Eu Law Supremacy Essay Typer

The primacy of European Union law (sometimes referred to as supremacy) is an EU law principle that when there is conflict between European law and the law of Member States, European law prevails; the norms of national law have to be set aside. This principle was developed by the European Court of Justice, and, as interpreted by that court, it means that any norms of European law always take precedence over any norms of national law, including the constitutions of member states. Although national courts generally accept the principle in practice, most of them disagree with this extreme interpretation and reserve the right, in principle, to review the constitutionality of European law under national constitutional law.[1]


In Costa v. ENEL.[2] Mr Costa was an Italian citizen opposed to the nationalising of energy companies. Because he had shares in a private corporation subsumed by the nationalised company, ENEL, he refused to pay his electricity bill in protest. In the subsequent suit brought to Italian courts by ENEL, he argued that nationalisation infringed EC law on the State distorting the market.[3] The Italian government believed that this was not even an issue that could be complained about by a private individual, since it was a national law decision to make. The European Court of Justice ruled in favour of the government, because the relevant Treaty rule on an undistorted market was one on which the Commission alone could challenge the Italian government. As an individual, Mr Costa had no standing to challenge the decision, because that Treaty provision had no direct effect.[4] But on the logically prior issue of Mr Costa's ability to raise a point of EC law against a national government in legal proceeding before the courts in that member state the ECJ disagreed with the Italian government. It ruled that EC law would not be effective if Mr Costa could not challenge national law on the basis of its alleged incompatibility with EC law.

It follows from all these observations that the law stemming from the treaty, an independent source of law, could not, because of its special and original nature, be overridden by domestic legal provisions, however framed, without being deprived of its character as community law and without the legal basis of the community itself being called into question.[5]

In other cases, countries write the precedence of Union law into their constitutions. For example, the Constitution of Ireland contains a clause that, '"No provision of this Constitution invalidates laws enacted, acts done or measures adopted by the State which are necessitated by the obligations of membership of the European Union or of the Communities...."

  • C-106/77, Simmenthal [1978] ECR 629, duty to set aside provisions of national law which are incompatible with Union law.
  • C-106/89 Marleasing [1991] ECR I-7321, National law must be interpreted and applied, insofar as possible, so as to avoid a conflict with a Community rule.

Article I-6 of the European Constitution stated that "The Constitution and law adopted by the institutions of the Union in exercising competences conferred on it shall have primacy over the law of the Member States." However, the constitution was never ratified but its replacement, the Treaty of Lisbon included the following declaration on primacy:

17. Declaration concerning primacy

The Conference recalls that, in accordance with well settled case law of the Court of Justice of the European Union, the Treaties and the law adopted by the Union on the basis of the Treaties have primacy over the law of Member States, under the conditions laid down by the said case law.
The Conference has also decided to attach as an Annex to this Final Act the Opinion of the Council Legal Service on the primacy of EC law as set out in 11197/07 (JUR 260):

'Opinion of the Council Legal Service
of 22 June 2007
It results from the case-law of the Court of Justice that primacy of EU law is a cornerstone principle of Union law. According to the Court, this principle is inherent to the specific nature of the European Community. At the time of the first judgment of this established case law (Costa/ENEL,15 July 1964, Case 6/641 (1) there was no mention of primacy in the treaty. It is still the case today. The fact that the principle of primacy will not be included in the future treaty shall not in any way change the existence of the principle and the existing case-law of the Court of Justice.

(1) "It follows (...) that the law stemming from the treaty, an independent source of law, could not, because of its special and original nature, be overridden by domestic legal provisions, however framed, without being deprived of its character as Community law and without the legal basis of the Community itself being called into question."'

Declaration 17, Consolidated EU Treaties[6]

Particular countries[edit]

Depending on the constitutional tradition of member states, different solutions have been developed to adapt questions of incompatibility between national law and EU law to one another. Union law is accepted as having supremacy over the law of member states, but not all member states share the ECJ's analysis of why EU law takes precedence over national law when there is a conflict.

Czech Republic[edit]

Article 10 of the Constitution of the Czech Republic states that every international treaty ratified by parliament of the Czech Republic is a part of the Czech legislative order and takes precedence over all other laws.[7]


Like many countries within the civil law legal tradition, France's judicial system is divided between ordinary and administrative courts. While the ordinary accepted the supremacy of EU law in 1975, the administrative only accepted the doctrine in 1990. Before this the supreme administrative court, the Conseil d'Etat, held that as the administrative courts had no power of judicial review over legislation enacted by the French Parliament, they could not find that national legislation was incompatible with EC law or give EC law precedence over conflicting national law. This was in contrast to the supreme court of the ordinary courts, the Cour de cassation, which in the case of Administration des Douanes v Société 'Cafes Jacques Vabre' et SARL Wiegel et Cie,[8] ruled that precedence should be given to EC law over national law in line with the requirements of the Article 55 of the Constitution which accorded supremacy to ratified international treaty over national law. The administrative courts finally changed their position in the case of Raoul Georges Nicolo[9] when they decided to follow the reasoning used by the Cour de cassation.


In Solange II[10] the German Constitutional Court held that so long as (German: solange) EU law had a level of protection of fundamental rights substantially in concurrence with the protections afforded by the German constitution they would not longer review specific Union acts in light of their own constitution.


The Third Amendment of the Constitution of Ireland explicitly provided for the supremacy of EU law within the Republic of Ireland by providing that no other provision of the Irish constitution could invalidate laws enacted which was necessitated by membership of the then European Communities. In Crotty v. An Taoiseach the Irish Supreme Court held that the ratification of the Single European Act by Ireland was not necessitated by membership of the European Communities and could therefore be subject to review by the courts.


In Frontini v. Ministero delle Finanze,[11] the plaintiff sought to have a national law disregarded without having to wait for the Italian constitutional court do so. The ECJ ruled that every national court must apply Community Law in its entirety.


The Lithuanian Constitutional Court concluded with its Ruling dated 14 March 2006 in case no. 17/02-24/02-06/03-22/04, § 9.4 in Chapter III, that EU law has supremacy over ordinary legal acts of the Lithuanian Parliament, but not over the Constitution. In case when the Constitutional Court finds the EU law contrary to the Lithuanian Constitution, the Union law loses its direct effect and shall remain inapplicable.[12]


The Constitutional Tribunal of Poland ruled that while EU law may override national statutes, it does not override the Constitution. In cases of a conflict between EU law and the Constitution, Poland can make a sovereign decision as to how this conflict should be resolved (i.e. by changing the Constitution, leaving the EU or seeking to change the EU law).[13]

United Kingdom[edit]

In R v Secretary of State for Transport, ex p Factortame Ltd, the House of Lords ruled that courts in the United Kingdom had the power to "disapply" acts of parliament where they conflicted with EU law. Lord Bridge held that Parliament had voluntarily accepted this limitation of its sovereignty, being fully aware that, even if the limitation of sovereignty was not inherent in the Treaty of Rome, it had been well established by jurisprudence before Parliament passed the European Communities Act 1972.[14]

If the supremacy within the European Community of Community Law over the national law of member states was not always inherent in the EEC Treaty it was certainly well established in the jurisprudence of the Court of Justice long before the United Kingdom joined the Community. Thus, whatever limitation of its sovereignty Parliament accepted when it enacted the European Communities Act 1972 was entirely voluntary. Under the terms of the 1972 Act it has always been clear that it was the duty of a United Kingdom court, when delivering final judgment, to override any rule of national law found to be in conflict with any directly enforceable rule of Community law.

However, in the 2014 case of R (HS2 Action Alliance Ltd) v Secretary of State for Transport, the UK Supreme Court said:[15][16]

The United Kingdom has no written constitution, but we have a number of constitutional instruments. They include Magna Carta, the Petition of Right 1628, the Bill of Rights and (in Scotland) the Claim of Rights Act 1689, the Act of Settlement 1701 and the Act of Union 1707. The European Communities Act 1972, the Human Rights Act 1998 and the Constitutional Reform Act 2005 may now be added to this list. The common law itself also recognises certain principles as fundamental to the rule of law. It is, putting the point at its lowest, certainly arguable (and it is for United Kingdom law and courts to determine) that there may be fundamental principles, whether contained in other constitutional instruments or recognised at common law, of which Parliament when it enacted the European Communities Act 1972 did not either contemplate or authorise the abrogation.

I never really liked Public Law during my LLB Law degree at the University of Birmingham, so let’s just say my lecturers would be glad to see me taking such a keen interest. I recall writing an essay on Parliamentary Sovereignty. It was last minute and very late in the night, as with most of my first year assignments (well only the ones that didn’t count).


Unlike our distant friends in the United States of America, our constitution (basically a set rules by which we are governed) is by and large unwritten. Which means that there is no existing place, book or building that holds or contains the rules considered to form the UK constitution. This has its pros and cons but is outside the scope of this particular post so if you’d like to know more about that then feel free to get in touch.

Now back to the main topic – there is one fundamental rule of the UK constitution, simply put “Parliament is sovereign”. This is a rule of law that has been around for hundreds of years, but what exactly does this mean and why is it at the centre of the latest development in Brexit?

Essentially, Parliament has the power to make and unmake any law it chooses. If Parliament wants to compensate people for their losses during the 2011 riots it can. In fact it did just that with the Riots Compensation Act 2016 which repealed (replaced) the Riot (damages) Act 1886. Parliament can legislate as it wishes, but let’s not take this too far. Of course there are constraints on this whether written or not. We live in a democratic society where those who govern can be held to account. Acts of Parliament can and have been challenged. What I’m saying is you’re safe, Parliament isn’t going to legislate to send you and your friends to Jupiter in search of aliens, or will it? (Bad example but you get the drift). I bet Paul, Peter and Michael never imagined they’d be forced to go to war in 1916 – Conscription Act 1916.

So now we’ve established and understood what Parliamentary sovereignty is, let’s take it a little further. The Parliament of 1972 (which was sovereign) enacted the European Communities Act 1972 (ECA 1972). This effectively brought the United Kingdom into the European Communities (EC) including the European Economic Community (ECC). Basically, what you and I now know as the European Union. I won’t bore you with the history of what the initial group was for or about. The point is, the ECA 1972 is an act of Parliament, and remember “Only Parliament can make and unmake law”.

But some of you may be thinking, didn’t Theresa May, the British Prime Minister say herself that she was going to give notice pursuant to Article 50? (Essentially begin the exodus from the EU). Well, you’d be right to think that. But here is where it gets interesting. When we say that Parliament is sovereign it means exactly that. The Government of the day (The Conservatives led by Mrs. Theresa May) cannot override legislation enacted by Parliament! Only Parliament can.

There is an exception to this, yes you guessed it, “Prerogative Powers”. Essentially a legal doctrine that has existed longer than Parliamentary Sovereignty. This doctrine provides that the Crown (Our majesty Queen Elizabeth) can act alone where it is deemed that doing so is in the national interest. In reality, they are typically exercised by the executive (the Government). As you’d imagine the Crown rarely interferes with legislative matters. I mean when did you ever hear of the Queen vetoing an Act of Parliament or refusing to swear in the elected Minister as Prime Minister? It just doesn’t happen, mostly because the United Kingdom has changed (the Monarchy is far less significant), but more so because over hundreds of years Parliament has curtailed the powers of the Monarchy – for your and my benefit/interest.

And here is precisely where the latest debate arises for the most part. On the one hand we have Gina Miller & Others (Camp Parliamentary Sovereignty) and on the other hand we have the Secretary of State “The Government” (Camp Prerogative Powers).

Summary of Arguments

Camp Parliamentary Sovereignty: The Crown’s prerogative powers cannot be used by the government of the day to diminish or abrogate rights or laws under the law of the United Kingdom, unless such a right is express within the act in question (ECA 1972). Furthermore, the 2015 Referendum Act did not confer such powers upon the executive. Article 50 TEU (Treaty on European Union) can only be triggered following Parliamentary debate.

Camp Prerogative Powers: The wording of the ECA 1972 does not restrict the Crown from exercising its prerogative powers, nor do any other Acts do so (specifically the European Union (Amendment) Act 2008 and the European Union Act 2011). Either way, the fact that the 2015 Referendum Act is silent on this matter is further evidence to support the contention that Parliament intended for the Crown to be able to rely on its prerogative, to call for the UK to leave the EU without Parliaments involvement.

So what now?

Well, the people have spoken. The referendum result no matter what you and I might think about it, is and was a decision by the UK to leave the EU. The Government has a mandate which it must follow. One of the most fundamental and respected principles in the UK is democracy. It would be undemocratic for Parliament to ignore the decision of the people. That is what you’d call a dictatorship. But then on the other hand would it not be undemocratic for the Government to trigger article 50, without a clear plan that has been rightfully debated by Ministers elected by us to do just that!? They asked for a mandate and they got one, the thing is what’s a mandate with zero terms? On June 25 2016, 51% of the UK decided to leave an establishment that provided certainty for a future with zero certainty. What’s really worrying is that no terms were formally presented, whatever deal we get isn’t going to be one anyone voted for. It’ll be one which the Government wants, or better said what the EU is willing to accept.

For those of you like myself who woke up surprised on June 26 2016, confused and disappointed from the result, there is but an ounce of good news that can come from this. Will Labour block a vote to trigger Article 50? Very unlikely, Shadow Brexit Secretary Sir Keir Starmer has already publicly stated that Labour will not frustrate the process. Although a lack of transparency by the UK has seen Scotland press for more involvement, with fears of a Scottish challenge against the U.K. Government. Nicola Sturgeon and other Scottish representatives have made it clear that this is a real possibility.

Will Parliamentary debate lead to a deal that will see the UK somehow still part of the European Union process? hint hint “the single market ” which will come at a cost. In my opinion, YES. If we’ve learnt anything over the passed 5 months, it’s that a clean and total separation from the EU, is simply put, a bad idea. Those who led the Brexit campaign know this and have since taken a step back from complete separation. Everyone knows it. Scotland desperately wants to ensure that there is access to the single market

Now that there will likely be a debate in Parliament, we the people must take a further step back and observe as the ultimate decision to leave the EU is made by Parliament, by the Ministers that you and I all decided we’re good enough, worthy or whatever you want to call it, to play a role in the governance of the UK.

Government Appeal?

Those who have kept track of the development will note that I have not considered that there may be an appeal to the Supreme Court. You’re right. I haven’t for the simple point that an appeal by the Government will not succeed. Three reasons. Firstly, the High Court respectfully arrived at the correct legal conclusion (D.V Dicey would be ever so proud – a legendary British jurist and constitutional theorist). Secondly, judges like judges and not politicians. And last but by no means least, Parliament is Sovereign, use of Prerogative Powers would constitute a step backwards for democracy. Any likely appeal is likely to happen in December so it may be a Merry “European” Christmas or this could mark the beginning of something new.
