Are retroactive laws unconstitutional?
Ex post facto laws are expressly forbidden by the United States Constitution in Article 1, Section 9, Clause 3 (with respect to federal laws) and Article 1, Section 10 (with respect to state laws).
The Fifth Amendment's Due Process Clause prohibits the government from depriving any person of “life, liberty, or property, without due process of law.” Litigants have often challenged retroactive civil laws on due process grounds, alleging that such laws impermissibly create unforeseen liability for past actions.
Retroactive Judicial Decisions
At a minimum, ex post facto prohibits legislatures from passing laws which retroactively criminalize behavior. However, this prohibition does not attach as strictly to judicial decisions.
In California, as in most states, a statute is presumed to operate prospectively. When construing statutes, there's a general presumption against retroactive cases unless the Legislature plainly has directed otherwise.
Retrospective legislation at common law
While there is a presumption at common law that statutes are not intended to have retrospective effect, there is no prohibition on retrospective legislation where the intention to operate retrospectively is expressly or impliedly clear from the wording of the statute.
As a general rule, laws shall have only a prospective effect and must not be applied retroactively in such a way as to apply to pending disputes and cases.
New laws enacted by the legislature usually affect only future conduct. Sometimes, however, legislation affects cases that are pending in the court system or conduct that occurred before the law was passed, these cases are known as “retroactive laws.”
Judges tend to defer to precedent because it encourages uniformity, predictability and consistency in the legal system, and historically the Supreme Court only overturned decisions when the original solution proved “unworkable,” or when the conditions on the ground had changed dramatically.
The Constitution of the United States forbids Congress and the states to pass any ex post facto law. In 1798 it was determined that this prohibition applies only to criminal laws and is not a general restriction on retroactive legislation.
Definition. The Oxford Dictionary of Law defines retrospective or retroactive legislation as “legislation that operates on matters taking place before its enactment, e.g. by penalising conduct that was lawful when it occurred.
When can a law have retrospective effect?
If an enactment expressly provides that it should be deemed to have come into effect from a past date, it is retrospective in nature. It then operates to affect existing rights and obligations, and is construed to take away, impair or curtail, a vested right which had been acquired under some existing law.
For example, in SEC v. Chenery II, the U.S. Supreme Court allowed retroactive application of an SEC adjudicatory proceeding which applied a new standard of conduct, stating: “Every case of first impression has a retroactive effect, whether the new principle is announced by a court or by an administrative agency.
As a general proposition judicial decisions are said to enunciate the law as it has always existed. Hence decisions have retroactive effect in all but a few types of civil cases.
The retrospective laws aim to focus on acts committed in the past before the commencement of the statute. On the other hand, any ex-post facto law might impose various new obligations on the transactions or any act committed by an individual or impair the vested rights.
Retrospective law or an ex post facto law is one that retroactively changes the legal consequences of actions that were committed, or relationships that existed, before the enactment of the law. In criminal law, its effect may criminalize action that was legal when committed.
When the Supreme Court rules on a constitutional issue, that judgment is virtually final; its decisions can be altered only by the rarely used procedure of constitutional amendment or by a new ruling of the Court.
The Library of Congress tracks the historic list of overruled Supreme Court cases in its report, The Constitution Annotated. As of 2020, the court had overruled its own precedents in an estimated 232 cases since 1810, says the library.
Declaration Of Law By Court Will Have Retrospective Effect If Not Otherwise Stated Specifically : Supreme Court. The Supreme Court reiterated that the declaration of law made by court will have retrospective effect, if not otherwise stated to be so specifically.

Rule Or Law Cannot Be Construed As Retrospective Unless It Expresses A Clear Or Manifest Intention To The Contrary: Supreme Court.
13.1 At common law, a statute will be presumed not to have retrospective operation. In the case of criminal laws, this presumption is based on a firm disapproval of laws that impose a penalty for an action that was lawful when it was done.
Taxation laws, for example, are often passed with retrospective effect but are typically backdated to the date of an announcement by the Government that the law will be created in the future. As a result, potential perpetrators are put on notice in time to change their behaviour.
The Constitution of the United States forbids Congress and the states to pass any ex post facto law. In 1798 it was determined that this prohibition applies only to criminal laws and is not a general restriction on retroactive legislation.
An ex post facto law is a law that changes the legal status or consequences of an action after it has already been done, especially a law that makes an action illegal after it has been committed.
To ensure the separation of powers, the Constitution prohibits Congress from issuing Bills of Attainder. Only the court system is permitted to determine whether someone has violated a law and to issue punishment. Similarly, Ex Post Facto laws are prohibited as well.
