MANUFACTURERS' EXPRESS WARRANTY AND ITS ADMINISTRATION: PERSPECTIVE OF COMMERCIAL TRANSACTIONS AND THE APPLICABLE LAWS IN THE UK, NIGERIA AND USA

This article undertakes a comprehensive juridical examination of manufacturers' express warranty as a competitive mechanism in commercial transactions, with particular reference to the legal frameworks governing warranty administration in the United Kingdom, Nigeria, and the United States of America. The work interrogates the conceptual foundations of express warranty, distinguishing it from implied warranty and guarantee, whilst elucidating its operational dynamics as both a contractual term and a competitive device employed by manufacturers in contemporary commerce.The discourse critically analyses the dichotomy between full and limited warranties, examining their legal implications for consumer rights and manufacturer liability. Through doctrinal analysis and comparative methodology, the article investigates the statutory and regulatory architecture underpinning warranty enforcement across the three jurisdictions, with emphasis on the Fair Trading Act 1973, Unfair Contract Terms Act 1977, Consumer Rights Act 2015 (UK); the Uniform Commercial Code 1952, Magnuson-Moss Warranty Act 1975, and Federal Trade Commission Act (USA); and the Federal Competition and Consumer Protection Act 2018, Standards Organisation of Nigeria Act (Nigeria).The work identifies significant lacunae in warranty administration, including the deployment of exclusion clauses, disclaimers, and the "full proof defense" by manufacturers to evade liability for defective products. It examines the tension between manufacturer prerogatives and consumer protection, particularly addressing the juridical challenges posed by the contra proferentem rule, the doctrine of fundamental breach, and the interplay between contractual and tortious liability in product defect cases. The role of regulatory bodies, warranty administrators, and alternative dispute resolution mechanisms in facilitating consumer claims receives critical attention.This scholarly contribution illuminates the difficulties consumers encounter in proving warranty breach, navigating complex administrative procedures, and overcoming multiple defenses available to manufacturers. The article advocates for harmonized legislative intervention to strengthen consumer protection mechanisms, enhance transparency in warranty disclosure, and establish more accessible remedial frameworks. It concludes with recommendations for both manufacturers and consumers to optimize warranty administration whilst balancing commercial imperatives with consumer welfare objectives, thereby contributing significantly to the jurisprudence of product liability and consumer protection law.
