⁰² Case C-442/02 Caixa-Bank v. Ministère de l'Économie, des Finances et de l'Industrie [2004] E.C.R. I-8961, para. [63].

¹⁰³ See e.g. Article 39(2) provides that freedom of movement of workers “shall entail the abolition of any discrimination based on nationality between workers of the Member States”; Article 43(2) talks of freedom of establishment which occurs “under the conditions laid down for its own nationals by the law of the country where such establishment is effected”; Article 50(2) provides that the person providing a service may temporarily pursue his activity in the host state “under the same conditions as are imposed by the State on its own nationals”. In the field of tax, Art. 90(1) is also drafted in the language of discrimination: “No Member State shall impose, directly or indirectly, on the products of other Member States any internal taxation of any kind in excess of that imposed directly or indirectly on similar domestic products.”

¹⁰⁴ Case C-76/90 [1991] E.C.R I-4221, para. [12], emphasis added.

¹⁰⁵ The “restriction” or “obstacle” language is also reflected in the Treaty e.g. Articles 43 and 49 EC and the original Article 67 EEC talk not only of discrimination but of the progressive abolition of “restrictions” on free movement. Further, Article 3(c) EEC referred to “the abolition, as between Member States, of obstacles to freedom of movement for persons services and capital”. The language of restrictions also pervades the free movement of goods. Articles 28 and 29 EC prohibit “Quantitative restrictions” on imports and exports and all measures having equivalent effect. Unlike the Treaty provisions on persons and capital, no reference is made to discrimination in these Treaty provisions.

¹³⁷ Para. [96]. To emphasize the point, the Court said that inasmuch as all new jobs are subject to a recruitment procedure, the requirement of passing a recruitment competition could not “in itself be liable to dissuade candidates who have already sat a similar competition in another Member State from exercising their right to freedom of movement as workers” (para. [97]).

¹³⁹ Para. [64]. It was also unsuccessfully argued in Deliège that judo was not an economic activity and so Community law did not apply. This argument has successfully been used in the past to exclude the application of Community law: Case 344/87 Bettray v. Staatssecretaris van Justitie [1989] E.C.R 1621, para. [17].

¹⁴⁰ Case C-190/98 Graf v. Filzmozer Maschinenbau GmbH [2000] E.C.R I-493. See C. Costello, “Market Access All Areas – the Treatment of Non-discriminatory Barriers to the Free Movement of Workers” (2000) 29 L.I.E.I. 267.

¹⁴¹ Para. [25]. The Court applied the same test in Joined Cases C-418/93 to C-421/93 and C-460/93-C-464/93, C-9/94 to C-15/94, Semeraro Casa Uno Srl and others [1996] E.C.R I-1683, para. [32] concerning Art. 43. In Case C-212/06 Government of the French Community and Walloon Government v. Flemish Government [2008] E.C.R I-1683 AG Sharpston supported this approach (paras. [55–6]): “A national measure can potentially constitute a prohibited obstacle even if it is non-discriminatory. However, in order actually to constitute an obstacle, such provision must affect access of workers to the labour market and their effect on freedom of movement must not be too indirect and uncertain.” On the facts, the Court found that the restrictive effects of the Flemish legislation – which confined affiliation to a care insurance scheme to those residing in the Dutch speaking region of Belgium and the bilingual speaking region of Brussels – were not “too indirect and uncertain for it to be impossible to regard that legislation as constituting an obstacle contrary to Articles 43 and 49” (para. [51]).

¹⁴² The Court particularly uses the term “restrictions” in the establishment cases (e.g. Case C-250/95 Futura Participations SA [1997] E.C.R I-2471; Case C-446/03 Marks & Spencer's v. Halsey [2005] E.C.R I-10837, para. [34]) and the services cases (e.g. Case C-255/04 Commission v. France (performing artists) [2006] E.C.R I-5251, para. [38]). This reflects the language of the relevant Treaty provisions.

¹⁴³ The term “restrictions” or “obstacles” are synonymous: see e.g. Joined Cases C-388/04, C-359/04 and C-360/04 Placanica [2007] E.C.R. I-1891, para. [43]: “the restrictions imposed on intermediaries … constitute obstacles to the freedom of establishment”. See also E. Johnson and O‘Keeffe, D., “From Discrimination to Obstacles to Free Movement: Recent Developments Concerning the Free Movement of Workers 1989–1994” (1994) 31 C.M.L.Rev. 1313Google Scholar.

¹⁴⁴ A further disadvantage with the language of market access is that it risks downplaying the fact that rules which interfere with the exercise of a free movement right can have just as serious a consequence on free movement as the initial refusal of access, a fact the Court itself has recognized Case 197/84 Steinhauser v. City of Biarritz [1985] E.C.R. 1819. The Services Directive 2006/123 (OJ [2006] L376/26) addresses this problem by explicitly stating that the Directive applies to “requirements which affect access to or the exercise of a service activity” (9th Recital)).

¹⁴⁵ See e.g. Case C-60/00 Carpenter [2002] E.C.R. I-6279.

¹⁴⁹ Para. [39] (emphasis in the original) criticising, in particular, Case C-255/97 Pfeiffer Grosshandel [1999] E.C.R. I-2835.

¹⁵⁰ Para. [62]. The Court itself acknowledged this in Case C-290/04 FKP Scorpio [2006] E.C.R. I-9461, [46] “the application of the host Member State's national rules to providers of services is liable to prohibit, impede or render less attractive the provision of services to the extent that it involves expense and additional administrative and economic burdens”.

¹⁵¹ For criticism of the paucity of the Court's market access analysis, see Spaventa, E., Case note on Case C-442/02 Caixa-Bank (2005) 42 C.M.L.R. 1151Google Scholar. Cf. G. Davies, Nationality Discrimination in the European Internal Market (The Hague 2003), 96–98 on the differences between the types of litigants in free movement and competition cases which necessitates a different approach to proof.

¹⁵² Case C-415/93 Bosman [1995] E.C.R I-4921, para. [103].

¹⁵³ See e.g. Case C-49/89 Corsica Ferries [1989] E.C.R. I-4441, para. [8]: “the articles of the EEC Treaty concerning the free movement of goods, persons, services and capital are fundamental Community provisions and any restriction, even minor, of that freedom is prohibited”.

¹⁵⁴ Eg, Advocate General Cosmas said in Case C-134/94 Esso Española SA v. Comunidad Autónoma de Canarias [1995] E.C.R I-4223, para. [24] that there needs to be a “foreseeable restrictive effect on intra-Community trade” to breach Article 28. In the British courts, Walker LJ, as he then was, talked in R. (on the application of Professional Contractors Group Ltd) v. Inland Revenue Commissioners [2002] 1 C.M.L.R. 46 of a “direct and demonstrable inhibiting effect on the particular right which is asserted”. He recognised that there was a need for some minimum standard otherwise “the UK Government would be in breach because of the poor state of this country's public transport infrastructure”.

¹⁵⁵ There might be hints in the Court's case law that there is a sea-change in its approach. In Case C-353/06 Grunkin-Paul [2008] E.C.R I-000, paras. [23], [24] and [29] the Court talked of the “serious inconvenience” caused by a discrepancy in surnames which created an obstacle to free movement of citizens under Article 18(1). In Case C-110/05 Commission v. Italy (Trailers) [2009] E.C.R I-000, para. [56] the Court referred to the “considerable influence” that a prohibition on the use of a product has on the behaviour of consumers and in Case C-518/06 Commission v. Italy (motor insurance) [2009] E.C.R I-000, para. [66] the Court said that an obligation to contract constitutes a “substantial interference in the freedom of contract”. In the context of positive integration, the Court has explicitly referred to a threshold criteria: Case C-376/98 Germany v. Parliament and Council [2000] E.C.R. I-8419, para. [107] “to interpret Articles 100a, 57(2) and 66 of the treaty as meaning that the Community legislature may rely on those articles with a view to eliminating the smallest distortions of competition would be incompatible with the principle … that the powers of the Community are those specifically conferred on it”. See also H. Toner, “Non-discriminatory Obstacles to the Exercise of Treaty Rights – Articles 39, 43, 49, and 18 EC” (2004) 23 Y.E.L. 275, 285–6 who argues that there are two possible thresholds: direct or significant. If the obstacle is direct then its effect needs only be perceptible; if the measure is significant or substantial then the obstacle does not need to be direct.

¹⁵⁶ According to the orthodoxy, distinctly applicable rules breach the Treaty and can be saved only by the express derogations in the Treaty, and not the judicially developed mandatory (or public interest) requirements (Case 113/80 Commission v. Ireland (Irish souvenirs) [1981] E.C.R. 1625, para. [11]; Case 177/83 Ringelhan [1984] E.C.R. 3651, para. [19]) although this position is now changing (see e.g. Case C-54/05 Commission v. Finland [2007] E.C.R. I-2473 the Court permitted a Finnish requirement of import licences for vehicles, traditionally a distinctly applicable measure, to be justified by a road safety mandatory requirement).

¹⁸³ The Directive contains a number of specific screening duties for the Member States, as well as professional bodies, organisations and associations: (1) to review their authorisation schemes under Article 9(1); (2) to identify and remove the prohibited requirements under Article 14; (3) to evaluate the requirements under Articles 15 and 16; (4) to screen national requirements restricting service recipients under Article 19; (5) to screen national legislation under Article 24 to remove any bans on commercial communications by regulated professions and justify any restriction as to content and conditions of advertising or adapt them where necessary; (6) to remove restrictions on multidisciplinary activities except in certain circumstances, justify those that remain and assess whether those that remain could be replaced by less restrictive means (Article 25).

¹⁸⁴ Other areas of law, particularly in the field of free movement of goods would also benefit from such an approach, as the Commission has now recognised in its documentation on a Single Market for the 21^st century: Commission Staff Working document, “Instruments for a modernised single market policy” SEC (2007) 1518, 25.

¹⁸⁹ Para. [17]. Some commentators suggest that the Court engaged in a similar kind of balancing in Case C-379/98 PreussenElektra v. Schleswag [2001] E.C.R. I-2099, this time in the context of a discriminatory rule: Johnston, A., Neuhoff, K., Fouquet, D., Ragwitz, M. and Resch, G., “The Proposed New EU Renewables Directive: Interpretation, Problems and Perspectives” (2008) 1 European Energy and Environmental Law Review 126, 134Google Scholar.

¹⁹⁰ See e.g. Joined Case C-69 & 258/93 Punto Casa SpA v. Sindaco del Commune di Capena and others [1994] E.C.R. I-2355. Arguably, the US Supreme Court also does not engage in balancing in Keck style situations: Exxon Corporation v. Governor of Maryland 437 US 117, 127–8: ban on petrol producers from operating petrol stations in Maryland was found to be non-discriminatory and not to burden commerce.

¹⁹¹ See the observation by Chief Justice Roberts in United Haulers Association v. Oneida-Herkimer Solid Waste Management Authority 127 S.Ct 1786 (2007) who noted that “The Commerce Clause does not elevate free trade above all other values” (at 1795–6).

¹⁹² For a discussion of this term, see C. Joerges and F. Rödl, “‘Social Market Economy’ as Europe's Social Model?”, EUI Working Paper LAW No 2004/8, 19, who argue that “this concept contained an ordoliberal basis which was complemented by social and societal policies, whose aims and instruments were supposed to rely on market mechanisms”.

¹⁹⁴ See F. Scharpf, “Democratic Legitimacy under Conditions of Regulatory Competition: Why Europe differs from the US” in R. Howse and K. Nicolaides, The Federal Vision, (Oxford 2001), 356–7, noting that in the EU, the creation of the internal market succeeded, rather than preceded, the creation of welfare states. By contrast, in the US, the situation was reversed: the creation of the internal market preceded and thus largely precluded the development of a welfare state since regulatory competition among state governments practically prevented all of them from adopting regulations, such as those prohibiting the employment of child labour, that would have reduced the competitiveness of the local product. In the US, competence in welfare matters was subsequently transferred to the federal level following the New Deal.
