Italy is this article's central case study, and the sharpest example of a jurisdiction stuck mid-project. Its Codice Penale, known as the Rocco Code after the Fascist-era Justice Minister who drafted it, was promulgated by royal decree in 1930 and remains formally in force nearly a century later, having survived four failed comprehensive reform commissions between 1992 and 2007 and only partial modernization through the 2022 Cartabia reform and the 2024 Nordio reform. France, Spain, and Indonesia, the three jurisdictions this article compares Italy against, each show that comprehensive replacement of an outdated or illegitimate-origin code is achievable, typically alongside a specific political-legitimacy trigger.
Even the cleanest comprehensive code, though, coexists with a dense parallel layer of special criminal legislation that keeps growing regardless of codification, the project's genuinely unfinished business. International criminal law took a fourth path entirely: it codified core crimes through the negotiated Rome Statute rather than a sovereign's legislative act or an expert body's draft code, proof that political negotiation among states can produce binding codified criminal law without any single enacting sovereign.
Four Founding Codes: Napoleon, Germany, Italy, and the American Template
Four founding codes anchor this comparison: France's Code pénal, Germany's Strafgesetzbuch, Italy's Codice Penale, and the United States' Model Penal Code, each representing a different codification method that later jurisdictions would follow or reject. Jeremy Bentham (1748-1832) supplied the theoretical case for writing law down at all well before any of the three approaches existed, arguing that law should be stated in clear language and grounded in a rational, ascertainable principle rather than accreted custom, an influence frequently credited across nineteenth-century codification efforts, including colonial projects such as Lord Macaulay's 1837 Indian Penal Code.
France moved first. The Code pénal of 1810 was decreed through seven laws issued between 12 and 20 February 1810 and promulgated by early March of that year. It replaced the shorter-lived Penal Code of 1791, consolidated the scattered criminal legislation of the revolutionary decade into a single 484-article text aligned with the companion 1808 Code of Criminal Instruction, and reinstated some harsher measures, including life imprisonment and branding, that the 1791 code had abolished. The 1810 code became the template exported to jurisdictions occupied by or allied with the First French Empire, seeding the civil law codification tradition across continental Europe. It remained in force for 184 years, until replaced on 1 March 1994.
Germany took a different route. The Strafgesetzbuch für das Deutsche Reich (StGB) was passed on 15 May 1871 and took effect on 1 January 1872, substantively a re-adoption of the 1870 North German Confederation code, timed deliberately to coincide with German political unification. Codification here served nation-building as much as legal tidying: a single criminal code was one component of consolidating disparate German states into a unified empire. Germany never wholesale-replaced this code. Instead it has amended the same text continuously for over 150 years, including the "Große Strafrechtsreform" restructuring of the General Part (Allgemeiner Teil), enacted in 1969 and effective 1 January 1975.
Italy replaced its own founding code once, but has not managed to do so a second time. The Zanardelli Code of 1889, named for Justice Minister Giuseppe Zanardelli, was liberal and Classical-School in orientation: it abolished the death penalty for ordinary crimes and introduced parole. It was replaced by the Codice Penale, promulgated by royal decree on 19 October 1930 under Mussolini's government, drafted under Justice Minister Alfredo Rocco (in office 1925-1932) and known ever since as the Rocco Code. Scholars frequently cite the Rocco Code's Title IV, "Delitti contro l'integrità e la sanità della stirpe" (crimes against the integrity and health of the race), as anticipating the 1938 Italian racial laws, a detail that explains why this code's continuity into a democratic republic is contested, a tension the next two sections develop in full.
The United States never had a single national code to replace, because American criminal law is constitutionally fragmented between federal law and fifty separate state codes. The Model Penal Code answered a different problem. Drafted by the American Law Institute over a decade, with Herbert Wechsler as chief reporter, and formally completed in 1962, it is not binding law anywhere in the United States. Instead it served as the basis for state-level recodification in more than two-thirds of states over the two decades that followed, with early adopters including Illinois in 1962, Minnesota and New Mexico in 1963, New York in 1967, and Georgia in 1969. It represents a fourth codification path distinct from the other three: an authoritative model, adopted voluntarily rather than enacted.
| Jurisdiction | Founding code | Enacted | Current status |
|---|---|---|---|
| France | Code pénal | 1810 | Replaced in 1994 |
| Germany | Strafgesetzbuch (StGB) | 1871 | Same code, continuously amended |
| Italy | Codice Penale (Rocco Code) | 1930 | Same code, four replacement attempts failed |
| United States | Model Penal Code (template only) | 1962 | Non-binding, adopted piecemeal by states |
Two Traditions, One Spectrum: Why Common Law Countries Resist Comprehensive Codes
Do common law countries ever produce comprehensive criminal codes? England and Wales is the leading counter-case, and the answer it supplies is no, not yet, despite trying. The Law Commission of England and Wales was created in 1965 with an explicit statutory mandate to pursue codification, and it launched a criminal-code project in 1967 that UK government sources describe as still "notionally continuing" as of 2026, with no comprehensive code ever enacted.
The nineteenth-century record was no better. England and Wales saw at least eight failed codification attempts by 1882, including Sir James Fitzjames Stephen's 1878 consolidation Bill, which was withdrawn, and a draft code produced by the Royal Commission on the Law Relating to Indictable Offences (1871-1879, chaired by Colin Blackburn, Baron Blackburn). The Law Commission's own 1989 report on a Criminal Code for England and Wales did not lead to enactment either.
The Commission states its current position directly, and it is worth quoting because it reframes decades of failure as deferral rather than rejection: a comprehensive code remains "desirable in principle, but not currently feasible as a single undertaking." Its actual practice is incremental, offense-area-by-offense-area statutory reform aimed at producing "code-ready" statutes without ever assembling them into one document.
That practice, however, is not proof that common law jurisdictions reject codification as a category. Most US states, despite common law origins, have Model Penal Code-influenced statutes that are functionally comprehensive codes in structure if not in name. "Common law jurisdictions don't codify" is true of England and Wales specifically. It is not true of common law jurisdictions generally, and the difference between those two claims is the real lesson of this comparison.
Italy's Unfinished Project: Four Failed Commissions and Two Partial Patches
Italy has the strongest legitimacy argument for comprehensive replacement of any jurisdiction compared in this article: a code drafted under a Fascist government in 1930 still governs a democratic republic nearly a century later. It also has the weakest record of doing anything about it. Legal scholars typically describe an unreplaced, dictatorship-drafted code left standing under a later democratic constitution as a form of authoritarian continuity, a charge that carries no equivalent for France's, Spain's, or Indonesia's already-completed replacements, discussed in the next section.
Four government-appointed commissions have produced complete draft codes since 1992, and none has reached the floor of Parliament as a comprehensive replacement. The Pagliaro Commission, chaired by Prof. Antonio Pagliaro, completed its draft in 1992, covering both the general and special parts of a prospective new code. The Grosso Commission, chaired by Prof. Carlo Federico Grosso, was appointed by Justice Minister Giovanni Maria Flick in 2001. The Nordio Commission, sitting from 2004 to 2005 and chaired by then-magistrate Carlo Nordio, was appointed by Justice Minister Roberto Castelli and presented a comprehensive project that was shelved. The Pisapia Commission, sitting from 2006 to 2007 and chaired by Giuliano Pisapia, was also shelved.
Instead of comprehensive replacement, Italy has pursued targeted, procedure-focused reform twice in the past four years. The Cartabia reform, Legislative Decree No. 150 of 10 October 2022 implementing the enabling Law No. 134/2021, took effect on 1 November 2022. It restructured criminal-procedure timelines, introduced a comprehensive restorative-justice framework, and adjusted the sanctions system, all without touching the Rocco Code's substantive core.
The Nordio reform, Law No. 114 of 9 August 2024, carries the name of the same Carlo Nordio who chaired the shelved 2004-2005 commission and now serves as Justice Minister. It abolished the crime of abuso d'ufficio (abuse of office, formerly Article 323 of the Codice Penale) and narrowed traffico di influenze illecite (illicit influence trafficking, Article 346). The stated motivation was concern that vague liability under the old abuso d'ufficio standard was producing a "fear of signing" (timore della firma) among public officials reluctant to make ordinary administrative decisions. This is a targeted, codification-adjacent technique, decriminalizing a specific offense rather than replacing the code. It is related to, but distinct from, the broader European trend of removing conduct from the criminal law entirely that the next article treats in full.
That abolition, however, is not the end of the story. Reporting current to around April 2026 indicates the European Parliament approved a directive in December 2025 that may require Italy to reintroduce some form of abuse-of-office offense, with Minister Nordio reported as resistant as of that reporting. This has not been independently confirmed against a primary EU or Italian government source, and it should be read as a live, unresolved conflict between EU-level harmonization pressure and domestic reform, not as a settled outcome in either direction.
When Replacement Actually Happens: France, Spain, and Indonesia
France, Spain, and Indonesia demonstrate that comprehensive replacement of an outdated or illegitimate-origin code is achievable, though the three cases arrived at that outcome by different routes.
France's 1994 Code pénal took the longest road of the three. A drafting commission was created in 1974 under President Valéry Giscard d'Estaing, revived under Justice Minister Robert Badinter after 1981, prioritized by President François Mitterrand from 1989, passed by Parliament in 1992, and brought into force in 1994. That is roughly a two-decade gap between initial commission and enactment, replacing a code that had itself stood for 184 years. France's case is less a rupture with a prior regime than a demonstration of how difficult it is to build parliamentary consensus on hundreds of articles simultaneously, even inside an established, stable democracy.
Spain's 1995 Código Penal moved differently. Organic Law 10/1995 was enacted on 8 November 1995 and published on 23 November 1995, the product of more than fifteen years of debate following Spain's 1978 democratic Constitution. Spanish legal culture calls it the "Código Penal de la democracia," a name that states its purpose directly: aligning criminal law with democratic constitutional values after the Franco era. This is a clean example of codification functioning as a symbolic rupture with a prior political order, not merely a technical update.
Indonesia's KUHP (Kitab Undang-Undang Hukum Pidana) supplies a third variation on the same theme. Passed by the legislature in 2022 and brought into force on 2 January 2026, it replaced the Wetboek van Strafrecht voor Nederlandsch-Indië, a Dutch colonial code dating to 1918, more than eighty years after Indonesian independence in 1945. A companion new Code of Criminal Procedure (KUHAP) replaced 1981-era procedural law at the same time. Indonesian officials framed enforcement explicitly as ending "the colonial criminal law era," and the new code's most-cited substantive shift is from a retributive toward a more restorative model.
The synthesis these three cases support is direct. Spain's post-Franco constitution and Indonesia's post-colonial break both supplied a specific political-legitimacy trigger for comprehensive replacement. France's less dramatic, generational effort shows that the same outcome is reachable through sustained executive priority alone, without any comparable rupture. Italy, by contrast, has had the strongest legitimacy trigger of all four cases, a dictatorship-era code still governing a democratic republic, and the weakest result. That combination suggests legitimacy pressure alone does not predict successful codification. Sustained political priority, of the kind France's executive maintained across three presidencies and Spain's cross-party consensus maintained across fifteen years, appears to be the decisive variable Italy has lacked across four attempts.
The Code's Unfinished Business: Special Legislation and Legislative Sprawl
Even a jurisdiction with a clean, comprehensive core code develops a parallel body of special criminal legislation, leggi penali speciali in Italian legal terminology, sitting outside that code and covering tax, environmental, financial-market, and immigration offenses. A code can organize the general part and core offenses, such as homicide, theft, and assault, cleanly enough. The modern regulatory state generates criminal liability faster than any single code absorbs it, and closing that gap is the one piece of the codification project no jurisdiction in this comparison has finished.
D.Lgs. 231/2001, Italy's corporate criminal liability decree, is the concrete Italian example: legislation sitting entirely outside the Codice Penale that allows direct criminal liability of a legal entity itself, rather than only the individuals who act for it. This article names the regime only as an instance of the pattern. How D.Lgs. 231/2001 actually holds a company criminally liable, including its compliance-model defense, predicate-crime catalogue, and sanction structure, is the full subject of the next article.
D.P.R. 448/1988 supplies a second Italian example. It is Italy's separate juvenile criminal-procedure code, an entirely different text from the adult Codice di Procedura Penale, and another instance of law sitting outside the "clean" core rather than being absorbed into it. the article on the age of criminal responsibility and juvenile justice reform covers that regime, including its messa alla prova and irrilevanza del fatto mechanisms, in full.
EU directive transposition supplies a modern, EU-specific version of the same pattern. National statutes transposing EU cybersecurity and cybercrime directives, such as Italy's NIS2-transposing D.Lgs. 138/2024, sit alongside the Codice Penale as special legislation exactly like the older examples above, reflecting the same minimum-harmonization logic, a floor rather than a ceiling, that the article on how EU directives like NIS2 get transposed into national special legislation documents in detail.
The United States federal system is the extreme, quantified case, and the figures need a hedge attached every time they appear. An estimated 5,000 federal statutory crimes exist today, up from roughly 3,000 in the early 1980s, about 4,000 by 2000, and over 4,450 by 2008; an estimated 60 new federal crimes are enacted per year; and an estimated 300,000 to 400,000 federal regulatory offenses sit embedded in a Code of Federal Regulations spanning over 48,000 sections and roughly 175,000 pages. All of these are Heritage Foundation estimates, not an official government count, and the 2026 "Count the Crimes to Cut Act," introduced by Senators Mike Lee and Chris Coons, is itself evidence that no government body currently produces one: the bill's entire purpose is creating that count for the first time. No comparably quantified estimate exists for Italy's or Germany's special-legislation volume, a genuine data gap rather than a number to approximate here.
Codifying Beyond the State: The Rome Statute and the Road Not Fully Taken
International criminal law followed a different path from any of the domestic examples above. Its own expert body never produced the operative code, despite decades of trying.
The International Law Commission's Draft Code of Crimes Against the Peace and Security of Mankind was first assigned by a UN General Assembly resolution in 1947, produced an initial draft in 1951, and reached a stable 20-article form in 1996, covering aggression, genocide, crimes against humanity, war crimes, and crimes against UN and associated personnel. The Commission itself, in 1996, left open whether that draft should become a standalone convention, be folded into a criminal court's statute, or remain a non-binding declaration.
In practice, a negotiated treaty settled the question instead. The Rome Statute of the International Criminal Court was adopted on 17 July 1998 at a diplomatic conference, not solely an ILC exercise, though the Commission's parallel Draft Statute for an International Criminal Court fed into the preparatory process. The Rome Statute became the operative codification: it defines four core international crimes, genocide, crimes against humanity, war crimes, and the crime of aggression, and it entered into force on 1 July 2002. As of January 2025, 125 states are parties.
The Rome Statute is neither a sovereign legislative act, the civil law model surveyed above, nor judicial accretion, the common law model. It is a negotiated multilateral treaty that functions as a code despite lacking any single enacting sovereign. At the international level, political negotiation among states proved more effective at producing binding codified criminal law than expert-body drafting alone, effectively superseding the ILC's more classically "codification-style" draft-code approach. Whether that same lesson extends back to the domestic cases this article opened with, that sustained political negotiation succeeds where technical drafting alone does not, is the question the rest of the remaining articles take up from here.
Frequently Asked Questions About Criminal Law Codification
Has Italy's Rocco Code ever been replaced?
No. The 1930 Codice Penale is still Italy's current code, carried forward through decades of piecemeal amendment, constitutional-court rulings, and the 2022 and 2024 reforms discussed above, but never through a single comprehensive Act.
Is the Model Penal Code United States federal law?
No, and it never has been anywhere in the country. It functions purely as a persuasive template that individual state legislatures were free to draw on, which most of them did to varying degrees once recodifying their own statutes after 1962.
Does codification mean a criminal code stops changing once it is enacted?
Rarely, for a long-lived code. Germany's StGB has kept changing for over a century and a half without ever being wholesale-replaced, and France, despite retiring its own 184-year-old code in 1994, launched a full recodification à droit constant, a reorganization rather than a substantive rewrite, of its Code of Criminal Procedure in late 2025, with an entry-into-force target as late as 2030.
Did the International Law Commission's 1996 Draft Code become the Rome Statute?
No. The Rome Statute that entered into force in 2002 came out of a separately negotiated diplomatic conference, not from the Commission's own draft becoming binding law. The ILC's parallel work on a draft statute for a criminal court fed into that negotiation, but the 1996 Draft Code of Crimes itself was never adopted in the form the Commission produced it.
What Comes Next
This article opens the Legal Reform and Policy series, and its job has been to establish a baseline question the remaining four articles each apply to narrower ground: how a legal system decides to write its criminal law down, replace it wholesale, or leave it to grow by accretion. The next four pieces take up that question from different angles. One examines the broader European trend of removing conduct from the criminal law entirely, decriminalization rather than codification. Another traces how corporate entities get held criminally liable through legislation that sits outside the code, using Italy's D.Lgs. 231/2001 as its central case. A third examines how sentences get calibrated to the offense once a code exists. A fourth compares how different systems let time itself limit when a prosecution can still proceed. Each returns to the same underlying legislative-design problem this article has set out: what gets written into the code, and what gets left outside it.
