The European Test: Ukraine, Corruption and the Rule of Law

By Matthew Parish

Thursday 27 August 2026

Ukraine’s struggle to become a European state has always involved two wars. The first is being fought with artillery, drones, missiles and infantry against the Russian Federation. The second is quieter, older and in some respects more difficult. It is the struggle to replace the informal networks of patronage, political protection, selective prosecution and corruption inherited from the post-Soviet state with institutions governed by law. The European Union has now made clear that victory in the first struggle cannot substitute for progress in the second.

This is the significance of an increasingly serious dispute between Brussels and the Verkhovna Rada over a package of rule-of-law and anti-corruption legislation. On 19 August 2026 the Rada’s law-enforcement committee recommended that five reform bills should not be placed upon the agenda of the current parliamentary session. Strictly speaking, therefore, Parliament has not voted the measures down. Nevertheless the procedural effect, if the recommendation is allowed to stand, is to prevent them from progressing during the session. The measures concern the jurisdiction of Ukraine’s anti-corruption institutions, reform of the Prosecutor General’s Office and the State Bureau of Investigation and procedural rules that can frustrate high-level corruption prosecutions.

The timing could scarcely be worse. In June 2026 the European Union and Ukraine formally opened negotiations on the “Fundamentals” cluster of the accession process. This is not some peripheral collection of technical regulations about agricultural standards or customs documentation. It encompasses the rule of law, fundamental rights, democratic institutions, public administration reform and the economic criteria upon which the entire accession process ultimately rests.

In other words, Brussels has decided that the question at the heart of Ukrainian membership is straightforward: can power in Ukraine be made subject to law?

That question deserves to be treated seriously rather than reduced to the familiar proposition that Ukraine is “corrupt”. Corruption exists throughout Europe. What distinguishes a functioning rule-of-law state is not the absence of dishonest people but the existence of institutions capable of investigating and prosecuting them irrespective of their political connections.

That is where the five stalled reforms matter.

The first would clarify and expand the jurisdiction of the National Anti-Corruption Bureau of Ukraine — NABU — so that it expressly extends to senior officials within the Presidential Office and the head of the State Bureau of Investigation. The EU’s requirement is broader in principle: NABU and the Specialised Anti-Corruption Prosecutor’s Office, SAPO, should possess jurisdiction covering all high-risk positions. At present there are circumstances in which Presidential Office officials can be investigated, but the absence of comprehensive direct jurisdiction creates gaps and potential obstacles.

This is not a minor drafting question. An anti-corruption institution that can investigate everyone except particular categories of politically sensitive official is not genuinely independent. The whole purpose of NABU is that its investigators should not have to ask themselves whether the person at the other end of an investigation is too close to the centre of political power.

The second reform concerns the Prosecutor General. The proposed legislation would introduce a transparent competitive procedure for selecting the Prosecutor General, including participation by international experts. The EU roadmap calls for a comprehensive review of the appointment and dismissal arrangements for the office, bringing them closer to European practice, together with transparent competition for other senior prosecutorial positions.

This is particularly important in Ukraine because the Prosecutor General occupies an extraordinarily powerful position. In a country in which criminal investigations have historically been capable of becoming instruments of political pressure, control over prosecution is itself a form of political power. An independent prosecutor is therefore not merely an administrative reform. It is part of the constitutional architecture of a democratic state.

The parliamentary committee has suggested that the proposed appointment procedure may be constitutionally problematic. That objection should not simply be dismissed. Ukraine must not replace political interference with arrangements that themselves violate the Constitution. Yet a constitutional objection should lead to careful redrafting — or, where necessary, constitutional reform — rather than indefinite postponement of the underlying European requirement.

The third reform concerns the State Bureau of Investigation, or SBI. The proposal similarly envisages a transparent competition for its leadership involving international experts. The European Union expects the SBI to be reformed in accordance with European best practice. President Volodymyr Zelensky had himself promised an alternative reform proposal earlier in 2026, but according to reporting on the present dispute that alternative legislation has not materialised.

Again the institutional principle is more important than the bureaucratic detail. The bodies that investigate senior state officials must themselves be insulated from those officials. Otherwise an anti-corruption architecture may exist magnificently upon paper while failing whenever an investigation approaches somebody genuinely powerful.

The fourth measure addresses an especially technical but consequential problem in Ukrainian criminal procedure. Amendments introduced in 2017 imposed restrictive time limits upon pre-trial investigations and created circumstances in which criminal cases could be terminated because investigative deadlines had expired. Some elements of this regime were repealed in 2023 but significant problems remain. The EU-Ukraine reform programme specifically calls for removing automatic closure of criminal cases arising from the expiry of pre-trial investigation limits and addressing procedural obstacles that impede high-level corruption prosecutions.

There is a legitimate rule-of-law principle behind limitation periods. Nobody should remain indefinitely subject to unresolved criminal accusations. Prosecutors should investigate efficiently and defendants are entitled to legal certainty. Yet sophisticated corruption investigations are frequently complicated. They may involve shell companies, offshore accounts, procurement chains, electronic communications and evidence located abroad. A procedural regime under which sufficiently complicated corruption can effectively outlive the prosecutor’s clock creates precisely the wrong incentive.

The fifth proposal illustrates the problem still more vividly. It would suspend limitation periods in high-level corruption proceedings where the defendant has been mobilised into the armed forces. The objective is obvious: mobilisation should not become a device by which an accused person can cause the limitation period to expire and thereby escape prosecution. The parliamentary committee has raised concerns about legal certainty under the European Convention on Human Rights.

Once again there is a legal question worthy of serious examination. Ukraine is fighting an existential war and millions of Ukrainians serve in its armed forces. Criminal defendants retain rights even during wartime. Nevertheless it ought surely to be possible to draft legislation protecting those rights without allowing military mobilisation to operate as an accidental immunity from prosecution for high-level corruption.

Behind these five measures lies a wider European reform programme. At the end of 2025 then Deputy Prime Minister for European Integration Taras Kachka and EU Enlargement Commissioner Marta Kos agreed a programme of ten priority reforms. Among other things it called for comprehensive amendments to criminal procedure, removal of obstacles to high-level corruption prosecutions, stronger limitation rules for corruption offences, adoption of an Anti-Corruption Strategy and improvements to internal controls against high-level corruption.

The financial consequences are considerable. Implementation of the reforms is connected not merely with the accession negotiations but also with approximately €2.1 billion in European financial assistance expected at the end of 2026. The European Commission reiterated on 25 August that rule-of-law and anti-corruption reform are essential to accession and that Ukraine has itself undertaken these commitments under the Ukraine Plan.

The EU is therefore not suddenly imposing alien conditions upon Kyiv. Ukraine has negotiated and accepted these commitments.

That distinction matters politically. There is an understandable temptation in wartime Ukraine to portray external demands for institutional reform as European bureaucrats lecturing a country whose citizens are dying in defence of Europe. There is some emotional force in this complaint. Ukraine has endured destruction on a scale no existing EU member state has experienced in generations. Its Parliament operates under martial law, its politicians live beneath the threat of missile attack and the administrative resources of the state are overwhelmingly directed towards survival.

Nevertheless the argument ultimately fails. Ukraine applied to join the European Union; the European Union did not apply to join Ukraine.

Membership entails accepting the institutional principles of the Union. More importantly, the reforms Brussels is demanding are overwhelmingly in the interests of Ukrainians themselves.

A Ukrainian soldier should be entitled to believe that money allocated for his equipment has not disappeared into a procurement scheme. A Ukrainian taxpayer should be entitled to believe that a politically connected businessman cannot telephone the appropriate official and terminate an investigation. A Ukrainian entrepreneur should be able to invest without fearing that prosecutors or investigators will become instruments of commercial competitors. A Ukrainian citizen should be entitled to assume that a senior Presidential official and an ordinary civil servant are subject to the same criminal law.

These are not Brussels values imposed upon Ukraine. They are Ukrainian interests.

There is nevertheless another side to the argument. International participation in Ukrainian appointments cannot become permanent. The repeated resort to foreign experts in selecting judges, prosecutors and anti-corruption officials has been understandable because domestic institutions have historically lacked public confidence. Yet sovereignty ultimately requires Ukrainian institutions capable of policing themselves. International experts can serve as scaffolding while those institutions are constructed. They cannot constitute the building forever.

The objective of European integration must therefore be to create a Ukrainian legal culture sufficiently strong that external supervision becomes unnecessary.

This is why the current parliamentary obstruction is troubling. It risks perpetuating precisely the condition that critics of international involvement complain about. Every time domestic political institutions block credible mechanisms of independent scrutiny, they strengthen the argument that outsiders must remain involved.

There is also a broader danger. Ukraine cannot afford the emergence of a political divide in which patriotism and anti-corruption reform are treated as competing causes. They are complementary. Russia’s political system is characterised by the fusion of wealth, state authority, security services and personal loyalty. Ukraine’s historic achievement since 2014 has been progressively to reject that model.

The Maidan revolutions were not principally revolts about European agricultural regulations or customs harmonisation. They were revolts against arbitrary government — against the proposition that there should be one law for ordinary Ukrainians and another for those with access to political power.

European accession gives institutional expression to that aspiration.

Nor should criticism of the Rada become criticism of Ukraine as a whole. Ukraine possesses an unusually vigorous civil society, investigative media, anti-corruption activists, reformist parliamentarians and increasingly capable independent institutions. The very fact that disputes of this kind become public scandals demonstrates how far Ukraine has travelled from the political culture of the Soviet Union and, increasingly, of contemporary Russia.

Indeed the present controversy has arisen partly because Ukrainian reformers themselves are protesting against the parliamentary decision. The five bills were co-sponsored by reform-oriented deputies including Anastasia Radina, chair of Parliament’s anti-corruption committee, and Yaroslav Zheleznyak. The dispute is therefore not properly described as “Europe versus Ukraine”. It is a contest within Ukraine over what sort of European state Ukraine intends to become.

That contest will continue long after the war.

The uncomfortable truth is that wartime centralisation has advantages. Decisions must be made quickly. Information must sometimes remain secret. Governments fighting for national survival cannot conduct every matter as though they were administering Luxembourg in peacetime. Yet institutions accustomed to extraordinary powers seldom surrender them enthusiastically. The transition from wartime government to ordinary constitutional government may therefore prove one of the most delicate periods in Ukraine’s modern history.

This makes building independent institutions now all the more important.

There is also a hard geopolitical reality behind Brussels’ insistence. European governments are contemplating not merely admitting another member state but integrating a large country emerging from a devastating war, requiring immense reconstruction expenditure and possessing a substantial agricultural, industrial and defence sector. Hundreds of billions of euros of public and private capital may eventually flow into Ukrainian reconstruction.

Without reliable courts, prosecutors and anti-corruption institutions, some proportion of that money will inevitably be lost. More importantly, investors will price corruption risk into every Ukrainian project. Capital will become more expensive, insurance premiums will rise and respectable international companies will hesitate to enter the market.

Rule-of-law reform is therefore economic policy.

It is also national-security policy. Corrupt institutions are vulnerable institutions. Officials who accept bribes can be recruited by foreign intelligence services. Opaque procurement networks provide opportunities for hostile penetration. Politically controlled prosecutors can be used to settle factional disputes at precisely the moment national unity is required. A transparent state is harder for Russia to manipulate.

The European Commission is therefore right to insist upon these reforms, although Brussels should exercise its influence intelligently and with humility. Ukraine is not an applicant state proceeding through the comfortable rituals followed by Austria or Sweden in the 1990s. It is simultaneously fighting the largest European land war since 1945. Deadlines must occasionally recognise reality and European officials should resist the temptation to confuse procedural compliance with genuine institutional transformation.

But the essential conditions cannot be abandoned.

Ukraine’s European destiny will not ultimately be determined by how many EU directives are translated into Ukrainian law. It will be determined by something more fundamental: whether a Ukrainian citizen can stand before the state and insist upon the law even when somebody more powerful would prefer otherwise.

That is what the present five bills are really about.

The Rada should reconsider its decision. Where constitutional or human-rights objections are genuine, the bills should be amended. Where drafting is defective, it should be improved. Where the government has better proposals, it should produce them immediately. What should not happen is that procedural manoeuvres become a means of allowing difficult reforms quietly to expire.

Ukraine has repeatedly declared that its future lies in Europe. Europe is now asking Ukraine to construct the institutions that make that declaration meaningful.

For a country fighting a war over whether it belongs to the political civilisation of democratic Europe or the authoritarian world represented by Moscow, this is not a secondary matter.

It is part of what the war is about.
