The law of the EU has gained a growing amount of academic attention, especially since the UK decided to leave the union. Concerns are growing about how EU law will continue to impact the UK constitution.
Not only has EU law overlapped significantly with the constitutional and administrative law of England and Wales, but it has also significantly impacted almost every aspect of life in the UK. As the examples of prospective dissertation titles below indicate, there is plenty of room for an excellent law dissertation.
EU Law Dissertation Topics With Research Aims
Topic 1: Legal Study on the Role of the EU in Regulating AI-Based Decision-Making in Public Administration
Research Aim: This study aims to explore how EU law is shaping the use of artificial intelligence in government decision-making. It will assess whether current rules protect people from unfair automated decisions and examine how legal reforms can ensure accountability, transparency, and human rights in AI-powered public services.
Topic 2: The Impact of EU Environmental Law on National Climate Litigation Efforts
Research Aim: This research investigates how EU environmental rules help or hinder individuals and organisations in suing their governments over climate inaction. It aims to see whether EU law gives enough legal tools for people to hold states accountable for climate commitments through the courts.
Topic 3: Comparative Analysis of Digital Sovereignty in EU Data Law and Its Effect on Transatlantic Data Transfers
Research Aim: This dissertation aims to understand how EU efforts to control and protect personal data are affecting data-sharing deals with countries like the US. It will compare legal approaches and highlight where tensions exist between privacy, economic interests, and international cooperation on digital policy.
Topic 4: Preliminary References Decided by the General Court: Has the Transfer of Jurisdiction Protected the Unity of EU Law?
Research Aim: This study will examine the transfer of preliminary reference jurisdiction in six specific areas, including VAT, customs and passenger rights, from the Court of Justice to the General Court.
Analysing the first rulings and the review procedure, it will assess effects on consistency, speed and the Court of Justice’s workload.
Topic 5: Investor Citizenship and the Limits of National Competence After Commission v Malta
Research Aim: This study will analyse the Court of Justice’s ruling that Malta’s investor citizenship scheme breached EU law, examining how far Member States’ power to grant nationality is limited by sincere cooperation and the nature of EU citizenship.
It will consider the implications for residence-by-investment schemes.
Topic 6: Below-Threshold Merger Control After Illumina v Commission: Can National Call-In Powers Fill the Gap?
Research Aim: This study will examine the Court of Justice’s ruling that the Commission cannot accept merger referrals from Member States that lack jurisdiction under their own law, and responses through national call-in powers and the Digital Markets Act’s duty to inform.
It will assess whether killer acquisitions can still be reviewed.
Topic 7: Is Article 122 TFEU a Proper Legal Basis for EU Defence Loans? The SAFE Regulation and Parliament’s Role
Research Aim: This study will examine the use of the emergency economic powers in Article 122 TFEU to adopt the SAFE Regulation, which offers Member States loans for defence procurement through a Council procedure that excludes the European Parliament.
It will assess the limits of emergency legal bases in EU constitutional law.
Topic 8: Departing From Assimilated EU Case Law: How UK Appeal Courts Use Their Power After the Retained EU Law Reforms
Research Aim: This study will analyse how UK appeal courts have used the wider power to depart from assimilated EU case law introduced by the Retained EU Law (Revocation and Reform) Act, which also renamed retained EU law as assimilated law.
It will assess legal certainty and divergence from the Court of Justice.

Frequently Asked Questions
Start with the Court of Justice’s case law on CURIA and new legislation on EUR-Lex, and look for a ruling or regulation that raises an unresolved question about competence, rights or remedies.
Then narrow your idea to one legal instrument or line of cases and one clear question, for example whether a test is applied consistently.
Yes. EU law shapes trade with the UK’s largest partner, applies in Northern Ireland under the Windsor Framework, and survives in UK law as assimilated law.
Many UK law schools still teach it, and its institutions, case law and regulatory models are widely used in comparative work.
Assimilated law is the name now given to the body of law that was retained EU law in the UK after Brexit.
Under the Retained EU Law (Revocation and Reform) Act, the supremacy of EU law and the general principles of EU law no longer apply to it, and UK courts have more freedom to depart from EU case law.
Most EU law dissertations are doctrinal, analysing the Treaties, regulations, directives and judgments of the Court of Justice. Comparative work on how Member States implement a directive is also common.
Empirical projects can use infringement data, preliminary reference statistics or the Commission’s published decisions.
LLM topics usually test a doctrine against new case law or legislation, such as horizontal effect of the Charter, abuse of dominance after Intel, standing to challenge EU acts or the legal basis of new EU powers.
Choose a question narrow enough to analyse the leading judgments in depth.
