Part I — Situation overview

The case around Budapest district park-maintenance procurements entered a new phase in June 2026. In early June the Central Investigating Prosecutor’s Office (Központi Nyomozó Főügyészség) took several well-known politicians into custody and named a total of 32 suspects in the case tied to capital-city park-maintenance contracts; the suspicion is that the leader of the central network of companies bribed municipal leaders — regardless of political side — between 2011 and 2024 to obtain and retain contracts, with the alleged bribe sum exceeding 2 billion forints (Central Investigating Prosecutor’s Office statement; HVG, 21 June 2026). On 22 June several outlets uncovered two new threads of the case. Telex and 444.hu showed that District XIII, just a few weeks before the wave of arrests, concluded a three-year, nine-billion-forint framework contract with one of the companies of the implicated group; HVG meanwhile — following Magyar Narancs — examined District XII, Hegyvidék, where during Pokorni Zoltán’s mayoralty the same circle of companies won tender after tender.

It must be stressed: this is an ongoing investigation, and those involved are entitled to the presumption of innocence. What stands as fact today are the confirmed procedural steps — the fact of the suspicions, the arrests and the concluded contracts —, while the content of the confessions can be cited without qualification, attributed to its source. One cooperating entrepreneur in the case, referred to by the press as Z. Zsolt, testified in hopes of a plea bargain that between 2016 and 2023 he paid out more than 600 million forints to the politician referred to as “Pék”, claiming that he received no specific new procurements in return (Telex, 22 June 2026). The credibility of this confession — as the report itself records — will be for the court to weigh.

In MIAK’s reading the character of the scandal is not a question of party affiliation but of structure. The cases that have emerged concern a municipality of left-wing background (District XIII) and of right-wing precedent (District XII, the Pokorni era) alike, and in both the same pattern recurs: narrow competition, a returning winner, the difficulty of comparing prices. The problem is therefore the lack of competition in municipal public procurement and the weakness of the control institutions — this is what must be remedied, regardless of which district and which political side it surfaces in.

Part II — Literature foundation

Before turning to MIAK’s concrete proposals, it is worth fixing the scholarly frame in which the topic can be interpreted. The American economist Robert Klitgaard, a former professor at the Harvard Kennedy School, in his classic Controlling Corruption (1988) set up the C = M + D − A formula: corruption (Corruption) flourishes where monopoly position (Monopoly) and discretionary power (Discretion) meet the lack of accountability (Accountability) — recurring single-bid public procurement produces exactly this trio. Susan Rose-Ackerman, a professor at Yale University, in her work Corruption and Government (1999) devotes a standalone chapter to procurement reform, and argues that the breadth of discretion increases the corruption incentive, while market reference prices (benchmark) and robust competition push it back. The World Bank foundational study Governance Matters (1999) by Daniel Kaufmann and his co-authors — the methodological basis of the Worldwide Governance Indicators (WGI) — demonstrates empirically that better governance, including the control of corruption, stands in a strong causal relationship with better development outcomes. The detailed literature treatment — by author, with quotations — can be found in the 6.4 Literature in detail section.

Part III — MIAK’s concrete proposal

MIAK proposes three measurable measures, each of which targets the restoration of competition and the strengthening of control — with a party-neutral standard, at every municipal level.

3.1 Mandatory open procurement database and anomaly flagging (within 12 months)

MIAK proposes that every municipal public procurement contract — framework amount, winner, bidders, the grounds for invalidations — appear in a machine-readable, public database with real-time updating. On top of this would sit an artificial-intelligence-based anomaly detector that flags single-bid procedures, pricing strongly diverging from the benchmark price, and recurring winner–contractor pairs. The system does not pass judgement, it only marks risk levels; investigation remains a human task. In the Klitgaard C = M + D − A framework (see 6.4.1) this directly strengthens the A, the accountability factor, and through publicity reduces the hidden room for manoeuvre of D, discretionary power. The proposal builds on MIAK’s A2 procurement transparency and A1 public-money dashboard programme points.

3.2 Competitive pressure on municipal tenders (within 18 months)

MIAK proposes that the share of single-bid municipal procedures fall along mandatory target values, and that the grounds for invalidation on account of an “unrealistically low price” be substantiated in every case in a detailed, public document. In District XIII’s tender this year the bid of the sole competitor, Jánosik és Társai Kft., was invalidated partly on administrative grounds, partly because of a disproportionately low price — for some items the report recorded a price difference of more than fiftyfold (444.hu, 22 June 2026). Rose-Ackerman (see 6.4.2) emphasises precisely that the retreat of competition is the breeding ground of overpricing, which is why the mandatory application of market reference prices (benchmark) and the prohibition of slicing (small tenders kept below the open-procedure threshold) are meaningful protection. On the pattern of KI3 measurable bureaucracy reduction, the proposal would also prescribe a public, quantified annual report on the competition indicators.

3.3 Municipal integrity officer and retrospective audits (within 24 months)

MIAK proposes that every larger municipality operate an independent integrity officer, whose remit extends to the rotation of officials working in the risk areas — especially in public procurement — and to the retrospective, independent audit of concluded contracts. In Hegyvidék the current mayor, Kovács Gergely, drew the prosecution’s attention to the fact that for the same tasks the new municipality received offers nearly 40 percent cheaper than in the earlier period (HVG, 21 June 2026) — this is exactly the kind of retrospective comparison an integrity officer would carry out at the system level. The proposal carries the logic of KI7 official rotation and A8 cohesion accountability (100% project verification, a clawback mechanism) over to the local level.

The common principle of the three proposals can be summed up in a single sentence: competition and publicity are the most effective anti-corruption instrument. By Klitgaard’s formula, increasing accountability and narrowing the room for discretion together reduce the structural conditions of corruption — MIAK’s measures move all three variables in this direction, and moreover by an institutional rather than a person-dependent route.

Part IV — Expected impacts and risks

Dimension Expected impact Risk
Economy Park-maintenance prices move closer to the market benchmark; public-money savings Overly strict control can dampen the appetite to bid, so the unused budget may grow
Society Strengthening public trust; the price-value ratio of local services improves The scandal can feed a generalising “all politicians are corrupt” narrative, which reinforces political apathy
Public administration More transparent, comparable municipal procurement; rotation reduces relational dependencies Administrative extra burden at smaller municipalities; the danger of indicator-optimisation (formal competition with straw-man bids)

The main consideration runs between control and operability. If the single-bid share becomes a metric in itself, contractors can formally generate more bids — this is the “competition on paper, collusion in reality” pattern flagged by both Klitgaard and Rose-Ackerman. This is why MIAK pairs the quantitative target value with a qualitative filter (benchmark price, the obligation to justify an invalidation) and an independent retrospective audit. The package tips to the risk side if the introduction of publicity and anomaly flagging is left out and only the formal competitive pressure remains — in which case the system becomes circumventable. It works if the three elements (transparency, competition, retrospective control) are built up together, reinforcing one another.

Part V — Measurability and summary

5.1 What is worth tracking? (suggested KPIs)

  • The share of single-bid procedures in municipal procurements: the suggested goal is that it fall below 15% within 24 months (the reference value of the A2 programme point).
  • Price-benchmark deviation: park-maintenance unit prices should move on average 5–10% closer to the median of comparable districts.
  • Data coverage: 100% of municipal procurement contracts are accessible with a public, machine-readable data sheet.
  • Integrity institution: at what share of larger municipalities an integrity officer and a regular retrospective audit operate.

These performance indicators (KPIs) are suggested measurement points, not government decisions — they indicate whether it is worth following this direction, and not that MIAK will implement anything.

5.2 Summary

MIAK’s request is simple and party-neutral: let the district park-maintenance case not be the scandal of a single political side but the occasion for a system-level reform of municipal public procurement. From decision-makers MIAK asks for the introduction of the open procurement database, real competitive pressure and the municipal integrity officer; and from the public, that it apply the standard consistently, equally to every district and every party. In this case two of MIAK’s foundational values move above all: transparency — because the lack of competition is made visible and accountable only by machine-readable, public data —, and ideology-free conduct — because the anti-corruption standard is credible only if it is enforced regardless of political side, with the same rigour; without these two values the reform would become a party-political weapon, not an institutional guarantee.

Part VI — Justifications and further sources

6.1 Press framing by spectrum

In the left-liberal band Telex brought two approaches: the domestic report focused on the testimony of the “Pék” thread and its internal contradictions (the entrepreneur allegedly paid without specific consideration), while Telex’s economics section, G7, analysed District XIII’s more than decade-long, multi-tens-of-billions-of-forints contractual relationship with Parkfenntartó Kft. 444.hu highlighted the lack of competition: in this tender there was for the first time another entrant, but it was invalidated. Népszava likewise brought District XIII’s nine-billion contract — here only a title-level reference was available (title-level reference only).

In the public-affairs–economic band HVG — building on Magyar Narancs’s article — took up District XII, Hegyvidék, and presented the procurements of the Pokorni era, as well as the market dominance of the four interlinked capital-city park-maintenance companies (Pannon Park Forest, Parkfenntartó, DeerGarden, ZÖFE). This band made the party-independent framing explicit: the problem concerns a right-led and a left-led district alike.

The governing-party/conservative band did not raise the topic into top focus on this day, so its framing from this band cannot be reconstructed. The missing element of the full spectrum is itself telling: the ideology-free handling of the case requires the equal-standard presentation of every side.

6.2 Facts and data

Datum Value Source
Number of suspects 32 people Central Investigating Prosecutor’s Office (HVG, 21 June 2026)
Alleged bribe (whole case) > 2 billion HUF, 2011–2024 Central Investigating Prosecutor’s Office

Hegyvidék price excess for the same task ~40% more expensive in the Pokorni era HVG, 21 June 2026

The source of the numerical data is in every case the indicated press source or the statement of the investigating authority; the criminal-law qualification of the case is the court’s task.

6.3 Policy aspects

  • Transparency and anti-corruption policy (programme points) — the elements of procurement transparency, the public-money dashboard and cohesion accountability (A1, A2, A8);
  • Public administration and e-government (programme points) — measurable bureaucracy reduction and official rotation (KI3, KI7);
  • Justice (background material) — the procedural guarantees of the ongoing investigation, respect for the presumption of innocence.

6.4 Literature in detail

6.4.1 Robert Klitgaard: Controlling Corruption

Klitgaard derives from the principal–agent–client model that corruption flourishes when the agent is in a monopoly position, has broad discretionary power, and has weak accountability — he condenses this into the famous stylised equation: Corruption = Monopoly + Discretion − Accountability. The book separately analyses the position of the procurement official, where collusion drives up prices and bribery distorts the supposedly independent cost estimate. The recurring, single-bid district park-maintenance contract is, in this frame, a situation where all three factors push toward corruption: a single group of companies dominates the market (monopoly), the discretion over tender drafting and invalidation is broad (discretion), and control is exercised retrospectively and weakly (low accountability). MIAK’s proposals move precisely the two regulable variables — discretion and accountability — by means of publicity and competitive pressure.

6.4.2 Susan Rose-Ackerman: Corruption and Government

Rose-Ackerman treats procurement reform in a standalone chapter, and fixes the basic tension: discretion increases the corruption incentive, yet overly rigid codes can also be harmful. As a solution she shifts the emphasis toward market reference prices — the government should procure where benchmark prices exist, because then the pressure of competition comes from the market, not merely from the formal tender procedure. The author also stresses that scandals often erupt where there is no code, or where the tender committee is overridden by corrupt or self-interested political leadership. In the district case the fiftyfold price difference and the invalidation of the sole competitor highlight precisely the lack of benchmark-based comparability — MIAK’s proposal 3.2 would fill this gap with a mandatory reference price and the obligation to justify.

6.4.3 Kaufmann–Kraay–Zoido-Lobatón: Governance Matters

The World Bank foundational study condenses more than 300 governance indicators into six aggregate clusters — among them the control-of-corruption and the voice-and-accountability measures — and demonstrates the development payoff of better governance on the data of more than 150 countries. In the authors’ formulation:

“Six new aggregate measures capturing various dimensions of governance provide new evidence of a strong causal relationship from better governance to better development outcomes.”

Municipal integrity monitoring and a public procurement database are precisely the local-level application of this measurement logic: what is measurable and public becomes accountable.

6.5 International comparison

The theoretical theses of the books are illustrated by the practice of several countries. In Ukraine’s ProZorro electronic procurement system the share of single-bid procedures fell from 40 percent to 18 percent, with savings of around 2 billion dollars a year — this is a direct model for MIAK’s proposals 3.1 and 3.2. Following the introduction of Slovakia’s e-Zmluvy contract register (the online publication of all state contracts), procurement prices in the transparent categories fell on average by 5–8 percent. Estonia, alongside its digital registry system and strong internal audit, has the lowest irregularity rate for EU funds in the union — this supports the direction of the 3.3 integrity audit.

Transparency and anti-corruption policy

  • A1 — Public-money dashboard
  • A2 — Procurement transparency
  • A8 — Cohesion policy accountability

Public administration and e-government

  • KI3 — Bureaucracy reduction, measurably
  • KI7 — Official selection and rotation system

Proposed new programme point: Municipal integrity officer — for the Public administration and e-government area (to institutionalise local-level procurement oversight and retrospective audit).
