Retroactive Law Application: Ethical Or Unjust?

The concept of retroactivity in law refers to the application of new legislation or rulings to previous cases or actions that occurred before the law came into effect. While the legality of retroactive laws varies across different jurisdictions, the general principle is that retroactive laws are disfavored, particularly in criminal law. However, there are circumstances where retroactive application of laws or rulings can be beneficial, especially in correcting injustices or extreme sentencing policies of the past. The determination of whether a law or ruling can be applied retroactively often depends on the specific wording of the statute, the intent of the legislature, and the potential impact on the individuals affected.

Retroactivity in criminal law

The principle of non-retroactivity in criminal law, which prohibits the application of law to events that took place before the law was introduced, is a widely accepted and binding norm of international law. This principle, which first emerged in Roman law, is rooted in the idea of fairness and due process, stating that it is not considered fair for an individual to be held liable for violating a law that did not exist at the time of the alleged violation.

However, there are exceptions and nuances to this principle. For instance, in the case of SEC v. Chenery II, the U.S. Supreme Court allowed the retroactive application of a new standard of conduct, acknowledging that every case of first impression has a retroactive effect. Additionally, in the context of administrative or domestic law, retroactivity is not always prohibited. States can adopt administrative regulations with retroactive effect to pursue legitimate public policy objectives, particularly in areas like environmental law and tax law.

The application of non-retroactivity in criminal law varies across jurisdictions. For example, Article 25, paragraph 2, of the Italian Constitution explicitly prohibits indictment pursuant to a retroactive law, while Article 90 of the Constitution of Croatia allows for limited retroactivity in exceptional circumstances. In France, while "lois rétroactives" (retroactive laws) are technically prohibited, the Conseil Constitutionnel has determined that they can be passed within certain limits, particularly in financial or tax legislation.

The determination of whether a statute or amendment should be applied retroactively involves statutory interpretation. Amendments are generally presumed to have prospective application unless the legislature explicitly states or clearly indicates a preference for retroactivity. However, remedial legislation, which aims to correct imperfections in prior law, is typically given retroactive effect to effectuate its beneficial purpose. Courts consider factors such as legislative history, fairness, and urgency when deciding on the retroactive application of statutes.

Retroactivity in tax law

In the United States, retroactive tax legislation is not absolutely barred by the Constitution. The Supreme Court has deemed it a "customary congressional practice", and there are few examples of it being struck down as unconstitutional. However, it is possible for retroactive tax legislation to violate the Constitution, particularly the Due Process Clause of the Fifth Amendment, which states that no person shall "be deprived of life, liberty, or property, without due process of law".

The standard used to determine whether retroactive tax legislation violates substantive due process is the rational basis test, which asks whether the retroactive application is "supported by a legitimate legislative purpose furthered by rational means". This is a low standard of review by the courts, and once met, judgments about the wisdom of such legislation are left to the legislative and executive branches.

Despite the general presumption against retroactivity, there are certain situations in which retroactive tax laws may be deemed necessary or permissible. For example, in the case of SEC v. Chenery II, the U.S. Supreme Court allowed the retroactive application of an SEC adjudicatory proceeding, acknowledging that "every case of first impression has a retroactive effect". The Court emphasised that such retroactivity must be balanced against the potential negative consequences of applying a new standard retrospectively.

In other countries, retroactive laws, including tax laws, may be permitted within certain limits. For instance, in France, while "lois rétroactives" (retroactive laws) are technically prohibited by the Code Civil, the Conseil Constitutionnel has determined that they can be passed in certain circumstances, particularly where it is considered to be in the "general interest". On the other hand, some countries have explicit prohibitions on the retroactive application of laws, such as Italy, Japan, and Lithuania.

Retroactivity in sentencing

In the United States, the legality of retroactively applied laws depends on whether the law improves or worsens the situation of those it affects. Laws that worsen the situation, known as "ex post facto" laws, are prohibited by the US Constitution. However, laws that retroactively reduce the burden on individuals who have already been sentenced are not prohibited. This distinction is a vital feature of the US justice system, recognising that courts can make mistakes and that fair and proportionate justice takes precedence over finality in sentencing.

The US Sentencing Commission, an independent agency within the judicial branch, plays a crucial role in retroactivity in sentencing. The Commission seeks public comment on proposed amendments to federal sentencing guidelines and considers the potential impact of retroactive guideline amendments. For instance, the Commission has proposed retroactive sentence reductions for drug trafficking and crack cocaine offences.

While retroactivity in sentencing can provide relief to those affected by harsh or disproven policies, it also presents challenges. Courts must carefully consider the Legislature's intent and ensure that retroactive application does not impair vested rights or bestow additional rights unfairly. The principle of disfavoring retroactive application of statutes is rooted in the Fifth Amendment of the US Constitution, emphasising that individuals should not be held liable for violating a law that did not exist at the time of their actions.

Retroactivity in procedural matters

The retroactive application of procedural laws is generally not considered a violation of rights or constitutionally objectionable. This is because procedural laws typically do not create or take away vested rights but instead focus on the remedy or confirmation of existing rights. Courts consider the intent behind remedial statutes and whether they aim to correct imperfections in prior laws or provide relief to aggrieved parties.

However, there are limitations to retroactivity in procedural matters. Courts must consider whether retroactive application would impair vested rights or bestow additional rights. If applying a new procedural law to pending proceedings would impair vested rights or create intricate due process issues, courts may deny its retroactive application.

The approach to retroactivity in procedural matters also varies internationally. For example, in France, Article 2 of the Code Civil technically prohibits retroactive laws, but in practice, the Conseil Constitutionnel has allowed retroactive tax laws within certain limits. In Italy, Article 25, paragraph 2, of the Italian Constitution prohibits indictment under retroactive laws, while in Japan, Article 6 of the Criminal Code mandates the application of the lighter punishment if a new law comes into force after the deed was committed.

Retroactivity in constitutional rulings

The retroactive application of laws is generally disfavoured, as it is not considered fair for an individual to be held liable for violating a law that did not exist at the time of the alleged violation. However, courts may allow retroactive application under certain circumstances. This is a complex area of law, and the approach varies across different jurisdictions.

In the United States, the Supreme Court (SCOTUS) may allow new constitutional rulings to be applied retroactively. This means that if a new ruling would have affected a sentence, a person may be able to petition a lower court to reconsider their sentence. This is the case even if the sentence was handed down before the new ruling was issued. However, SCOTUS rarely explicitly states that a ruling is retroactive, and it can be difficult to determine if a rule is considered "new".

SCOTUS has provided some guidance on this issue. In the 1990 case of Saffle vs. Parks, the Court held that if one of its decisions breaks new ground, overturns precedent, or imposes new responsibilities on a government party, then it is considered a "new" rule. Importantly, only a substantive ruling can be deemed a new constitutional law that applies retroactively; procedural rulings do not have retroactive effect. Substantive rulings are those that narrow the scope of a criminal statute or place certain conduct or persons beyond the state's power to punish. Procedural rulings relate to the manner in which a trial is conducted, such as the admissibility of evidence.

In the United States, federal courts have been more receptive to the retroactive application of tax laws. Additionally, remedial legislation or statutes governing procedural matters should be applied retroactively unless such application would impair vested rights or bestow additional rights.

In other countries, the approach to retroactivity in constitutional rulings also varies. For example, in France, retroactive laws ("lois rétroactives") are technically prohibited by Article 2 of the Code Civil. However, in practice, the Conseil Constitutionnel has determined that retroactive laws can be passed within certain limits, particularly in the case of financial or tax legislation. In contrast, in Italy, Article 25, paragraph 2 of the Italian Constitution prohibits indictment pursuant to a retroactive law. Similarly, Article 39 of the Constitution of Japan prohibits the retroactive application of laws, while in Croatia, Article 90 of the Constitution states that only individual provisions of a law may have a retroactive effect for exceptionally justified reasons.
