The legal document discusses the applicability and implications of Section 143A of the Negotiable Instruments Act, 1881, in relation to offences under Section 138. The key points are as follows:

1. Prospective Application of Section 143A: The section must be understood to have prospective operation, meaning it applies only to offences committed after its enactment. It is not retrospective, and its provisions cannot be invoked for offences prior to its introduction.

2. Creation of New Obligations and Disabilities: Section 143A imposes a new liability on the drawer of a dishonoured cheque, allowing the court to order interim compensation before the conclusion of trial or conviction. This introduces a new disability, as the accused can be compelled to pay interim compensation using coercive recovery machinery, as if the amount were arrears of land revenue.

3. Recovery Machinery and Coercive Methods: The section authorizes recovery of interim compensation through the same mechanisms used for land revenue arrears, which may include coercive methods such as attachment, sale of property, or arrest in some jurisdictions. This signifies a departure from the traditional post-conviction recovery process, which only applies after guilt is established.

4. Legal Principles on Retrospective Legislation: The document emphasizes that legislation affecting substantive rights is presumed not to have retrospective effect unless explicitly stated or clearly implied. Procedural laws, unless affecting substantive rights or creating new liabilities, are generally presumed to operate prospectively.

5. Comparison with Other Provisions: The document distinguishes Section 143A from provisions that apply after conviction, such as those related to the levy of fines or recovery of amounts as land revenue. Since Section 143A allows for liability prior to guilt being established, it is classified as affecting substantive rights and is thus prospective.

6. Implication for Pending Cases: In cases where offences were committed before the enactment of Section 143A, the section cannot be invoked. Orders for interim compensation made under this section in such cases are invalid, and any deposits made should be refunded.

7. Conclusion: The court concludes that Section 143A is prospective and can only be applied to offences committed after its introduction. Orders based on its retrospective application are to be set aside, and deposits made under such orders should be returned to the accused.

These points collectively reaffirm the principle that new legal provisions creating substantive obligations or liabilities generally do not have retrospective effect unless expressly specified.
