DOCTRINE OF RETROSPECTIVE LEGISLATION

Retrospective means applying new laws or changes to existing laws to events or actions that occurred in the past. This means that actions or events that were legal when they happened may become illegal or subject to new rules due to changes in laws afterward. For example, if someone did something that was not against the law at the time, but later the law is changed to make it illegal, that person could still be held accountable for their past actions under the new law. Retrospective laws can affect how past events are judged or regulated based on current legal standards or changes in legislation.

The meaning of the word retrospective is backdated or to look back. Therefore, the retrospective law is a law that has backdated effect or is effective since before the time it is passed. The retrospective law is also referred to as ex post facto law. Whether the Retrospective law is ultra vires to the Constitution or against the law of natural justice? The answer to this question depends upon the nature of the law passed. Whenever the retrospective law impairs the obligation of contract, it is void. However, law which only varies the remedies, divests no right, but is curative and merely cures a defect in the proceedings is fair and valid.

Article 20 of the Constitution of India prohibits the legislature to make retrospective criminal laws, however, it does not prohibit a civil liability retrospectively i.e. with effect from a past date. Therefore, tax can be levied retrospectively. However, in tax law, if there is a penal provision, retrospectively is not permitted to that extent.

Here are the differences between retrospective laws and ex-post facto laws:

1. Scope of Application:

  – Retrospective Laws: These laws are specially designed to consider all happenings or actions that occurred in the past and implement new rules or alterations from a date prior to that action or happening. Such laws affect all things that happened before they were made official.

  – Ex-post facto Laws: These, in fact, turn events from the past into acts of criminality, in addition to establishing a new category of punishment for actions considered legal at the time they were done. These laws make actions criminal after the fact rather than changing prior minutes.

2. Prohibition:

  – Ex-post facto Laws: These laws are explicitly prohibited in India and many other legal systems because they impose penalties or liabilities for actions that were not considered illegal at the time.

  – Retrospective Laws: While some retrospective laws may have similar effects to ex-post facto laws, not all retrospective laws are prohibited. For example, retrospective tax amnesties or changes in civil laws can be introduced legally.

3. Purpose and Effect:

  – Retrospective Laws: These laws generally aim to correct or update legal frameworks without necessarily imposing new penalties or criminalizing past conduct. They can be used for administrative purposes, tax reforms, or to rectify legal uncertainties.

  – Ex-post facto Laws: These laws specifically alter the legal consequences of past actions by making them illegal retroactively or increasing the severity of penalties. They can affect vested rights and impose new obligations on individuals or entities.

In essence, while both retrospective and ex-post facto laws involve looking back at past events, ex-post facto laws specifically change the legal consequences of past actions in a way that retrospective laws may not always do. Retrospective laws can serve various purposes beyond criminal law, including administrative and regulatory changes, whereas ex-post facto laws are strictly limited due to their potential impact on legal rights and fairness.

Ex post facto laws

Retrospective laws

All ex post facto laws are to be necessarily retrospective laws.

All retrospective laws are certainly not ex post facto laws. These are a bigger set of which ex post facto laws form a part.

Ex post facto laws are prohibited to be formulated in India.

Retrospective laws, if explicitly mentioned, are allowed to be introduced, however, with certain restrictions.

Ex post facto laws impose various new obligations on the transactions or acts committed by an individual or impair certain vested rights.

Retrospective laws focus on all the acts committed in the past before the commencement of the statute.

Retrospective laws for taxation 

Retrospective laws, especially in tax matters like the Amnesty scheme, are often used to offer rebates or relief to individuals who have failed to file taxes on time. This was particularly relevant during the Covid-19 pandemic, where millions lost their jobs and many faced bankruptcy. Even small business owners struggled greatly. Consequently, many found themselves unable to meet their tax obligations promptly.

Retrospective statutes in tax laws allow the government to change tax obligations after transactions have already occurred. By amending tax laws with retroactive effects, one can reduce taxes owed. They could also tack on taxes to past transactions in an effort to address gaps that businesses have had with previous policies. This intends to correct and make the historical situations fair in terms of business alignment with current tax policies. It aims to clear off some benefits that have been granted to businesses through loopholes in earlier tax policies.

RELEVANT JUDGEMENTS

In the case of Commissioner of Income Tax v. Hindustan Electro graphite Ltd (1998), the issue revolved around whether certain provisions of the Finance Act of 1990, which imposed tax on cash compensatory support retrospectively, were valid.

Facts:

Hindustan Electro graphite Ltd, a public limited company, had filed its income tax returns for a certain year but did not include an additional amount representing cash compensatory support in its taxable income. At the time (before the Finance Act of 1990), this cash compensatory support was not considered taxable income under the prevailing tax laws of 1989. However, the Finance Act of 1990 introduced provisions with retrospective effect, requiring such cash assistance to be taxed.

Issues:

1. Whether the retrospective amendment of tax on cash compensatory support done through the Finance Act of 1990 was valid?

2. Could these provisions be said to be penal in character?

Analysis

In Commissioner of Income Tax v. Hindustan Electro graphite Ltd (1998), the court upheld the retrospective application of tax amendments introduced by the Finance Act of 1990. It ruled that taxing cash compensatory support retrospectively was valid under tax laws aimed at revenue generation, distinguishing it from penal legislation. This case underscores the legal authority to adjust tax obligations retroactively, impacting taxpayers’ financial planning and compliance with evolving tax regulations.

Judgment:

The court held that the retrospective provisions of the Finance Act of 1990, requiring tax on cash compensatory support, were valid and not penal in nature. The key reasoning was that while penal laws cannot be applied retrospectively, tax laws serve a different purpose – to raise revenue for the government – and thus can have retrospective effect without being considered penal.

Conclusion 

In the case, Hindustan Electro graphite Ltd argued that the retrospective tax imposition was unfair and akin to a penalty. However, the court disagreed, ruling that tax laws can be applied retrospectively to ensure revenue collection, as they serve a financial purpose rather than being punitive. Therefore, the provisions of the Finance Act of 1990 were upheld as valid, allowing the tax authorities to enforce taxation on cash compensatory support retroactively.

In the case of Garikapatti Veeraya v. N Subiah Choudhary (1957), the Supreme Court dealt with an appeal where the required amount for appeal to the High Court was Rs 20,000, but the suit amount was Rs 11,000, resulting in the appeal being disallowed due to insufficient funds.

Key Points

1. Issue: The appeal to the High Court was rejected because the amount required for appeal was higher than the suit amount.

2. Court’s Ruling: The Supreme Court stated that unless there is a clear statement indicating retrospective application, laws cannot be presumed to have retrospective effect. Therefore, existing laws at the time of litigation determine the validity of claims.

Thus, the principle holds that the retrospective application of laws is prohibited without specific literals to that effect. Courts rely on the law as it was when the dispute originally arose rather than retrospectively applying a later enactment in determining whether claims made in the course of litigation are valid. This principle ensures clarity and fairness in legal proceedings, preventing unexpected changes in legal obligations after disputes arise.

ISSUES OF RETROSPECTIVE LEGISLATION

Retrospective laws, while aiming to hold people accountable for past actions or close loopholes, pose significant challenges and drawbacks:

1. Violation of Basic Rights: They can violate the principle of equality under the law, treating individuals unfairly based on when a law is enacted.

2. Lack of Foreknowledge: Individuals may be punished for actions that were legal at the time they were committed, as they could not have known about future legal changes.

3. Legal Complication and Delay: Because of these retroactive laws will normally require approval from the Supreme Court which could delay trials and create legal uncertainties. 

4. Limited Scope: It is usually applicable to criminal and taxation matters only, thereby narrowing the applicability. 

5. Tax Evasion and Ambiguity: They are useful in recovering taxes evaded through loopholes, but the period of applicability may create disputes.

6. Impact on Legal Stability: Short-term amendments can destabilize existing laws, essential for legal predictability and growth.

7. Application Restrictions: Only substantive civil laws can be applied retrospectively to limit the scope of retroactive legislation. 

These issues relate to a very procedural, democratic, and rights context problem with backward applicability of a law.

CONCLUSION 

While retrospective laws can be beneficial in some cases, they also raise significant concerns about violating people’s rights and complicating legal procedures under the Constitution of India. To strike a balance between government interests and citizen rights, these laws should be used sparingly. Recent Supreme Court decisions affirm the legislative authority to enact such laws, but they should be applied judiciously to ensure fairness and justice for all. Ultimately, any law, whether retrospective or prospective, must uphold democratic principles. If a law undermines these principles, especially in the case of retrospective legislation, corrective action should be taken.
