Cheque dishonour liability requires a legally enforceable debt; unsupported contingent advocate fee claim cannot sustain prosecution.

A prosecution under Section 138 of the Negotiable Instruments Act requires a legally enforceable debt or liability. Where the cheque was alleged to represent an advocate's fee for litigation work, but no contractual document proved a lawful fee arrangement, the claimed amount was treated as prima facie contrary to the Legal Practitioners' Fees Rules, 1973. The presumption under cheque dishonour law did not cure that defect, because a cheque issued towards an unsupported or impermissible contingent fee claim cannot satisfy the statutory requirement of enforceable liability. On that basis, the complaint was held not maintainable and the criminal proceedings were quashed.

Issues: Whether a complaint under Section 138 of the Negotiable Instruments Act, 1881 was maintainable when the cheque was issued towards an alleged advocate's fee claim that was asserted to be contingent and unsupported by any contractual document.

Analysis: The complaint itself proceeded on the footing that the cheque represented a consolidated fee for litigation work. No document evidencing any contractual arrangement for payment of the alleged sum was produced. In the absence of proof of a lawful contractual fee arrangement, the claimed amount was treated as prima facie contrary to the Legal Practitioner's Fees Rules, 1973. On that basis, the cheque could not be said to have been issued in discharge of a legally enforceable liability. The presumption arising under the cheque dishonour provisions did not assist the complainant to sustain a prosecution founded on an illegal fee claim.

Conclusion: The complaint under Section 138 of the Negotiable Instruments Act, 1881 was held not maintainable and the criminal proceedings were quashed in favour of the petitioner.

Final Conclusion: A cheque dishonour prosecution cannot be sustained where the asserted liability itself is not shown to be legally enforceable and rests on an impermissible contingent fee claim.

Ratio Decidendi: A prosecution under Section 138 of the Negotiable Instruments Act, 1881 requires a legally enforceable debt or liability, and a cheque issued towards an unlawful or unsupported contingent fee claim cannot satisfy that requirement.
