The opinion endorses the aims of the future law as regards guaranteeing market unity, though it deems that such unity should not mean uniformity, as the Constitutional Court has stated. Thus a balance must be sought to make nationwide economic unity compatible with the juridical diversity arising from Spain's system of autonomous regions. The Council considers that the bill may be hard to apply and may give rise to litigation between the various spheres of government. It supports a harmonisation of legislation across the various spheres of government, but it believes that such harmonisation should not entail just a standardised bare minimum or a lack of legislation. Unlike the government, the Council believes that bill's implementation will result in extra public spending, so such expenses should be calculated.The Economic and Social Council's plenary session adopted by a majority vote its opinion on the Draft Bill for Guaranteeing Market Unity, submitted by the Economy and Competitiveness Ministry on 15 March for mandatory consultation. The Council agrees with the future law's purpose of ensuring market unity by removing distortions and overlaps which in practice unjustifiably discourage business initiative and job creation. In previous documents the Council has advocated the removal of such distortions in the internal market involving differing costs for companies according to their location, and a check on growth. The Council considers, however, that such unity, as the Constitutional Court has stated, should not entail uniformity, as the configuration of the Spanish State involves a diversity of legal systems. Accordingly the opinion asserts that a balance should be sought so as to allow for plural and diverse measures and regulations across Spain's regions in the economic sphere.As to the contents of the bill, the Council considers that it may be hard to apply and may give rise to litigation given that it affects a large number of regional and local competences, and not only between central and regional governments but also between regional governments themselves and local authorities, as the regulations in the economic operator's region of origin are to take precedence.The Council is in favour of a harmonisation of economic regulations across the various spheres of government, while respecting their various spheres of competence, so as to limit the undue multiplicity of legislation, simplify procedures and remove overlaps and unnecessary requirements as well as unjustified or disproportionate impediments or restrictions. In this respect the Council sees a need to review the legislation enacted by regional and local authorities directly or indirectly entailing discriminatory treatment for companies from other regions. But the Council considers that the bill opts for a legislative alignment that may result in a convergence with a bare minimum or absence of legislation, which the Council cannot endorse. Moreover, enshrining the region-of-origin principle in the order of regulatory precedence may encourage companies to relocate in regions with less regulation, or regulations that favour their business. The opinion warns of the many grey areas in the bill's text which may generate legal insecurity. For example the Council would prefer a clearer definition of the bill's scope, determining the economic sectors and activities affected. The same applies to the penalty procedure, which generates uncertainties where the regulations of the location where a service is provided differ from those of the firm's location of origin. The Council also calls for greater precision regarding the procedures involved in applying for, monitoring and verifying statements of regulatory compliance.The Council also asks that, given the importance of the aim of guaranteeing market unity, explicit account be taken of the need for the economic and social partners to participate in the process and that the bill's articles should include some reference to the future law's implications for consumers.Finally the opinion expresses scepticism at the assertion in the bill's impact analysis that its implementation will not involve extra costs. Accordingly the Council considers that its budgetary repercussions should be properly calculated.
