This contribution places the provisions of the Treaty creating a free trade area and customs union between the Member States (Articles 28-31 TFEU) in their wider context. It then focuses on the interpretation of Article 30 in the jurisprudence of the Court of Justice of the European Union (CJEU). Throughout, it casts sideways glances at corresponding provisions of General Agreement on Tariffs and Trade (GATT). As it turns out, the abolition of customs duties and charges having equivalent effect, and the establishment of a customs union between Member States, were important milestones in the development of European unification. They became overshadowed later by more spectacular developments in the case law on the free movement of goods, persons and services. As a consequence, the importance of the customs provisions is widely underrated. Brexit concentrates the minds in this respect, as an important economy is about to rearrange and even recreate the basic building blocks of its international trading relations.

In this contribution the author examines how, from a customs perspective, the integrity of the internal market is protected after the transitional phase under the Revised Protocol on Ireland/Northern Ireland. He briefly discusses the customs aspects of the Withdrawal Agreement and then examines in depth the revised arrangement with regard to the Irish border in light of the protection of the integrity of the internal market. He shows that the revised arrangement cleared the Brexit deal through parliament and paved the UK’s way to leave the EU on 31 January 2020. He concludes, however, that given the complexity of the legislation underlying the revised arrangement, the UK will be paying a high price for getting Brexit done, keeping the Irish border open and protecting the integrity of the internal market of the EU.

This contribution examines the various international instruments, in both hard and soft law, that have been established by international organisations such as the WTO and WCO and scrutinises how they have been implemented into EU legislation governing the EU Customs Union, thus demonstrating the substantial influence of international instruments on the Customs Union. As the relevant international instruments affect not only the traditional elements of European customs law, but also the EU’s entire export control regime and the framework of the internal market, this contribution demonstrates, moreover, how the Customs Union functions in a globalised world.

This study is focused on the evaluation of successes and failures of the Common Market of the South (Mercosur). This analysis of Mercosur’s integration seeks to identify the reasons why the bloc has stagnated in an incomplete customs union condition, although it was originally created to achieve a common market status. To understand the evolution of Mercosur, the study offers some thoughts about the role of the European Union (EU) as a model for regional integration. Although an EU-style integration has served as a model, it does not necessarily set the standards by which integration can be measured as we analyse other integration efforts. However, the case of Mercosur is emblematic: during its initial years, Mercosur specifically received EU technical assistance to promote integration according to EU-style integration. Its main original goal was to become a common market, but so far, almost thirty years after its creation, it remains an imperfect customs union.
The article demonstrates the extent to which almost thirty years of integration in South America could be considered a failure, which would be one more in a list of previous attempts of integration in Latin America, since the 1960s. Whether it is a failure or not, it is impossible to envisage EU-style economic and political integration in South America in the foreseeable future. So far, member states, including Brazil, which could supposedly become the engine of economic and political integration in South America, have remained sceptical about the possibility of integrating further politically and economically. As member states suffer political and economic turmoil, they have concentrated on domestic recovery before being able to dedicate sufficient time and energy to being at the forefront of integration.

This contribution deals with the latest proposals regarding levying VAT in the European Union (EU) Customs Union. The present system, which has been in place since 1993 and was supposed to be transitional, splits every cross-border transaction into an exempted cross-border supply and a taxable cross-border acquisition. It is like a customs system, but lacks equivalent controls and is therefore the root of cross-border fraud. After many years of unsuccessful attempts, the Commission abandoned the objective of implementing definitive VAT arrangements based on the principle of taxing all cross-border supplies of goods in the Member State of their origin, under the same conditions that apply to domestic trade including VAT rates. The European Parliament and the Council agreed that the definitive system should be based on the principle of taxation in the Member State of the destination of the goods. After a brief discussion of the VAT Action Plan of 2016 (Section 1), the e-commerce package in the form of Directive (EU) 2017/2455 is dealt with (Section 2), followed by the proposal to harmonise and simplify certain rules in the VAT system and introduce the definitive system, only partially adopted (Section 3). Section 4 deals with the proposal to introduce detailed measures of the definitive VAT system. The proposed harmonisation and simplification of certain rules were meant to become applicable on 1 January 2019, but will become only partially applicable on 2020. It is proposed to make the detailed measures of the definitive VAT system applicable in 2022. It remains to be seen whether the Member States are willing to accept the definitive VAT system at all; hence the subtitle ‘the ordeal of indirect tax harmonisation’.
