Abstract. Article 299 of the Polish Criminal Code criminalizes money laundering through one of the most capacious provisions of Polish substantive criminal law: a catalogue of named acts supplemented by a general clause that reaches, at least potentially, almost any disposition of assets of suspect provenance. This article reconstructs the statutory architecture of the offense, examines the four cumulative elements of liability, analyzes the leading resolutions of the Supreme Court (I KZP 19/13 and I KZP 5/15), and situates the Polish model within the framework of Directive (EU) 2018/1673 and the 2024 European AML package. Particular attention is devoted to the amendment in force since 1 October 2023, which, through Article 306b, elevates laundering involving assets above PLN 5 million to the rank of a felony, with penalties of up to 20 years of imprisonment and, above PLN 10 million, up to 25 years, and to the procedural incident that in practice opens most cases: the blocking of a bank account. It is submitted that although the breadth of the provision reflects a faithful, arguably overzealous, implementation of international standards, adjudication has generated meaningful limiting principles upon which a rational defense can be constructed.
Introduction
A mere suspicion that funds passing through a company account may be connected with somebody else’s crime suffices to draw an entrepreneur into the orbit of the Polish law enforcement apparatus: first as a witness and then, not infrequently by an almost imperceptible transition, as a suspect. The offense in question, defined in Article 299 of the ustawa z dnia 6 czerwca 1997 r. Kodeks karny (Act of 6 June 1997, the Criminal Code; consolidated text: Journal of Laws, Dz.U., of 2025, item 383; hereinafter: CC), carries in its basic form imprisonment from 6 months to 8 years; since 1 October 2023, where the assets involved exceed PLN 10 million, the upper limit rises to 25 years (Article 306b § 2 CC). The pages that follow reconstruct the anatomy of this offense: its genealogy and European context, the elements the prosecution must establish, the circle of potential perpetrators, the sanctions regime, the blocking of accounts that typically announces the proceedings, and, finally, the axes along which contested prosecutions are in practice resolved.
The Money Laundering Offense and Its Genealogy
A. Definition and the Three Phases of Laundering
Money laundering denotes the ensemble of operations designed to confer an appearance of legality upon assets derived from crime. Criminological literature, following the standards of the Financial Action Task Force (FATF), distinguishes three phases: placement, that is, the introduction of illicit funds into the financial system, for instance through fragmented cash deposits; layering, that is, the obliteration of the trail through chains of transfers, changes in the form of assets, including the conversion of fiat currency into cryptoassets, and the commingling of tainted funds with legitimate ones; and integration, when the assets return to circulation bearing a spurious pedigree of legality. For the purposes of criminal liability this sequence is of merely heuristic value: the settled position of the courts is that the perpetrator need not traverse all three phases, a single act enumerated in the provision being sufficient (judgment of the Supreme Court of 28 February 2023, V KK 629/21). Nor is the popular label entirely accurate. As R. Zawłocki and M. Gałęski observe in the commentary edited by M. Królikowski and R. Zawłocki (5th ed., 2024), the statute in truth criminalizes the laundering of assets at large: alongside means of payment, it embraces financial instruments, securities, foreign exchange values, property rights, movables and immovables.
B. Three Decades of Legislative Expansion
The present shape of Article 299 CC is the product of a consistent widening of the net. The first Polish criminalization, in Article 5 of the ustawa z dnia 12 października 1994 r. o ochronie obrotu gospodarczego (Act on the Protection of Economic Transactions), still required a nexus with organized crime. The 1997 Code abandoned that requirement together with the purposive character of the offense. The amendment of 16 November 2000 removed both the closed catalogue of predicate offenses and the stipulation that the predicate be committed by other persons, thereby opening the door to the liability of the predicate offender for laundering his own proceeds. The amendment of 9 October 2015, implementing recommendations of the Moneyval committee of the Council of Europe, added the acts of possessing, using and concealing as well as transfer and conversion, and introduced punishable preparation (§ 6a). Finally, the Act of 7 July 2022 inserted, with effect from 1 October 2023, Article 306b CC, raising the ceiling of punishment to 25 years. Commentators have argued, not implausibly, that somewhere along this trajectory the critical point of rational criminalization was crossed, since parts of the provision now operate on the basis of pure risk rather than of any demonstrable threat to a protected legal interest. A net with a fine mesh, after all, catches also the fish nobody intended to catch: entrepreneurs who neither knew nor could have known of the provenance of a counterparty’s funds.
C. The European Framework
The Polish provision is an offspring of international obligations: the Council of Europe conventions on the laundering, search, seizure and confiscation of the proceeds from crime, the FATF Recommendations, and successive European directives. The criminal law benchmark is today Directive (EU) 2018/1673 of 23 October 2018 on combating money laundering by criminal law, while the preventive architecture was recast by the 2024 AML package: Regulation (EU) 2024/1624, Regulation (EU) 2024/1620 establishing the new supervisory authority AMLA, and Directive (EU) 2024/1640, with the principal obligations of the package becoming applicable in 2027. It appears worth noting, from a comparative perspective, that Poland follows the model under which any prohibited act may serve as a predicate, an approach broader than the enumerative lists still found in some jurisdictions and fully congruent with the directive’s expansive concept of criminal activity.
The Four Cumulative Elements of Liability
The breadth of the provision does not translate into automatic convictions. Liability under Article 299 § 1 CC presupposes the concurrence of four elements, and the collapse of any one of them entails the collapse of the charge. Intellectual honesty, however, requires beginning each element from the position most favorable to the prosecution, for it is against that position that any defense must ultimately be measured.
A. A Specified Predicate Offense
The prosecution’s hand is stronger than intuition might suggest. No prior conviction for the predicate offense is required; its perpetrator need not be identified, nor his individual liability established; even the prescription of the predicate is irrelevant (judgment of the Supreme Court of 4 October 2011, III KK 28/11, OSNKW 2011, No. 11, item 101). It suffices to describe in the charge conduct fulfilling the elements of a concrete statutory type or, where a precise qualification proves impossible, to establish those elements of the source act from which the fulfillment of the objective elements of a prohibited act indisputably follows (decision of the Supreme Court of 12 March 2018, II KK 371/17, OSNKW 2018, No. 6, item 46).
There, however, the concessions end. The Supreme Court consistently demands the identification of a concrete statutory type from which the proceeds derive: a generic reference to criminal activity, to an undisclosed source, or even to a class of offenses such as tax fraud will not do (thus the operative thesis of the already cited judgment III KK 28/11). Equally inadmissible is the inverted inference that, absent proof of lawful origin, the origin must be criminal; the Court of Appeal in Wrocław rejected that presumption in terms, adding a requirement which indictments tend to overlook: in cases involving several accused, the predicate must be specified with reference to each of them individually (judgment of 7 March 2016, II AKa 242/15). Moreover, the decriminalization of the predicate deprives Article 299 § 1 CC of one of its elements (judgment of the Court of Appeal in Wrocław of 24 July 2019, II AKa 1/19). A failure of specification may prove irreversible for the prosecution: in case III KK 28/11 the description of the act indicated no predicate, and since the judgment had been challenged solely in favor of the convicted person, the indirect prohibition of reformatio in peius (Article 443 of the Code of Criminal Procedure) foreclosed any supplementation of the description and, with it, any conviction for laundering. The spectrum of predicates encountered in practice is wide: from VAT carousel fraud and empty invoices, through classical fraud and the whole field of white collar crime, to investment schemes settled in cryptoassets, where the laundering count now appears almost routinely.
B. Proceeds Direct and Indirect; the Commingling Problem
In a resolution of seven judges entered in the register of legal principles, the Supreme Court held that the object of the offense comprises assets deriving from the prohibited act both directly and indirectly (resolution of 18 December 2013, I KZP 19/13, OSNKW 2014, No. 1, item 1). Laundering thus reaches not only the moneys obtained from the crime itself but also their equivalents and fruits: interest, dividends on shares purchased with stolen funds, real property acquired for sums already several times transformed.
At the same time the Court drew a quantitative boundary for accounts on which lawful and unlawful funds have been commingled: the object of the offense may be the funds held on the account only up to an amount equal to the value of the benefits to which the act of laundering related (resolution of seven judges of 24 June 2015, I KZP 5/15, OSNKW 2015, No. 7, item 55). The balance of the account does not become tainted in toto. This ceiling, which arguably performs the function that tracing doctrines serve in common law systems, matters both for the scope of the charge and for the permissible extent of any blocking or freezing of assets.
C. Mens Rea: Intent as the Principal Battleground
Again the prosecution’s opening position deserves candid statement. Dolus eventualis suffices: it is enough that the perpetrator foresaw the criminal provenance of the assets and reconciled himself to it. He need not know the details of the predicate nor its legal qualification; awareness that the source conduct attracts criminal liability is all the law requires (thus, among others, the judgments of the Court of Appeal in Warsaw of 25 February 2022, II AKa 204/20, and of the Court of Appeal in Szczecin of 12 December 2019, II AKa 256/19). Nor is any purpose of introducing the funds into legal circulation, or of obtaining a financial benefit, an element of the offense (thesis of the judgment V KK 629/21, cited above). In practice intent is proved circumstantially: a price grossly out of line with the market, cash in a trade that settles by transfer, a counterparty without substance or history, a commission for merely passing funds through an account.
The defense, however, retains one hard rule: Article 299 CC knows no negligent variant. Recklessness, carelessness, even a grave error in the appraisal of a counterparty will not sustain a conviction; in this respect the Polish statute is markedly narrower than regimes which extend, in effect, to mere suspicion, as arguably does the United Kingdom Proceeds of Crime Act 2002. If the entrepreneur neither knew of the criminal origin of the funds nor reconciled himself to it, liability fails. The line between “ought to have suspected” and “reconciled himself to” is precisely where most laundering trials are decided, which is why documented counterparty verification and a demonstrable commercial rationale possess an evidentiary value difficult to overstate.
D. The Capacity to Obstruct the Ascertainment of Origin
Here runs the deepest interpretive controversy surrounding Article 299 § 1 CC. In resolution I KZP 5/15 the Supreme Court held that the modal clause, requiring that the conduct be capable of thwarting or significantly hindering the ascertainment of the criminal origin of the assets, qualifies only the residual category of other actions; the named acts, such as acceptance or transfer, would be punishable without it. The doctrine has criticized this reading in fundamental terms, pointing out that it renders the named acts punishable irrespective of any threat to the protected interest, hence on the basis of pure risk, and a number of appellate courts continue to read the clause across all the acts enumerated.
Whatever the ultimate fate of that dispute, the case law offers the defense two footholds. First, ordinary hindrance does not suffice: what is required are obstacles of more than average gravity, not removable by the diligent analysis of documents which the authorities may fairly be expected to perform (judgment of the Court of Appeal in Katowice of 29 July 2016, II AKa 479/15). Secondly, a transaction that is overt, documented and routed through official banking channels is difficult to describe as apt to erase any trail. Candor requires the counterpoint: the statute says “may thwart”, so a potential danger suffices and no completed effect need be shown (judgment of the Court of Appeal in Lublin of 2 December 2015, II AKa 226/15).
The Circle of Potential Perpetrators
A. A General Offense; Laundering by the Predicate Offender
The offense under Article 299 § 1 CC is a general one: any natural person capable of criminal liability may commit it, whether acting personally or on behalf of a company. Since the 2000 amendment the perpetrator of the predicate may also be liable for laundering its proceeds, a point the Supreme Court settled by way of a legal principle in resolution I KZP 19/13. The fraudster who subsequently channels the defrauded moneys through a chain of accounts may accordingly answer for two distinct offenses.
B. The Boundary with the Predicate Offense
An important safety valve nevertheless remains. The acts of laundering cannot coincide with the acts by which the predicate itself was committed. The receipt of payment for narcotics, or the inflow of defrauded transfers onto the account of a front company, still belongs to the closing stage of the source offense; laundering begins only with the subsequent dispositions of the funds so obtained (judgments of the Court of Appeal in Białystok of 24 October 2016, II AKa 40/16, and of the Court of Appeal in Wrocław of 18 April 2018, II AKa 22/18). Indictments in economic cases have a tendency to blur this line, and policing it belongs to the elementary craft of the defense, since success removes Article 299 CC from the qualification altogether.
C. Employees of Obliged Institutions: Article 299 § 2 CC
A separate, individual offense concerns employees and persons acting in the name or on behalf of banks, financial or credit institutions and other obliged institutions within the meaning of the ustawa z dnia 1 marca 2018 r. o przeciwdziałaniu praniu pieniędzy oraz finansowaniu terroryzmu (Act of 1 March 2018 on Counteracting Money Laundering and Terrorism Financing; hereinafter: the AML Act), a field surveyed on our portal devoted to AML defense and financial compliance. Punishable is, among other things, the acceptance of assets contrary to the applicable provisions or in circumstances arousing a justified suspicion of their criminal provenance, as well as the rendering of other services intended to conceal that provenance or to shield the assets from seizure. The standard of justified suspicion means that the bank employee need not know that the client is laundering; it suffices that the symptoms ought to have alerted him and the transaction was executed nonetheless. For the management of obliged institutions the applicable standard of care is correspondingly higher, consistently with the general regime of board member liability. Independently of the liability of individuals, the entity itself may incur separate liability under the ustawa z dnia 28 października 2002 r. o odpowiedzialności podmiotów zbiorowych (Act of 28 October 2002 on the Liability of Collective Entities for Acts Prohibited under Penalty).
V. Sanctions
A. Basic and Aggravated Types
The basic types (§ 1 and § 2) carry imprisonment from 6 months to 8 years. The aggravated type of § 5, acting in concert with at least two other persons, a formula broader than joint perpetration and embracing other configurations of cooperation, and that of § 6, the obtaining of a substantial financial benefit, raise the range to between 1 and 10 years. In practice a benefit is treated as substantial above PLN 200,000, the definition of Article 115 § 5 CC being applied accordingly. Recent case law adds a limitation of real defensive value: the qualifying benefit must derive from the laundering itself, a commission for instance, and not from the value of the funds passed through nor from the loot of the predicate (judgment of the Court of Appeal in Warsaw of 10 January 2024, VIII AKa 34/23).
B. The Felony Threshold: Article 306b CC
Since 1 October 2023 Article 306b CC covers, among others, all the laundering types of Article 299 § 1, 2, 5 and 6 CC. Where the act concerns assets exceeding PLN 5 million, the penalty is imprisonment from 3 to 20 years; above PLN 10 million, from 5 to 25 years. A lower limit of at least 3 years makes the act formally a felony, a zbrodnia within Article 7 § 2 CC, with all the attendant consequences: no conditional discontinuation of the proceedings and a drastically narrowed range of probationary measures. In carousel litigation, where the sums recited in the charges run into tens of millions of złoty, this is today the principal driver of procedural risk. It should be recorded that in the course of work on a further reform of the Criminal Code the repeal of these provisions has been postulated as excessively punitive; unless and until such a change is enacted they remain the law in force (as of 22 August 2026).
C. Fine, Forfeiture and the Freezing of Assets
Alongside imprisonment the court may impose a fine of up to 3000 daily rates (Article 309 CC), which at the maximum daily rate of PLN 2000 yields, in theory, as much as PLN 6 million. Forfeiture under Article 299 § 7 CC is mandatory and reaches the objects deriving from the offense directly or indirectly as well as the benefits or their equivalent, even where they are not the property of the perpetrator; restitution to the injured party takes priority. Here too a genuine line of defense appears: the provision concerns the benefits of the laundering, not of the predicate (judgment of the Court of Appeal in Katowice of 1 September 2016, II AKa 267/16). In parallel operate the extended confiscation presumptions of Article 45 § 2 CC and the institution of security on assets, capable of paralyzing an enterprise long before any final judgment; the mechanics of seizure of company assets without a court judgment are treated separately on our pages.
D. Punishable Preparation: Article 299 § 6a CC
Preparation itself is punishable by imprisonment of up to 3 years. The formation of a corporate vehicle destined for a future transfer of incriminated assets, or an agreement to pass such funds through an account, thus constitutes a distinct prohibited act, although the doctrine views this construction critically as a criminalization of a remote preparatory field, difficult to reconcile with the ultima ratio principle of criminal law.
Account Blocking under the AML Act
Of the commencement of a laundering case the entrepreneur usually learns not from any procedural document but from a refused transfer. The sequence of Article 86 of the AML Act runs as follows: the obliged institution, having formed a justified suspicion, notifies the General Inspector of Financial Information (Generalny Inspektor Informacji Finansowej, GIIF) and itself withholds the transaction for 24 hours; the GIIF may demand the withholding of the transaction or the blocking of the account for up to 96 hours, Saturdays and statutory holidays being excluded from the computation; the prosecutor may then, by order, block the account for a definite period of up to 6 months, extendable once by a further 6 months. The block lapses if within that time no order securing assets or ruling on material evidence is issued, and an interlocutory appeal lies against the prosecutor’s order. Alongside this procedure operates the separate mechanism of STIR blocks imposed by the National Revenue Administration (KAS), together with the broader question of when the tax authority may inspect a bank account. The tactics of the frozen account, from the motion to release the block to the dispute over its quantitative scope, are examined in our study of what happens when the state freezes your money.
Impunity and Mitigation
The legislature left the perpetrator a gate, albeit a narrow one. Under Article 299 § 8 CC, no punishment is imposed upon one who voluntarily disclosed to the law enforcement authority information concerning the persons participating in the offense and the circumstances of its commission, provided that this prevented the commission of another offense; the procedural consequence is the discontinuation of the proceedings (Article 17 § 1 point 4 of the Code of Criminal Procedure). Where the perpetrator made endeavors toward disclosure which nevertheless failed to prevent another offense, the court applies extraordinary mitigation of the penalty, and does so mandatorily. The clause covers only the basic types of § 1 and § 2; perpetrators of the aggravated types are left with the general institution of Article 60 § 3 CC. A less familiar valve is Article 307 § 1 CC: toward the perpetrator of an offense under Articles 296, 299 to 305 or 306b CC who has voluntarily repaired the damage in full, the court may apply extraordinary mitigation or even waive punishment. Whether that provision genuinely fits laundering, where classical damage is elusive, remains disputed; its literal wording arguably supports application, and in negotiated resolutions the argument appears worth raising.
Laundering and the Handling of Stolen Goods
In practice a charge under Article 299 CC is sometimes brought in situations corresponding rather to the handling of stolen goods, paserstwo, under Articles 291 and 292 CC. The Court of Appeal in Warsaw drew the distinction persuasively: the handler deals with a thing deriving directly from the offense, acquiring it, accepting it or assisting in its concealment with a view to further use, whereas laundering begins where the conduct aims at legalization, and once the thing has been converted into an indirect benefit every subsequent act already falls under the more severely sanctioned Article 299 § 1 CC (judgment of 28 December 2022, II AKa 108/21). A cumulative qualification under Article 11 § 2 CC is possible, yet in many factual settings the two are alternatives, and the requalification of a laundering count into handling constitutes a realistic objective of negotiation, both the penal range and the forfeiture regime being milder.
Axes of Defense in Money Laundering Cases
From the construction described above there emerge six axes along which prosecutions under Article 299 CC are in practice resolved. The first is the predicate: insisting upon the specification of a concrete statutory type and resisting presumptions built solely upon the suspect character of the funds. The second is mens rea: demonstrating that the transaction had a commercial rationale, a market price and a documented verification of the counterparty, so that not even dolus eventualis can fairly be attributed. The third is the boundary with the predicate: excising from the charge those acts which still belonged to the source offense. The fourth is the modal clause: overtness, documentation and the official banking circuit as arguments against any capacity to erase the trail. The fifth concerns values and thresholds: contesting the crossing of PLN 200,000 under § 6 and of PLN 5 million or PLN 10 million under Article 306b CC, distinguishing the benefit of laundering from the loot of the predicate, and invoking the quantitative ceiling for commingled accounts. The sixth is the patrimonial front: interlocutory appeals against blocks and freezing orders and the argument of proportionality, since for a functioning enterprise the freezing of its accounts is frequently more destructive than the distant prospect of a penalty. To these must be added the tactics of the earliest stage: the boundary between witness and suspect is fluid, testimony given hastily in the former capacity tends to determine the course of the proceedings, and the witness’s privilege to decline an answer that might expose him or a person close to him to criminal liability (Article 183 § 1 of the Code of Criminal Procedure) demands preparation rather than improvisation.
Compliance Considerations
Prevention remains many times cheaper than defense. For the entrepreneur this means documenting the sources of larger sums, verifying counterparties before significant transactions, avoiding atypical structures devoid of commercial rationale, and preserving contracts, invoices and transfer confirmations; heightened caution is warranted for large cash transactions and for dealings with entities from jurisdictions of elevated risk or with shell companies. Invoice traffic constitutes a distinct field of exposure: even the purchase of fictitious invoices is apt to trigger a cascade of qualifications in which Article 299 CC appears as a matter of routine. Participants in the cryptoasset market should maintain a complete audit trail of their transactions, the more so as cryptocurrency transaction reporting grows ever tighter. For obliged institutions the standard is higher still: effective AML and know your customer procedures, transaction monitoring, training and diligent reporting to the GIIF are at once a regulatory duty and the best individual shield of employees against liability under Article 299 § 2 CC.
The Empirical Picture
According to the data of the GIIF for 2022, as discussed in the System of Criminal Law (SPK, vol. 9, 3rd ed., 2024, chapter by J. Długosz-Jóźwiak), the Inspector received 4505 suspicious activity reports, opened 2166 analytical proceedings and forwarded to the prosecution 326 principal notifications of a suspected offense under Article 299 CC, concerning assets exceeding PLN 2.87 billion; it further demanded the blocking of 715 accounts for a total of approximately PLN 160.5 million. In the same year 316 court proceedings were opened against 823 persons, 236 persons were finally convicted, and forfeiture of assets was adjudged in the amount of approximately PLN 213 million. The asymmetry carries a practical lesson: the charge is brought broadly, the final conviction arrives far more rarely, and the space for a rational defense is real. Estimates in the literature put the value of the laundering trade in Poland at some USD 10 billion annually, although figures of this kind are, by their nature, burdened with considerable uncertainty.
Concluding Remarks
Article 299 CC sits at the intersection of two pressures: the European and international drive toward ever fuller harmonization, and the domestic principle that criminal law should remain the ultima ratio. The legislature has, for three decades, yielded to the former; the courts, to their credit, have supplied the limiting principles the statute itself omits, from the requirement of a specified predicate, through the quantitative ceiling for commingled funds and the insistence on intent, to the boundary separating the predicate from the laundering that follows it. For the practitioner the conclusion is sober rather than comforting: the exposure is severe, since 1 October 2023 severe to the point of a felony, yet the elements of the offense are demanding, and each of them is a door at which a prepared defense may knock. Kancelaria Prawna Skarbiec represents clients in Polish proceedings concerning Article 299 CC, from the first summons and the blocked account to the trial itself, and advises obliged institutions on their compliance architecture; in matters of this kind the value of an early and unhurried diagnosis is difficult to overstate.
