Retroactive Law Application: Litigation's Impact Explored

The question of whether laws can be applied retroactively after litigation has been initiated is a complex one, and the answer depends on the specific circumstances and the jurisdiction in question. In general, laws are presumed to have only prospective effect and should not be applied retroactively to pending disputes and cases. This principle is often expressed as lex prospicit, non respicit, meaning that the law looks forward and not backward. However, there are exceptions to this rule, and courts may allow retroactive application of laws in certain circumstances. For example, a law may be applied retroactively if it is remedial or penal in nature, provided it favours the accused or convict. Additionally, laws may be applied retroactively if they are curative, emergency measures, or if they declare a substantive right for the first time. In the United States, the Fifth Amendment's due process clause disfavours retroactive application of statutes, as it is not considered fair to hold individuals liable for violating a law that did not exist at the time of the alleged violation. Nevertheless, there have been cases where the U.S. Supreme Court has allowed retroactive application of laws, such as in tax law cases.

Retroactive laws can change the legal consequences or status of past actions

Retroactive laws can indeed change the legal consequences or status of past actions. In the US, the legality of applying a law retroactively depends on whether the law improves or worsens the situation of the individuals it affects. If the latter, the law is deemed an "ex post facto" law and is prohibited by the US Constitution.

Ex post facto laws can criminalise actions that were legal when committed, aggravate a crime by placing it in a more severe category, change the punishment for a crime, extend the statute of limitations, or alter the rules of evidence to make conviction more likely. In criminal law, retroactive laws can increase, decrease, or eliminate legal sanctions, such as the length of sentences or sentence enhancements. However, both federal and Illinois law prohibit retroactive laws that increase penalties or impose new consequences on past actions.

The principle of disfavouring retroactive application of the law is rooted in the Fifth Amendment of the US Constitution, specifically the due process clause. It is generally considered unfair for an individual to be liable for violating a law that did not exist at the time of the alleged violation. However, courts may allow retroactive application of statutes, regulations, or standards in certain circumstances. For example, in SEC v. Chenery II, the US Supreme Court allowed the retroactive application of an SEC adjudicatory proceeding that applied a new standard of conduct.

In the American legal system, the legality of a retroactively applied law depends on whether it improves or worsens the situation of the individuals it affects. If it worsens their situation, it is deemed an "ex post facto" law and is prohibited by the US Constitution. This distinction was established in the 1798 case of Calder v. Bull, where the US Supreme Court ruled that "every 'ex post facto law must necessarily be retrospective, but every retrospective law is not an ex post facto law [and] the former only is prohibited.'"

Retroactive laws can increase, decrease, or eliminate legal sanctions

Retroactive laws can theoretically increase, decrease, or eliminate legal sanctions. However, in the United States, the Fifth Amendment's Due Process Clause prohibits the government from holding individuals accountable for actions that were not illegal at the time they were committed. This means that while retroactive laws can decrease or eliminate legal sanctions, they cannot increase them.

In the US, the legality of a retroactively applied law depends on whether it improves or worsens the situation of those it affects. If the law worsens the situation, it is known as an "ex post facto" law and is prohibited by the US Constitution. Ex post facto laws can have several effects: they can criminalise actions that were previously legal; they can aggravate a crime by placing it in a more severe category; they can change punishments by adding new penalties or extending sentences; they can extend the statute of limitations; or they can alter the rules of evidence to make conviction more likely.

On the other hand, a form of ex post facto law called an amnesty law can decriminalise certain acts. Alternatively, it can prohibit prosecution or remove punishment while leaving the underlying conviction technically unaltered. Pardons have a similar effect, but they are usually specific to individual cases rather than a class of cases. Other legal changes can also alleviate punishments retroactively, such as by replacing the death sentence with lifelong imprisonment.

Retroactive laws can be applied to civil law in the US, but there are some constitutional limits. Courts interpreting ambiguous statutes apply a general presumption against retroactivity. However, the Supreme Court has upheld statutes that decrease the frequency of parole eligibility hearings and statutes that decrease the severity of punishments.

Retroactive laws are generally disfavoured, and an individual will likely not be found liable for violating a statute that was not in effect at the time of their conduct. However, courts may allow retroactive application of statutes, regulations, or standards in certain circumstances. For example, in SEC v. Chenery II, the US Supreme Court allowed the retroactive application of an SEC adjudicatory proceeding which applied a new standard of conduct.

Retroactive laws are generally disfavoured as they are considered unjust and oppressive

The principle of opposing retroactive laws is rooted in the idea of fairness and due process. It is considered unjust to hold individuals accountable for actions that were not illegal at the time they were committed. Retroactive laws violate the basic principles of legality and introduce legal uncertainty, making it difficult for individuals to understand and follow the law.

Additionally, retroactive laws can lead to politically motivated justice and abuse of power. They can be used to target specific groups or individuals, particularly those who have accumulated wealth or power through past actions that are later criminalised. This undermines the social contract and the collective decision-making process that underpins the rule of law.

Furthermore, retroactive laws can have far-reaching consequences, affecting not only individuals but also communities and society as a whole. They can disrupt established social and economic relationships, leading to instability and uncertainty. Retroactive laws can also create a sense of injustice, particularly when applied to individuals who have already been sentenced or acquitted under existing laws.

While retroactive laws are generally disfavoured, there may be exceptional circumstances where they are deemed necessary to correct past injustices or address pressing societal issues. However, even in such cases, the potential benefits must be carefully weighed against the risks of undermining legal certainty and the rule of law.

Retroactive laws are allowed in certain circumstances, such as when a law is remedial in nature

In the United States, the retroactive application of laws is generally disfavored. The principle of disfavoring retroactivity is rooted in the Fifth Amendment of the U.S. Constitution, specifically the due process clause, which states 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, retroactive laws are allowed in certain circumstances. Courts may allow the retroactive application of statutes, regulations, or standards if the benefits outweigh the negative consequences. For example, in SEC v. Chenery II, the U.S. Supreme Court allowed the retroactive application of a new standard of conduct, stating that:

> "Every case of first impression has a retroactive effect, whether the new principle is announced by a court or by an administrative agency. But such retroactivity must be balanced against the mischief of producing a result which is contrary to a statutory design or to legal and equitable principles. If that mischief is greater than the ill effect of the retroactive application of a new standard, it is not the type of retroactivity which is condemned by law."

Additionally, federal courts have been more receptive to the retroactive application of tax laws. In U.S. v. Carlton, the U.S. Supreme Court held that an amendment to a federal estate tax statute and its retroactive application did not violate the Fifth Amendment because the taxpayer did not rely on the previous statute, Congress corrected an error, and the application only extended retroactively by one year.

Retroactive laws are also allowed if they remove or reduce the burden placed on people who have already been sentenced. This distinction was established in the 1798 Calder v. Bull case, where the U.S. Supreme Court ruled that:

> "There is a great and apparent difference between making an unlawful act lawful and the making an innocent action criminal and punishing it as a crime."

Retroactive reforms are designed to provide relief to individuals who have been disadvantaged by harsh, disproven, or overly broad policies of the past. They can be critical to sentencing reform and reducing prison populations by correcting extreme sentencing policies. For example, in 2015, Nevada passed a retroactive law that abolished life without the possibility of parole for most juvenile offenders, offering them parole review after 15 or 20 years served.

Retroactive laws are prohibited by the US Constitution and some other countries' constitutions

In the US, the legality of a retroactively applied law depends on whether the law would improve or worsen the situation of the individuals it would affect. If it worsens the situation, the law is known as an "ex post facto" law and is prohibited by the US Constitution. This is rooted in the Fifth Amendment of the US Constitution, i.e. the due process clause. In other words, it is not considered fair for an individual to be liable for violating a law that did not exist at the time of the alleged violation.

The US Constitution is not alone in prohibiting ex post facto laws. The constitutions of Albania, Brazil, Canada, Estonia, France, Germany, India, Indonesia, Iran, Ireland, Italy, Japan, Lithuania, Mexico, Norway, Pakistan, the Philippines, Poland, Portugal, Romania, Russia, South Africa, Spain, Sweden, Turkey, and the UK all include provisions prohibiting retroactive laws.

In addition, retroactive criminal sanctions are prohibited by Article 7 of the European Convention on Human Rights, Article 15(1) of the International Covenant on Civil and Political Rights, and Article 9 of the American Convention on Human Rights. While American jurisdictions generally prohibit ex post facto laws, European countries apply the principle of lex mitior ("the milder law"), which states that if the law has changed after an offense was committed, the version of the law that applies is the one that is more advantageous for the accused.
